Abstract
High purity ethylene is prepared by contacting ethyl acetate with a perfluorosulfonic acid resin catalyst at 150.degree.-250.degree. C.
Claims4
Process for making ethylene in high purity which comprises contacting ethyl acetate at a temperature of 150.degree. C. to about 250.degree. C. with a catalytic amount of a perfluorosulfonic acid resin catalyst, which is a copolymer of tetrafluoroethylene and a sulfonyl fluoride vinyl ether, at a contact time of at least about 1 second and continuously removing ethylene and acetic acid.
