Mawu Oyamba
Methylphenyl disulfide (yomwe imadziwikanso kuti methyldiphenyl disulfide) ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha methylphenyl disulfide:
Ubwino:
- Maonekedwe: Madzi opanda mtundu mpaka owala achikasu
- Kununkhira: Pamakhala fungo lachilendo la sulfide
- Flash Point: Pafupifupi 95°C
- Kusungunuka: Kusungunuka mu zosungunulira organic monga ethanol ndi dimethylformamide
Gwiritsani ntchito:
- Methylphenyl disulfide imagwiritsidwa ntchito ngati vulcanization accelerator ndi crosslinker.
- Amagwiritsidwa ntchito kwambiri pamakampani opanga mphira chifukwa cha vulcanization ya mphira, yomwe imatha kusintha kukana kwa mphira, kukana kutentha ndi thupi komanso makina a rabara.
- Methylphenyl disulfide itha kugwiritsidwanso ntchito popanga mankhwala monga utoto ndi mankhwala ophera tizilombo.
Njira:
Methylphenyl disulfide ikhoza kukonzedwa ndi zomwe diphenyl ether ndi mercaptan zimachita. Njira yeniyeni ndi iyi:
1. M'mlengalenga, diphenyl ether ndi mercaptan amawonjezedwa pang'onopang'ono ku reactor pa mlingo woyenera wa molar.
2. Onjezani acidic catalyst (mwachitsanzo, trifluoroacetic acid) kuti muthandizire kuchitapo kanthu. Kutentha kwazomwe zimachitika nthawi zambiri kumayendetsedwa ndi kutentha kwa chipinda kapena kutentha pang'ono.
3. Pambuyo pa kutha kwa zomwe zimachitika, mankhwala omwe amafunidwa a methylphenyl disulfide amasiyanitsidwa ndi distillation ndi kuyeretsedwa.
Zambiri Zachitetezo:
- Methylphenyl disulfide ndi organic sulfide yomwe ingayambitse kupsa mtima komanso kawopsedwe m'thupi la munthu.
- Valani magolovesi oteteza, magalasi, ndi zotchingira gasi pogwira ntchito kuti musakhumane ndi khungu komanso pokoka mpweya.
- Pewani kukhudzana ndi ma oxidizing amphamvu ndi ma acid kuti mupewe zoopsa.
- Khalani kutali ndi magwero oyatsira kuti mupewe zosakhazikika.
- Tsatirani kasungidwe koyenera ndi kasamalidwe kuti mupewe ngozi.
