Propionic Acid yog dab tsi?

Propionic acid, tseem hu ua methylacetic, nws yog ib qho luv luv-chain saturated fatty acid.

Cov tshuaj formula ntawm propionic acid yog CH3CH2COOH, CAS naj npawb yog 79-09-4, thiab molecular hnyav yog 74.078

Propionic acid yog xim tsis muaj xim, corrosive oily kua nrog pungent tsw.Propionic acid yog miscible nrog dej, soluble hauv ethanol, ether thiab chloroform.

Kev siv tseem ceeb ntawm propionic acid: zaub mov preservatives thiab mildew inhibitors.Nws kuj tseem siv tau los ua ib qho inhibitor ntawm nruab nrab-viscous tshuaj xws li npias.Siv ua nitrocellulose hnyav thiab plasticizer.Nws kuj tseem siv rau hauv kev npaj cov tshuaj nickel plating, kev npaj cov khoom noj khoom haus, thiab kev tsim cov tshuaj, tshuaj tua kab, thiab tshuaj tua kab mob.

1. Khoom noj khoom haus preservatives

Kev tiv thaiv kab mob thiab pwm cov nyhuv ntawm propionic acid zoo dua li ntawm benzoic acid thaum pH tus nqi qis dua 6.0, thiab tus nqi qis dua li ntawm sorbic acid.Nws yog ib qho ntawm cov khoom noj khoom haus zoo tshaj plaws.

2. Tshuaj tua kab mob

Hauv kev lag luam tshuaj tua kab, propionic acid tuaj yeem siv los tsim propionamide, uas ua rau qee yam tshuaj tua kab mob.

3. Cov txuj lom

Hauv kev lag luam tshuaj tsw qab, propionic acid tuaj yeem siv los npaj cov tshuaj tsw qab xws li isoamyl propionate, linalyl, geranyl propionate, ethyl propionate, benzyl propionate, thiab lwm yam, uas tuaj yeem siv rau hauv cov khoom noj, tshuaj pleev ib ce, xab npum fragrances.

4. Tshuaj

Hauv kev lag luam kws tshuaj, lub ntsiab derivatives ntawm propionic acid muaj xws li vitamin B6, naproxen, thiab Tolperisone.Propionic acid muaj cov nyhuv inhibitory tsis muaj zog ntawm cov kab mob fungal hauv vitro thiab hauv vivo.Nws tuaj yeem siv rau kev kho mob dermatophytes.

Kev tuav thiab khaws cia ntawm propionic acid

Kev ceev faj ua haujlwm: kaw kev ua haujlwm, ntxiv dag zog rau qhov cua.Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm.Nruab nrog cov khoom siv kev nyab xeeb.

Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias.Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub.Warehouse kub yuav tsum tsis pub tshaj 30 ℃.Khaws lub thawv kaw kom nruj.Nws yuav tsum tau muab cais tawm ntawm oxidizing tus neeg sawv cev, txo cov neeg ua haujlwm thiab alkalis.
