Abstract: Tetramethylammonium methyl carbonate(TMAM)was synthesized by using trimethylamine and dimethyl carbonate as
starting materials and methanol as solvent. And then, TMAMC was hydrolyzed to tetramethylammonium hydrogen carbonate
(TMAH).TMAHC was a kind of intemediate of tetramethylammonium hydroxide(TMAH), which was widely used in industrial
catalysis and ele roic inus n e synthesis of T MAMC, reaction emera ure, materials molar ratio and initial nitrogen pressure
were investigated. The optimum reaction conditions was listed as follows: reaction temperature was 120C, trimethylamine and
dimethyl carbonate molar ratio was 1. 1: 1, initial nitrogen pressure was O. 1 Mpa. On this conditions the yield of TMAMC reached
98.4%. In the hydrolysis of TMAMC, the best reaction temperature was 70C, and the related reaction time was 40 minutes
Key words: tetramethylammonium hydrogen carbonate; tetramethylammonium methyl carbonate; trimethylamine; dimethyl
carbonate; tetramethylammonium hydroxide
四甲基氢氧化铵(TMAH)是一种有机碱,因等以。但是到目前为止,超净高纯的TMAH产
