Acetonehe wai waihoʻoluʻu ʻole me ka ʻala ikaika. Hoʻohana nui ʻia ia i nā ʻoihana like ʻole, e like me ka lāʻau lapaʻau, ka ʻaila, kemika, a me nā mea ʻē aʻe.

Hoʻopaʻa pahu acetone 

 

ʻO ka hana ʻana o ka acetone ka nui o nā ʻanuʻu ʻelua: ʻo ka hana mua ka hana ʻana i ka acetone mai ka acetic acid ma o ka catalytic reduction, a ʻo ka lua o ka hana e hoʻokaʻawale a hoʻomaʻemaʻe i ka acetone.

 

I ka hana mua, hoʻohana ʻia ka acetic acid e like me ka mea maka, a hoʻohana ʻia ka catalyst e hoʻokō i ka hopena hoʻemi catalytic e loaʻa ai ka acetone. ʻO ka pauka zinc, pauka hao, a pēlā aku. Penei ke ʻano o ka hopena: CH3COOH + H2CH3COCH3. ʻO ka mahana hopena he 150-250, a he 1-5 MPa ke kaomi hana. Hoʻoulu hou ʻia ka pauka zinc a me ka pauka hao ma hope o ka hopena a hiki ke hoʻohana pinepine ʻia.

 

I ka lua o ka ʻanuʻu, ua hoʻokaʻawale ʻia ka hui ʻana me ka acetone a hoʻomaʻemaʻe ʻia. Nui nā ʻano no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i ka acetone, e like me ke ʻano distillation, absorption method, extraction method, etc. Hoʻohana kēia ʻano hana i nā wahi paila like ʻole o nā mea e hoʻokaʻawale iā lākou ma ka distillation. He haʻahaʻa ko Acetone wahi paila a me ka mahu kiʻekiʻe. No laila, hiki ke hoʻokaʻawale ʻia mai nā mea ʻē aʻe ma o ka distillation ma lalo o kahi ʻenekini kiʻekiʻe ma ka wela haʻahaʻa. Hoʻouna ʻia ka acetone i hoʻokaʻawale ʻia i ke kaʻina hana aʻe no ka mālama hou ʻana.

 

I ka hōʻuluʻulu ʻana, ʻo ka hana ʻana o ka acetone e loaʻa i ʻelua mau ʻanuʻu: catalytic reduction o ka acetic acid e loaʻa ai ka acetone a me ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i ka acetone. ʻO ka Acetone kahi mea waiwai nui i ka ʻaila, kemika, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe. Loaʻa iā ia ka laulā o nā noi ma nā ʻano o ka ʻoihana a me ke ola. Ma kahi o nā kaʻina i luna, aia kekahi mau ala ʻē aʻe no ka hana ʻana i ka acetone, e like me ke ʻano fermentation a me ke ʻano hydrogenation. Loaʻa i kēia mau ʻano ko lākou mau hiʻohiʻona ponoʻī a me nā pono i nā noi like ʻole.
