Patent ID: 7560600

Claim:
A process for producing a 2,2,4,4-tetraalkylcyclobutane-1,3-diol of Formula II, comprising contacting a 2,2,4,4-tetraalkylcyclobutane-1,3-dione with hydrogen in the presence of a promoted nickel-based catalyst under conditions of temperature and pressure sufficient to form a 2,2,4,4-tetraalkylcyclobutane-1,3-diol, wherein each of the alkyl radicals R 1 , R 2 , R 3 and R 4 has, independently from each other, 1 to 8 carbon atoms and wherein less than 2 mol % of the 2,2,4,4-tetraalkylcyclobutane-1, 3-dione is converted to ring-open products and wherein the promoted nickel-based catalyst comprises a promoter metal chosen from a Group 4 metal.
