合成方法

synthetic method 

正丁醛與甲醛在堿性性條件下進(jìn)行縮合反應(yīng)，反應(yīng)液經(jīng)濃縮除鹽，再用離子交換樹(shù)脂脫色，提純，后用薄膜蒸發(fā)器蒸發(fā)、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(xì)化工產(chǎn)品，它是樹(shù)脂行業(yè)常用的擴(kuò)鏈劑。其熔點(diǎn)低，分子結(jié)構(gòu)中有3個(gè)羥甲基，可與有機(jī)酸反應(yīng)生成單酯或多酯，與醛、酮反應(yīng)生成縮醛、縮酮，與二異氰酸酯反應(yīng)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(chǎn)品主要用于醇酸樹(shù)脂、聚氨酯、不飽和樹(shù)脂、聚酯樹(shù)脂、涂料等領(lǐng)域，也可用于合成航空潤(rùn)滑油、增塑劑、表面活性劑、潤(rùn)濕劑、炸藥、印刷油墨等，還可用作紡織助劑和聚氯乙烯樹(shù)脂的熱穩(wěn)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(yīng)急處理

Emergency Management

隔離泄漏污染區(qū)，限制出入。切斷火源。建議應(yīng)急處理人員戴防塵面具，穿一般作業(yè)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(zhuǎn)移場(chǎng)所。若大量泄漏，收集回收或運(yùn)廢物處理場(chǎng)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.
