propylene oxidehe ʻano mea koʻikoʻi kemika koʻikoʻi a me ka waena. Hoʻohana nui ʻia ia i ka synthesis o polyether polyols, polyester polyols, polyurethane, polyether amine, etc., a he mea waiwai nui ia no ka hoʻomākaukau ʻana i nā polyester polyols, he mea nui ia o ka polyurethane kiʻekiʻe. Hoʻohana pū ʻia ka propylene oxide ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā surfactant like ʻole, nā lāʻau lapaʻau, nā kemika mahiʻai, a me nā mea ʻē aʻe, a ʻo ia kekahi o nā mea waiwai nui no ka ʻoihana kemika.

Hoʻopuka ʻia ka propylene oxide e ka hoʻohemo ʻana o ka propylene me kahi catalyst. Hoʻohui ʻia ka propylene maka me ka ea i hoʻopaʻa ʻia a laila hele i loko o kahi reactor i hoʻopiha ʻia me ka catalyst. He 200-300 DEG C ka wela o ka hopena, a ma kahi o 1000 kPa ke kaomi. ʻO ka huahana hopena he hui pū me ka propylene oxide, carbon dioxide, carbon monoxide, wai a me nā mea ʻē aʻe. ʻO ka mea hoʻoheheʻe i hoʻohana ʻia i kēia pane ʻana he mea hoʻololi metala oxide catalyst, e like me ka mea hoʻoheheʻe kala kala, chromium oxide catalyst, a me nā mea ʻē aʻe. Eia kekahi, e hoʻopau ʻia ka catalyst ponoʻī i ka wā o ka hopena, no laila pono e hana hou a hoʻololi pinepine ʻia.

ʻO ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana o ka propylene oxide mai ka hui ʻana o ka hopena he mau mea koʻikoʻi loa ia i ka hana hoʻomākaukau. ʻO ke kaʻina hoʻokaʻawale maʻamau ka holoi wai, distillation a me nā ʻanuʻu ʻē aʻe. ʻO ka mua, holoi ʻia ka hui ʻana me ka wai e wehe i nā ʻāpana haʻahaʻa e like me ka propylene unreacted a me ka carbon monoxide. A laila, hoʻopili ʻia ka hui ʻana e hoʻokaʻawale i ka propylene oxide mai nā mea hoʻolapalapa kiʻekiʻe. No ka loaʻa ʻana o ka propylene oxide maʻemaʻe kiʻekiʻe, pono nā hana hoʻomaʻemaʻe hou e like me ka adsorption a i ʻole ka unuhi ʻana.

Ma keʻano laulā, ʻo ka hoʻomākaukau ʻana i ka propylene oxide he kaʻina hana paʻakikī, e koi ana i nā ʻanuʻu he nui a me ka hoʻohana ʻana i ka ikehu kiʻekiʻe. No laila, i mea e hōʻemi ai i ke kumukūʻai a me ka hopena o ke kaiapuni o kēia kaʻina hana, pono e hoʻomau i ka hoʻomaikaʻi ʻana i ka ʻenehana a me nā mea hana o ke kaʻina hana. I kēia manawa, ʻo ka noiʻi e pili ana i nā kaʻina hana hou no ka hoʻomākaukau ʻana i ka propylene oxide ka mea nui i nā kaʻina hana kūlohelohe me ka haʻahaʻa haʻahaʻa o ka ikehu a me ka hana kiʻekiʻe, e like me ka catalytic oxidation me ka hoʻohana ʻana i ka oxygen mole e like me ka oxidant, microwave-kōkua oxidation kaʻina, supercritical oxidation kaʻina, etc. , He mea nui loa ka noiʻi ʻana i nā catalysts hou a me nā ʻano hoʻokaʻawale hou no ka hoʻomaikaʻi ʻana i ka hua a me ka maʻemaʻe o ka propylene oxide a me ka hōʻemi ʻana i ke kumukūʻai hana.
