Isopropanol

Isopropanol
CAS: 67-63-0
Ifomula yamakhemikhali: C3H8O, utshwala obunamakhabhoni amathathu. Ilungiswa nge-ethylene hydration reaction noma i-propylene hydration reaction. Ayinambala futhi isobala, enephunga elimnandi ekamelweni lokushisa. Inephuzu eliphansi lokubilisa kanye nokuminyana futhi incibilika kalula emanzini, otshwaleni nasezincibilikisini ze-ether. Iyingxenye ebalulekile yokuhlanganiswa kwamakhemikhali futhi ingasetshenziswa ukwenza ama-ester, ama-ether nama-alcohol. Futhi kuwukukhetha okuvamile embonini njenge-solvent kanye ne-ejenti yokuhlanza, nanjengamafutha noma isincibilikisi. I-Isopropyl alcohol inobuthi obuthile, ngakho-ke qaphela izinyathelo zokuzivikela lapho usebenzisa, gwema ukuthintana nesikhumba nokuhogela.

Ngomhla ziyi-14 kuNovemba, intengo yemakethe yotshwala ye-isopropyl yanamuhla eShandong yaphakanyiswa, futhi intengo yereferensi yemakethe yayilinganiselwa ku-7500-7600 yuan/ton. Intengo yemakethe ye-acetone ekhuphukayo iyeke ukwehla futhi yazinza, yaqhuba ukuzethemba kwemakethe yotshwala ye-isopropyl. Imibuzo evela emabhizinisini angezansi inyukile, ukuthengwa kwezimpahla bekucophelela, futhi isikhungo semakethe sokudonsela phansi sikhuphuke kancane. Sekukonke, imakethe ibisebenza kakhulu. Kulindeleke ukuthi imakethe yotshwala ye-isopropyl ibe namandla kakhulu esikhathini esifushane.

Ngomhlaka-15 Novemba, intengo yokuma yotshwala be-isopropyl emphakathini webhizinisi yayingu-7660.00 yuan/ton, eyehle ngo--5.80% uma kuqhathaniswa nokuqala kwale nyanga (8132.00 yuan/ton).

Inqubo yokukhiqiza utshwala ye-Isopropyl cishe ngama-70% njengomuthi, izibulala-zinambuzane, okokugqoka kanye nezinye izithako ezincibilikisayo, iyizinto ezisetshenziswayo zamakhemikhali ezibalulekile, izindlela zokukhiqiza eziyinhloko yindlela ye-propylene nendlela ye-acetone, inzuzo yangaphambili ishubile, kepha ukunikezwa kwasekhaya kunqunyelwe, ikakhulukazi indlela ye-acetone. Isohlwini lwama-carcinogens eQembu 3 ahlonzwe yi-World Health Organization.
