Method of making reduced water content bisoxazolidine hydrogen sulfide scavengers

摘要

A method making sulfhydryl scavenging agents with reduced water content comprising treating the sulfhydryl scavenging agent to remove water. The sulfyhydryl scavenging agent preferably comprises an -N-C-N- moiety produced by condensation of an alkanolamine with an aldehyde. Preferred sulfhydryl scavenging agents are bisoxazolidines.
