Hauv kev lag luam tshuaj lom neeg loj heev, butyric anhydride yog ib qho "hnub qub" uas tsis tshua muaj zog tab sis muaj zog heev. Txawm hais tias nws tsis muaj xim thiab pob tshab, nws muaj peev xwm loj heev.
Butyric anhydride muaj qhov ceev ntawm 0.9668 (20/20 ℃), lub ntsiab lus yaj ntawm -75 ℃, thiab lub ntsiab lus kub ntawm 198 ℃. Nws cov yam ntxwv tshwj xeeb ua rau nws txawv ntawm ntau cov khoom siv tshuaj lom neeg. Nws yooj yim yaj hauv cov kuab tshuaj organic xws li ether. Thaum nws kov dej, nws lwj ua butyric acid, thiab thaum nws cuam tshuam nrog cawv, nws tsim cov esters. Cov yam ntxwv tshuaj lom neeg zoo kawg no qhib lub qhov rooj rau ntau yam kev siv.
Hauv kev tsim cov organic, butyric anhydride yog ib qho tseem ceeb uas tsis tuaj yeem tsis tau. Nws koom nrog kev tsim ntau yam tshuaj zoo, pab kev lag luam tshuaj hauv kev tsim cov tshuaj cawm siav thiab pab kev lag luam tshuaj tsw qab tsim cov ntxhiab tsw zoo. Nws kuj yog tus pab cuam muaj peev xwm hauv kev tsim cov yas thiab cov resins, txhim kho kev ua haujlwm ntawm cov khoom thiab ua rau peb lub neej muaj ntau yam ntxiv.
Kev xaiv butyric anhydride txhais tau tias xaiv cov khoom siv tshuaj lom neeg zoo thiab ua tau zoo. Peb tswj hwm cov txheej txheem tsim khoom kom ntseeg tau tias txhua tee ntawm butyric anhydride ua tau raws li cov qauv siab tshaj plaws, muab kev txhawb nqa ruaj khov thiab txhim khu kev qha rau koj cov khoom tsim tawm. Koom tes nrog peb thiab cia butyric anhydride ua lub zog txhawb nqa rau kev vam meej ntawm koj txoj kev lag luam!
