2, 2-Dimethylolpropionic acid is an intermediate for dyes and pesticides. It can be used to synthesize a series of esters and metal salts of DMPA and also be used to synthesize hindered phenolic antioxidants. DMPA can join polycondensation reaction as a dihydric alcohol. 2,2-二羟甲基丙酸(DMPA)是染料及农药的中间体,还可以制成一系列的DMPA的酯类和金属盐类,也可用来合成受阻酚类抗氧剂,DMPA作为一种二元醇可以参加缩聚反应。
The results indicated that Mo-PF was synthesized by esterified reaction between molybdic acid and hydroxymethyl in phenolic alcohol, in this reaction, the transition metal Mo atom was bonded in the major molecule chains of PF. 结果表明:钼酚醛树脂是通过钼酸与酚醇中的羟甲基发生酯化反应,使钼以化学键的形式键合于酚醛树脂分子主链中而合成的;
In this paper, simultaneous γ-ray radiation graft copolymerization was used to improve surface property of carbon fibers ( CF) with phenolic aldehyde/ ethyl alcohol solutions of different concentrations. 本文利用γ射线共辐照接枝技术,在酚醛/乙醇溶液中对碳纤维表面进行处理。
A new type of phenolic resin adhesive for casting was prepared by condensation polymerization of furfuryl alcohol and the reaction product between phenol, phenylphenol, urea and formaldehyde. 苯酚、苯基苯酚、尿素与甲醛的反应产物进一步与糖醇缩聚生成新型铸造用改性酚醛树脂粘结剂。
