Patent ID: 8692042

Claim:
A method for producing cycloheptatriene comprising: (a) combining at least 7,7-dichloronorcarane and a liquid component in a container to form a reaction combination, wherein the container has a gas inlet and a gas vent, and the liquid component comprises a C 8 to C 30 succinic anhydride, a carboxylic acid, or a C 8 to C 30 alkyldimethylamine; (b) while passing gaseous nitrogen through the reaction combination in the container via the gas inlet and the gas vent at a rate up to about 100 mL/min, heating the reaction combination to, and maintaining the reaction combination at, about 205 deg. C. to about 230 deg. C.; (c) collecting distillate from the container; and (d) obtaining cycloheptatriene from the distillate.
