Abstract
Formic and propionic acids
catalyse the decomposition of 2,2- dimethoxypropane into isopropenyl methyl
ether and methanol in homogeneous, molecular reactions at 274-334 and 335-389�C
with rate constants:
������������������ k2 = 1010.62exp(-94030/8.314T)
s-1 ml mol-1
������������������ k2 = 1012.44exp(-124240/8.314T)
S-1 ml mol-1
respectively.��� Carboxylic acids appear to be generally
effective as catalysts, and with this substrate the rate order is:������� ���������������� HBr
> CF3COOH > HCl >> HCOOH >
CH3COOH ≈ C2H5COOH
