Butyric anhydride / CAS: 106-31-0

Kev siv

Buteryric anhydride yog tsuas yog siv los ua ib qho tshuaj realating hauv cov suab hluav taws xob hauv nruab nrog cev. Nws tuaj yeem ua rau muaj cawv, phenols, amines, thiab lwm yam los ua cov ntawv sib raug zoo, cov lus sib piv, nyob rau lwm cov chaw sib txuas. Buteryric anhydride kuj tseem siv tau ua cov khoom siv raw rau txheej txheej, zas thiab plastics. Buteryric anhydride tuaj yeem npaj los ntawm reacting butyric acid nrog acetic anhydride. Cov tshuaj tiv thaiv feem ntau tau nqa tawm hauv qab cov duab acidic thiab ntawm cov kub tsawg. Buteryric anthydride yog khaus thiab corrosive thiab tej zaum yuav ua rau kev npau taws rau lub qhov muag, tawv nqaij, ua pa tawm thiab lub plab zom mov. Thaum lub sijhawm ua haujlwm, kev saib xyuas yuav tsum tau noj kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab ua kom cov haujlwm tau ua tiav lawm - ventilated tej yam kev mob.

Nws yog cov kua tsis muaj kob thiab pob tshab nrog cov tsis hnov ​​tsw. Cov txheeb ze ceev yog 0.9668 (20/20 ℃), lub ntsiab lus melting yog -75 ℃, thiab lub boiling point yog 198 ℃. Nws yog soluble hauv cov kuab tshuaj muaj kuab tshuaj xws li Etaws. Nws decomposes rau hauv butyric acid thaum ntsib dej. Nws cuam tshuam nrog dej cawv rau cov ntawv esters. Nws yog ib qho tsis muaj kob, pob tshab thiab kua roj. Nws yog soluble hauv dej thiab decomposes los ua butyric acid, thiab nws yog soluble hauv ether.
