%X 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 &#8776; C2H5COOH
