Okusinziira ku kkubo ly’ebintu ebisookerwako, okusinga waliwo:

1) enkola ya aniline;

2) O-Enkola ya Nitrophenyl chloride;

3) N-Enkola ya methylaniline;

4) N,N-Enkola ya dimethylformamide;

5) enkola ya dimethylamine;

6) enkola ya haloaniline;

7) enkola ya benzothiazole;

8) O-Enkola ya chlorothiophenol;

9) Enkola ya nitrobenzene n’ebirala ebiringa ebyo.

The specific synthesis process of the rubber vulcanization accelerator M is: molten sulfur, aniline, CS2, benzothiazole is added to the high pressure reaction kettle with stirring, the reaction temperature is 250℃C, the pressure is 5.87 MPa, after the reaction is finished, the pressure is released, the gas phase Part of the generated H2S and unreacted CS2 enter the sulfur recovery unit and the CS2 Ekitundu ky’okuzzaawo. M esaanuuse eyingira mu ttanka y’okusaanuuka n’esaanuuka n’ekisengejjero kya NaOH, era ekintu ekitasaanuuka ne kiggyibwawo nga kisengejja. Ekisengejjeddwa kyaggyibwamu ne toluene okuwona nga-product benzothiazole ne ttaala endala. Layer ya toluene eyingira mu nkola y’okuzzaawo solvent okuzzaawo benzene. Olususu lw’amazzi lulimu omunnyo gwa M sodium. Okusinziira ku byetaago by’ebintu ebiva mu m wansi w’omugga, esobola okukozesebwa butereevu oluvannyuma lw’okusengejja, era esobola n’okufuulibwa asidi mu asidi, n’oluvannyuma n’ekalira okufuna Crystal M enkalu.

Engeri y’okukendeeza ku nsaasaanya:

The by-ekintu benzothiazole kyaddizibwa mu kibya ky’okuddamu. Ekisooka kwe kulongoosa nga-product tar, okuggyamu benzothiazole nga-ekivaamu, n’oluvannyuma: kizzeeyo mu riyakita. Ekyokubiri kwe kukozesa ekizimbulukusa okuzzaawo omulongoofu ogulongooseddwa M, okwewala okukozesa enkola y’okulongoosa eddagala mu ngeri eteetaagisa, n’okuwa enkola ennyangu era esoboka okukola mu makolero. The by-Product Tar mu nkola y’okufulumya M esinga kuba benzothiazole, nga egobererwa aniline, thioresordiurea n’ebirala ebiringa ebyo. Okusinziira ku biwandiiko, benzothiazole kiva mu kitundu eky’omu makkati ekya M. benzothiazole ne thioresorthene kisobola okukola M nga kigatta S ne CS2/S.

Okulongoosa omutabula gw’ensengekera:

Okuggyamu ekizimbulukusa kukozesebwa okuzzaawo -product benzothiazole n’okulongoosa omunnyo gwa M sodium. Ekizimbulukusa ekikozesebwa kiyinza okuba: monochlorobenzene, o-dichlorobenzene, toluene, benzene, CS2 ne polychloroethane.

Okuggyamu:

Mu kiseera ky’okuggyamu, M omubisi gwateekebwa mpola mu mazzi agookya, ne gasiikulwa n’amaanyi nga waliwo ekirungo ekikola ku ttaka, oluvannyuma ne kigattibwamu ekizimbulukusa ekiramu, era okutabula kwagenda mu maaso mu mbeera y’okufuuka emulsification okutuusa ebbugumu lwe lyatuuka ku diguli 170 .

Ebirungo ebikola ku ttaka bye bino: sodium dodecylbenzenenesulfonate, sodium nonylbenzenesulfonate, ammonium dibutyldodecylbenzenenesulfonate, omunnyo gw’ekyuma kya alkali ogw’omwenge ogw’amasavu ogulimu sulfonated, ssabbuuni w’ekyuma kya alkali n’ebirala ebiringa ebyo. Ekirungo ekikola ku ngulu (ionic surfactant) bwe kikozesebwa, oluvannyuma lw’okuggyamu, ekitundu ekisooka eky’ekisengejjero kisengejebwa ne kifuulibwa asidi okutuuka ku pH ya 3-4.

Enkola ya aniline yeesigamiziddwa ku aniline, CS2 ne S. Okuva CS2 bwe kiri eddagala erikwata omuliro era ery’obulabe eritulika, tekiba kyangu nnyo okukozesa. Kampuni etegeezezza nti enkozesa ya aniline, n, n’-dimethylformamide ne S. Enkola y’okufulumya eky’okusengejja M ng’ekintu ekibisi. Ebbugumu ly’ensengekera liri 200-300℃C, ebbugumu ly’ensengekera erisinga obulungi liri 225-275℃C, puleesa eri 3.45-4.83 MPa (puleesa ya gauge), ate obudde bw’ensengekera buba nga 12 h, naye amakungula g’enkola eno ga wansi nnyo, 66% zokka.
