Iimpawu
I-2,4,6-Trimethylaniline yindawo ephakathi esetyenziswa kakhulu kwidayi, i-pesticides kunye namanye amashishini.Izinto eziluhlaza zokwenziwa kwe-mesitidine yi-mesitylene, ekhoyo kwi-petroleum.Ngokufezekiswa kwemveliso yemveliso enkulu e-China, ukuveliswa kwe-mesitylene kuye kwaqhubeka kwanda, ngoko ke ukuphuhliswa kweemveliso zayo ezisezantsi kuye kwafumana ingqalelo ngakumbi nangakumbi.Iimveliso ezisezantsi ze-mesitylene, ezifana ne-trimellitic acid, i-mesitidine, kunye ne-M acid, zonke ziyimveliso ebalulekileyo yeekhemikhali.I-Mesitylene isetyenziswa njengento ekrwada ukwenza i-mesitidine.Ukusabela kwe-nitration ye-mesitylene ngundoqo, ehambelana ngokuthe ngqo neendleko zemveliso kunye nomgangatho wemveliso.
Isicelo
Imveliso ecocekileyo ye-mesitidine ayinambala kwaye i-liquid ebonakalayo xa ibonakaliswe emoyeni, kwaye kulula ukutshintsha umbala, kwaye imveliso ihlala ibomvu.Ayinyibiliki emanzini, inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-ether.I-Mesitylene yindawo ephakathi yedayi, i-organic pigments kunye ne-pesticides.Isetyenziswa kakhulu ekudityanisweni kwedayi.Iphakathi kwe-asidi ebuthathaka eqaqambileyo eblue RAW.Yeyona ndawo iphakathi kwidayi yeasidi ebuthathaka iPraslin RAW.
Ukulungiselela
1) Kwi-50 mL yoxinzelelo oluqhubekayo lwe-funnel yokulahla i-funnel, faka kuqala i-10 g ye-acetic acid, uze udibanise i-13.5 g ye-98% ye-nitric acid, yima kwaye upholile ukuya ngaphantsi kwe-25 ° C.Kwi-250 mL yeflask enentamo ezine, yongeza i-24.5 g ye-acetic anhydride kunye ne-24 g ye-mesitylene ngokulandelelana, kwaye wongeze isisombululo esilungisiweyo se-nitric acid dropwise ngelixa uvuselela ku-20-25 ° C.Emva kokuba ukuthontsiza kugqityiwe, yigcine ku-0～25℃ nge-2h kwi-2Chemicalbook, uze uyinyuse iye ku-35℃40℃ kwaye uyigcine kangange-2h.Isampuli yavavanywa nge-chromatograph yolwelo, kwaye xa i-mesitylene ingabonwa, ukusabela kuye kwapheliswa.I-reaction equation imi ngolu hlobo lulandelayo:
2) Emva kokunyangwa kwe-nitrification reaction Kukho iindlela ezimbini eziphambili zokwenza unyango lwe-nitrification reaction, ukuhlamba amanzi kunye ne-distillation.Indlela yokuhlamba amanzi: Emva kokuba i-nitration iphelile, yongeza malunga ne-40g yamanzi kwi-flask, nyusa ubushushu ukuya kwi-65 ℃, yahlula iileya ngelixa ishushu, hlamba ngamanzi ashushu angama-65 ℃ amaxesha amabini ukuya kwa-3, isigaba se-organic. yi nitro mesitylene.Indlela yokucoca: Emva kokuba i-nitration reaction iphelile, ubushushu bunyuswa ukuya kwi-70-80 ° C, kwaye i-acetic acid isuswe nge-vacuum distillation ukufumana i-nitro mesitylene.
