| abstract | 1.1-dichlorpropene-1 is made by reacting 1.1.2-trichlorpropane, which may be prepared by the process described in Specification 471,188, with a compound removing hydrogen chloride. Such compounds may be aqueous or alcoholic caustic soda or potash, aqueous alkaline earth hydroxides, or solutions of sodium carbonate, when operating in the liquid phase, or halides of metals such as Ni, Cu, Pb, Cd, Fe, for a gaseous phase reaction. Barium chloride on charcoal may be used at 250--350 DEG C. The liquid phase reaction is preferably effected at elevated temperature, e.g. 77--132 DEG C. In examples: (1) the trichlorpropane is added to aqueous caustic soda in a flask fitted with stirrer and reflux condenser. Temperature is maintained at about 75 DEG C. The oily layer is separated and fractionated; (2) a fractionation column and condenser replace the reflux condenser. Temperature is 78--85 DEG C. and the oily distillate is separated from the aqueous layer, dried, and fractionated; (3) the trichlorpropane is added to ethyl alcoholic caustic potash at room temperature. The precipitate of KCl is removed, the filtrate diluted with water, and the oily layer worked up; (4) a suspension of CaO is used at 85 DEG C., the oil obtained being steam distilled; (5) the trichlorpropane is run through a tube containing barium chloride and charcoal at 300--350 DEG C., HCl being vented and the reaction product condensed. |
