Izici
I-2,4,6-Trimethylaniline iyindawo ephakathi esetshenziswa kabanzi kumadayi, izibulala-zinambuzane nezinye izimboni.Izinto ezingavuthiwe zokwenziwa kwe-mesitidine yi-mesitylene, etholakala ku-petroleum.Ngokugcwaliseka kokukhiqizwa kwezimboni ezinkulu e-China, ukukhiqizwa kwe-mesitylene kuye kwaqhubeka kwanda, ngakho ukuthuthukiswa kwemikhiqizo yayo engezansi kuthola ukunakwa okwengeziwe.Imikhiqizo engaphansi kwe-mesitylene, njenge-trimellitic acid, i-mesitidine, ne-M acid, yonke imikhiqizo yamakhemikhali ebalulekile.I-Mesitylene isetshenziswa njengempahla eluhlaza ukuze kuhlanganiswe i-mesitidine.Ukusabela kwe-nitration kwe-mesitylene kuwukhiye, ohlobene ngokuqondile nezindleko zokukhiqiza kanye nekhwalithi yomkhiqizo.
Isicelo
Umkhiqizo omsulwa we-mesitidine uwuketshezi olungenambala futhi olusobala lapho uvezwe emoyeni, futhi kulula ukushintsha umbala, futhi umkhiqizo uvame ukuba nsundu ngokukhanyayo.Ayincibiliki emanzini, incibilika kuzincibilikisi eziphilayo njenge-ethanol ne-ether.I-Mesitylene iwumbala omaphakathi wodayi, ama-organic pigments kanye nezibulala-zinambuzane.Isetshenziswa kakhulu ekuhlanganiseni odayi.Iphakathi kwe-asidi ebuthakathaka ekhazimulayo eluhlaza okwesibhakabhaka RAW.Iphakathi kodayi we-asidi obuthakathaka i-Praslin RAW.
Ukulungiselela
1) Ku-50 mL wefaneli yokulahla ingcindezi engapheli, qala ungeze u-10 g we-acetic acid, bese wengeza u-13.5 g we-nitric acid engu-98%, yima futhi uphole ibe ngaphansi kuka-25° C. ukuze uyisebenzise.Ku-250 mL weflask enezintamo ezine, engeza u-24.5 g we-acetic anhydride kanye no-24 g we-mesitylene ngokulandelana, bese wengeza isisombululo esilungisiwe se-nitric acid dropwise ngenkathi ushukumisa ku-20-25°C.Ngemuva kokuthi ukuconsa sekuqediwe, kugcine ku-0～25℃ isikhathi esingu-2h ku-2Chemicalbook, bese ukunyusela ku-35℃ ku-40℃ bese ukugcine amahora angu-2.Ukusampula kwahlolwa nge-chromatograph ewuketshezi, futhi lapho i-mesitylene ingatholwa, ukusabela kwanqanyulwa.I-reaction equation imi kanje:
I-2) Ngemuva kokwelashwa kokusabela kwe-nitrification Kunezindlela ezimbili eziyinhloko zokwelashwa kwangemuva kokusabela kwe-nitrification, ukugeza amanzi kanye nokukhishwa kwe-distillation.Indlela yokugeza amanzi: Ngemva kokuphendula kwe-nitrate sekuphelile, engeza amanzi angaba ngu-40g eflaskni, unyuse izinga lokushisa libe ku-65℃, uhlukanise izendlalelo ngenkathi kushisa, geza ngamanzi ashisayo angu-65 ℃ izikhathi ezi-2 kuya kwezi-3, isigaba se-organic. i-nitro mesitylene.Indlela ye-distillation: Ngemva kokuphela kokusabela kwe-nitration, izinga lokushisa liyakhuphuka lifike ku-70-80°C, bese i-acetic acid isuswa nge-vacuum distillation ukuze kutholwe i-nitro mesitylene.
