Khoom siv:
n-Butyric anhydride feem ntau yog siv los ua acylation reagent hauv organic synthesis. Nws tuaj yeem cuam tshuam nrog cawv, phenols, amines, thiab lwm yam los tsim cov esters, phenolic ethers, amides thiab lwm yam sib xyaw. Butyric anhydride tuaj yeem siv los ua cov khoom siv raw rau cov xim, dyes thiab plastics.
Cov ntaub ntawv kev nyab xeeb:
1.n-Butyric anhydride yog irritating thiab corrosive thiab tej zaum yuav ua rau khaus rau lub qhov muag, tawv nqaij, ua pa ib ntsuj av thiab digestive system.
2. Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag nrog daim tawv nqaij thiab qhov muag thiab xyuas kom meej tias kev ua haujlwm tau ua tiav nyob rau hauv qhov cua zoo.
3.Yog tias tsis muaj kev sib cuag nrog butyric anhydride, yaug tam sim ntawd nrog dej txaus thiab nrhiav kev pab kho mob.
4.Thaum khaws cia thiab thauj, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog oxidising agents thiab combustibles.
