| titleOfInvention | Improvements in the manufacture of acetyl-chloride |
| abstract | Acetyl chloride is prepared by the interaction of liquid acetic acid and gaseous phosgene at a raised temperature and approximately normal pressure under conditions whereby the acetyl chloride produced is continuously removed by evaporation. As catalysts for the reaction, use may be made of such compounds of metals of the second and third periodic groups as are soluble in hot acetic acid, e.g. magnesium oxide, anhydrous calcium chloride, or aluminium acetate. Examples are given in which the reaction is effected at 80 or 110 DEG C. in a vessel connected to a condenser which returns any acetic anhydride formed to the vessel, the acetyl chloride and the gaseous reaction products passing from the condenser to a refrigerator, and fresh acetic acid being continuously run into the vessel; the phosgene may be passed in through a porous plate in the vessel, and the gaseous reaction products undergoing cooling may be washed with a liquid which absorbs acetyl chloride without absorbing much hydrogen chloride; suitable washing liquids are mixtures of acetic acid and acetic anhydride and also hydrocarbons and their halogen- or nitro-derivatives, such as chloronaphthalene. |
