Astaamaha
2,4,6-Trimethylaniline waa dhexdhexaad si weyn loogu isticmaalo dheeha, sunta cayayaanka iyo warshadaha kale.Maaddooyinka cayriin ee isku-dhafka mesitidine waa mesitylene, kaas oo ku jira batroolka.Iyadoo la xaqiijinayo wax-soo-saarka warshadaha ballaaran ee Shiinaha, wax-soo-saarka mesitylene ayaa sii waday inuu kordho, sidaas darteed horumarinta alaabteeda hoose waxay heshay dareen badan iyo dheeraad ah.Alaabada hoose ee mesitylene, sida trimellitic acid, mesitidine, iyo M acid, dhamaantood waa alaabada kiimikada ee muhiimka ah.Mesitylene waxaa loo isticmaalaa sida walxo ceeriin ah si loo farsameeyo mesitidine.Dareen-celinta nitration ee mesitylene waa furaha, kaas oo si toos ah ula xiriira qiimaha wax soo saarka iyo tayada alaabta.
Codsiga
Badeecada saafiga ah ee mesitidine waa dareere aan midab lahayn oo hufan marka ay hawada gasho, wayna fududahay in la beddelo midabka, badeecaduna badanaa waa bunni khafiif ah.Aan ku milmin biyaha, ku milma dareerayaasha organic sida ethanol iyo ether.Mesitylene waa dhexdhexaad ah dheeha, midabada organic iyo cayayaanka.Inta badan waxaa loo isticmaalaa in synthesis of dheeha.Waa dhexdhexaadka aashitada daciifka ah ee buluuga ah ee RAW.Waa dhexdhexaadka dheeha aashitada Praslin RAW.
Diyaarinta
1) 50 ml oo ah maqaar cadaadis joogto ah, ku dar 10 g oo acetic acid ah, ka dibna ku dar 13.5 g oo ah 98% nitric acid, istaag oo qabooji ilaa 25°C. si loo isticmaalo.250 mL weel afar qoor leh, ku dar 24.5 g oo acetic anhydride ah iyo 24 g oo mesitylene ah oo isku xigta, oo ku dar xalalka nitric acid ee la diyaariyey iyadoo hoos u dhaceysa adigoo walaaqaya 20-25°C.Ka dib marka daadinta la dhammeeyo, ku hayso 0～25℃ 2saac 2book 2Chemicalbook,kadibna kor u qaad ilaa 35～40℃ kuna hay 2saac.Saamaynta waxa lagu tijaabiyay chromatograph dareere ah, iyo marka mesitylene aan la helin, falcelinta waa la joojiyay.Isla'egta falcelintu waa sida soo socota:
2) Daawaynta ka dib falcelinta nitrification-ka Waxaa jira laba hab oo waaweyn oo loo isticmaalo daawaynta ka dib ee falcelinta nitrification, biyaha maydhista iyo nadiifinta.Habka biyo-dhaqidda: Ka dib marka fal-celinta nitration-ku dhammaato, ku dar qiyaastii 40g oo biyo ah dhalada, kor u qaad heerkulka 65 ℃, kala saar lakabyada inta ay kulul tahay, ku dhaq 65 ℃ biyo kulul 2 ilaa 3 jeer, wajiga organic waa nitro mesitylene.Habka Distillation: Ka dib markii falcelinta nitration-ku dhammaato, heerkulka ayaa kor loogu qaadayaa 70-80 ° C, ka dibna acetic acid ayaa laga saarayaa nadiifinta vacuum si loo helo nitro mesitylene.
