Abstract

:'65: 32'a Time required for olefin evolution to cease. The normal atmospheric pressure in these laboratories. benzylic> allylic> secondary. The reaction temperatures found to be best were about 120-130 “C for the tertiary, benzylic, and allylic types and 160-180 “C for secondary alcohols. Higher temperatures lead to somewhat decreased yields in cases of easily polymerized olefins. The olefin product was collected at atmospheric pressure or ...
