Guryahadareere aan midab lahayn oo hufan, wax yar ammonia.Dhibicda dhalaalaysa 2.55 ℃, barta karkarinta 210-212 ℃ (qayb qudhuntay 180 ℃), Flash point154 ℃, Cuf-jiid gaar ah 1.1334 (20 ℃).Hygroscopic, oo lagu khaldi karo biyo iyo ethanol, wax yar ku milmay benzene, chloroform iyo ether.
Waxay isticmaashaa: alaabta ceeriin ee daawada synthetic, dhir udgoon, midabyo iyo kuwa kale, sidoo kale sida dareere loogu talagalay miiqinta fiilooyinka synthetic, farsamaynta caagga ah, soo saarista khad casein alwaax ah.Waxa kale oo loo isticmaalaa sida wakiilka warshadaynta warqad, coagulant of qodista saliidda iyo warshadaha dhismaha, carburizing wakiilka nitriding in industry foundry, jilciye xabagta xayawaanka iyo millataye polar ee synthesis organic.
Baakadaha, Kaydinta iyo gaadiidka: 220L durbaan caag ah ama foosto ka samaysan bir-cag.Daboolka waa in la xiraa si looga hortago in ay daadato lagana fogaado taabashada biyaha.Lagu kaydiyaa meel qabow oo qallalan, kana fog dabka iyo kulaylka.
