摘要
Vinyl chloride is prepd by reacting acetylene with HHcl in the presence of a Pd cpd catalyst and a (cyclo)aliphatic carboxylic acid amide solvent at temps above room temp. The catalyst is pref PdCl2 and the solvent is N-methylpyrrolidone (NMP). The catalyst is pref used in an amt of 0.1-1.0, esp 0.3-0.8 wt % wrt the solvent. The reaction is pref carried out at 100-200, esp 140-170 deg C using a mol ratio acetylene:HC1 of 1:1 to 1:3, esp 1:1 to 1:1.5
