ʻO 4-Nitro-o-xylene a me 3-nitro-o-xylene nā mea koʻikoʻi o ka synthesis organic intermediates a me kekahi o nā mea waiwai nui no ka hana ʻana i nā pesticides hou e pili ana i ke kaiapuni me ka hana kiʻekiʻe, haʻahaʻa haʻahaʻa a me ke koena haʻahaʻa.I ka ʻoihana, hoʻohui ʻia ka hapa nui o lākou e ka nitrating o-xylene me ka nitrate-sulfur i hui pū ʻia.ʻO nā hōʻailona kiaʻi nui i ke kaʻina hana nitration o-xylene me ka ʻike o ka o-xylene raw material a me ka isomer ratio o nā huahana nitration, etc.
I kēia manawa, ʻo ke kaʻina hana hoʻokolohua no kēia mau hōʻailona koʻikoʻi ʻo ia ka chromatography wai, kahi e koi ai i kahi kaʻina hana paʻakikī o ka laʻana, ka laʻana pre-treatment a me nā ʻenehana loiloi ʻoihana, a ʻoi aku ke kaʻina holoʻokoʻa ma mua o 30 mau minuke.I ka wā o ka hoʻomohala ʻana i ke kaʻina kahe hoʻomau no kēia pane, hiki ke hoʻopau ʻia ka hopena iā ia iho ma kahi o 3 mau minuke, a kiʻekiʻe ke kumukūʻai o ka nānā ʻana ma waho.Inā pono e nānā ʻia ka nui o nā kūlana hoʻohālikelike kaʻina i loko o kahi manawa pōkole, pono nā mea noiʻi i kahi ala ʻike pūnaewele i ka manawa maoli a pololei e hāʻawi koke i ka ʻike maʻiʻo a alakaʻi i ke kuhikuhi o ka loiloi kaʻina.
Hiki i ka ʻenehana spectroscopy pūnaewele ke hāʻawi koke i ka ʻike kikoʻī o ka o-xylene, 3-nitro-o-xylene, a me 4-nitro-o-xylene i loko o ka hopena hopena.Hōʻike ʻia nā ʻāpana kiʻekiʻe o nā piko kikoʻī i kaha ʻia e nā pua ma ke kiʻi ma luna aʻe i ka pili o nā mea ʻekolu.Ma ke kiʻi ma lalo nei, e kālailai naʻauao ka polokalamu i ka waiwai maka a me ka ʻike huahana ma lalo o 12 mau kaʻina hana like ʻole.ʻIke ʻia ka mea kiʻekiʻe loa o ka hoʻololi ʻana o nā mea maka ma lalo o ke kūlana 2, a ʻo ka mea maka ma lalo o ke kūlana 8 aneane ʻaʻohe pane.Hiki i nā mea noiʻi ke hoʻoholo koke i ka maikaʻi o nā kaʻina hana e pili ana i nā mea o nā mea ʻekolu i loko o ka hopena hopena, e nānā wikiwiki i nā ʻāpana maikaʻi loa, a hoʻonui i ka pono o ka noiʻi a me ka hoʻomohala ʻana ma mua o 10 mau manawa.
