| Abstract: | Three different methods for purification of raw benzocyclobutene (BCB) mixture obtained from pyrolysis of o-methylbenzyl chloride were investigated. The better method was found to be the treatment of raw BCB mixtures with H_2SO_4 and the optimal purification conditions were found as follows: c(H_2SO_4) is 80%, reaction temperature is 20℃, reaction time is 120 min. The removal of phenylacetylene and styrene are 100% and 90% respectively, and the recovery of BCB is about 76%. The chemical structure of refined BCB was identified. |
