Ukuqapha ku-inthanethi kunikeza ngokushesha imiphumela yezinga lokuguqulwa, kufinyeze umjikelezo wocwaningo nentuthuko izikhathi ezingu-10 uma kuqhathaniswa nokuqapha elabhorethri ungaxhunyiwe ku-inthanethi.
I-4-Nitro-o-xylene kanye ne-3-nitro-o-xylene zibalulekile ze-organic synthesis intermediates futhi enye yezinto ezibalulekile zokusetshenziswa kokukhiqizwa kwezibulala-zinambuzane ezintsha ezingavumelani nemvelo ngokusebenza kahle okuphezulu, ubuthi obuphansi kanye nezinsalela eziphansi.Embonini, iningi lazo lihlanganiswa nge-nitrate o-xylene ne-nitrate-sulphur mix mix.Izinkomba zokuqapha ezibalulekile kunqubo ye-o-xylene nitration zihlanganisa okuqukethwe kwe-o-xylene raw materials kanye ne-isomer ratio yemikhiqizo ye-nitration, njll.
Njengamanje, indlela yokuhlaziya ilabhorethri yalezi zinkomba ezibalulekile ivamise ukuba i-chromatography ewuketshezi, edinga inqubo eyisicefe yesampula, isampula yokwelashwa kwangaphambili kanye nochwepheshe bokuhlaziya okuphrofeshinali, futhi yonke inqubo ithatha imizuzu engaphezu kwengama-30.Phakathi nokuthuthukiswa kwenqubo yokugeleza eqhubekayo yalokhu kusabela, ukusabela ngokwako kungaqedwa cishe emaminithini angu-3, futhi izindleko zesikhathi zokuhlaziya ungaxhunyiwe ku-inthanethi ziphezulu.Uma inombolo enkulu yezimo zepharamitha yenqubo idinga ukuskrinwa ngesikhathi esifushane, abacwaningi badinga indlela yesikhathi sangempela nenembile yokutholwa ku-inthanethi ukuze banikeze ngokushesha ulwazi lokuqukethwe futhi baqondise isiqondiso sokwenziwa kwenqubo ngokugcwele.
Ubuchwepheshe be-spectroscopy eku-inthanethi bunganikeza ngokushesha ulwazi lwe-spectral lwe-o-xylene, i-3-nitro-o-xylene, ne-4-nitro-o-xylene kusixazululo sokusabela.Izindawo eziphakeme zeziqongo zesici ezimakwe imicibisholo kumfanekiso ongenhla zibonisa okuqukethwe okuhlobene kwezinto ezintathu ngokulandelanayo.Emfanekisweni ongezansi, isofthiwe ihlaziya ngobuhlakani izilinganiso zezinto ezingavuthiwe kanye nokuqukethwe komkhiqizo ngaphansi kwezinqubo ezihlukene eziyi-12.Kusobala ukuthi izinga lokuguqulwa kwezinto ezingavuthiwe ngaphansi kwesimo sesi-2 liphezulu kakhulu, futhi impahla eluhlaza ngaphansi kwesimo sesi-8 cishe ayinakho ukusabela.Abacwaningi bangahlulela ngokushesha ikhwalithi yemingcele yenqubo ngokusekelwe kokuqukethwe kwezinto ezintathu kusixazululo sokusabela, bahlole ngokushesha imingcele efanelekile, futhi bakhulise ukusebenza kahle kocwaningo nentuthuko izikhathi ezingaphezu kweziyi-10.
