Procedure: 130 kg of zinc oxide is dispersed in a rotor-stator shear machine with 16 liters of 25% aqueous ammonia in 480 liters of cold water with simultaneous introduction of gaseous carbon dioxide. Simultaneously, 900 kg of molten stearic acid is emulsified at 80° C. in 180 liters of water and to the emulsion there is added 36 liters of 25% aqueous ammonia. Both dispersions are fed at 80° C. through correspondingly adjusted dosing pumps to a rotor-stator shear machine likewise heated to 80° C., so that stoichiometric amounts are reacted per unit of time. From the 130 kg of zinc oxide and 900 kg of stearic acid (saponification number=204) there is formed 1000 kg of zinc stearate. The pasty zinc stearate drawn off from the rotor-stator shear machine has a water content of about 45%. It is fed directly to a flowing air dryer in which it is dried to a water content of 0.2%. The end product is a finely granular, extremely pure, electrolyte-free zinc stearate. are fed at 80° C. through correspondingly adjusted dosing pumps to a rotor-stator shear machine are reacted per unit of time

Procedure: A mixture of iron powder and zinc stearate and a mono, di or triester of phosphoric acid and long-chain alcohols, such as a mixture of phosphoric acid monostearyl ester and phosphoric acid distearyl ester having a melting point of 70° C., as antitack agent was pressed to form a molded article, the proportion of the antitack agents with respect to the weight of the iron powder being approximately 1.7% by weight, and the atomic ratio Zn:P being approximately 3:2. The molded article was heated in a nonreducing atmosphere, such as in nitrogen, to a maximum temperature of approximately 550° C., the antitack agents pyrolyzing to ZnO and P2O5, and the oxides reacting with each other to form zinc phosphate. As was determined, zinc phosphate has a high specific electrical resistance, adheres well to metals and protects especially iron from corrosion. The composite material obtained is suitable as a soft magnetic material for fast-acting electric valves. to form a molded article

Procedure: 1,145 parts of stearic acid is added to 5,000 parts of ethanol, and the mixture is mixed at 75° C. 200 parts of zinc hydroxide is added thereto in small amounts, and the mixture is mixed for one hour from the point of completion of introduction. After the mixing, the mixture is cooled to 20° C., and the product is separated by filtration to remove ethanol and reaction residues. The solid product taken therefrom is dried for 3 hours at 150° C. using a heating type vacuum dryer. The product is removed from the dryer and is cooled naturally. Thus, solid zinc stearate is obtained. the mixture is mixed at 75° C in small amounts, and the mixture is mixed for one hour from the point of completion of introduction the product is separated by filtration to remove ethanol and reaction residues The solid product taken therefrom is dried for 3 hours at 150° C.

Procedure: The procedure of Example 1 was essentially repeated using glycerol (66.67 cm3) and acetic acid (0.064 g; to pH 4.8) but with zinc stearate (16.67 g) instead of zinc oxide. Zinc stearate does not form zinc oxide under the reaction conditions employed. The slurry was heated at 100° C. for 2 hours, centrifuged with 4 washes, and dried at 80° C. to produce a white powder. From analysis using IR spectroscopy it was found that no glycerato complex was obtained.

Procedure: 32.5 grams of a formulated Sulfo-EPT composition, 17.5 grams of HDPE, and 8.1 grams of stearic acid were blended in a Brabender mixing head for 13 minutes at 160° C and 50 rpm. This blend was placed in a rubber mill and 2.6 grams of zinc acetate were added over a one minute time period while milling at 160° C. After the zinc acetate was completely added, the total blend was milled for an additional 31/2 minutes at 160° C. The Sulfo-EPT composition used in this experiment contained 30 milliequivalents of acid groups, and had been neutralized with 3 equivalents of magnesium hydroxide prior to blending. The amount of zinc acetate and stearic acid was sufficient to yield 3 equivalents of the preferential plasticizer zinc stearate. mixing head for 13 minutes at 160° C were added over a one minute time period while milling at 160° C the total blend was milled for an additional 31/2 minutes at 160° C

Procedure: A method of forming an aqueous dispersion of particles of zinc stearate includes the steps of forming a mixture of at least one surfactant and water, heating the mixture to a temperature of from about 40° C. to less than a melting temperature of zinc stearate, adding a metal-containing stearate to the mixture under agitation, adding to the mixture a solution of a zinc salt in water, whereby upon inclusion of both the metal-containing stearate and the zinc salt in the mixture, the zinc salt reacts with the metal-containing stearate to form the particles of zinc stearate, continuing the heating and agitation following completion of the latter of the adding of the solution of zinc salt or the adding of the metal-containing stearate to continue the reaction, and cooling to obtain the aqueous dispersion of particles of zinc stearate. The method forms a stable aqueous dispersion of nanometer sized zinc stearate particles particularly useful in coating toner particles. the reaction cooling
