ʻO ka butyl acetate, ka mea i kapa ʻia ʻo butyl acetate, he wai kala ʻole me ka ʻala ʻala ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka butyl acetate:

ʻAno maikaʻi:

- Ke ʻano: ʻO ka wai aniani ʻole

- Hui Molekala: C6H12O2

- Kaumaha Molekala: 116.16

- Māmā: 0.88 g/mL ma 25 °C (māmā)

- Lae paila: 124-126 °C (kukui)

- Lae hehee: -78 °C (kukui)

- Hiki ke hoʻoheheʻe: Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik

E hoʻohana:

- Nā noi hana: ʻO Butyl acetate kahi mea hoʻoheheʻe koʻikoʻi koʻikoʻi, i hoʻohana nui ʻia i nā pena, nā uhi, glues, inks a me nā ʻoihana ʻoihana ʻē aʻe.

- Nā hopena kemika: Hiki ke hoʻohana ʻia ma ke ʻano he substrate a me ka solvent i ka synthesis organik no ka hoʻomākaukau ʻana i nā pūhui organik ʻē aʻe.

Hanana:

ʻO ka hoʻomākaukau ʻana i ka butyl acetate e loaʻa pinepine ʻia e ka esterification o ka acetic acid a me ka butanol, kahi e koi ai i ka hoʻohana ʻana i nā catalysts acid e like me ka sulfuric acid a i ʻole phosphoric acid.

ʻIke palekana:

- Hōʻalo i ka inhalation, pili i ka ʻili a me ka ʻai ʻana, a hoʻohana i nā mīkina lima pale, nā maka aniani a me nā pale alo ke hoʻohana.

- E hoʻohana i loko o kahi wahi hoʻoluʻu maikaʻi a pale i ka ʻike lōʻihi i nā kiʻekiʻe kiʻekiʻe.

- E mālama i ka ʻāʻī a me nā mea oxidants e hōʻoia i ko lākou kūpaʻa.
