  • Fatty acid halide manufacture
    Patent number: 5247106
    Abstract: The invention is concerned with a process for preparing a C.sub.6 to C.sub.24 fatty acid halide by reacting a fatty acid with a halogenating agent, such as phosphorus trichloride, optionally followed by hydrolysis of unreacted halogenating agent separating and removing an inorganic lower layer to leave a turbid layer containing the fatty acid chloride product. The clearing time of the turbid layer is reduced by the addition of from 3 to 20% by weight of clear fatty acid halide thereto.
