The reaction between aromatic acid halide and acetylene in the presence of aluminum chloride can be made to proceed smoothly by the addition of a small amount of mercuric chloride as a promoter. Phenyl-β-chlorovinylketone has been prepared in a good yield by the present method. Sulfuryl chloride reacts with acetylene under the same condition to give chlorosulphonyl vinyl chloride. Acyl chloride reacts with acetylene under this condition to give a much better yield increasing from...

The reaction between aromatic acid halide and acetylene in the presence of aluminum chloride can be made to proceed smoothly by the addition of a small amount of mercuric chloride as a promoter. Phenyl-β-chlorovinylketone has been prepared in a good yield by the present method. Sulfuryl chloride reacts with acetylene under the same condition to give chlorosulphonyl vinyl chloride. Acyl chloride reacts with acetylene under this condition to give a much better yield increasing from 55% to 80-87%, and the time required to complete the reaction is 2-2 hrs. and 20 mius. in contrast to 6 hrs. as required by the old method.The physical constants of phenyl-β-chlorovinyl ketone obtained by Nesme-jannoff and others are different from those obtained by the present method. This is probably due to the formation of two different geometrical isomers by the two different methods.

运用氯化汞为醯卤与乙炔加成时的促进剂,实现了芳香醯卤(苯甲醯氯为代表)与乙炔的反应,以良好的收率得到了苯-β-氯乙烯酮。实现了前人失败了的二氯砜与乙快的加成反应,制得了β-氯乙烯氯砜。以HgCl_2促进氯化乙醯与乙炔的反应时,加快了反应速度(6小时缩短至2点20分),提高了收率(从55%而达80—87%)。 用我们的方法所制得的苯-β-氯乙烯酮和用等的方法制得者物理常数不同。可能这二者的不同是由於反顺异构体的关系。

Phosphonic cation exchange resins, of differert diameters from 0.15 to 0.75mm., with various degree of cross-linking, have been prepared by the copolymeriza-sion of styrenedivinylbenzene, followed by the reaction with phosphorus trichloridein the presence of aluminum chloride, and finally by the oxidation with nitricacid. The capacity, swelling, and moisture content vary inversely with increaseof the degree of cross-linking and with the particle size of the resin. From the results of phosphorus analyses and capacity determination, it isthown that each benzene ring contains approximately 0.76--0.85 atom of phos-phorus which exists mainly as phosphonic acid. The potentiometric titrationcurve proves that the resins are dibasic acids.
