He aha ka Propionic Acid?

ʻO ka waikawa propionic, i kapa ʻia ʻo methylacetic, he ʻakika momona saturated.

ʻO ke kumu kemika o ka waikawa propionic ʻo CH3CH2COOH, ʻo ka helu CAS ʻo 79-09-4, a ʻo ke kaumaha molekala ʻo 74.078

ʻO ka waika propionic he wai ʻaila ʻaʻole waihoʻoluʻu me ka ʻala ʻala.Hiki ke hoʻopili ʻia ka waikawa propionic me ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol, etera a me ka chloroform.

ʻO ka hoʻohana nui ʻana o ka propionic acid: nā mea mālama meaʻai a me nā mea hoʻopuʻi maloʻo.Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻokaʻawale i nā mea liʻiliʻi-viscous e like me ka pia.Hoʻohana ʻia e like me ka solvent nitrocellulose a me ka plasticizer.Hoʻohana ʻia ia i ka hoʻomākaukau ʻana i nā hopena nickel plating, ka hoʻomākaukau ʻana i nā ʻono meaʻai, a me ka hana ʻana i nā lāʻau lapaʻau, pesticides, a me nā mea antifungal.

1. Nā mea mālama meaʻai

ʻOi aku ka maikaʻi o ka hopena anti-fungal a me ka mold o propionic acid ma mua o ka benzoic acid i ka wā i emi ai ka pH ma lalo o 6.0, a ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka waikawa sorbic.ʻO ia kekahi o nā mea mālama meaʻai kūpono.

2. Nā lāʻau lapaʻau

I loko o ka ʻoihana pesticide, hiki ke hoʻohana ʻia ka propionic acid e hana i ka propionamide, ʻo ia hoʻi e hana i kekahi mau ʻano herbicide.

3. Mea ʻala

I ka ʻoihana ʻala, hiki ke hoʻohana ʻia ka propionic acid e hoʻomākaukau i nā mea ʻala e like me isoamyl propionate, linalyl, geranyl propionate, ethyl propionate, benzyl propionate, etc.

4. Laau laau

I loko o ka ʻoihana lāʻau lapaʻau, ʻo nā derivatives nui o ka propionic acid e komo pū me ka vitamin B6, naproxen, a me Tolperisone.Hiki ke hoʻohana ʻia ka propionic acid no ka mālama ʻana i nā dermatophytes.

Ka mālama ʻana a me ka mālama ʻana i ka waikawa propionic

Nā hana mālama: pani ʻia ka hana, hoʻoikaika i ka ea.Pono nā mea hana e hoʻomaʻamaʻa kūikawā a mālama pono i nā kaʻina hana.Hoʻolakoʻia me nā mea hana palekana.

E mālama i ka mālama ʻana: E kūʻai i loko o kahi hale kūʻai anuanu.E mālama i ke ahi a me nā kumu wela.ʻAʻole pono ka mahana o ka hale kūʻai ma mua o 30 ℃.Paʻa paʻa ka ipu.Pono e hoʻokaʻawale ʻia mai nā mea oxidizing, nā mea hoʻemi a me nā alkalis.
