Erucic Acid CAS 112-86-7 yog dab tsi?

Erucic Acid yog ib qho siv lead ua zoo li koob tsis muaj xim. Melting point 33.5 ℃, boiling point 381.5 ℃ (decomposition), 358 ℃ (53.3kPa), 265 ℃ (2.0kPa), relative density 0.86 (55 ℃), refractive index 1.4534 (45 ℃), CAS 112-86-7. Yaj tau zoo heev hauv ether, yaj tau hauv ethanol thiab methanol, tsis yaj hauv dej. Cov roj rapeseed lossis roj mustard uas tsim los ntawm rapeseed, nrog rau cov noob ntawm ntau lwm cov nroj tsuag cruciferous, muaj cov erucic acid ntau. Qee cov rog tsiaj hauv dej hiav txwv, xws li roj ntses cod, kuj muaj erucic acid.

Daim Ntawv Thov

1. Kev lag luam (feem ntau)

Cov tshuaj surfactants thiab cov tshuaj ntxuav: Erucic acid tuaj yeem ua tiav los ntawm hydrogenation, sulfonation, amidation thiab lwm yam tshuaj tiv thaiv los tsim cov erucic acid amide, sulfonated erucic acid xab npum thiab lwm yam khoom, uas yog siv los ua cov roj nplua nyeem ntxiv (kom txo qhov kev sib txhuam ntawm cov khoom siv), cov roj nplua nyeem yas (txhawm rau txhim kho qhov fluidity ntawm cov yas ua, xws li polyethylene thiab polypropylene), thiab cov khoom siv raw rau cov tshuaj ntxuav (txhawm rau txhim kho kev tshem tawm cov pa phem thiab muaj kev puas tsuaj zoo dua li cov roj av surfactants).

Cov txheej thiab cov kua mem: Cov qauv ntev ntawm Erucic acid tuaj yeem txhim kho qhov yooj ywm thiab kev nplaum ntawm cov txheej thiab tuaj yeem siv ua cov khoom siv raw rau alkyd resins thiab epoxy resins. Erucic acid yog siv los npaj cov txheej tiv thaiv xeb thiab cov kua mem luam ntawv (tshwj xeeb tshaj yog cov kua mem ntim khoom yooj ywm, uas txo qhov nkag mus rau hauv cov yeeb yaj kiab).

Cov Khoom Siv Ua Kom Zoo Nkauj: Erucic acid, ua ib feem ntawm cov roj ntuj, siv tau rau hauv cov khoom xws li tshuaj pleev ntsej muag, tshuaj pleev ib ce, thiab tshuaj pleev di ncauj, ua lub luag haujlwm hauv kev ua kom daim tawv nqaij noo thiab noj qab haus huv. Tib lub sijhawm, nws tuaj yeem txhim kho qhov kev xav ntawm daim tawv nqaij ntawm cov khoom (tsis txhob ua kom rog), thiab muaj kev khaus tsawg.

Lwm yam kev siv hauv kev lag luam: Nws yog siv rau hauv kev npaj nylon 1313 (cov yas engineering uas tiv taus kub siab siv rau hauv cov khoom siv hluav taws xob thiab cov khoom siv tsheb), biodiesel (ua cov khoom siv raw rau cov roj fatty acids ntev los txhim kho qhov kub qis ntawm diesel).

2. Kev lag luam zaub mov (Cov ntsiab lus yuav tsum raug tswj hwm nruj me ntsis)

Cov khoom xyaw ntawm cov roj noj tau ib txwm muaj: Hauv cov roj rapeseed ib txwm tsis tau txhim kho, erucic acid yog ib qho ntawm cov roj fatty acid tseem ceeb. Txawm li cas los xij, vim muaj kev tshawb fawb thaum ntxov qhia tias "kev noj erucic acid ntau yuav muaj peev xwm cuam tshuam rau lub plawv", feem ntau lub tebchaws thiab thaj chaw tau teeb tsa cov kev txwv siab tshaj plaws rau cov ntsiab lus erucic acid ntawm cov roj rapeseed zaub mov (piv txwv li, Tuam Tshoj thiab European Union tau teev tseg tias cov ntsiab lus erucic acid ntawm cov roj rapeseed zaub mov yuav tsum yog ≤2%, uas yog, "ob npaug qis rapeseed roj").

Cov khoom noj ntxiv: Cov kua qaub erucic ntshiab siv tau ua cov roj nplua nyeem rau cov khoom noj (xws li rau kev ua cov khoom siv ua zaub mov, uas yuav tsum ua tau raws li cov qauv qib zaub mov), lossis ua cov roj hloov (hauv cov khoom me me rau cov khoom noj uas tsis muaj calorie ntau, vim tias tib neeg lub cev zom thiab nqus cov roj fatty acids ntev qeeb qeeb).

3. Cov teb ntawm kev kho mob thiab kev tshawb fawb

Cov tshuaj nruab nrab: Tom qab kev hloov kho tshuaj, erucic acid tuaj yeem tsim ua cov khoom siv xws li erucamide thiab erucate ester, uas yog siv rau hauv kev tsim cov tshuaj txo cov roj lipid (siv nws cov khoom ntawm kev tswj cov rog metabolism) thiab cov tshuaj pleev rau ntawm daim tawv nqaij (xws li cov tshuaj pleev kom txhawb kev nkag mus rau hauv cov tshuaj).
