Thiourea Dawb Crystal Hmoov Rau Tshuaj, Tshuaj Fertilizer, Kub adsorption

Thiourea yog cov organic sulfur-muaj tshuaj, molecular mis CH4N2S, dawb thiab ci siv lead ua, iab saj, ntom 1.41g / cm, melting point 176 ~ 178ºC.Nws tawg thaum nws kub dua.Soluble hauv dej, soluble hauv ethanol thaum rhuab, me ntsis soluble hauv ether.Ib nrab isomerization yog ua thaum melting los tsim thiocyanurate tshwj xeeb ammonium.Nws kuj yog siv los ua vulcanization accelerator rau roj hmab thiab flotation tus neeg sawv cev rau hlau cov zaub mov, thiab lwm yam. Nws yog tsim los ntawm kev txiav txim ntawm hydrogen sulfide nrog txiv qaub slurry los tsim calcium sulphide, thiab tom qab ntawd nrog calcium cyanamide (paub pawg).Ammonium thiocyanate tuaj yeem raug fused los tsim, lossis cov cyanide thiab hydrogen sulfide ua los ntawm kev ua.
