| Description | Crude oil is a complex mixture of chemicals. The relativecomposition of these chemicals is different in crude oil fromdifferent sources. However, the overall composition remainsfairly consistent between sources. The chemical classes presentin crude oil include paraffinic hydrocarbons, long-chainstraight or branched carbon-based chemicals and naphthenichydrocarbons, multiple-ringed carbon-based chemicals. Crudeoil contains more than 30 parent polycyclic aromatic hydrocarbons(PAHs). The United States Environmental ProtectionAgency has designated 16 of them as priority pollutants andclassified 7 of them as probable human carcinogens. Lowpercentages of sulfur, nitrogen, and oxygen compounds, andtrace quantities of many other elements such as metals(cadmium, mercury, lead, vanadium, nickel) are also present.The petroleum crude category contains only CAS Number8002059 to identify all conventional crude oils and thosederived from tar sands, regardless of source or hydrocarbondistribution. Regulatory agencies have classified crude oil into categories(summarized in Table 1) that are useful to help understandhow the oil will behave if released into the environment.However, weather conditions and water temperature greatlyinfluence the behavior of oil in the environment and a Class Boil may become a Class C oil as volatiles evaporate, whereasa Class C oil may solidify and resemble a Class D oil at lowtemperatures (e.g., upon going deeper in the sea). |
| Chemical Properties | Rubber solvent is a clear, colorless, and flammable liquid,somewhat less volatile than petroleum ether. |
| Uses | Rubber solvent is used as a solvent in the manufacture ofadhesives, brake linings, rubber cements, tires, intaglio inks,paints, and lacquers, and in degreasing operations. |
| Uses | The world production of crude oil per year is of the order of 3–4billion tons per year, of which about half is transported by sea.The separation of the components of crude oil into useableproducts is known as refining. Each of the crude oil fractionsfinds its way into consumer products. A typical list of fractionsis gasoline, kerosene and fuel oil, gas oil, wax distillate, andbottoms or asphaltics. Refineries must be designed to handlethe type of crude oil they are going to process. For example, ifa crude oil is highly paraffinic in nature, it will yield a loweramount of gasoline fuel by distillation. Highly paraffinic oilsmay be processed into lubricating stock. The chemical fractionconsisting of chemicals with the largest carbon numbers, theasphaltic fraction, is used as roof or road tar. |
| Definition | Lubricant base is a complex combination of hydrocarbons. It consists predominantly of aliphatic, alicyclic and aromatic hydrocarbons. It may also contain small amounts of nitrogen, oxygen and sulfur compounds. This category encompasses light, medium, and heavy petroleums, as well as the oils extracted from tar sands. Hydrocarbonaceous materials requiring major chemical changes for their recovery or conversion to petroleum refinery feedstocks such as crude shale oils, upgraded shale oils and liquid coal fuels are not included in this definition. |
| General Description | Colorless liquid with a gasoline- or kerosene-like odor. A mixture of paraffins (C5 to C13). May contain a small amount of aromatic hydrocarbons. Flash point ranges from -40° F to -86° F Petroleum oils comprise a mixture of hydrocarbons including the liquid paraffin series,CsH12 toCI6H34, the cycloparaffin or naphthene series, C17H36 to C27H56, and the gases,CH4 to C4H10. Petroleum is a heavy, flammable oil that is formed by the decomposition of animal and plant remains by fermentation or bacterial action in a low-temperature, high pressure reaction. Crude oil maybe designated as "sour" if it contains sulfur compounds. Petroleum is used mainly in the production of fuels and lubricants, but also provides raw materials for a wide range of chemicals called petrochemicals. |
| Air & Water Reactions | Highly flammable. Insoluble in water. |
| Reactivity Profile | Saturated aliphatic hydrocarbons, which are contained in Lubricant base, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water. May be ignited by strong oxidizers. |
| Health Hazard | Vapor irritates respiratory tract, causes coughing and mild depression. Aspiration causes severe lung irritation with coughing, gagging, and rapidly developing pulmonary edema. Ingestion irritates mouth and stomach, causes nausea, vomiting, swelling of abdomen, cardiac arrhythmias. |
| Safety Profile | Questionable carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data by skin contact. A dangerous fire hazard when exposed to heat, flame, or powerful oxicllzers. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See I also MINERAL OIL. |
