Abstract

See full text

Disclosed is a process for the preparation of a 2,2,4,4-tetraalkylcyclobutane-1,3-diol by hydrogenation of the corresponding 2,2,4,4-tetraalkylcyclobutane-1,3-dione in the vapor phase in the presence of a supported catalyst. The process is useful for the preparation of 2,2,4,4-tetramethylcyclobutane-1,3-diol from 2,2,4,4-tetramethylcyclobutane-1,3-dione. The process can produce a 2,2,4,4-tetraalkylcyclobutane-1,3-diol product having a cis:trans isomer ratio of 1:1 or greater.
