Taw qhia
Ib qho allyl trifluoroacetate (allyl trifluoroacetate) yog cov organic compound nrog cov tshuaj formula C5H7F3O2. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
- allyl trifluoroacetate yog cov kua tsis muaj xim uas muaj ntxhiab tsw.
-Nws qhov kub kub yog li 68 ° C, thiab qhov ceev yog li 1.275 g / mL.
-Nws yog soluble nyob rau hauv ntau yam organic solvents, xws li ethers thiab cawv.
Siv:
- allyl trifluoroacetate yog dav siv los ua hluavtaws intermediates hauv cov organic synthesis thiab tuaj yeem siv los ua ke ntau yam ntawm cov organic sib txuas.
-Nws tuaj yeem siv los ua tus neeg sawv cev sib txuas rau cov khoom siv polymers thiab siv los npaj cov ntaub ntawv polymer, xws li txheej thiab yas.
-Vim nws tsis tshua muaj combustion kub, nws kuj yuav siv tau raws li ib tug additive rau roj.
Txoj Kev Npaj:
allyl trifluoroacetate tuaj yeem ua ke los ntawm kev hloov pauv ntawm trifluoroacetic acid thiab allyl cawv. Cov kev mob tshwm sim tuaj yeem ua kom sov siv cov catalyst xws li lub hauv paus lossis acid catalyst.
Cov ntaub ntawv kev nyab xeeb:
- allyl trifluoroacetate ua rau khaus thiab tuaj yeem ua rau lub qhov muag, tawv nqaij thiab ua pa puas.
- Hnav tsom iav, hnab looj tes thiab tiv thaiv ua pa thaum siv lossis ua haujlwm.
-Thaum ntsib daim tawv nqaij lossis qhov muag, yaug tam sim nrog dej kom ntau thiab nrhiav kev pab kho mob.
-Thaum khaws cia thiab siv, tsis txhob sib cuag nrog oxidants, acids thiab alkalis, thaum ua kom deb ntawm hluav taws kub thiab kub ib puag ncig.
Thov nco ntsoov tias allyl trifluoroacetate yog ib qho tshuaj thiab yuav tsum tau siv raws li cov txheej txheem kev nyab xeeb hauv chav kuaj kom raug thiab khaws cia, tuav thiab pov tseg raws li cov kev cai cuam tshuam.
