三羟甲基丙烷（简称TMP），白色片状结晶。易溶于水、低碳醇、甘油、N,N-二甲基甲酰胺，部分溶于丙酮、乙酸乙酯，微溶于四氯化碳、乙醚和氯仿。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、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。

Trimethylolpropane (TMP), white flake crystal. Easily soluble in water, lower alcohol, glycerin, N, N-dimethylformamide, partially soluble in acetone and ethyl acetate, slightly soluble in carbon tetrachloride, ether and chloroform. It is mainly used in alkyd resin, polyurethane, unsaturated resin, polyester resin, coating and other fields. It can also be used to synthesize aviation lubricating oil, printing ink, etc. It can also be used as textile auxiliaries and heat stabilizer of PVC resin.

合成方法

synthetic method 

正丁醛与甲醛在碱性性条件下进行缩合反应，反应液经浓缩除盐，再用离子交换树脂脱色，提纯，后用薄膜蒸发器蒸发、冷却、轧片，得成品。

The condensation reaction of n-butyraldehyde and formaldehyde is carried out under alkaline conditions. The reaction solution is concentrated and desalted, then decolored and purified with ion exchange resin, and then evaporated, cooled and rolled with a film evaporator to obtain the finished product.

主要用途

Main purpose

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。

Trimethylolpropane is an important fine chemical product. It is a chain extender commonly used in the resin industry. It has a low melting point and three hydroxymethyl groups in its molecular structure. It can react with organic acids to form monoesters or polyesters, react with aldehydes and ketones to form acetals and ketals, and react with diisocyanates to form carbamates.

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。

The products are mainly used in alkyd resin, polyurethane, unsaturated resin, polyester resin, coating and other fields, and can also be used to synthesize aviation lubricating oil, plasticizer, surfactant, wetting agent, explosive, printing ink, etc., and can also be used as textile auxiliaries and thermal stabilizer of PVC resin.

应急处理

Emergency Management

隔离泄漏污染区，限制出入。切断火源。建议应急处理人员戴防尘面具，穿一般作业工作服。用砂土、干燥石灰或苏打灰混合。收集于干燥、洁净、有盖的容器中，转移场所。若大量泄漏，收集回收或运废物处理场所处置。

Isolate the contaminated area and restrict access. Cut off the ignition source. It is recommended that emergency personnel wear dust masks and general work clothes. Mix with sand, dry lime or soda ash. Collect in a dry, clean and covered container and transfer to a safe place. If there is a large amount of leakage, it shall be collected and recycled or transported to the waste treatment site for disposal.
