Catalysed gas phase decompositions. XXIX. 2,2-Dimethoxypropane and trifluoroacetic acid

Abstract

Trifluoroacetic acid catalyses the decomposition of 2,2-dimethoxypropane into methyl isopropenyl ether and methanol at 224-291º with rate: k₂ = 10^14,30 exp(-94980/8.314T) s^-l ml mol^-l The products recombine on being condensed together. The order of catalytic effectiveness is: HBr > CF₃COOH > HC1 » CH₃COOH
