Iipropati zeKhemikhali

Ulwelo oluvutha ngaphandle kombala, olucacileyo okanye olutyheli olukhanyayo. Kukho ivumba elinamandla elirhabaxa. Luxutywa ne-ethanol (ukubola), i-diethylene glycol, i-ether, i-acetone, i-carbon tetrachloride, i-benzene, i-chlorobenzene, i-kerosene, kunye neoyile yomnquma.

Sebenzisa:

Isetyenziswa njengezinto zokwenza izinto zokwenza i-polyurethane foam eguquguqukayo, ii-coating, irabha kunye ne-adhesives

Indlela yemveliso

1. Ilungiswa ngempendulo ye-2,4-diaminotoluene kunye ne-phosgene. Okokuqala, nyibilikisa i-diaminotoluene eqinileyo kwi-benzene ekhlorini, uze uyifudumeze ukuya kuma-70°C ngokuyixuba ukuze ufumane isisombululo se-diaminotoluene chlorobenzene. I-phosgenated benzene oxide efunyenweyo ifakwa kwimbiza ye-phosgene enobushushu obuphantsi kwaye kongezwa isixa esithile sokukhanya kolwelo. Emva kokufaka igesi, yongeza isisombululo se-diaminotoluene esilungisiweyo ngokuhla ngelixa uxuba iChemicalbook, yenza i-phosgenation kuma-40°C, uze ufake izinto ze-phosgenation ezinobushushu obuphantsi kwimbiza enobushushu obuphezulu ukuze i-phosgenation ibe nobushushu obuphezulu, uze uyiphefumle ngelixa ifudumeza, malunga neeyure ezi-4, impendulo ngokubanzi yenziwa kwi-120~125℃; emva kokuba impendulo igqityiwe, ifunyanwa ngokuyixuba nge-nitrogen, ukuyihluza, kunye nokulungisa.
