Isopropanola ʻo ka acetone ʻelua mau mea hoʻohuihui maʻamau i loaʻa nā waiwai like akā ʻokoʻa nā hale molekala. No laila, ʻo ka pane i ka nīnau "He like ka isopropanol me ka acetone?" maopopo ole. E nānā hou kēia ʻatikala i nā ʻokoʻa ma waena o ka isopropanol a me ka acetone e pili ana i ke ʻano molekala, nā waiwai kino, nā waiwai kemika, a me nā kahua noi.
ʻO ka mea mua, e nānā kākou i ke ʻano mole o ka isopropanol a me ka acetone. ʻO ka Isopropanol (CH3CHOHCH3) he ʻano mole mole o C3H8O, aʻo ka acetone (CH3COCH3) he ʻano mole mole o C3H6O. Hiki ke ʻike ʻia mai ke ʻano molekala he ʻelua pūʻulu methyl ka isopropanol ma kēlā me kēia ʻaoʻao o ka pūʻulu hydroxyl, ʻoiai ʻaʻohe hui methyl ka acetone ma ka carbonyl carbon atom.
A laila, e nānā kākou i nā waiwai kino o ka isopropanol a me ka acetone. ʻO ka Isopropanol kahi wai ʻaʻole waihoʻoluʻu me ka helu hoʻolapalapa ʻana o 80-85 ° C a me kahi pae maloʻo o -124 ° C. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik. ʻO ka Acetone kekahi wai aniani ʻaʻohe waihoʻoluʻu me ka helu hoʻolapalapa o 56-58°C a me kahi kikoʻī o -103°C. Hiki ke hoʻoheheʻe ʻia me ka wai akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik. Hiki ke ʻike ʻia ʻoi aku ka kiʻekiʻe o ka helu hoʻolapalapa a me ka helu hau hau o ka isopropanol ma mua o ka acetone, akā ʻokoʻa ko lākou solubility i ka wai.
ʻO ke kolu, e nānā kākou i nā waiwai kemika o ka isopropanol a me ka acetone. ʻO Isopropanol kahi hui waiʻona me ka hui hydroxyl (-OH) ma ke ʻano he hui hana. Hiki iā ia ke hana me nā ʻakika e hana i nā paʻakai a komo i nā hopena hoʻololi me nā pūhui halogenated. Eia kekahi, hiki ke hoʻokahe ʻia ka isopropanol e hana i ka propene. ʻO ka Acetone kahi hui ketone me ka hui kalapona (-C=O-) ma ke ʻano he hui hana. Hiki iā ia ke hana me nā ʻakika e hana i nā esters a komo i nā hopena hou me nā aldehydes a i ʻole ketones. Eia kekahi, hiki i ka acetone ke polymerized e hana i ka polystyrene. Hiki ke ʻike ʻia he ʻokoʻa loa ko lākou mau waiwai kemika, akā aia ko lākou mau hiʻohiʻona ponoʻī i nā hopena kemika.
ʻO ka hope, e nānā kākou i nā kahua noi o ka isopropanol a me ka acetone. Hoʻohana nui ʻia ʻo Isopropanol i nā lāʻau lapaʻau, nā kemika maikaʻi, nā pesticides, textiles, a me nā mea ʻē aʻe. Eia kekahi, hoʻohana ʻia ia no ka synthesis o nā pūhui organik a me nā polymers. Hoʻohana nui ʻia ka Acetone no ka hana ʻana i nā mea hoʻohui a me nā polymers ʻē aʻe, ʻoi aku ka nui no ka hana ʻana i ka resin polystyrene a me ka resin polyester unsaturated, no laila ua hoʻohana nui ʻia i nā māla o ka plastic, textile, rubber, paint, etc. e hoʻohana pū ʻia ma ke ʻano he mea hoʻoheheʻe kumu nui no ka unuhi ʻana a me ka hoʻokaʻawale ʻana i nā mea kūlohelohe.
I ka hōʻuluʻulu manaʻo, ʻoiai ʻo ka isopropanol a me ka acetone kekahi mau waiwai like i ka helehelena a me nā kahua hoʻohana, ʻokoʻa loa ko lākou mau molekala a me nā waiwai kemika. No laila, pono mākou e hoʻomaopopo pono i kā lākou ʻokoʻa i mea e hoʻohana maikaʻi ai iā lākou i ka hana hana a me ka hana noiʻi.
