Triethylamine methanol azeotrope
Webthe azeotropic mixture of formic acid (HCOOH) and triethylamine (NEt3) (F-T), in which the F/T molar ratio is 2.5:1 [5d,h,i,8a,c,13]. A drawback regarding ATH in IPA is the reversibility of the reduction process. The equilibrium is regulated by the oxidation poten-tials of the relevant carbinol/ketone couples. The reaction gives a WebDec 21, 2024 · Methyl acetate is considered low toxicity volatile solvent produced either as a by-product during methanol carbonylation or via acetic acid esterification with methanol. In both cases, pure methyl acetate has to be isolated from the reaction mixture. Simulation of methyl acetate separation from its mixture with methanol by extraction distillation was …
