In a jacketed kneader having an inner volume of 10 L and made of SUS-316, 1,140 g of heptane was placed as a solvent and 407 g of zinc oxide was added and they were stirred together till they formed a suspension. While the inner temperature of the kneader holding the suspension was retained at a temperature in the range of 5–30° C., 739 g of acrylic acid was gradually added to the suspension over a period of three hours till the temperature reached 40° C. At 40° C., the ensuant reaction was continued for four hours. Then, while the inner pressure of the kneader was gradually lowered and the inner temperature was raised to 50° C. till the pressure reached 20 Torrs, the reaction solution was distilled for five hours to expel the reaction product and the heptane. Consequently, 1,037 g of zinc acrylate was obtained.
