Propyl cawv muaj ntau yam kev siv. Nws yog ib qho hnyav hnyav rau alkaloids, ntau cov roj yam tseem ceeb, qee cov khoom siv hluavtaws, thiab lwm yam.
Qhov nrov ntawm isopropyl cawv yog vim qhov tseeb tias feem ntau cov organic tshuaj (esters, roj, waxes, lipids, thiab lwm yam) yaj zoo hauv cov kua no. Hauv kev lag luam, isopropanol tau txais los ntawm kev tso dej ncaj qha ntawm propylene. Lub ntsiab raw khoom rau kev sib txuas ntawm isopropanol yog propylene feem ntawm cov roj pyrolysis gases thiab cov propane-propylene feem ntawm cov roj tawg gases.
Propyl cawv yog siv rau hauv kev luam ntawv, roj, tshuaj, kev kho mob, zaub mov, rooj tog, naj hoom thiab ntoo tshuaj industries.
Hauv kev lag luam luam ntawv, isopropanol yog siv hauv cov txheej txheem luam ntawv kom moisten. Propyl cawv yog cov khoom siv tseem ceeb rau kev tsim cov acetone, isopropyl ethanoate, thiab lwm yam esters. Kev tsim cov yas niaj hnub tseem yuav tsum tau siv cov isopropanol.
Propyl cawv yog siv rauntxuav polypropylene. Kev lag luam xim thiab cov kua roj vanish siv cov khoom no ua cov kuab tshuaj ntawm ethyl-, acetyl- thiab nitrocellulose. Isopropanol yog ib qho tseem ceeb tshaj plaws co-solvents nyob rau hauv zus tau tej cov nitro-varnishes. Cov tshuaj no kuj tseem siv rau hauv kev thauj mus los ntawm nitrocellulose.
Isopropyl cawv tuaj yeem yuav hauv yuav luag txhua lub khw tshwj xeeb. Koj tuaj yeem yuav nws los ntawm lub tuam txhab muag tshuaj. Isopropyl cawv yog ib qho tshuaj tua kab mob zoo heev. Nws cov tshuaj tua kab mob ntau dua li cov ethanol. Vim nws cov khoom tshwj xeeb, isopropanol yog siv:
- hauv kev tsim cov tshuaj pleev ib ce thiab naj hoom;
- hauv kev tsim cov resins, essences, kho mob extractants;
- raws li tshuaj tua kab mob;
- ua kuab tshuaj rau recrystallization thiab ua tus neeg saib xyuas;
- hauv kev lag luam ntoo tshuaj rau kev tshem tawm cov resins ntawm ntoo;
- hauv kev lag luam rooj tog ua cov kuab tshuaj rau ntau yam nplaum thiab roj;
- nyob rau hauv kev lag luam tshuaj rau denaturing ethanol nyob rau hauv tus txheej txheem ntawm kev npaj cov dej nres;
- siv hauv aviation ua de-icer thiab aviation roj av stabilizer;
- raws li lub tshuab ntxhua khaub ncaws.
Hnub no, qhov kev thov rau isopropanol tau loj hlob sai, uas cuam tshuam nrog kev siv cov tshuaj no ua ib feem ntawm lub cev muaj zog roj raunce nws tus lej octane. Nrog rau kev siv cov cawv no, kev ua haujlwm ntawm cov roj av hauv lub cev tau zoo dua qub (detonation kuj nce, emissions ntawm cov tshuaj lom - CH, CO) txo. Feem ntau ntawm cov tuam txhab tshuaj lom neeg ntawm peb lub teb chaws yog "tub rog" nrog cov thev naus laus zis niaj hnub thiab cov khoom siv tshiab, uas ua rau lawv tsim cov khoom sib tw thiab cov khoom zoo. Los ntawm cov lus tseeb saum toj no, peb tuaj yeem xaus tias isopropanol yog cov cuab yeej siv thoob ntiaj teb thiab nrov hauv ntau qhov chaw ntawm kev tsim khoom thiab tib neeg kev ua haujlwm.
