Propionic acid, nke a makwaara dị ka methylacetic, ọ bụ acid fatty juputara na nkenke.
Usoro kemịkalụ nke propionic acid bụ CH3CH2COOH, nọmba CAS bụ 79-09-4, na ịdị arọ molekụla bụ 74.078
Propionic acid bụ mmiri ara ehi na-emebi emebi na-esi ísì ụtọ.Propionic acid na-ejikọta ya na mmiri, soluble na ethanol, ether na chloroform.
Isi ojiji nke propionic acid: ihe nchekwa nri na ihe mgbochi mildew.Enwere ike iji ya mee ihe dị ka onye na-egbochi ihe ndị na-ajụ ihe na-adịghị mma dị ka biya.A na-eji ya dị ka ihe mgbaze nitrocellulose na plasticizer.A na-ejikwa ya na-akwadebe ihe ngwọta nke nickel plating, nkwadebe nke ụtọ nri, na imepụta ọgwụ, ọgwụ pesticides, na ihe ndị na-egbu egbu.
1. Ihe nchekwa nri
Mmetụta mgbochi fungal na ebu nke propionic acid dị mma karịa nke benzoic acid mgbe uru pH dị n'okpuru 6.0, na ọnụahịa dị ala karịa nke sorbic acid.Ọ bụ otu n'ime ezigbo ihe nchekwa nri.
2. Herbicides
N'ụlọ ọrụ na-ahụ maka ọgwụ pesticide, a pụrụ iji propionic acid mepụta propionamide, nke n'aka nke ya na-emepụta ụfọdụ ụdị ahịhịa.
3. Ngwa nri
Na ụlọ ọrụ na-esi ísì ụtọ, a pụrụ iji propionic acid kwadebe ihe na-esi ísì ụtọ dị ka isoamyl propionate, linalyl, geranyl propionate, ethyl propionate, benzyl propionate, wdg, nke a pụrụ iji na nri, ihe ịchọ mma, ihe na-esi ísì ụtọ.
4. Ọgwụ
Na ụlọ ọrụ na-emepụta ọgwụ, ihe ndị bụ isi nke propionic acid gụnyere vitamin B6, naproxen, na Tolperisone.Propionic acid nwere mmetụta mgbochi na-adịghị ike na uto fungal na vitro na in vivo. Enwere ike iji ya mee ihe maka ọgwụgwọ nke dermatophytes.
Ijikwa na nchekwa nke propionic acid
Akpachara anya na-arụ ọrụ: arụ ọrụ mechiri emechi, mee ka ikuku ikuku sie ike.Ndị na-arụ ọrụ ga-enwerịrị ọzụzụ pụrụ iche ma rube isi na usoro ọrụ.Ejiri akụrụngwa nchekwa.
