Hoʻolauna
Methyl propionate, i ʻike ʻia ʻo methoxyacetate. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka methyl propionate:
ʻAno maikaʻi:
- Ke ʻano: ʻO ka Methyl propionate kahi wai aniani ʻole me kahi ʻala kūikawā.
- Hoʻoheheʻe: ʻoi aku ka paʻakikī o ka methyl propionate i loko o nā waiʻona anhydrous a me nā mea hoʻoheheʻe etera, akā liʻiliʻi i ka wai.
E hoʻohana:
- Hoʻohana ʻoihana: ʻO ka methyl propionate he mea hoʻoheheʻe koʻikoʻi koʻikoʻi i hoʻohana nui ʻia i nā uhi, inks, adhesives, detergents a me nā ʻoihana ʻē aʻe.
Hanana:
Hoʻomaʻamaʻa pinepine ʻia ka hoʻomākaukau ʻana o ka methyl propionate:
CH3OH + CH3COOH → CH3COOCH2CH3 + H2O
Ma waena o lākou, hana ka methanol a me ka acetic acid ma lalo o ka hana a kahi catalyst e hana i ka methyl propionate.
ʻIke palekana:
- ʻO ka Methyl propionate kahi wai wela a pono e mālama ʻia mai nā lapalapa ākea a me nā wela kiʻekiʻe.
- ʻO ka hoʻolaha ʻana i ka methyl propionate hiki ke hoʻonāukiuki i ka maka a me ka ʻili, no laila pono e mālama ʻia.
- Hōʻalo i ka hoʻohu ʻana i ka mahu o ka methyl propionate a pono e hana ma kahi wahi i hoʻoluʻu maikaʻi ʻia.
- I ka ʻai ʻana a i ʻole ka inhalation, e ʻimi koke i ka lāʻau lapaʻau.
