Selelekela
Methylphenyl disulfide (eo hape e tsejoang e le methyldiphenyl disulfide) ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea methylphenyl disulfide:
Boleng:
- Ponahalo: Mokelikeli o se nang 'mala ho isa ho o mosehla o khanyang
- Monko: Ho na le monko o ikhethang oa sulfide
- Flash Point: Hoo e ka bang 95°C
- Ho qhibiliha: Ho qhibiliha ka har'a lihlapolli tsa tlhaho tse kang ethanol le dimethylformamide
Sebelisa:
- Methylphenyl disulfide hangata e sebelisoa e le vulcanization accelerator le crosslinker.
- E atisa ho sebelisoa indastering ea rabara bakeng sa karabelo ea vulcanization ea rabara, e ka ntlafatsang ho hanyetsa ho apara, ho hanyetsa mocheso le thepa ea 'mele le ea mechine ea rabara.
- Methylphenyl disulfide e ka boela ea sebelisoa ho lokisa lik'hemik'hale tse kang dae le chefo e bolaeang likokoanyana.
Mokhoa:
Methylphenyl disulfide e ka lokisoa ka karabelo ea diphenyl ether le mercaptan. Mokhoa o khethehileng ke o latelang:
1. Sebakeng se sa sebetseng, diphenyl ether le mercaptan li kenngoa butle-butle ho reactor ka tekanyo e nepahetseng ea molar.
2. Eketsa motsoako oa acidic (mohlala, trifluoroacetic acid) ho thusa ho arabela. Mocheso oa karabelo hangata o laoloa ka mocheso oa kamore kapa mocheso o phahameng hanyane.
3. Kamora ho fela ha karabelo, sehlahisoa se lakatsehang sa methylphenyl disulfide se arohanngoa ke distillation le tlhoekiso.
Lintlha tsa Tšireletseho:
- Methylphenyl disulfide ke sulfide ea tlhaho e ka bakang ho teneha le chefo 'meleng oa motho.
- Apara liatlana tse sireletsang, likhalase le limaske tsa khase ha u sebetsa ho qoba ho kopana le letlalo le ho hema likhase.
- Qoba ho kopana le li-oxidizing tse matla le li-acids ho qoba liketso tse kotsi.
- Qoba hole le mehloli e tukang ho qoba litlhase tse sa fetoheng.
- Latela mekhoa e nepahetseng ea ho boloka le ho tšoara ho qoba likotsi.
