  • Preparation of acetals
    Patent number: 4209643
    Abstract: A process is described for the production of predominately linear and alpha-branched acetals by reacting a C.sub.3 or higher alpha or internal olefin, carbon monoxide, hydrogen, and a C.sub.1 -C.sub.5 alkanol using a cobalt catalyst in the presence of a promoter which is a quaternary ammonium salt such as N-benzyl,N,N,N-trimethylammonium methoxide. When a quaternary ammonium salt is used, an increase in the rate of reaction is effected.
