Propyl Dej Cawv: Properties thiab cov kev siv

Propyl cawv muaj ib tug ntau ntawm cov ntaub ntawv sau npe. Nws yog ib qho zoo heev kuab ntawm alkaloids, ntau yam tseem ceeb roj, ib co hluavtaws resins, etc.

Muaj koob meej ntawm isopropyl cawv yog txuas mus rau lub fact tias nyob rau hauv feem ntau ntawm cov kua yog nkag soluble organic tebchaw (esters, roj, waxes, lipids, etc.). Nyob rau hauv kev lag luam, nyob rau hauv isopropanol twb npaj los ntawm ncaj qha propylene co. Lub ntsiab raw khoom siv rau lub synthesis ntawm isopropanol yog propylene feem pyrolysis roj roj thiab hluav taws roj zeb-propylene feem roj roj ntes.

Propyl cawv yog siv nyob rau hauv lub printing kev lag luam, roj av, tshuaj, kev kho mob, khoom noj khoom haus, rooj tog zaum, perfumes thiab cob industries.

Lub isopropanol yog siv nyob rau hauv luam sau dab rau humidification. Propyl cawv - lub ntsiab raw khoom rau zus tau tej cov acetone, izopropiletanoata, thiab lwm yam esters. Niaj hnub nimno zus tau tej cov yas tsis yog tsis muaj kev siv ntawm isopropanol.

Propyl cawv yog siv los ntxuav lub polypropylene. Xim thiab cov kua roj vanish kev lag luam yog ib yam khoom uas siv raws li ib tug pab hnyav, ethyl, acetyl thiab nitrocellulose. Isopropanol - ib qho ntawm feem tseem ceeb co-kuab tshuaj nyob rau hauv qhov siv thiab ua nitrovarnishes. Qhov no cov ntaub ntawv uas yog siv rau cov tsheb thauj mus los thiab nitrocellulose.

Isopropyl cawv yuav yuav nyob rau hauv yuav luag txhua txhua tshwj xeeb khw. Koj muaj peev xwm yuav nws nyob rau hauv ib lub tuam txhab uas muag tshuaj reagents. Isopropyl cawv - ib qho zoo heev antiseptic. Nws tua kab mob zog npaum li cas siab tshaj ethanol. Vim nws cov cim zog, isopropanol yog siv:

- nyob rau hauv qhov siv thiab ua tshuaj pleev ib ce thiab perfumes;

- nyob rau hauv qhov siv thiab ua resins, essences, kev kho mob extractants;

- raws li ib tug antiseptic;

- lub kuab thiab recrystallization raws li ib tug preserving neeg sawv cev;

- nyob rau hauv cov ntoo tshuaj lag luam rau cov extraction ntawm cob los ntawm ntoo;

- nyob rau hauv lub rooj tog kev lag luam raws li ib tug hnyav ntawm ntau yam adhesives thiab roj;

- nyob rau hauv lub tshuaj kev lag luam rau lub denaturing ntawm ethanol nyob rau hauv qhov kev npaj ntawm ib tug nres kua;

- nyob rau hauv aircraft siv raws li ib tug stabilizer defroster thiab aviation roj av;

- raws li ib tug uantej kua.

Tam sim no, thov yog loj hlob sai heev nyob rau hauv isopropanol, uas yog txuam nrog rau cov kev siv ntawm no substance li ib feem ntawm lub cev muaj zog roj a rau kom nws octane tooj. Siv cov cawv pab txoj kev kawm ntawm lub tsheb roj av (zoo av kuj, txo emission ntawm tej yam tshuaj lom - CH, CO). Feem ntau ntawm cov tshuaj qhauj ntawm peb lub teb chaws, "ua ntaj riam thaiv" uas niaj hnub technology thiab txoj kev cov khoom uas enables lawv yuav tsim kev sib tw thiab cov khoom zoo. Los ntawm cov saum toj no cov lus tseeb nws muaj peev xwm yuav xaus lus tias tus isopropanol - ntau yam thiab nrhiav-tom qab lub cuab tam nyob rau hauv cheeb tsam sib txawv ntawm ntau lawm thiab kev ua pej xeem.
