Tikanga Hononga Haukini Waro Waikawa Oxalic
I te tīmatanga, i whakamahia e tēnei tikanga te palladium me ngā tote parahi hei whakakorikori, ā, i whakahaerehia he tauhohenga hononga-wāhanga wai o te hauota waro, te hāora, te waipiro, me te waikawa hauota waimeha i te 8–11 MPa me te 90–100 °C. I te tauhohenga tuatahi ka puta te oxalate ester, kātahi ka waikurahia i raro i ngā tikanga whakamahana hei hanga i te waikawa oxalic me te waipiro e rite ana.
He pūnaha whakakorikori kotahi tēnei tikanga, he kaha te mahi, he pai te whiriwhiri, he ngāwari te whakaora, he parakore te hua, ā, he iti te parahanga whakaputa. Heoi, he nui ngā whakaritenga mō te parakore o te hauhā waro, he nui te whakamahinga, he utu nui ngā whakakorikori, ā, he nui te haumitanga.
Mā te whakamahi i te Pd/C hei whakakorikori, ka honoa te hauota waro me te nitrite ester hei hanga i te oxalate ester i te 130 °C me te pēhanga hauātea, me te hauota hauota hei hua taha. Ka whiwhihia te waikawa oxalic me te waipiro e rite ana mā te whakawhaiti i te oxalate ester. Ka whakawhaitihia anō te otinga waipiro kua wehea hei hanga i te nitrite ester, ka taea te hangarua.
Kua whakahaerehia e te Fujian Institute of Structure of Matter, Chinese Academy of Sciences, he rangahau mō te ōwehenga o ngā rauemi mata me ngā āhuatanga tere ā-wāhi i runga i te hanganga matū o te dimethyl oxalate i roto i te rangahau o ngā matū whakakorikori mō te hononga matū whakakorikori o te CO ki te waikawa oxalic i te pēhanga hauātea, ā, kua tīpakohia ngā āhuatanga tauhohenga e tika ana. Nā te matū whakakorikori Pd (2.0%)/α-Al₂O₃ kua whakapaitia i tutuki ai te hua ā-wāhi-wā o te 999 g/L·h i raro i ngā āhuatanga o te pēhanga hauātea, 140 °C, CO/CH₃ONO=1.5, me te tere ā-wāhi o te 3000/h. I mahi tahi te whare wānanga me te Fujian Petrochemical Design Institute me te Fujian Nanqing Ammonia Plant ki te whakahaere i tētahi whakamātautau whakamātautau 100 tana/ia o te whakaora i te CO mai i te horoinga parahi ammonia hangai, te hanganga matū whakakorikori o te dimethyl oxalate i te pēhanga hauātea, me te hydrolysis ki te waikawa oxalic.
Ki te whakataurite ki te tikanga wai-wāhanga, he nui te whiriwhiringa o tēnei tikanga, he māmā te tukanga, he teitei te parakore o te hua, ā, he iti te utu whakaputa. Ka taea te whakamahi i te hau māori, te waro rānei hei rauemi mata, ā, ka taea hoki te whakamahi i te hauota waro i tangohia mai i te horoinga parahi haukini, i te oumu whākawa kōwhai rānei, i te oumu pupuhi, me te hau hiku whakawhiti hei pūtake hauota waro. I te wa ano, ka taea e ia te whakarato rauemi mata iti te utu mō te hanga ethylene glycol me te hanganga kotahi me te oxalate ester hei takawaenga.

Shandong Pulisi Chemical Co., Ltd. | Kaiwhakarato Waikawa Oxalic Premium
I whakatūria i te tau 2006, he tohunga a Pulisi Chemical ki te waikawa oxalic tino parakore (CAS 144-62-7) e tutuki ana i ngā paerewa kaweake o te ao mō ngā momo ahumahi me ngā momo parakore. Mā tā mātou whare hanga kei Zibo ka whakarite kia tino tika te whakahaere kounga, me te waikawa oxalic kounga ahumahi e whakamanamana ana ki te iti rawa o te 96% te parakore me te kounga parakore e eke ana ki te 99.6% te parakore—e tutuki ana i ngā whakaritenga ahumahi kanorau.
He mea motuhake te waikawa oxalic mō tōna wairewatanga pai me ōna āhuatanga matū pumau, he rauemi mata maha-whakamahinga puta noa i ngā rāngai. I roto i te tukatuka whakarewa, ka tangohia pai e ia te waikura me ngā paparanga waikura mata mai i te maitai, te konumohe, me te parahi, ka whakarei ake i te piri o te paninga mō ngā mahi motuka, rererangi, me te whakakikorua hiko. I roto i ngā kakahu, ka mahi hei kaihoko whakama me te whakapiri tae e pai ana ki te taiao, ka whakapai ake i te pumau me te kanapa o te tae o te kakahu.
Hei tāpiritanga, he whānuitia te whakamahinga i roto i te hanga rongoā, te tukatuka rakau, te tango konganuku onge, me te maimoatanga unahi wai. Kua whakamanahia e ISO 9001 me EU REACH, ka tukuna e mātou he takai paerewa 25kg mō ngā ota nui, kia tika ai te tuku puta noa i te ao. Ahakoa mō te hanga ahumahi nui, mō ngā tono teitei rānei, ka tukuna e Pulisi Chemical te kounga pumau me te tautoko ngaio.
