Txheej txheem cej luam:

Triethylamine (cov mis molecular: C6H15N), tseem hu ua N,N-diethylethylamine, yog qhov yooj yim tshaj plaws homo-trisubstituted tertiary amine thiab muaj cov khoom zoo li tertiary amines, suav nrog kev tsim ntsev, oxidation, thiab Hingsburg cov khoom ntawm triethylamine. Kev sim (Hisbergreaction) tsis muaj lus teb. Nws zoo li tsis muaj xim rau lub teeb daj pob tshab kua nrog lub zog ammonia tsw. Chemicalbook haus luam yeeb me ntsis hauv huab cua. Boiling point: 89.5 ℃, qhov ceev sib piv (dej = 1): 0.70, qhov ceev sib piv (cua = 1): 3.48, me ntsis soluble hauv dej, soluble hauv ethanol thiab ether. Aqueous cov kua yog alkaline. Nws yog flammable, thiab nws cov pa tuaj yeem tsim cov khoom sib xyaw nrog huab cua, nrog rau qhov txwv tawg ntawm 1.2% txog 8.0%. Tshuaj lom, khaus heev.

Txoj kev npaj no tuaj yeem tau los ntawm kev sib xyaw tshuaj ethanol thiab ammonia nyob rau hauv qhov muaj hydrogen hauv lub reactor uas muaj cov catalyst tooj liab-nickel-av nplaum nyob rau hauv qhov kub thiab txias (190 ± 2 ° C thiab 165 ± 2 ° C). Cov tshuaj tiv thaiv kuj tseem yuav tsim cov monoethylamine thiab diethylamine. Tom qab condensation, cov khoom raug txau nrog ethanol thiab nqus kom tau txais cov triethylamine nyoos. Thaum kawg, tom qab sib cais, dehydration thiab fractionation, cov triethylamine ntshiab tau txais.

Triethylamine siv tau ua cov kuab tshuaj thiab cov khoom siv raw hauv kev lag luam organic synthesis. Nws siv tau ua catalyst rau kev npaj phosgene polycarbonate, tetrafluoroethylene inhibitor polymerization, roj hmab vulcanization accelerator, cov kuab tshuaj tshwj xeeb hauv cov xim tshem tawm, enamel anti-hardening agent, surfactant, preservative, bactericide, Ion exchange resins, dyes, spices, tshuaj, roj zog siab thiab kua rocket propellants, thiab lwm yam.
