Abstract
Urethanes are prepd. by reacting an organic cpd. having >=1 hydroxy gp. with carbon monoxide, and a nitrogen-contg. organic cpd., at elevated temp. and pressure in the presence of selenium, sulphur, a selenium cpd., a tollurium cpd. or a sulphur cpd., and a base and/or water. High yields of pure urethanes, including polyurethanes are obtd. by the relatively non-toxic process; and by controlling the reaction conditions amines can be produced simultaneously.
