摘要:
A method of preserving an aqueous system which is susceptible to microbiological degradation, comprising the step of adding to the system a compound having the formula wherein X is an anion selected from the group consisting of sulfate, acetate and citrate groups, and wherein the compound is added in an amount sufficient to inhibit the growth and proliferation of at least one microorganism in the aqueous system. The compounds 1-methyl-3,5,7-triaza-1-azoniatricyclodecane acetate and 1-methyl 3,5,7 triaza-1-azoniatricyclodecane citrate, and a method for preparing these compounds comprising the reaction of ammonium citrate, or ammonium acetate, with methylamine, formaldehyde and ammonia in an aqueous medium.
摘要:
A method of preserving an aqueous system which is susceptible to microbiological degradation. To the system is added a compound having the formula wherein R and R′ are independently selected from hydrogen or a methyl group, R˝ is a moiety selected from the group consisting of (a) hydrogen, (b) a halogen atom selected from the group consisting of F, Cl, Br and I, and (c) a nitro group; or the hydrochloride salt of the compound. The method disclosed is especially useful for preserving aqueous solutions, emulsions, and suspensions which are susceptible to microbiological degradation.
