PCT No. PCT/EP91/01051 Sec. 371 Date Feb. 16, 1993 Sec. 102(e) Date Feb. 16, 1993 PCT Filed Jun. 6, 1991 PCT Pub. No. WO91/19691 PCT Pub. Date Dec. 26, 1991.A process for the production of a solid metal soap of the formula 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 C8-C34 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.
