ABSTRACT:
The invention provides a process for preparing fatty acid halide by reacting a fatty acid with a halogenating agent optionally followed by hydrolysis of unreacted halogenating agent and separating the fatty acid halide upper layer from the inorganic lower layer characterized in that a fatty acid nitrogen derivative, preferably a fatty amide has been incorporated in the reaction mixture. Preferably the fatty acid is a saturated or unsaturated C.sub.6 to C.sub.24 fatty acid and the halogenating agent a phosphorus halide, especially phosphorus trichloride.
