Rapid Reaction

Pyrolysis of the vapour of the cyclic methyl ethyl ketal of l-2,3-butanediol gives butanone as the chief product. Catalysts such as alumina or phosphoric anhydride greatly accelerate this reaction, while catalytic nickel has little effect. It was found necessary to have alkyl or aryl radicals substituted on the 1,3-dioxa-cyclopentane ring to obtain a rapid reaction. The molecule always splits symmetrically with respect to oxygen, and yields up to 90% conversion per single pass were obtained at moderate flow rates with rings substituted in the 2-, 4-, and 5-positions. The compounds tested were the formal, acetal, benzal, 2-ethylhexal, dimethyl ketal, and methyl ethyl ketal of l-2,3-butanediol and the n-butyral of ethanediol.
