HCID 86756468Di(2-mercaptoethyl)ether 1,4-butanedisulfonyl chloride

Procedure

The base particles, along with helium gas, were cooled and introduced through the particle intake 4 into the vapor atmosphere of 1,4-butanedisulfonyl chloride in the condensing chamber 26. Next, in the mixing section 22, the vapor of 1,4-butanedisulfonyl chloride was cooled, and the introduced base particles were exposed thereto for 10 minutes. Consequently, a polymerization reaction, using as a catalyst triethylenediamine contained in the base particles, took place on the surface of the base particles between di(2-mercaptoethyl)ether and 1,4-butanedisulfonyl chloride, forming a film of di(2-mercaptoethyl)ether-1,4-butanedisulfonyl chloride co-polymer.
