Abstract

Methyl, ethyl, or propyl esters of carboxylic acids with more than 4 carbon atoms, are prepared by reacting ethylene and/or propylene, carbon mon-oxide and ROH (R = H or CH3) under superatmospheric pressure in the presence of an aqueous (70-80%) HBF4 solution, or methanolic (55-75%) HBF solution. When ethylene is used esters of the C5, C7, C9, C11 carboxylic acids are formed, and when propylene is used C4, C7, C10, C13 carboxylic acid esters are formed, if a mixture of the two is used the acid residue contains an even number of carbon atoms. The process may be continuous with liquified olefines and examples describe the preparation of ethyl esters of a -methyl - a - ethylbutyric and a - methylbutyric acid; isopropyl esters of isobutyric acid, and C7-carboxylic acids; methyl esters of C5, C7, C9- -13 and above C13 carboxylic acids; methyl esters of isobutyric acid, C7-, C10- and C13-carboxylic esters.
