Intshayelelo
I-Methylphenyl disulfide (eyaziwa ngokuba yi-methyldiphenyl disulfide) yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methylphenyl disulfide:
Umgangatho:
- Imbonakalo: Ayinabala ukuya kulwelo olutyheli olukhanyayo
- Ivumba: Kukho ivumba elikhethekileyo lesulfide
-Indawo edanyazayo: Malunga ne-95°C
- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-dimethylformamide
Sebenzisa:
- I-Methylphenyl disulfide isetyenziswa ngokuqhelekileyo njenge-vulcanization accelerator kunye ne-crosslinker.
- Isetyenziswa ngokuqhelekileyo kwishishini lerabha kwi-vulcanization reaction yerabha, enokuphucula ukunyanzeliswa kokugqoka, ukuxhathisa ukushisa kunye neempawu zomzimba kunye nemishini yerabha.
- I-Methylphenyl disulfide ingasetyenziselwa ukulungiswa kweekhemikhali ezifana nedayi kunye nezitshabalalisi.
Indlela:
I-Methylphenyl disulfide inokulungiswa ngokusabela kwe-diphenyl ether kunye ne-mercaptan. Inkqubo ethile imi ngolu hlobo lulandelayo:
1. Kwi-atmosphere engasebenzi, i-diphenyl ether kunye ne-mercaptan zongezwa ngokucothayo kwi-reactor kwi-molar ratio efanelekileyo.
2. Yongeza i-acidic catalyst (umzekelo, i-trifluoroacetic acid) ukuququzelela ukusabela. Ubushushu bokusabela bulawulwa ngokubanzi kwiqondo lobushushu begumbi okanye ubushushu obuphezulu kancinane.
3. Emva kokuphela kokusabela, imveliso efunwayo ye-methylphenyl disulfide ihlukaniswe yi-distillation kunye nokucoca.
Ulwazi ngoKhuseleko:
I-Methylphenyl disulfide yi-sulfide ephilayo enokubangela ukucaphuka kunye netyhefu emzimbeni womntu.
-Nxiba iiglavu ezifanelekileyo zokukhusela, iiglasi, kunye neemaski zegesi xa usebenza ukunqanda ukudibana nolusu kunye nokuphefumla iigesi.
- Kulumkele ukudibana neearhente ezinamandla ze-oxidizing kunye neeasidi ukuphepha ukuphendula okuyingozi.
- Gcina kude kwimithombo yomlilo ukunqanda iintlantsi ezimileyo.
- Landela iindlela ezifanelekileyo zokugcina kunye nokuphatha ukuphepha iingozi.
