Kodi Propionic Acid ndi chiyani?

Propionic acid, yomwe imadziwikanso kuti methylacetic, ndi mafuta amfupi okhala ndi mafuta ochepa.

Mankhwala a propionic acid ndi CH3CH2COOH, nambala ya CAS ndi 79-09-4, ndipo kulemera kwa maselo ndi 74.078

Propionic acid ndi madzi amadzimadzi opanda mtundu, owononga komanso onunkhira.Propionic acid imasakanikirana ndi madzi, imasungunuka mu ethanol, ether ndi chloroform.

Kugwiritsiridwa ntchito kwakukulu kwa propionic acid: zotetezera chakudya ndi zoletsa mildew.Itha kugwiritsidwanso ntchito ngati choletsa zinthu zapakatikati-viscous monga mowa.Amagwiritsidwa ntchito ngati zosungunulira za nitrocellulose ndi plasticizer.Amagwiritsidwanso ntchito popanga zitsulo za nickel plating, kukonza zakudya zokometsera, ndi kupanga mankhwala, mankhwala ophera tizilombo, ndi antifungal agents.

1. Zosungira zakudya

Mphamvu ya anti-fungal ndi nkhungu ya propionic acid ndi yabwino kuposa ya benzoic acid pamene pH mtengo uli pansi pa 6.0, ndipo mtengo wake ndi wotsika kuposa wa sorbic acid.Ndi imodzi mwazosungira zakudya zoyenera.

2. Mankhwala a herbicides

M'makampani ophera tizilombo, propionic acid imatha kugwiritsidwa ntchito kupanga propionamide, yomwe imapanganso mitundu ina ya herbicide.

3. Zonunkhira

M'makampani onunkhira, propionic acid imatha kugwiritsidwa ntchito popanga mafuta onunkhira monga isoamyl propionate, linalyl, geranyl propionate, ethyl propionate, benzyl propionate, ndi zina zambiri, zomwe zingagwiritsidwe ntchito muzakudya, zodzoladzola, zonunkhira za sopo.

4. Mankhwala osokoneza bongo

M'makampani opanga mankhwala, zotumphukira zazikulu za propionic acid ndi vitamini B6, naproxen, ndi Tolperisone.Propionic acid imakhala ndi zoletsa zofooka pakukula kwa fungal mu vitro komanso mu vivo. Itha kugwiritsidwa ntchito pochiza dermatophytes.

Kusamalira ndi kusunga propionic acid

Njira zodzitetezera: ntchito yotsekedwa, kulimbikitsa mpweya wabwino.Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsata ndondomeko zoyendetsera ntchito.Zokhala ndi zida zotetezera.

Kusamala Posungira: Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino.Khalani kutali ndi gwero la moto ndi kutentha.Kutentha kwa nyumba yosungiramo zinthu sikuyenera kupitirira 30 ℃.Sungani chidebe chotsekedwa mwamphamvu.Iyenera kusungidwa mosiyana ndi oxidizing wothandizira, kuchepetsa wothandizila ndi zamchere.
