Synthesis of vinyl ether compounds by pyrolysis of dimethyl perfluoro-2,7-dimethyl-3,6-dioxa-1,8-octanedioate

Dimethyl perfluoro-2,7-dimethyl-3,6-dioxa-1,8-octanedioate (1) is pyrolyzed over Na2CO3, K2CO3, CaCO3, BaCO3 and ZnO to give mixtures containing perfluoro-3,6-dioxa-1,7-octadiene (2) and methyl perfluoro-2-methyl-3,6-dioxaoctanoate-7-ene (3).The pyrolysis conditions necessary to obtain these vinyl ethers require a higher temperature for the divalent metal compounds than for the monovalent.Increase in the pyrolysis temperature and decomposition time result in an increasing conversion of 1.At lower temperatures the pyrolysis product is mainly 3.However, the formation of 2 increases with increasing decomposition temperature.Dimethyl carbonate was found in the decomposition product of the pyrolysis of 1 over Na2CO3, K2CO3. - Keywords: Pyrolysis; Dimethyl perfluoroalkanedioate; Perfluorodivinyl ether; Methyl perfluorovinylalkanoate; Metal carbonate

Purification of a fluoroalkyl vinyl ether (by machine translation)

PROBLEM TO BE SOLVED: To provide a purification method by which a fluoroalkyl vinyl ether is efficiently separated by using a specified treatment agent whose final removal is not needed. SOLUTION: A crude fluoroalkyl vinyl ether containing a hydrogen fluoride addition product of fluoroalkyl vinyl ether is distilled in the presence of 1 to 10 wt.% amines to the crude fluoroalkyl vinyl ether, having a boiling point higher than that of fluoroalkyl vinyl ether by 70°C or more. The fluoroalkyl vinyl ether contains fluoroalkyl monovinyl ether and fluoroalkylene divinyl ether. COPYRIGHT: (C)2013,JPO&INPIT
