| Uses | In compressed form as a fuel instead of alcohol; molluscicide. |
| Definition | A solid compound,C4O4H4(CH3)4, formed by polymerizationof ethanal (acetaldehyde) in diluteacid solutions below 0°C. Thecompound, a tetramer of ethanal, isused in slug pellets and as a fuel forportable stoves. |
| Definition | A polymer ofacetaldehyde in which n usually is 4–6. |
| Hazard | Flammable, dangerous fire risk. Strong irritant to skin and mucous membranes. |
| Carcinogenicity | There is no evidence in the literaturethat metaldehyde has carcinogenic potential. |
| Environmental Fate | Plant. When applied to citrus rinds, 50% was lost after 4.6 days for the first 33 daysand an additional 25% was lost 14 days for the subsequent 26 days (Iwata et al., 1982).Chemical/Physical. Metaldehyde can be converted to acetaldehyde by heating to 150°Cfor 4–5 hours or by the reaction of concentrated hydrochloric acid (6 M) for a couple ofminutes (Booze and Oehme, 1985). |
