Khoom Description
N - Butyl Cyanacetate, tseem hu ua Butyl Cyanacetate. Nws cov roj molecular yog c7h11NO2, nrog lub cev hnyav li qub ntawm 141.1677, tus lej ntawm {}}} {7}}.
Nws nthuav tawm raws li cov kua dej tsis muaj xim lossis lub teeb daj-daj pob tshab. Nws yog insoluble hauv dej tab sis miscible nrog cov kuab tshuaj organic xws li ethanol. Nyob rau hauv ib txwm kub thiab siab, nws tseem ruaj khov. Txawm li cas los xij, nws tuaj yeem kub hnyiab tau thaum raug hluav taws kub thiab tsim cov pa roj carbon monoxide lom heev thaum raug kub los yog sib cuag nrog cov kua qaub. Nws tuaj yeem hnov mob nrog cov oxidants muaj zog thiab hnov mob nrog dej lossis dej vapor kom tso tawm cov pa phem thiab nplaim taws.
