Abstract
Disclosed is a novel process for the manufacture of 2,2,4,4-tetramethylcyclobutanediol commencing with the pyrolysis of isobutyric anhydride to produce dimethylketene. Dimethylketene is absorbed into certain carboxylate ester solvents which function as the process solvents for subsequent dimerization of the dimethylketene to 2,2,4,4-tetramethylcyclobutanedione followed by the catalytic hydrogenation of the dione to the diol product.
