  • Concurrent production of trichloroethane isomers
    Patent number: 6150573
    Abstract: 1,1,1-Trichloroethane (viz., methylchloroform) and 1,1,2-trichloroethane are produced in the same reactor by feeding molecular chlorine and chloroethene (viz., vinyl chloride) as well as 1,1-dichloroethane to the reactor. The ratios at which the two trichloroethanes are produced can be easily controlled by controlling the relative ratios of 1,1-dichloroethane and chloroethene introduced to the reactor. The reactions are conducted in the liquid phase in the presence of free radical initiator.
    Type: Grant
    Filed: January 5, 1995
    Date of Patent: November 21, 2000
    Assignee: PPG Industries Ohio, Inc.
    Inventors: Tommy G. Taylor, J. Douglas Mansell, John P. Shamburger, Mark E. Woodyear
