Versuchsvorschrift

In a jacketed kneader made of SUS-316, 10 liters in inner volume, 5,926 g of toluene as an organic solvent and 11.4 g of sodium dioctyl sulfosuccinate (produced by Kao Co., Ltd. and marketed under trademark designation of "Pellex OT-P") as an anionic surfactant were placed, then 1,411 g of zinc oxide was added thereto and stirred to be suspended therein and, with the internal temperature of the kneader kept at 40° C., a solution of 540 g of stearic acid as a higher fatty acid in 1,809 g of toluene was added to the stirred suspension over a period of one hour, and the suspension and the added solution were left reacting for 2 hours. Then, the internal temperature of the kneader was cooled to 15° C. and 2,362 g of acrylic acid was added to the reaction mixture therein gradually over a period of 3 hours so as to elevate the temperature to 35° C. and they were left reacting at 40° C. for 4 hours. The reaction mixture was gradually heated to 50° C. under a reduced pressure so as to allow the pressure to reach 20 Torrs and effect the expulsion of the water formed by the reaction and toluene by distillation over a period of 5 hours and obtain 3,988 g of zinc acrylate containing zinc stearate.
