Abstract
The invention relates a process for the carbonylation of epoxides by reaction with carbon monoxide in the presence of a catalyst system containing a source of cobalt and a hydroxy substituted pyridine compound, whereby .beta.-propiolactones and/or derivatives thereof, such as .beta.-propiolactone polymers, .beta.-hydroxy carboxylic acids and esters, and .beta.-alkoxy carboxylic acids and esters, are produced.
