Triethylamine yog cov kua roj tsis muaj xim nrog rau ntxhiab ammonia lossis ntxhiab ntses, zoo ib yam li ntxhiab dej ammonia, thiab muaj pa me ntsis hauv huab cua.

Tshwj xeeb, triethylamine tshwm sim ua kua tsis muaj xim rau lub teeb daj pob tshab, me ntsis soluble hauv dej, tab sis soluble hauv cov organic solvents xws li ethanol thiab ether. Nws cov mis tshuaj yog C6H15N, boiling point yog li 89.5 ℃, density yog li 0.73, flash point yog -7 ℃, thiab molecular hnyav yog 101.196. Cov khoom siv lub cev no ua ke txiav txim siab cov kua ntawm triethylamine ntawm chav tsev kub thiab siab.

Triethylamine muaj ntau yam kev siv. Nws feem ntau yog siv ua cov kuab tshuaj, inhibitor, preservative, thiab kuj tseem siv tau los ua cov xim dyes, ua alkaline catalyst, thiab kho pH.

Hauv kev nthuav dav, triethylamine muaj cov ntawv thov tseem ceeb hauv cov teb hauv qab no:

Cov kuab tshuaj: Triethylamine yaj tau hauv feem ntau cov kuab tshuaj organic xws li ethanol, ether, thiab acetone, yog li nws feem ntau siv los ua ib feem ntawm cov kuab tshuaj no los pab yaj thiab tawg lwm yam tshuaj.

Cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv: Hauv kev lag luam, triethylamine yog siv los ua cov tshuaj tiv thaiv kom tiv thaiv kev tsim cov polymers thaum lub sijhawm qee yam tshuaj lom neeg. Tib lub sijhawm, nws kuj muaj cov nyhuv antiseptic thiab tuaj yeem ntev lub sijhawm txee ntawm cov tshuaj.

Cov xim pleev ua los ntawm cov khoom siv hluavtaws: Triethylamine siv tau los ua cov xim pleev kom pab cov xim pleev kom tawg thiab pleev zoo dua.

Alkaline catalyst: Triethylamine yog ib qho organic base uas tuaj yeem tsim cov ntsev soluble nrog inorganic acids. Hauv kev tsim tshuaj lom neeg, nws feem ntau siv los ua alkaline catalyst los catalyze cov tshuaj tiv thaiv xws li esterification, acylation thiab olefination.

Kho pH: Vim tias triethylamine tuaj yeem ua rau cov kua qaub ua rau cov ntsev, nws tuaj yeem siv los ua kom cov tshuaj acidic tsis muaj zog thiab hloov pauv qhov sib npaug ntawm cov kua qaub-puag ntawm qhov chaw ib puag ncig, uas yog qhov tseem ceeb heev hauv kev tsim cov organic sib xyaw.

Tsis tas li ntawd xwb, triethylamine kuj tseem siv tau ua roj muaj zog heev, roj hmab vulcanization accelerator, surfactant, wetting agent thiab bactericide, thiab lwm yam.

Txawm li cas los xij, txawm hais tias triethylamine siv dav hauv ntau qhov chaw, nws kuj muaj qee yam tshuaj lom thiab khaus. Yog li ntawd, nws yog qhov tsim nyog yuav tsum ua raws li cov txheej txheem kev nyab xeeb thaum siv kom ntseeg tau tias muaj kev nyab xeeb ntawm tib neeg thiab ib puag ncig.
