CA 2667353

Oxazolidinium compounds are formed by the reaction of a halohydrin or an epoxide with a secondary amine and an aldehyde or a ketone. The oxazolidinium compounds are formed directly and do not require the reaction of a pre-formed oxazolidine with an alkylating agent. The compounds are useful as gas hydrate inhibitors in oil and gas production and transportation.

L'invention concerne des composés d'oxazolidinium formés par réaction d'une halohydrine ou d'un époxyde avec une amine secondaire et un aldéhyde ou une cétone. Les composés d'oxazolidinium sont formés directement et ne nécessitent pas la réaction d'une oxazolidine préformée avec un agent d'alkylation. Les composés sont utiles en tant qu'inhibiteurs d'hydrate de gaz lors d'une production et d'un transport de pétrole et de gaz.
