Procedure

Five parts of 3,5-di-t-butyl-2-methoxybenzoic acid was added to 48 parts of water, followed by the dropwise addition of an aqueous solution of 1.2 parts of 96% potassium hydroxide in 2 parts of water. The resulting mixture was converted into a solution by heating to a temperature of 40° to 50° C. An aqueous solution of 2.7 parts of zinc sulfate heptahydrate in 10 parts of water was dropped into the solution at 60° C. over a period of 15 minutes. After the completion of the dropping, the obtained mixture was stirred at that temperature for 2 hours, cooled to a room temperature and filtered to recover a white crystalline precipitate. This precipitate was dispersed in 60 parts of water, washed therewith and filtered. The filter cake was dried to give 3.8 parts of a white crystal. The melting point thereof was 263° to 265° C.
