Cov khoom lag luam
Cov tshuaj nrog tus lej cas 108-30-5 yog succinic anhydride, tseem hu ua diydro {}}} furandione. Nws molecular mis yog c₄h₄o₃ thiab nws cov molecular hnyav yog 100.07.
Nyob rau ntawm chav tsev kub, succinic anhydride tshwm sim ua tus tsis muaj kob ntxawg-puab lossis cov siv lead ua. Nws muaj cov ntxhiab tsw ntxhiab tsw ntxhiab, lub ntsiab lus melting ntawm {1}} degree ntawm 261 degree ntawm 1.572g / thiab ib sublimation taw tes ntawm 90 degree. Nws yog me ntsis soluble hauv dej thiab ether, tab sis soluble hauv chloroform, carbon tetrachloride, thiab ethanol. Thaum raug rau dej kub, nws hydrolyzes rau hauv succinic acid. Nws yog reactive thiab tuaj yeem txuas ntxiv ntxiv, hws, thiab lwm yam kev tawm tsam nrog ntau yam sib xyaw. Ib qho ntxiv, nws yog acidic thiab tuaj yeem hnov mob nrog alkalis los ua cov ntsev ua yeeb yam.
