  • Process to produce vinylidene chloride using phase transfer catalyst
    Patent number: 5396002
    Abstract: The invention concerns a process for producing unsaturated compounds from chlorinated alkanes by dehydrochlorination wherein a phase transfer catalyst is used during reaction of chlorinated alkane with aqueous base. After dehydrochlorination, the products are distilled or flashed off. Then, the phase transfer catalyst is recovered and reused by extracting the catalyst from spent aqueous base with fresh chlorinated alkane and using the mixture of chlorinated alkane and catalyst from the extraction as feedstock.
