Ib tshuaj lom neeg nrog cov mis molecular CH3CH(OH)CH3. Lwm lub npe yog propan-2-ol, kev kho mob cawv. Cov kua muaj ntxhiab tsw muaj zog, yog nplaim taws, thiab tsis muaj xim.
Isopropyl cawv muaj ntau yam tshuaj lom neeg. Nws muaj peev xwm yaj hauv cawv, ether, chloroform, dej. Cov tshuaj no tsis cuam tshuam nrog ntsev. Vim tias cov cuab yeej ploj mus zoo hauv qhov chaw tsis muaj ntsev, isopropyl cawv yog ib qho yooj yim rau cais tawm hauv dej. Nws yog txaus kom ntxiv sodium sulfate los yog lub rooj ntsev zoo tib yam. Qhov no yog nws qhov txawv ntawm methanol thiab ethanol. Lub npe tsis raug rau txoj kev no yog "s alting". Siv nws cais isopropyl cawv rau hauv txheej.
Isopropyl cawv yog tsim nyob rau hauv peb txoj kev:
- Indirect hydration yog cov tshuaj tiv thaiv ntawm propylene nrog sulfuric acid. Qhov tshwm sim yog sib tov ntawm sulfate esters. Lawv kuj tau ua tiav thiab tau txais cov khoom tsim nyog. Cov khoom los ntawm cov khoom yog diisopropyl cawv.
- Direct hydration yog nqa tawm hauv cov kua lossis roj theem. Acid catalysts yuav tsum muaj. Propylene thiab dej yog reacted. Ob txheej txheem muaj nyob rau hauv kev sib cais ntawm isopropyl cawv los ntawmN2O.
- Hydrogenation ntawm acetone. Siv cov tshuaj acetone. Nws yog hydrogenated siv tooj liab thiab chromium oxides los yog siv Raney nickel.
Isopropyl cawv yog siv dav. Feem ntau nws yog siv nyob rau hauv pharmaceuticals. Hauv kev lag luam, nws yog siv los ua cov kuab tshuaj. Hauv kev lag luam tshuaj, nws yog siv los tsim cumene. Raws li cov txiaj ntsig ntawm xyoo tas los, isopropyl cawv feem ntau siv hauv tshuaj pleev ib ce thiab hauv lub neej txhua hnub. Cov khoom no yog siv los ua ib qho ntxiv hauv roj av.
cawv no yog siv tshuaj los ua tshuaj tua kab mob. Lawv raug kho nrog qhov chaw txhaj tshuaj. Nws kuj tseem siv los ua tshuaj tua kab mob. Feem ntau siv los ua desiccant rau otitis externa.
Isopropyl cawv kiag li txawv ntawm qhov kev ua kom huv si ib txwm muaj. Nws muaj qhov tsawg kawg nkaus ntawm impurities. Nws dissolves resins thiab roj zoo, tsis ua mob rau cov xim pleev xim. Vim li no, nws tau dhau los ua dav hauv kev lag luam automotive. Nws feem ntau tau ntxiv rau iav ntxuav.
Hauv chav kuaj, isopropyl cawv yog siv los ua cov khoom noj khoom haus lom neeg. Siv nws rau cov organic. Nws yog lwm txoj hauv kev zoo rau cov khoom siv hluavtaws xws li formaldehyde.
Qhov twg yuav isopropyl cawv? Hauv cov khw muag khoom lag luam wholesale. Nws feem ntau yog muag hauv ntau qhov ntau. Txawm hais tias nws siv dav, nws tuaj yeem ua raulom. Yog li ntawd, txhua qhov kev ceev faj yuav tsum tau ua thaum siv tshuaj tiv thaiv kab mob, tshuaj ntxuav iav, tshuaj pleev thaiv hnub, thiab lwm yam.
Qhov peculiarity ntawm isopropyl cawv yog tias nws tsis nkag mus rau hauv lub cev los ntawm daim tawv nqaij. Tab sis ntawm qhov tod tes, nws zoo kawg nkaus absorbed los ntawm lub ntsws thiab lub plab. Nws muaj kev nyuaj siab rau lub hauv nruab nrab lub paj hlwb 2 lub sij hawm muaj zog tshaj ethanol. Hauv daim siab, nws tau ua tiav rau hauv acetone, thiab tom qab ntawd tawm los ntawm cov zis. Kev kho mob muaj gastric lavage. Yog tias lub cev qhuav dej lossis poob siab tshwm sim, kev kho mob nrog sodium bicarbonate yog nqa tawm. Hemodialysis qhia nws tus kheej zoo.
