Isopropanol

Isopropanol
CAS: 67-63-0
Ifomula yemichiza: C3H8O, butywala obunekhabhoni ezintathu. Ilungiswa nge-ethylene hydration reaction okanye ipropylene hydration reaction. Ayinambala kwaye ibonakale, kunye nevumba elimnandi kwiqondo lokushisa. Ineqondo eliphantsi lokubila kunye noxinaniso kwaye inyibilika lula emanzini, etywaleni nakwizinyibilikisi ze-ether. Yinto ebalulekileyo ephakathi kwi-synthesis yeekhemikhali kwaye ingasetyenziselwa ukudibanisa i-esters, i-ethers kunye ne-alcohol. Kwakhona kukhetho oluqhelekileyo kwishishini njenge-solvent kunye ne-arhente yokucoca, kwaye njengamafutha okanye i-solvent. Utywala be-Isopropyl bunobuthi obuthile, ngoko ke qaphela amanyathelo okukhusela xa usebenzisa, ugweme ukudibanisa nolusu kunye nokuphefumla.

Ngomhla we-14 kaNovemba, ixabiso lemarike yotywala ye-isopropyl yanamhlanje e-Shandong yaphakanyiswa, kwaye ixabiso lereferensi yemarike yayimalunga ne-7500-7600 yuan/ton. Ixabiso lemarike ye-acetone enyukayo liyekile ukuwa kwaye lizinzile, liqhuba ukuzithemba kwemarike yotywala ye-isopropyl. Imibuzo evela kumashishini asezantsi iye yanda, ukuthengwa kwempahla kuye kwaba bubulumko, kwaye iziko lemarike lomxhuzulane linyuke kancinci. Ngokubanzi, imarike yayisebenza ngakumbi. Kulindeleke ukuba imarike yotywala ye-isopropyl iya kuba namandla kakhulu kwixesha elifutshane.

Ngomhla we-15 kaNovemba, ixabiso le-benchmark ye-isopropyl alcohol kwindawo yoshishino yayiyi-7660.00 yuan / ton, eyehle ngo-5.80% xa kuthelekiswa nokuqala kwale nyanga (8132.00 yuan / ton).

Inkqubo yokuveliswa kotywala kwe-Isopropyl malunga ne-70% njengeyeza, i-pesticides, i-coatings kunye nezinye iindawo ze-solvents, ziyimathiriyeli ebalulekileyo yeekhemikhali, iindlela eziphambili zemveliso yindlela yepropylene kunye nendlela ye-acetone, inzuzo yangaphambili iyaqina, kodwa unikezelo lwasekhaya lulinganiselwe, kakhulu kwindlela ye-acetone. Ikuluhlu lweqela le-3 carcinogens ezichongwe nguMbutho wezeMpilo weHlabathi.
