ABSTRACT:
Tetrahydrofurans are produced by (a) contacting gamma-chloroalkanols with an aqueous protonic solution by which the chloroalkanol is cyclized to form a tetrahydrofuran and (b) removing the resultant tetrahydrofuran from the reaction mixture. The gamma-chloroalkanol is preferably derived by free radical chlorination of alkanols in the presence of 50-96% wt. sulfuric acid.
