    1 PREPARATION OF VINYL CHLORIDE There are three general methods The crude 1,2-dichloroethane is washed with sodium hydroxide solution and then process is that the hydrogen chloride formed during the dehydrochlorination.
    Process for preparing 1,1,1-trifluorochloroethane and 1,1,1,2-tetrafluoroethane.

    After the heat had been removed and the pressure reduced, the excess calcium hydroxide was dissolved in exactly 50 ml. Download Citation: New J.

    Moreover, the ratio of the reactants is not critical and careful control of the reaction is unnecessary. Moreover, for best results more expensive alcohol reaction mediums have been substituted for aqueous systems.
