Abstract

A process for the production of a solid metal soap of the formula EQU M(R--COO)(R"--COO) in which M is at least one metal from the group of Ca, Mg, Cd, Ba, Zn, and Pb; and R and R' are C.sub.8 -C.sub.34 hydrocarbon radicals, by direct synthesis from at least one fatty acid with metal oxides and/or metal hydroxides which comprises maintaining a reaction zone containing a liquid phase comprising fatty acid under reduced pressure, passing a portion of the liquid phase to an external premixing zone, introducing a solid metal oxide and/or metal hydroxide into the liquid phase in the premixing zone, passing the mixture to the reaction zone through an intensive mixing zone, and continuously removing water of neutralization formed by the reaction.
