Acetonehe mea hoʻoheheʻe organik maʻamau, i hoʻohana nui ʻia i ka kemika, lāʻau lapaʻau, pena, paʻi a me nā ʻoihana ʻē aʻe. Loaʻa iā ia ka solubility ikaika a me ka volatility maʻalahi. Aia ka Acetone ma ke ʻano o ke aniani maʻemaʻe, akā i ka hapanui o nā hihia he hui ia o nā mea, a ʻo nā ʻano acetone ʻekolu: acetone maʻamau, isopropyl acetate a me butyl acetate.

 

ʻO ka acetone maʻamau he ʻano mea hoʻoheheʻe maʻamau me ke ʻano CH3COCH3. He kala ole, me ke ano o ka haʻahaʻa volatility, volatile wai. Loaʻa i ka acetone maʻamau kahi ākea ākea ākea, hiki ke hoʻopau i nā ʻano mea like ʻole a me nā mea anorganic. ʻO ia kekahi o nā mea waiwai koʻikoʻi i ka ʻoihana synthesis organik a he mea koʻikoʻi hoʻi ia i ka synthesis o nā pūhui organik ʻē aʻe. Eia hou, hoʻohana nuiʻia ka acetone maʻamau i kaʻoihana paʻi, kaʻiliʻili, ka lole lole a me nāʻoihana'ē aʻe.

ʻO ka isopropyl acetate kahi ʻano hui ester me ke ʻano CH3COOCH(CH3)2. ʻAʻole waihoʻoluʻu a ʻike ʻia ka wai viscous me ka volatility haʻahaʻa a me ka solubility maikaʻi. He kūpono maikaʻi ka Isopropyl acetate me ka nui o nā resins a me nā puaʻa, a hoʻohana nui ʻia i ka hana ʻana i nā pena, nā adhesives, ka paʻi ʻana i ka inika a me nā huahana ʻē aʻe. Eia kekahi, hoʻohana ʻia ka isopropyl acetate ma ke ʻano he solvent no ke kiʻiʻoniʻoni cellulose acetate a me ka cellulose triacetate fiber production.

 

ʻO ka butyl acetate kahi ʻano hui ester me ke ʻano CH3COOCH2CH2CH3. He wai aniani ʻole kala me ka haʻahaʻa haʻahaʻa a me ka solubility maikaʻi. He kūpono maikaʻi ka Butyl acetate me nā resins a me nā puaʻa he nui, a hoʻohana nui ʻia i ka hana ʻana i nā pena, adhesives, paʻi ʻīnika a me nā huahana ʻē aʻe. Eia kekahi, hoʻohana pū ʻia ka butyl acetate ma ke ʻano he mea hoʻoheheʻe no ke kiʻiʻoniʻoni cellulose acetate a me ka cellulose triacetate fiber production.

 

ʻO nā ʻano acetone ʻekolu i loaʻa i kā lākou mau hiʻohiʻona ponoʻī a me ka hoʻohana ʻana i nā ʻano like ʻole. ʻO ka acetone maʻamau ka laulā ākea ākea a hoʻohana nui ʻia i nā ʻoihana like ʻole; ʻO ka Isopropyl acetate a me ka butyl acetate he kūpono maikaʻi me nā resins a me nā puaʻa a hoʻohana nui ʻia i ka hana ʻana i nā pena, nā adhesives, ka paʻi ʻana i ka inika a me nā huahana ʻē aʻe. Eia kekahi, hoʻohana ʻia lākou e like me nā solvents no ka cellulose acetate film a me ka cellulose triacetate fiber production.
