Triethylamine yog ib yam kua roj tsis muaj xim nrog ib qho tsw ntawm ammonia thiab muaj pa luam yeeb me ntsis hauv huab cua. Nws yaj me ntsis hauv dej, tab sis yaj hauv cov kuab tshuaj organic xws li ethanol thiab ether.

Triethylamine muaj ntau yam kev siv, feem ntau yog ua cov kuab tshuaj, tshuaj tiv thaiv, tshuaj tiv thaiv, thiab kuj siv tau rau hauv cov xim pleev xim. Tshwj xeeb:

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 lossis hloov cov kuab tshuaj no.

Tshuaj Tiv Thaiv thiab Tshuaj Tiv Thaiv: Hauv qee cov tshuaj tiv thaiv lossis cov txheej txheem khaws cia, triethylamine tuaj yeem ua lub luag haujlwm ntawm cov tshuaj tiv thaiv kom tiv thaiv kev sib xyaw ntawm cov tshuaj; tib lub sijhawm, nws kuj tseem siv tau ua cov tshuaj tiv thaiv kom ntev lub neej txee ntawm cov tshuaj.

Cov xim pleev xim: Triethylamine muaj daim ntawv thov tseem ceeb hauv kev tsim cov xim pleev xim thiab yog cov khoom siv tseem ceeb hauv cov txheej txheem tsim cov xim pleev xim.

Cov tshuaj catalyst yooj yim: Triethylamine feem ntau koom nrog ua cov tshuaj alkaline hauv cov tshuaj lom neeg, thiab nws cov txheej txheem catalytic cuam tshuam nrog cov kauj ruam xws li protonation, nucleophilic attack, thiab hydrogen bond tsim. Piv txwv li, triethylamine ua lub luag haujlwm tseem ceeb hauv catalytic hauv Swern oxidation, dehydrohalogenation, Heck reaction, thiab cov tshuaj tiv thaiv ntawm kev npaj esters thiab amides los ntawm acyl chlorides.

Daim ntawv thov hauv kev lag luam tshuaj:

Neutralizer: siv los kho cov khoom acid-base ntawm cov tshuaj thiab txhim kho kev ruaj khov thiab solubility ntawm cov tshuaj.

Catalyst: txhawb cov tshuaj tseem ceeb hauv cov txheej txheem ntawm kev tsim tshuaj thiab txhim kho kev ua haujlwm ntawm kev tsim tshuaj thiab cov txiaj ntsig ntawm cov tshuaj.

Cov tshuaj tiv thaiv pab pawg ua haujlwm: tiv thaiv cov pab pawg tshwj xeeb hauv cov tshuaj kom tiv thaiv lawv kom tsis txhob raug cuam tshuam los ntawm cov tshuaj tiv thaiv tsis tsim nyog lossis kev puas tsuaj thaum lub sijhawm tsim cov tshuaj.

Hauv kev xaus, triethylamine muaj ntau yam kev siv hauv ntau qhov chaw thiab yog cov khoom siv tshuaj lom neeg tseem ceeb.
