Ka whakamahia e mātou ngā pihikete hei whakapai ake i tō wheako. Mā te haere tonu ki te tirotiro i tēnei pae, e whakaae ana koe ki tā mātou whakamahinga o ngā pihikete. Ētahi atu kōrero.
E arotahi ana tēnei tuhinga ki ngā āhuatanga waikawa o te mata o ngā whakakorikori waikura me ngā tautoko (γ-Al2O3, CeO2, ZrO2, SiO2, TiO2, HZSM5 zeolite) me te whakataurite i te kitenga o ō rātou mata mā te ine i te mimiti haukini kua whakaritea ki te pāmahana (ATPD). He tikanga pono, he tikanga māmā hoki te ATPD, e whai muri i te whakakīia ki te haukini i te pāmahana iti, ka huri te pāmahana o te mata, ka mutu ka mimitihia ngā ngota ngota me te tohatoha pāmahana.
Mā te tātaritanga rahinga me/ranei te tātaritanga kounga o te tauira mimiti, ka taea te tiki mōhiohio mō te kaha o te mimiti/momomitanga me te nui o te haukini e mimitihia ana ki te mata (te mimiti haukini). Hei ngota taketake, ka taea te whakamahi i te haukini hei tirotiro hei whakatau i te waikawa o te mata. Ka taea e ēnei raraunga te āwhina ki te mārama ki te whanonga whakatere o ngā tauira, ā, ka āwhina anō hoki ki te whakatikatika i te hanganga o ngā pūnaha hou. Engari i te whakamahi i te taputapu kite TCD tuku iho, i whakamahia he ine papatipu quadrupole (Hiden HPR-20 QIC) i roto i te mahi, i honoa ki te taputapu whakamātautau mā te capillary wera.
Mā te whakamahinga o te QMS ka taea e tātou te wehewehe ngāwari i waenga i ngā momo rerekē kua mimitia mai i te mata, me te kore e whakamahi i ngā tātari matū, ā-tinana rānei, me ngā mahanga ka pā kino ki te tātari. Mā te tautuhinga tika o te pūmanawa whakakoi o te taputapu ka āwhina i te aukati i te pakaru o ngā ngota wai me te whakararuraru i te tohu haukini m/z. I tātarihia te tika me te pono o ngā raraunga mimiti haukini kua whakaritea ki te pāmahana mā te whakamahi i ngā paearu ariā me ngā whakamātautau whakamātautau, e whakaatu ana i ngā pānga o te aratau kohikohi raraunga, te hau kawe, te rahi matūriki, me te āhuahanga tauhohenga, e whakaatu ana i te ngāwari o te tikanga i whakamahia.
He uaua ngā momo ATPD o ngā rauemi katoa e akohia ana, e horapa ana i te whānuitanga 423-873K, engari ko te cerium, e whakaatu ana i ngā tihi mimiti whaiti kua oti te whakatau, e tohu ana i te waikawa iti ōrite. E whakaatu ana ngā raraunga tauanga i ngā rerekētanga o te mimiti haukini i waenga i ētahi atu rauemi me te silica neke atu i te kotahi te raupapa o te rahi. Mai i te mea e whai ana te tohatoha ATPD o te cerium i te pihi Gaussian ahakoa te kapi o te mata me te tere whakamahana, ka whakaahuahia te whanonga o te rauemi e akohia ana hei raina o ngā mahi Gaussian e whā e pā ana ki te huinga o ngā rōpū pae waenga, ngoikore, kaha, me te tino kaha. Kia oti te kohikohi i ngā raraunga katoa, ka whakamahia te tātaritanga tauira ATPD hei āwhina i te whiwhi mōhiohio mō te kaha mimiti o te ngota whakamātautau hei mahi o ia pāmahana mimiti. Ko te tohatoha kaha tāpiri mā te wāhi e tohu ana i ngā uara waikawa e whai ake nei i runga i ngā uara kaha toharite (i roto i te kJ/mol) (hei tauira, kapi mata θ = 0.5).
Hei tauhohenga tirotiro, i whakamaroketia te propene i te isopropanol hei tiki atu i ngā kōrero mō te mahi a ngā rauemi e rangahauhia ana. He rite tonu ngā hua i puta ki ngā inenga ATPD o mua e pā ana ki te kaha me te nui o ngā pae waikawa mata, ā, i taea ai hoki te wehewehe i waenga i ngā pae waikawa Brønsted me Lewis.
Pikitia 1. (Mauī) Te wetewete i te kōtaha ATPD mā te whakamahi i te mahi Gaussian (ko te rārangi ira kōwhai te tohu o te kōtaha i hangaia, ko ngā ira pango he raraunga whakamātautau) (matau) Te mahi tohatoha pūngao mimiti haukini i ngā wāhi rerekē.
