Sunta sare, kala-goynta kulaylka sare ee sii deynta gaaska aniline ee sunta ah. Waxaa lagu nuugi karaa maqaarka iyo sunta, LD501410mg/kg, xoojinta ugu badan ee la oggol yahay ee hawadu waa 5mg/m3.

Hababka kaydinta

1. Xusuus-qorka Kaydinta [25] Ku kaydi bakhaar qabow oo hawo leh. Ka ilaali dabka iyo kulaylka. Weelka ha xidho Waa in si gooni ah loo kaydiyaa asiidhka, halogens iyo kiimikooyinka cuntada, waana in aan la isku qasin. Ku qalabee noocyada u dhigma iyo tirada qalabka dagaalka dabka. Goobta wax lagu kaydiyo waa in lagu qalabeeyaa qalab daawaynta degdega ah ee daadsan iyo agabka kaydinta habboon.

2. Waxaa lagu shaabadeeyey durbaanka birta, 180kg halkii foosto. Ku kaydi meel qabow oo hawo leh. Kaydi oo rarid si waafaqsan xeerarka walxaha guban iyo sunta ah

Hababka synthetic

1. By aniline iyo methanol joogitaanka sulfuric acid, iyada oo loo marayo heerkulka sare iyo falcelinta cadaadiska sare. Qulqulka habka: 1. Ku dar 790kg aniline, 625kg methanol iyo 85kg of sulfuric acid (100% ammonium) reactor, xakamee heerkulka 210-215 ℃ iyo cadaadiska 3.1MPa, ka falceliya 4h, ka dibna sii daayo cadaadiska, Ku daadi walxaha kala-soocida, ku dhex-dhex-dhexaadiye 30% sodium hydroxide, istaag, oo kala saar milixda ammonium-ka hoose ee rubuc-qarniga ah. Markaas falcelinta hydrolysis at 160 ℃, 0.7-0.9MPa ee 3h, hydrolyzate ka dhashay iyo saliidda sare waxaa lagu daray biyo dhaqidda iyo vacuum distillation si aad u hesho alaabta la dhammeeyey.

2, oo leh methanol iyo aniline sida alaabta ceeriin, iyadoo la raacayo xaaladda methanol xad-dhaaf ah, cadaadiska atmospheric, 200-250 ℃, iyada oo loo marayo isku-dhafka alumina. 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) oo lagu duray reactor-ka ku qalabaysan kicinta xawaaraha bannaan ee 0.5h-1 iyada oo loo marayo bamka cabbiraadda garaaca wadnaha oo aan dib u celinayn. Dareeraha falcelinta ayaa marka hore gasha dareeraha gaaska- galaaska, dareeraha lagu ururiyo qaybta hoose ee kala-soocida ayaa si joogto ah loogu qaadaa falanqaynta chromatographic.

4. In 2001, Nankai University iyo Tianjin Ruikai Sayniska iyo Horumarinta Technology Co., Ltd si wadajir ah u soo saaray a aniline methylation kicinta heer sare ah oo hufan si loo ogaado synthesis wajiga gaaska ee N, N-dimethylaniline. Nidaamku waa sida soo socota: Ka dib markii aniline dareeraha lagu qaso methanol saami ahaan, wuxuu ku nuuxnuuxsaday munaarad uumiga ka dibna waxaa la galaa reactor tubbada leh xawaarihiisa 0.5-1.0h-1 (sariir go'an ee reactor tubular). waxaa lagu qalabeeyaa nanometer adag oo la taageeray) wax soo saarka joogtada ah ee 250-300 ℃ iyo cadaadiska atmospheric. Wax-soo-saarka DMA wuxuu ka sarreeyaa 96%.

Habka sifaynta: inta badan waxaa ku jira aniline, N-methyl aniline iyo wasakh kale. Inta lagu jiro sifaynta, N, N-dimethylaniline waxaa lagu milmay 40% sulfuric acid iyo uumi nadiifinta ayaa la sameeyaa. Sodium hydroxide ayaa lagu daraa si ay u noqoto mid aasaasi ah. Distillation uumiga ayaa sii socda. Distillate-ka waxaa loo kala soocaa lakabka biyaha waxaana lagu qallajiyaa potassium hydroxide. Distillation atmospheric cadaadiska joogitaanka acetic anhydride. Distillate-ka waxaa lagu maydhay biyo si loo soo saaro qaddarka raadka ee acetic anhydride, ka dibna lagu qalajiyey potassium hydroxide, oo ay ku xigto barium oxide iyo kala-saarid kala-baxsan ee qulqulka nitrogen. Hababka kale ee sifaynta waxaa ka mid ah in lagu daro 10% acetic anhydride iyo reflux dhowr saacadood si meesha looga saaro aminyada aasaasiga ah iyo kuwa sare. Ka dib qaboojinta, ku dar 20% ka badan hydrochloric acid oo ku soo saar ether. Lakabka acid hydrochloric waxaa laga sameeyay alkaline iyadoo lagu daray alkali, ka dibna laga soo saaray ether. Lakabka ether-ka ayaa lagu qallajiyey potassium hydroxide ka dibna lagu nadiifiyey cadaadis hoostiisa nitrogen. N, N-dimethylaniline waxa kale oo loo rogi karaa picronate, recrystallized ilaa meel dhalaalaysa oo joogto ah oo leh 10% diirran oo sodium hydroxide xal aqueous ah si ay u jajabiso picronate. Ku soo saar ether, ku maydh biyo oo qalaji ka dib nadiifinta faakuumka.

5. Aniline, methanol iyo sulfuric acid ayaa isku dhafan oo isku dhafan oo isku dhafan oo ku jira autoclave. Ka dib markii sheyga falcelinta lagu soo celiyo cadaadiska cadaadiska, alkali waxaa lagu daraa dhexdhexaadinta, kala-soocidda, ka dibna badeecada waxaa lagu helaa nadiifinta vacuum.

6. Dareen-celinta methylation ee aniline iyo trimethyl phosphate waxay soo saari karaan N, N-dimethylaniline: ka dibna la soo saaro ether, qallajinta qalalan.

7. N, N-dimethylaniline waxaa lagu soo saari karaa isku dar ah aniline iyo methanol ee saamiga 1∶ 3.5 ee sariirta catalytic ee Cu-Mn ama Cu-Zn-Cr Ziegler kicinta 280 ℃. Natiijadii N, N-dimethylaniline waxaa lagu soo ururiyay unugga nadiifinta ee 54 taarikada inta u dhaxaysa 193 ilaa 195 ℃ waxaana lagu shubay dhalooyin dhalada bunni ah. Diyaarinta chromatography saafi ah N, N-dimethylaniline, nitrogen waxay noqon kartaa gaaska side, diyaarinta chromatography gaaska oo leh tiirarka Ben 犅 yaku ayaa lagu duray hagaajinta N, N-dimethylaniline, iyada oo loo marayo kala-soocidda iyo ururinta qaybta ugu sarreysa ee qaybta ugu sarreysa, ka dibna galay shaabadda ampoule galaas noqon kartaa.
