Abstract
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.
