habka synthesis

1. Waxaa lagu helaa falcelinta u dhaxaysa aniline iyo methanol iyadoo ay jirto joogitaanka sulfuric acid heerkulka sare iyo cadaadiska sare.Socodka geedi socodka:1.790kg aniline, 625kg methanol, 85kg of sulfuric acid (ammonium 100%) ayaa lagu daraa digsiga falcelinta, heerkulka 210-215℃Cadaadiska 3.1MPa, falcelis 4h, ka dibna sii daaya cadaadiska, walxaha waxaa lagu sii daayaa kala-soocida, dhexdhexaadin 30% sodium hydroxide, static, iyo cusbada hoose ee ammonium quaternary waa la kala saaraa.Ka dibna 160℃, 0.7-0.9MPa falcelinta hydrolysis ee 3h, alaabada hydrolysis iyo lakabka sare ee alaabta saliidda ah oo lagu daray dhaqidda ka dib nadiifinta faakuum ee alaabta la dhammeeyey.

2. Isticmaalka methanol iyo aniline sida alaabada ceeriin ah, waxaa lagu farsameeyaa alumina kicinta iyadoo la raacayo xaaladda 200-250℃oo leh methanol xad-dhaaf ah iyo cadaadiska atmospheric.Kootada isticmaalka alaabta ceeriin: aniline 790kg/t, methanol 625kg/t, sulfuric acid 85kg/t.Diyaarinta shaybaarka waxay ka falcelin kartaa aniline leh phosphate trimethyl.

3. aniline iyo methanol isku dhafan (n aniline: n methanol≈1: 3), iyo iyada oo loo marayo bamka cabbiraadda garaaca wadnaha ee aan dib-u-celinta ahayn ee lagu duray xawaaraha 0.5h-1 ee reactor-ka ku qalabaysan kicinta, falcelinta falcelinta marka hore ee soocaha dareeraha gaaska, sEparator hoos dareeraha la ururiyey waqtiyo joogto ah ayaa laga saaray falanqaynta chromatographic.

Sannadkii 2001, Jaamacadda Nankai iyo Tianjin Ruikai Technology Development Co., Ltd. waxay si wadajir ah u sameeyeen kicinta methylation aniline oo aad waxtar u leh, waxayna xaqiiqsadeen isku-dhafka gaaska-wejiga ee N, N-dimethyl aniline.Nidaamku waa sida soo socota: Aniline dareere ah ayaa lagu qasi karaa methanol, oo uumiga ku jira munaaradda uumiga, ka dibna la galay reactor tubbada leh xawaaraha hawada ee 0.5-1.0h-1 (sariirta go'an ee reactor tubular waxay ku qalabaysan tahay nano raran -catalyst adag), oo si joogto ah loo soo saaray 250-300℃under cadaadiska atmospheric, oo leh dhalid DMA ka badan 96%.

Habka sifaynta: Inta badan waxa ku jira wasakh sida aniline iyo N-methyl aniline.N,N-dimethylaniline waxa lagu milan yahay 40% sulfuric acid waxaana lagu miiray uumiga biyaha.Sodium hydroxide ayaa lagu daraa si ay uga dhigto alkaline.Distillation waxaa lagu sii wadaa uumiga biyaha.Distillate-ka waxaa loo kala saaraa lakabyo biyo ah waxaana lagu qallajiyaa potassium hydroxide.Cadaadiska caadiga ah ee cadaadiska waxaa lagu fuliyaa joogitaanka acetic anhydride.Distillate-ka waxaa lagu dhaqaa biyo si looga saaro raadadka acetic anhydride, waxaa lagu qallajiyaa potassium hydroxide, oo ay ku xigto barium oxide, oo lagu nadiifiyo cadaadiska hoos u dhaca iyadoo ay jirto qulqulka nitrogen.Hababka kale ee lagu sifeeyo distillate-ka waxa ka mid ah in lagu daro 10% acetic anhydride iyo refluxing dhowr saacadood si meesha looga saaro aminyada aasaasiga ah iyo kuwa sare.Kadib qaboojinta, xad dhaaf ah 20% hydrochloric acid ayaa lagu daraa waxaana lagu soo saaraa ether.Lakabka aashitada hydrochloric waa alkaline leh alkali ka dibna waxaa laga soo saaraa ether, lakabka ether-kana waxaa lagu qallajiyaa potassium hydroxide waxaana lagu miiray cadaadiska hoos u dhaca ee hoos yimaada qulqulka nitrogen.N,N-dimethylaniline waxa kale oo loo rogi karaa cusbada picric acid, recrystallized ilaa meel dhalaalaysa oo joogto ah ka dibna ku qudhuntay 10% diirran xal aqueous sodium hydroxide.Ka dib waxaa lagu soo saaraa ether, la dhaqo oo la qalajiyo, oo lagu nadiifiyo cadaadiska hoos u dhaca.

5. Aniline, methanol iyo sulfuric acid isku dhafan ee saamiga, falcelinta uumi ee autoclave ah, wax soo saarka falcelinta by soo kabashada gargaarka cadaadiska ee methanol, ku dar dhexdhexaadinta alkali, kala soocidda ka dibna distillation by cadaadis la dhimay si loo helo alaabta.

6. N, N-dimethylaniline waxaa dhalin kara falcelinta methylation ee aniline iyo trimethyl phosphate, ka dibna laga soo saaro ether, la qalajiyey oo la jarjaray.

7. N, N-dimethylaniline waxaa lagu dhejin karaa sariirta catalytic ee Ziegler kicinta ee nidaamka copper-manganese ama nidaamka copper-zinc-chromium ee 280℃oo leh isku dhafka aniline iyo methanol ee saamiga 1: 3.5.N,N-dimethylaniline ee la helay waxaa lagu soo ururiyay 193-195℃on a 54-tab tiirarka muxaadaro tiir oo lagu soo ururiyey dhalada brown brown.Diyaarinta N,N-dimethylaniline saafi ah, N,N-dimethylaniline waxaa lagu duri karaa gaaska nitrogen sida gaasta qaada ee gaaska diyaarinta chromatograph which waxa uu leeyahay tiir phosphate bir ah.
