Title:
STABILIZATION OF CATALYST FOR ACETIC ACID PREPARATION, AND METHOD FOR PREPARING AMIDE OF ANHYDROUS TERTIARY AMINE
Document Type and Number:
WIPO Patent Application WO/2017/078507
Kind Code:
A2
Abstract:
The present invention relates to a method for efficiently synthesizing acetic acid by using a catalyst (rhodium, iridium, cobalt, nickel, palladium, platinum, or ruthenium) which is used in acetic acid preparation and undergoes an oxidative addition reaction with an alkyl halide, wherein trimethylamine is added such that the stability of the catalyst is not limited by the moisture concentration inside a reactor. The present invention further relates to a method for using an extremely small amount of a halogen promoter to synthesize dimethylacetamide at high catalytic efficiency without consumption, by using the same catalyst and carbonylating, under carbon monoxide pressure, anhydrous trimethylamine with moisture removed. The present invention still further relates to a method for using an extremely small amount of a halogen promoter to synthesize a tertiary amide at high catalytic efficiency without consumption, by carbonylating, under carbon monoxide pressure, an anhydrous tertiary amine with moisture removed.
