Ngokwendlela ebonakalayo ebonakalayo, ikakhulukazi:

1) indlela ye-aniline;

2) o - i-nitrofenyl chloride indlela;

3) n - indlela ye-methylaniline;

4) n, n - dimethylformamide indlela;

5) Indlela E-Dimethyyamine;

6) indlela ye-haloaniline;

7) Indlela yeBenzothiazole;

8) o - i-chlorothiophenol indlela;

9) Indlela yeNitrobenene nokunye okunjalo.

Inqubo ethile ye-synthesis ye-accelerator ye-accelerator ye-rubber Vulcanization M yilena: i-aniline, i-CS2, i-benzothiazole yengezwa, ngemuva kokuphendula kuqediwe, ngemuva kokuthi ukusabela kuqediwe i-H2S ye-H2S kanye ne-CS2 ye-SULFUR kanye ne Iyunithi yokuvuselela i-CS2. I-molton m ingena ethangi lokuchithwa futhi ichithwe ngesisombululo sooh, futhi udaba lokungena ngaphakathi lususwa ngokuhlunga. I-filtrate yakhishwa ngoToluneenee ukululama ngo-- Ungqimba lweToluene ungena kwinqubo yokubuyiselwa kwe-solvent ukuthola kabusha i-benzene. Isendlalelo samanzi siyisixazululo sikasawoti se-m sodium. Ngokwezidingo zemikhiqizo ephansi ye-MOWSTRIVEM, ingasetshenziswa ngokuqondile ngemuva kokuhlushwa, futhi nayo ingahle i-acid yi-acid, bese yomiswa ukuthola i-crystal M.

Izindlela Zokunciphisa Izindleko:

The nge - Umkhiqizo weBenzothiazole wabuyiselwa emkhunjini wokuphendula. Owokuqala ukucwilisa i- -}, khipha i-benzothiazole umkhiqizo -, bese uyibuyisela kwi-reaction. Okwesibili ukusebenzisa i-solvent ukuthola i-crude ecwengekile ye-m, ukugwema ukusetshenziswa okungadingekile kwenqubo yokucwengwa kwamakhemikhali, nokuhlinzeka ngenqubo elula nengenzeka kokukhiqizwa kwezimboni. The nge - I-Tar Product Park inqubo yokukhiqiza ye-M yiyona iningi le-benzothiazole, lilandelwa yi-aniline, i-thiresordiulea nokunye okunjalo. Ngokusho kwezincwadi, uBenzothiazole ungumkhiqizo ophakathi nendawo kaM. Benzothazole ne-thoiresorthene bangakha m ngokungezelela ama-S ne-CS2 / s.

Ukucolisiswa kwengxube yokusabela:

Ukukhishwa kwe-solvent kusetshenziselwa ukululama ngo- - Umkhiqizo we-benzothiazole futhi ucwenge usawoti we-so sodium. I-solvent esetshenzisiwe ingaba: monochlororenenene, o {{- UDicchoronenzene, Toluene, Benzezene, CS2 nePolychlororoethane.

Ukukhishwa:

Ngesikhathi sokukhishwa, i-crude m yayingezelelwa kancane emanzini ashisayo, ivuse ngamandla phambi kwe-survides, khona-ke i-organic solvent yangezwa, futhi kwaqhutshwa i-solvent ye-organic, futhi kwaqhutshwa i-solvent e-emulsation kuze kube yilapho amazinga okushisa afike ku-170 degree.

Ama-surfactants angama-sodium dodecylenEsulfonate, i-sodium nonylbezesesulfonate, ammonium dibutydodecylenlenlenlenlenlenlenlenlenlenlenlenlenlenlenlenlenleslenlenlenlenlenEsulfonate, usawoti wensimbi we-alkali wotshwala obunamafutha obunamafutha, i-alkali yensimbi yensimbi, nokunye okunjalo. Lapho kusetshenziswa i-ionic sursuctant, ngemuva kokukhishwa, ingxenye yokuqala yesisombululo ihlungiwe futhi i-acid ku-pH ka-3-4.

Indlela ye-aniline isuselwa ku-aniline, CS2 naseS. Kusukela i-CS2 ingamakhemikhali anobungozi obuvuthayo futhi aqhumayo, awuphatheki kahle ukusebenzisa. Le nkampani ibike ukusetshenziswa kwe-aniline, n, n '- dimethylformamide kanye no-S. Inqubo yokukhiqiza ye-syntherator ye-accelerator m njengento eluhlaza. Ukushisa okusheshayo kungama-200- 300℃C, izinga lokushisa elilungile lingu-225-275℃C, ingcindezi yi-3.45-4.83 MPA (Ingcindezelo yendlela icishe ibe ngu-12 h, kepha isikhathi sokuphendula sisezingeni eliphansi, kuphela ama-66%.
