Methyl phenyl disulfide (CAS#14173-25-2)

Nhanganyaya

Methylphenyl disulfide (inozivikanwawo semethyldiphenyl disulfide) isanganiswa yeorganic. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza yemethylphenyl disulfide:

Hunhu:

- Chitarisiko: isina ruvara kune yakareruka yero mvura

- Kunhuwa: Pane kunhuhwirira kwe sulfide

- Flash Point: Inenge 95°C

- Solubility: Soluble mu organic solvents senge ethanol uye dimethylformamide

Shandisa:

-Methylphenyl disulfide inowanzoshandiswa sevulcanization accelerator uye crosslinker.

-Inowanzo shandiswa muindasitiri yerabha kune vulcanization reaction yerabha, iyo inogona kuvandudza kupfeka kuramba, kupisa kupisa uye zvemuviri uye zvemagetsi zvimiro zverabha.

- Methylphenyl disulfide inogona zvakare kushandiswa mukugadzirira kwemakemikari akadai sedhayi nemishonga yezvipembenene.

Nzira:

Methylphenyl disulfide inogona kugadzirirwa nekuita kwe diphenyl ether uye mercaptan. Iyo chaiyo process ndeiyi inotevera:

1. Mumhepo inert, diphenyl ether uye mercaptan zvinowedzerwa zvishoma nezvishoma kune reactor pane zvakakodzera molar ratio.

2. Wedzerai acidic catalyst (semuenzaniso, trifluoroacetic acid) kuti ifambise maitiro. The reaction tembiricha kazhinji inodzorwa pakamuri tembiricha kana tembiricha yakakwira zvishoma.

3. Mushure mekuguma kwekuita, methylphenyl disulfide inodiwa inoparadzaniswa ne distillation uye kucheneswa.

Zvekuchengetedza

-Methylphenyl disulfide ndeye organic sulfide iyo inogona kukonzera kumwe kutsamwa uye chepfu kumuviri wemunhu.

- Pfeka magirovhosi ekudzivirira akakodzera, magirazi uye masks egasi paunenge uchishanda kudzivirira kusangana neganda uye inhalation yemagasi.

-Dzivisa kusangana neakasimba oxidizing agents uye maasidhi kudzivirira kuita zvine njodzi.

- Chengetedza kure nezvinobatidza moto kuti udzivise static sparks.

- Tevedzera kwakaringana kuchengetedza uye kubata maitiro kudzivirira tsaona.
