Abstract
An alkenediol is produced from an alkenol by contacting the alkenol with formaldehyde at a pH maintained between about 4 and 7. Preferably this pH range is maintained by adding a buffering agent composed of a weak acid and the salt of a weak acid. Particularly advantageous buffering agents are the lower organic polycarboxylic acids with disodium or dipotassium hydrogen phosphate and sodium or potassium dihydrogen phosphate with disodium or dipotassium hydrogen phosphate.
