Thiourea
Kumenyekanisha ibicuruzwa
Thiourea ni ifumbire ya sulfure kama, formula ya chimique CH4N2S, kirisiti yera nuburabyo, uburyohe bukaze, ubucucike 1.41g / cm³, gushonga 176 ~ 178 ℃. Ikoreshwa mugukora ibiyobyabwenge, amarangi, ibisigazwa, ifu yububiko nibindi bikoresho fatizo, byanakoreshwa nka moteri yihuta ya reberi, ibyuma byangiza ibyuma nibindi. Ikorwa nigikorwa cya hydrogen sulfide hamwe na lime slurry kugirango ikore calcium hydrosulfide hanyuma calcium cyanamide. Irashobora kandi gutegurwa mugushonga amonium thiocyanide, cyangwa mugukora cyanamide hamwe na hydrogen sulfide.
Ironderero rya tekiniki
Ikoreshwa
Thiourea ikoreshwa cyane nkibikoresho fatizo byo guhuza sulfathiazole, methionine n’ibindi biyobyabwenge, kandi birashobora no gukoreshwa nkibikoresho fatizo byo gusiga amarangi no gufasha amarangi, resin hamwe nifu ya poro, kandi birashobora no gukoreshwa nkumuvuduko wihuta wibikoresho bya reberi. , flotation agent kumyunyu ngugu, umusemburo wo gukora anhydride ya phthalic na aside fumaric, kandi nkicyuma cyangiza ingese. Kubijyanye nibikoresho bifotora, birashobora gukoreshwa nkuwiteza imbere na toner, kandi birashobora no gukoreshwa muruganda rukora amashanyarazi. Thiourea ikoreshwa kandi mu mpapuro zifotora za diazo, impuzu ya sintetike ya resinike, amavuta yo guhanahana anion, abamamaza imbuto, fungiside nibindi byinshi. Thiourea nayo ikoreshwa nk'ifumbire. Ikoreshwa mugukora ibiyobyabwenge, amarangi, ibisigarira, ifu yububiko, umuvuduko wa reberi wihuta, ibikoresho bya minerval flotation nibindi bikoresho fatizo.
