Taw qhia

Trimethylamine yog ib hom organic compound. Nws yog ib qho tsis muaj xim tsis muaj roj nrog lub zog pungent tsw. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm trimethylamine:

Zoo:

Lub cev muaj zog: Trimethylamine yog cov roj tsis muaj xim, soluble hauv dej thiab cov kuab tshuaj organic, thiab tsim cov nplaim hluav taws sib xyaw nrog huab cua.

Chemical Properties: Trimethylamine yog nitrogen-carbon hybrid, uas kuj yog ib qho alkaline. Nws tuaj yeem hnov mob nrog cov kua qaub los tsim cov ntsev, thiab tuaj yeem hnov mob nrog qee cov carbonyl tebchaw los tsim cov khoom lag luam amination.

Siv:

Organic synthesis: Trimethylamine feem ntau yog siv los ua alkali catalyst hauv cov organic synthesis tshuaj. Nws tuaj yeem siv rau hauv kev npaj cov organic synthesis tshuaj xws li esters, amides, thiab amine compounds.

Txoj kev:

Trimethylamine tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm chloroform nrog ammonia nyob rau hauv lub xub ntiag ntawm alkali catalyst. Txoj kev npaj tshwj xeeb tuaj yeem yog:

CH3Cl + NH3 + NaOH → (CH3)3N + NaCl + H2O

Cov ntaub ntawv kev nyab xeeb:

Trimethylamine muaj cov ntxhiab tsw ntxhiab thiab raug rau qhov siab ntawm trimethylamine tuaj yeem ua rau qhov muag thiab ua pa ua pa.

Vim tias trimethylamine tsis muaj tshuaj lom, nws feem ntau tsis muaj kev phom sij rau tib neeg lub cev raws li kev siv tsim nyog thiab kev cia khoom.

Trimethylamine yog cov roj hluav taws kub, thiab nws cov sib tov muaj kev pheej hmoo ntawm kev tawg ntawm qhov kub thiab txias los yog qhib nplaim taws, thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua zoo kom tsis txhob sib cuag nrog cov nplaim taws qhib thiab qhov kub thiab txias.

Tiv tauj nrog oxidants, acids los yog lwm yam combustibles yuav tsum tau zam thaum lub sij hawm ua hauj lwm kom tsis txhob muaj teeb meem tshwm sim.

Yav dhau los: CAS Nr 111-65-9

Tom ntej: Azodicarbonamide (CAS # 123-77-3)
