Cov morphology thiab cov khoom yooj yim ntawm N,N-dimethylbenzylamine

Cov Lus Qhia: N,N-dimethylbenzylamine yog xim tsis muaj xim rau daj daj kua pob tshab.

Tsw: Muaj ntxhiab tsw ntawm ammonia.

Kev yaj: Miscible nrog cawv thiab ether, soluble hauv dej kub, me ntsis soluble hauv dej txias.

Kev Huv thiab Dej: Nws qhov kev huv feem ntau yog ≥98% lossis siab dua, xws li 99%, 99.5%, thiab cov dej noo yog ≤0.05% lossis ≤0.2%.

Lwm yam khoom siv lub cev: Lub ntsiab lus yaj yog li -75 ° C, lub ntsiab lus kub yog 183-184 ° C (lossis 178-184 ° C, 178-181 ° C, thiab lwm yam), qhov ceev yog li 0.9 g / mL, thiab qhov ntsuas refractive yog li 1.501 (lossis 1.495-1.503).

N,N-dimethylbenzylamine siv dav hauv kev lag luam tshuaj lom neeg. Nws feem ntau siv ua tus catalyst, corrosion inhibitor, thiab neutralizer. Nws kuj siv rau hauv kev tsim cov organic, xws li ua tus neeg sawv cev rau epoxy resin thiab kev tsim cov ntsev quaternary ammonium. Thaum khaws cia thiab thauj mus los, yuav tsum ua raws li cov cai rau cov tshuaj lom neeg corrosive kom ntseeg tau tias muaj kev nyab xeeb.

N,N-dimethylbenzylamine (BDMA) yog ib qho khoom siv ntau yam organic uas siv dav hauv ntau qhov chaw.

Kev Lag Luam Polyurethane: Ua ib qho catalyst rau polyester polyurethane thaiv ua npuas ncauj mos, ua npuas ncauj tawv thiab cov nplaum txheej, nws feem ntau yog siv rau ua npuas ncauj tawv. Nws tuaj yeem txhim kho qhov fluidity thaum ntxov thiab cell uniformity ntawm polyurethane ua npuas ncauj, thiab txhim kho cov ua npuas ncauj thiab lub hauv paus. Cov khoom siv lo rau.
Epoxy resin teb: Ua ib qho accelerator rau acid anhydride, nws yog siv los npaj cov txheej txheem impregnated epoxy resin tsis muaj kuab tshuaj. Nws txhawb nqa acid anhydride kho bisphenol A epoxy resin thiab siv dav hauv cov ntaub ntawv hluav taws xob potting, cov ntaub ntawv encapsulation, thiab lwm yam.
Kev tsim cov organic: Siv ua tus catalyst dehydrohalogenation thiab tus neeg sawv cev neutralizing acid rau kev tsim cov tshuaj organic. Nws kuj tseem siv los tsim cov ntsev quaternary ammonium thiab tsim cov tshuaj tua kab mob cationic surfactant muaj zog, thiab lwm yam.

Ntxiv rau, N, N-dimethylbenzylamine kuj tseem siv tau ua cov tshuaj dehydrogenation, tshuaj preservative, thiab lwm yam. Thaum lub sijhawm khaws cia thiab thauj mus los, yuav tsum ua raws li cov kev cai rau cov tshuaj lom neeg corrosive kom ntseeg tau tias muaj kev nyab xeeb.
