用途 Description

三羟甲基丙烷是一种重要的精细化工产品,它是树脂行业常用的扩链剂。其熔点低,分子结构中有3个羟甲基,可与有机酸反应生成单酯或多酯,与醛、酮反应生成缩醛、缩酮,与二异氰酸酯反应生成氨基甲酸酯等。

产品主要用于醇酸树脂、聚氨酯、不饱和树脂、聚酯树脂、涂料等领域,也可用于合成航空润滑油、增塑剂、表面活性剂、润湿剂、炸药、印刷油墨等,还可用作纺织助剂和聚氯乙烯树脂的热稳定剂。

TMP is mainly consumed as a precursor to alkyd resins. Otherwise, acrylated and alkoxylated TMP's are used as multifunctional monomers to produce various coatings, ethoxylated and propoxylated TMP, derived condensation of from TMP and the epoxides, are used for production of flexible polyurethanes. Allyl ether derivatives of TMP, with the formula CH3CH2C(CH2OCH2CH=CH2)3-x(CH2OH)xare precursors to high-gloss coatings and ion exchange resins. The oxetane "TMPO" is a photoinduceable polymerization initiator.[1]
