HYDROSULFURIC CORROSION INHIBITOR Russian patent published in 2004 - IPC

Abstract RU 2243292 C1

FIELD: organic chemistry, petroleum industry.

SUBSTANCE: invention relates to field of synthesis of inhibitors of hydrosulfuric corrosion designated for protection of steel equipment in hydrogen sulfide-containing media. Inhibitor represents product of interaction of N'N-tetramethyldiaminomethane and alkenyl chlorides - 1,3-dichloropropene, 3-chloro-1,2-epoxypropane, 3-chloro-2-methylpropene, 1,3-dichloro-2-methylpropene, N-(alkenyl)-N,N-tetramethyldiaminomethane chloride of the formula:

wherein R means -CH₂-CH=CHCl; ; -CH₂-C(CH₃)=CH₂; -CH₂-CCl=CH₂; -CH₂-CCl=CHCl; -CH₂-CH=CH₂. Invention provides effective utilization of waste in manufacturing methallyl chloride, allyl chloride and epichlorohydrin, reduced energy consumption of process in preparing corrosion inhibitors and simplifying technology of process.

EFFECT: improved preparing method.
