Versuchsvorschrift

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.
