| titleOfInvention | Production of cyclic acetals or ketals using liquid-phase acid catalysts |
| abstract | A process for making a cyclic compounds such as cyclic acetal or cyclic ketones by feeding aldehyde or ketone compounds and polyhydroxyl compounds to a reaction vessel at a molar ratio of polyhydroxyl compounds to aldehyde or ketone compounds of at least 3:1, reacting these compounds in the presence of a homogeneous acid catalyst to generate a liquid phase homogeneous reaction mixture containing the acid catalyst without separating water from the reaction mixture as it is being formed in the reaction mixture, withdrawing the liquid phase homogeneous reaction mixture from the reaction vessel as a liquid product stream, and feeding the liquid reaction product stream to a distillation column to separate cyclic acetal compounds from unreacted polyhydroxyl compounds, and optionally recycling back the unreacted polyhydroxyl compounds and/or acid catalyst to the reaction vessel. The process produces cyclic acetal compounds in high yields. The process is also suitable to make cyclic ketals from ketone compounds. |
