Awọn ohun-ini: ti ko ni awọ ati omi ti o han, amonia die-die.Ojutu yo 2.55 ℃, Oju-isun omi 210-212 ℃ (dibajẹ ni apakan ni 180 ℃), aaye Filaṣi154 ℃, Walẹ pato 1.1334 (20 ℃).Hygroscopic, miscible pẹlu omi ati ethanol, die-die tiotuka ni benzene, chloroform ati ether.
Nlo: ohun elo aise ti oogun Sintetiki, awọn turari, awọn awọ ati awọn miiran, tun bi epo fun yiyi awọn okun sintetiki, iṣelọpọ ṣiṣu, iṣelọpọ ti inki casein onigi.Tun lo bi awọn iwe processing oluranlowo, coagulant ti epo liluho ati ikole ile ise, carburizing nitriding oluranlowo ni Foundry ile ise, eranko lẹ pọ softener ati pola epo ti Organic kolaginni.
Iṣakojọpọ, Ibi ipamọ ati gbigbe: 220L ṣiṣu ilu tabi irin-ṣiṣu agba agba.Ideri yẹ ki o wa ni pipade lati yago fun jijo ati yago fun olubasọrọ pẹlu omi.Ti a fipamọ sinu itura, ibi gbigbẹ, kuro ninu ina ati ooru.
