Thiourea

Dibutyl thiourea yog dawb thiab ci siv lead ua, iab saj, ntom 1.41, melting point 176 ~ 178 degree, decomposition thaum kub, soluble nyob rau hauv dej, soluble nyob rau hauv ethanol thaum rhuab, heev me ntsis soluble nyob rau hauv ether.Lub sij hawm melting, nws ib nrab isomerizes rau daim ntawv. ammonium thiocyanide yog tsim los ntawm kev sib cuam tshuam ntawm hydrogen sulfide nrog txiv qaub slurry los tsim calcium hydrosulfide, thiab tom qab ntawd nrog calcium cyanamide (puag).

Chemical zog ntawm dibutyl thiourea:

Yooj yim deliquescent hauv huab cua. Hloov mus rau ammonium thiocyanate ntawm 150 degree. Sublimation ntawm 150-160 degree nyob rau hauv lub tshuab nqus tsev thiab decomposition ntawm 180 degree . Nws muaj qhov txo qis thiab tuaj yeem txo cov iodine dawb rau iodine ions. Cov khoom no yog heev reactive thiab yog siv los npaj ntau yam tebchaw. Nws tuaj yeem cuam tshuam nrog ntau yam oxidants los tsim urea, sulfuric acid, thiab lwm yam organic tebchaw, nrog rau yooj yim soluble ntxiv compounds nrog inorganic compounds.
