MANUFACTURE OF 1,3-PROPANEDIOL ESTERS

Disclosed is a process for manufacturing an ester of 1,3-propanediol, comprising, contacting at a temperature of about 0 DEG C. to about 250 DEG C., ethylene, formaldehyde or a form of formaldehyde, a carboxylic acid, and a compound of the formula MZn.Qt, wherein: M is a zirconium[IV], cobalt[II], vanadium[IV], bismuth[II], tin[II], a rare earth metal, scandium or yttrium; n is the oxidation state of M; at least one of Z is an anion of the formula R1SO3- or R1CO2-, wherein R1 is hydrocarbyl or substituted hydrocarbyl containing 1 to 20 carbon atoms or part of a polymer, and the remainder of Z is oxo or one or more monovalent anions; Q is a neutral ligand; and t is 0 or an integer of 1 to 12.
