Hoʻolauna

Methyl butyrate. ʻO kēia ka hoʻolauna ʻana i kekahi o nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka methyl butyrate:

 

ʻAno maikaʻi:

- ʻO ka methyl butyrate kahi wai hiki ke hoʻopau ʻia i ka wai.

- He mea hiki ke hoʻoheheʻe maikaʻi ʻia, hiki ke hoʻoheheʻe ʻia i loko o nā waiʻona, nā eter a me kekahi mau mea hoʻoheheʻe organik.

 

E hoʻohana:

- Hoʻohana maʻamau ʻia ʻo Methyl butyrate ma ke ʻano he solvent, plasticizer a me ka diluent i nā uhi.

- Hiki ke hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik no ka hoʻomākaukau ʻana i nā mea ʻē aʻe.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka methyl butyrate ma ka hana ʻana i ka ʻakika butyric me ka methanol ma lalo o nā kūlana acidic. Penei ka hoohalike pane.

CH3COOH + CH3OH → CH3COOCH2CH2CH3 + H2O

- Hoʻokō pinepine ʻia ka hopena ma ka hoʻomehana ʻana me kahi catalyst (e laʻa, sulfuric acid a i ʻole ammonium sulfate).

 

ʻIke palekana:

- ʻO ka methyl butyrate kahi wai wela e hiki ke ʻā i ka wā e ʻike ʻia ai i nā lapalapa ahi, nā wela kiʻekiʻe, a i ʻole nā ​​​​mea hoʻonanea kūlohelohe.

- ʻO ka pili ʻana me ka ʻili a me nā maka hiki ke hoʻonāukiuki a me ke kuni, pono e mālama ʻia.

- ʻO ka methyl butyrate kekahi mea ʻawaʻawa, no laila pono e pale ʻia no ka inhalation a me ka ʻai ʻole ʻana, a hoʻohana ʻia ma lalo o nā kūlana maikaʻi.

- Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, nā waikawa a me nā alkali i ka wā e hoʻohana ai a mālama ʻia paha.
