Procedure: An aqueous magnesium acetate solution was prepared by adding 1.07 g of magnesium acetate tetrahydrate as a Group 2 or 3 element compound to 30 g of ion-exchanged water and then stirring this solution with a homomixer T. K. ROBOMIX (manufactured by PRIMIX Corporation). Then, 0.44 g of 3-aminopropyltriethoxysilane (KBE-903 manufactured by Shin-Etsu Chemical Co., Ltd.) as a silane coupling agent was gradually added to the aqueous solution. This mixture was subsequently stirred for 5 hours to induce hydrolysis and a condensation reaction of the silane coupling agent, thereby producing a suspension containing a composite compound which contained magnesium and silicon. This mixture was subsequently stirred for 5 hours hydrolysis producing a suspension containing a composite compound which

Crushed maleic anhydride (1.92 parts) was added to a solution of 1 part m-phenylenediamine and 13 parts acetone over a 15-minute period. The heterogeneous reaction mixture was stirred at 40° C. for 1 hour. Acetic anhydride (2.44 parts), 0.32 part triethylamine, and 0.04 part magnesium acetate tetrahydrate were added all at once. The temperature was raised to 60° C. using a heating mantle and maintained for 4 hours. The reaction mixture was cooled, 20 parts water added, and the precipitated product isolated by filtration using a vacuum filter funnel. The filter cake was washed with water and dried for 24 hours at 60°-70° C. in a vacuum oven. A 74% yield of N,N'-m-phenylenedimaleimide, m.p. 203°-204° C. was obtained.

Procedure: Magnesium acetate tetrahydrate (4.28 g) is added to 200 grams of deionized water. The pH of the resulting solution is 8.02.

Procedure: First, 60 g of hydrated alumina (trade name: Disperal HP14 available from Sasol Ltd.) was added to 800 g of pure water, and 1.29 g of magnesium acetate tetrahydrate (element content of Mg/element content of Al=0.006) was added to the resultant mixture. The resultant dispersoid was dried by a spray-drying method to obtain hydrated alumina 1 which magnesium acetate adhered to. The drying temperature (gas phase temperature) was 170° C. The acid site strength of the hydrated alumina 1 was measured by temperature-programmed desorption (TPD) that determines surface activity using ammonia gas. As a result, the presence of acid sites was not confirmed, and it was found that magnesium acetate adhered to hydrated alumina. The resultant dispersoid was dried by a spray-drying method
