| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. U-R10 – Uyavutha |
| Incazelo Yokuphepha | I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S16 – Zigcine kude nemithombo yokuthungela. |
| Ikhodi ye-HS | 29309099 |
Isingeniso
I-Methylphenyl disulfide (eyaziwa nangokuthi i-methyldiphenyl disulfide) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-methylphenyl disulfide:
Ikhwalithi:
- Ukubukeka: Uketshezi olungenambala oluphuzi olukhanyayo
- Iphunga: Kukhona iphunga le-sulfide elingavamile
- Flash Point: Cishe 95°C
- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo njenge-ethanol ne-dimethylformamide
Sebenzisa:
- I-Methylphenyl disulfide ivame ukusetshenziswa njenge-vulcanization accelerator kanye ne-crosslinker.
- Ivame ukusetshenziswa embonini yenjoloba ngokusabela kwe-vulcanization yenjoloba, engathuthukisa ukumelana nokugqoka, ukumelana nokushisa kanye nezakhiwo zomzimba nemishini yerabha.
- I-Methylphenyl disulfide ingasetshenziswa futhi ekulungiseni amakhemikhali afana nodayi nezibulala-zinambuzane.
Indlela:
I-Methylphenyl disulfide ingalungiswa ngokusabela kwe-diphenyl ether ne-mercaptan. Inqubo ethize imi kanje:
1. Emkhathini ongasebenzi, i-diphenyl ether ne-mercaptan zengezwa kancane ku-reactor ngesilinganiso esifanele se-molar.
2. Engeza i-acidic catalyst (isb, i-trifluoroacetic acid) ukusiza ukusabela. Izinga lokushisa lokusabela ngokuvamile lilawulwa ekamelweni lokushisa noma izinga lokushisa eliphakeme kancane.
3. Ngemva kokuphela kokusabela, umkhiqizo owufunayo we-methylphenyl disulfide uhlukaniswa yi-distillation nokuhlanza.
Ulwazi Lokuphepha:
- I-Methylphenyl disulfide iyi-sulfide ephilayo engase ibangele ukucasuka okuthile kanye nobuthi emzimbeni womuntu.
- Gqoka amagilavu okuvikela afanele, izibuko, kanye nezindawo zokufihla ubuso lapho usebenza ukuze ugweme ukuthintana nesikhumba kanye nokuhogela amagesi.
- Gwema ukuthintana nama-oxidizing aqinile nama-acids ukugwema ukusabela okuyingozi.
- Gcina kude nemithombo yokuthungela ukuze ugweme izinhlansi ezimile.
- Landela imikhuba efanele yokugcina nokuphatha ukuze ugweme izingozi.