| Environmental Fate | A small fraction of the petroleum products is released to land,either accidentally or intentionally. Release of refined oils,particularly gasoline, from leaking underground storagetanks is the most widely recognized source of petroleumcontamination of soils and groundwater. In contrast, over 2million tons of oil per year enter the marine environmentfrom all sources. Anthropogenic sources (~85%) includechronic discharges (storage facilities, refineries, tankers),accidental oil spills and to a lesser extent, river-bornedischarges, and diffuse discharges (industry, offshore oilplatforms, atmosphere). The main source of chronicdischarges offshore is produced water, the maximumpermitted concentration of crude oil in discharged producedwater being 30 mg l-1. Following release to the environment, petroleum productsmay accumulate in soils and sediments where they undergodispersal and weathering (changes in physical and chemicalproperties). Crude oil spilled on water also undergoesweathering. Weathering affects the composition and toxicity of thehydrocarbon mixtures, occurs by abiotic (volatilization andoxidation) and biotic processes (including biodegradation),and begins immediately after crude oil is released into theenvironment. Its chemical-specific properties will determinehow an individual compound of crude oil fares duringweathering. Small volatile compounds are lost first from bothland and water releases whereas large paraffinic compounds aremore persistent and asphaltic compounds are the residualmaterial. Heavy fractions with high density may adsorb tosuspended solids and sink into the sediment. This happensafter the initial removal of the smaller and more volatilechemicals by either dissolution or volatilization. Persistencedepends on the type of oil, the season, the geomorphology ofthe coast and the degree of exposure, and goes from some fewto many decades. After 20 years, most of the oil spilled byExxon Valdez was eliminated due to natural weatheringalthough some subsurface oil residues, sequestered and slowlyaffected by natural weathering, remained. Although controversial due to the well-known side effectsand toxicity, the judicious and proper application of chemicaldispersants may accelerate the dispersion of crude oil from thesea surface into the water column, which in turn helps toaccelerate its dilution, weathering, and biodegradation. Biodegradation is a major process that removes hydrocarbonsreleased into both soil and aquatic environments.However, the biodegradation of crude oil is only efficient whencrude oil concentrations are low. It may last for decades andrequires the simultaneous action of different microbial populations,including fungi and bacteria. Biodegradation rates forcrude oils will vary considerably, but in standard 28-daystudies, none would be expected to be readily biodegradable.Most of the nonvolatile constituents of crude oil are inherentlybiodegradable but some of the highest molecular weightcomponents are persistent in water. n-Alkanes are utilized asfood by many marine microbes and readily biodegraded inseawater. Branched-chain or iso-alkanes are less biodegradablebut they do ultimately biodegrade. Cycloalkanes and aromatichydrocarbons are resistant to biodegradation, but a fewmicroorganisms are able to utilize them. High molecularweight compounds, the tars and asphaltenes are practicallyreluctant to ultimate biodegradation and persist in the environment.In soils, 25% total PAHs of spilled crude oil can benaturally removed by soil microorganisms within a period of 9months under optimal conditions, but the time needed toeliminate the remaining PAHs may also extend to decades.Biodegradation can be enhanced by the presence or earthwormsand other soil invertebrates that contribute to optimizemicrobial habitats and by artificially adding nutrients to stimulatemicrobial action. |
| Toxicity evaluation | The concern for both dermal and inhalation exposures is the siteof contact and effects on that tissue. The mechanism of crude oiltoxicity is mediated through its irritant effects which after sufficientexposure duration and concentration result in tissuehyperplasia. Chronic hyperplasia leads to subsequent loss oftissue integrity and damage and in someanimalmodels of cancer.It has been suggested that at exposures below levels that causechronic irritation, other long-termeffects would not be expected. Although studies on the mechanisms of toxicity of crudeoils are relatively few, there is a substantial body of data onproducts derived from crude oils, such as gasoline, diesel fuels,kerosene and jet fuels, lubricating oils, and white oils. Extrapolationfrom these studies provides insight into biologicallyactive components of crude oils. Crude oil contains manychemicals considered toxic and the effects of these individualchemicals should be evaluated if exposure is possible.Although polar- and nonpolar compounds contribute to thetoxicity of (weathered) crude oil, the water-soluble fraction(WSF) is dominated by polar compounds, which accounts fora large portion of the toxicity. Crude oil toxicity can vary depending on environmentalfactors. For instance, exposure of crude oil to sunlight enhancesthe toxicity of its WSF because this contains some hydrocarboncompounds that are phototoxic or exhibit at least photoenhancedtoxicity. |
