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 

正丁醛與甲醛在堿性性條件下進行縮合反應，反應液經濃縮除鹽，再用離子交換樹脂脫色，提純，后用薄膜蒸發器蒸發、冷卻、軋片，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

三羥甲基丙烷是一種重要的精細化工產品，它是樹脂行業常用的擴鏈劑。其熔點低，分子結構中有3個羥甲基，可與有機酸反應生成單酯或多酯，與醛、酮反應生成縮醛、縮酮，與二異氰酸酯反應生成氨基甲酸酯等。

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.

產品主要用于醇酸樹脂、聚氨酯、不飽和樹脂、聚酯樹脂、涂料等領域，也可用于合成航空潤滑油、增塑劑、表面活性劑、潤濕劑、炸藥、印刷油墨等，還可用作紡織助劑和聚氯乙烯樹脂的熱穩定劑。

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.

應急處理

Emergency Management

隔離泄漏污染區，限制出入。切斷火源。建議應急處理人員戴防塵面具，穿一般作業工作服。用砂土、干燥石灰或蘇打灰混合。收集于干燥、潔凈、有蓋的容器中，轉移場所。若大量泄漏，收集回收或運廢物處理場所處置。

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.
