Hababka macmal ah

1. Aniline iyo methanol iyadoo ay joogaan aashitada sulfuric, iyada oo loo marayo heerkul sare iyo falcelin cadaadis sare. Socodka habka: 1. Ku dar 790kg oo aniline ah, 625kg oo methanol ah iyo 85kg oo aashitada sulfuric ah (100% aashitada aashitada) falgalka, xakamee heerkulka 210-215℃ iyo cadaadiska 3.1MPa, falgasho 4 saacadood, ka dibna sii daa cadaadiska, ku shub walxaha kala-soocidda, dhexdhexaadi 30% sodium hydroxide, istaag, oo kala sooc milixda aashitada ee hoose ee quaternary. Kadib falgalka hydrolysis-ka 160℃, 0.7-0.9MPa muddo 3 saacadood ah, hydrolysate-ka ka dhashay iyo saliidda sare waxaa lagu daray biyo dhaqidda iyo nadiifinta faakiyuumka si loo helo badeecada dhammaatay.

2, oo leh methanol iyo aniline oo ah walxo cayriin ah, oo ay ku jiraan xaalad methanol xad dhaaf ah, cadaadis jawiga ah, 200-250℃, iyada oo loo marayo isku-darka kataliyaha alumina. Kootada isticmaalka walxaha ceeriin: aniline 790kg/t, methanol 625kg/t, sulfuric acid 85kg/t. Diyaarinta shaybaarku waxay ka fal celin kartaa aniline iyadoo la adeegsanayo trimethyl phosphate.

3. Aniline iyo methanol isku dhafan (N aniline: N methanol ≈ 1:3) oo lagu duray fal-galiyaha oo ku qalabaysan kataliye xawaare booska ah 0.5h-1 iyada oo loo marayo bamka cabbiraadda aan garaaca wadnaha ahayn ee is-weydaarsiga ah. Dareeraha falgalka ayaa marka hore gala kala-soocidda dareeraha gaaska-galaaska galaaska, dareeraha laga soo ururiyo qaybta hoose ee kala-soociddana si joogto ah ayaa loo soo saaraa si loo falanqeeyo koromograafigga.

4. Sannadkii 2001, Jaamacadda Nankai iyo Tianjin Ruikai Science and Technology Development Co., Ltd waxay si wadajir ah u sameeyeen kataliye methylation aniline ah oo aad waxtar u leh si loo xaqiijiyo isku-darka marxaladda gaaska ee N, N-dimethylaniline. Hawshu waa sida soo socota: Ka dib marka aniline-ka dareeraha ah lagu qaso methanol saami ahaan, waxaa lagu uumi saaraa munaarad uumi-baxa ka dibna waxaa la geliyaa fal-gale tuubo leh xawaare boos ah oo ah 0.5-1.0h-1 (sariirta go'an ee fal-gale tuubada waxaa lagu qalabeeyay kataliye adag oo nanometer ah oo la taageeray) si loogu sameeyo wax soo saar joogto ah oo ah 250-300℃ iyo cadaadiska jawiga. Wax soo saarka DMA wuxuu ka sarreeyaa 96%.

Habka sifeynta: badanaa waxaa ku jira aniline, N-methyl aniline iyo waxyaabo kale oo wasakh ah. Inta lagu jiro sifeynta,N, N-dimethylaniline waxaa lagu milmaa 40% sulfuric acid waxaana la sameeyaa sifeynta uumiga. Sodium hydroxide ayaa lagu daraa si looga dhigo mid aasaasi ah. Sifeynta uumiga ayaa sii socota. Sifeynta waxaa loo kala saaraa lakab biyo ah waxaana lagu qalajiyaa potassium hydroxide. Sifeynta cadaadiska jawiga iyadoo ay joogaan acetic anhydride. Sifeynta waxaa lagu dhaqay biyo si looga saaro xaddi raad ah oo acetic anhydride ah, ka dibna lagu qalajiyo potassium hydroxide, ka dibna waxaa lagu daray barium oxide iyo sifeynta la qaboojiyey ee durdur nitrogen ah. Hababka kale ee sifeynta waxaa ka mid ah in lagu daro 10% acetic anhydride iyo dib u soo celin dhowr saacadood si looga saaro amines-ka koowaad iyo kan labaad. Ka dib qaboojinta, ku dar 20% hydrochloric acid xad dhaaf ah oo soo saar ether. Lakabka hydrochloric acid waxaa laga sameeyay alkaline iyadoo lagu daray alkali, ka dibna lagu soo saaray ether. Lakabka ether waxaa lagu qalajiyey potassium hydroxide ka dibna lagu dhalaaliyey cadaadis hoos yimaada nitrogen. N, N-dimethylaniline sidoo kale waxaa loo rogi karaa picronate, dib loo cusboonaysiin karaa ilaa meel dhalaalaysa oo joogto ah iyadoo la adeegsanayo xal biyood oo diirran oo 10% sodium hydroxide ah si uu u burburiyo picronate. Ku soo saar ether, ku dhaq biyo oo qalaji ka dib marka la nadiifiyo faakuumka.

5. Aniline, methanol iyo sulfuric acid ayaa lagu qasaa saamiga oo lagu ururiyaa autoclave-ka. Ka dib marka wax soo saarka falgalka lagu soo celiyo yareynta cadaadiska, alkali ayaa lagu daraa si loo dhexdhexaadiyo, loo kala saaro, ka dibna badeecada waxaa lagu helaa nadiifinta faakuumka.

6. Falcelinta methylation-ka ee aniline iyo trimethyl phosphate waxay soo saari kartaa N, N-dimethylaniline: ka dibna waxaa lagu soo saaraa ether, oo ah kala-soocid qalalan.

7. N, N-dimethylaniline waxaa lagu samayn karaa iyadoo lagu darayo isku darka aniline iyo methanol saamiga 1∶ 3.5 ee sariirta catalytic ee Cu-Mn ama Cu-Zn-Cr Ziegler catalyst 280℃. Natiijadu waxay ka dhalataa N, N-dimethylaniline waxaa lagu ururiyaa cutubka kala-soocidda ee 54 saxan oo u dhexeeya 193 ilaa 195℃ waxaana lagu shubaa dhalooyin galaas bunni ah. Diyaarinta chromatography saafi ah N, N-dimethylaniline, nitrogen waxay noqon kartaa gaaska side, diyaarinta chromatography gaaska oo leh tiirka Ben 犅 yaku ayaa lagu duray sixitaanka N, N-dimethylaniline, iyada oo loo marayo kala-soocidda iyo ururinta qaybta ugu sarreysa ee qaybta ugu weyn, ka dibna shaabadda dhalada galaaska ayaa laga yaabaa inay ku jirto.
