Paragraph 0033-0034, (2019/06/07)
The invention discloses a preparation method of 2-isopropyl-2-adamantanol (methyl) acrylate, and the method is characterized in that the 2-isopropyl-2-adamantanol (methyl) acrylate is prepared from (methyl) acrylate and isopropyl adamantane alcohol as reaction raw materials by taking an alkaline compound as a catalyst and carrying out ester exchange reaction at 40-120 DEG C in the presence of a solvent, wherein the alkaline compound catalyst is loaded on a porous carrier; the reaction liquid is filtered by a plate-type filter at 60-80 DEG C and then is cooled to a temperature of -60 DEG C to 0DEG C, and a separated solid is the 2-isopropyl-2-adamantanol (methyl) acrylate. According to the invention, the alkaline compound is used for loading a porous catalyst, the production process stepsare simple, the reaction is thorough, the yield is up to more than 95%, the purification process is simple, the purity of the product reaches more than 98%, the solvent and the catalyst can be recycled, the production cost is saved, and the preparation method realizes zero emission of pollutants, and is a green production method.

Paragraph 0043, (2019/04/18)
PROBLEM TO BE SOLVED: To provide a method for producing an adamantyl (meth)acrylate compound having an extremely high purity at a high recovery rate. SOLUTION: The method for producing an adamantyl (meth)acrylate compound comprises subjecting a crude adamantyl (meth)acrylate compound produced by reacting a compound represented by the general formula (a) as given below and (meth)acrylic acid or the like to a first crystallization using at least one kind of water-soluble organic solvent and then adding water in an amount of 100 to 1 pt.mass based on 100 pts.mass of the water-soluble organic solvent to subject the same to a second crystallization. (In the formula, R1 represents H or a 1-10C alkyl group; M represents H, an alkali metal or MgX (X is halogen).) SELECTED DRAWING: None COPYRIGHT: (C)2019,JPOandINPIT
