On May 31, 2007, Zhao, Qian; Zheng, Jiaming; Gao, Tongwen; Bai, Yunfei; Hou, Chaojun published an article.Computed Properties of 1985-51-9 The title of the article was Synthesis of neopentyl glycol dimethacrylate catalyzed by sodium bisulfate. And the article contained the following:
Neopentyl glycol dimethacrylate was synthesized by esterification of methacrylic acid and neopentyl glycol over sodium bisulfate catalyst. Influence of reaction conditions on the yield of esterification were investigated. The optimum conditions were obtained as follows: methacrylic acid to neopentyl glycol molar ratio 2.1:1, dosage of sodium bisulfate = 7.5% of neopentyl glycol; cyclohexane dosage = 60% of neopentyl glycol; dosage of hydroquinone = 0.625% of neopentyl glycol; reaction temperature 110-115°; reflux and water segregating for 2.0 h. Neopentyl glycol dimethacrylate yield of over 94% was obtained under the optimum conditions. Sodium bisulfate exhibited higher catalytic activity, non-corrosiveness, non-pollution to the environment and repeated usability. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Computed Properties of 1985-51-9
