Isopropanol
CAS: 67-63-0
Fomula ya mankhwala: C3H8O, ndi mowa wa kaboni atatu. Umapangidwa ndi ethylene hydration reaction kapena propylene hydration reaction. Wopanda utoto komanso wowonekera bwino, wokhala ndi fungo lopweteka kutentha kwa chipinda. Uli ndi kutentha kochepa komanso kuchuluka kwake ndipo umasungunuka mosavuta m'madzi, mowa ndi ether solvents. Ndi chinthu chofunikira kwambiri popanga mankhwala ndipo chingagwiritsidwe ntchito popanga ma esters, ethers ndi alcohols. Ndi chinthu chodziwika bwino m'mafakitale monga solvent ndi chotsukira, komanso ngati mafuta kapena solvent. Isopropyl alcohol ili ndi poizoni winawake, choncho samalani ndi njira zodzitetezera mukamagwiritsa ntchito, pewani kukhudzana ndi khungu ndi kupuma.

Pa Novembala 14, mtengo wa msika wa mowa wa isopropyl lero ku Shandong unakwezedwa, ndipo mtengo wofunikira pamsika unali pafupifupi 7500-7600 yuan/tani. Mtengo wa msika wa acetone wokwera unasiya kutsika ndipo unakhazikika, zomwe zinapangitsa kuti msika wa mowa wa isopropyl ukhale wolimba. Mafunso ochokera kumakampani otsika mtengo anawonjezeka, kugula kunali kosamala, ndipo malo ofunikira pamsika anawonjezeka pang'ono. Ponseponse, msika unali wotanganidwa kwambiri. Zikuyembekezeka kuti msika wa mowa wa isopropyl udzakhala wolimba kwambiri posachedwa.

Pa Novembala 15, mtengo woyerekeza wa mowa wa isopropyl m'gulu la amalonda unali 7660.00 yuan/tani, womwe unatsika ndi -5.80% poyerekeza ndi kumayambiriro kwa mwezi uno (8132.00 yuan/tani).

Njira yopangira mowa wa Isopropyl pafupifupi 70% monga mankhwala, mankhwala ophera tizilombo, zokutira ndi zina zosungunulira, ndi mankhwala ofunikira kwambiri, njira zazikulu zopangira ndi njira ya propylene ndi njira ya acetone, phindu lakale ndi lalikulu, koma kupezeka kwapakhomo kuli kochepa, makamaka njira ya acetone. Ili pamndandanda wa zinthu zomwe zimayambitsa khansa za Gulu 3 zomwe zadziwika ndi World Health Organisation.
