Gusobanura:

Dushingiye ku nzira y’ibintu bitagira agaciro, ahanini ni:

1) Uburyo bw’ibikoko;

2) o- uburyo bwa chloride chloride;

3) N- uburyo bw'umurongo;

4) N,N- uburyo bwo gufata dimethylformamide;

5) uburyo bwa dimethylamine;

6) uburyo bwa haloaniline;

7) uburyo bwa benzothiazole;

8) o- Uburyo bwo gukoresha chlorothiophophenol;

9) Uburyo bwa Nitrobenzene n’ibindi nk’ivyo.

Uburyo bwihariye bwo gukora umuyagankuba w’umupira M ni: ikibiriti gipfutse, aniline, CS2, benzothiazole yongewe ku nzira y’umuvuduko munini n’ugutera imbere, ubushuhe bw’inyishu ni 250℃C, umukazo ni 5.87 MPa, inyuma y’aho inyishu irangiye, igipimo c’umuvuduko w’amazi igice ca gazi Igice ca H2S cavuwe n’inzira ya CS2 itagira ubushobozi igice n’igice ca CS2. Ico gikoresho M cinjira mu gitereko c’ugusesagura maze kigaca gipfukwa n’umuti wa NaOH, kandi ikintu kidahumanye gikurwaho biciye mu kuyungurura. Ivyo bikoresho vyakuwemwo toluene kugira ngo bishobore gukira biciye ku - y’ibintu n’ibindi bikoresho. Igipande c’ivyuma vy’amazi cinjira mu nzira yo gusubirana kw’ibintu kugira ngo umuntu akire benzene. Igipande c’amazi ni umuti w’umunyu wa M sodium. Dushingiye ku nkenegwa z’ibintu biva mu ruzi M, birashobora gukoreshwa ata guca ku ruhande inyuma y’ugushiramwo, kandi bishobora no guterwa n’aside, hanyuma bikayuma kugira ngo bironke ikiririmbo cumye M.

Inzira zo kugabanya ibiciro:

Ico gikoresho ca benzothiazole c’umurimo carasubijwe mu bwato bwo gusubiza. Ica mbere ni ugutunganya igicapo c’ibintu vy’umurimo, gukuramwo benzothiazole ku -, hanyuma: kugisubiza ku gikoresho co gukora. Ica kabiri ni ugukoresha umuti kugira ngo umuntu asubize Mperide M, kwirinda gukoresha nabi uburyo bwo gutunganya imiti, no gutanga uburyo bworoshe kandi bushoboka bwo guhingura inganda. Igitabu c’ibintu vy’umubiri mu nzira y’uguhingura M ni ahanini benzothiazole, hanyuma hakurikirwa n’indwara ya aniline, thioresordiurea n’ibindi nk’ivyo. Dushingiye ku bitabu, benzothiazole ni ikintu kiri hagati ya M. Benzothiazole na thionsorthene gishobora gukora M mu kwongerako S na CS2/S.

Gusobanura uruvange rw'ivyo bisubizo:

Gukuramwo umunyu bikoreshwa mu gusubizaho umunyu w’umunyu w’umukara no kugira ngo utunganye umunyu wa M sodium. Ico gikoresho gikoreshwa gishobora kuba: monochrobenzene, o{2}}dichlobonzene, toluene, benzene, CS2 na polychloroetatne.

gukuramwo:

Mu gihe c'ivyo gukurako, iyo Mpen M yarongerewe buhoro buhoro ku mazi ashushe, ivyura umutima cane iyo hariho ikintu co gutera sukari, hanyuma hashirwako umunyu w'ibinyabuzima, maze hakomezwa mu gihe ubushuhe bwashitse ku 170℃.

Ivyo bihimba vy’umubiri ni sodium dodecylbenzenesulfonate, sodium atari mulbenzenesulfonate, umunyu w’ivyuma vy’i alkali, umunyu w’ivyuma vy’i alkali w’inzoga y’agaciro, isabune y’icuma c’i alkali, n’ibindi nk’ivyo. Iyo hakoreshejwe umuti w’iyon, inyuma yo gukura, igice ca mbere c’umuti kiracungururwa maze kigaterwa n’aside ku pH ya 3-4.

Uburyo bwa aniline bushingiye kuri aniline, CS2 na S. Kubera ko CS2 ari umuti ushobora gushavura kandi ushobora guturika, ntibukwiye cane gukoreshwa. Iryo shirahamwe ryatangaje ko rikoresha aniline, N, N’-dimethylformmide na S. Inzira y’uguhingura kw’ivyuma vy’ivyuma vy’ivyuma M nk’ibikoresho vya mbere. Ubushuhe bw’inyishu ni 200-300℃C, ubushuhe bwiza bwo gusubiza ni 225-275℃C, umuvuduko ni 3.45-4.83 MPa (umuvuduko w’igipimo), kandi igihe co gusubiza ni nk’amasaha 12, ariko umwimbu w’uburyo ni muto cane, 66% gusa.

Imisoro ishushe: Igikoresho co gutera umutsi mu gipimo, Ubushinwa, umuhinguzi, abagurisha, uruganda, igiciro, umubumbe w’imipira, umuti w’imipira, uteguwe .
