| Synthesis | 2077-46-5 50-31-7 The general procedure for the synthesis of 2,3,6-trichlorobenzoic acid from 2,3,6-trichlorobenzene was as follows: 2,3,6-trichlorobenzene was added to 100 mL of water, followed by the addition of 0.4 g of tetrabutylammonium chloride as a phase-transfer catalyst, and 63 g of potassium permanganate. The reaction mixture was heated to 50 °C for 6 hours. Upon completion of the reaction, the pH of the filtrate was adjusted to 3 with 5% hydrochloric acid solution (mass percent, as HCl), at which time a large amount of white solid precipitated. The precipitate was collected by filtration, washed with a small amount of water and dried to give 43.3 g of 2,3,6-trichlorobenzoic acid with 95% purity and 96% yield by HPLC. |
| Environmental Fate | Photolytic. Plimmer (1970) postulated that the irradiation of 2,3,6-trichlorobenzoicacid in methanol will undergo dechlorination forming 2,3-, 2,6- and 3,6-dichlorobenzoicacids. Further irradiation may yield 2- and 3-chlorobenzoic acids which may ultimatelyform benzoic acid (Plimmer, 1970). Chemical/Physical. Reacts with alkalies and amines forming water-soluble salts. |
