Nhanganyaya

Dimethyl sulfide (inozivikanwawo se dimethyl sulfide) is anorganic sulfur compound. Iyi inotevera sumo kune zvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza dimethyl sulfide:

 

Hunhu:

- Chitarisiko: Mvura isina ruvara ine kunhuhwirira kwakakosha.

- Solubility: kusanganiswa ne ethanol, ethers, uye akawanda organic solvents.

 

Shandisa:

- Maindasitiri ekushandisa: Dimethyl sulfide inoshandiswa zvakanyanya se solvent mune organic synthesis reactions, kunyanya mu sulfidation uye thioaddition reactions.

 

Nzira:

- Dimethyl sulfide inogona kugadzirirwa nekuita kwakananga kwe ethanol uye sulfur. Mhedzisiro yacho inowanzoitika pasi pemamiriro e acidic uye inoda kudziyisa.

- Inogonawo kugadzirwa nekuwedzera sodium sulfide kune maviri methyl bromides (semuenzaniso methyl bromide).

 

Zvekuchengetedza

- Dimethyl sulfide ine kunhuhwirira kwakashata uye ine mhedzisiro inogumbura paganda nemeso.

- Dzivisa kusangana neganda nemeso uye tora matanho akakodzera paunenge uchishandisa.

- Panguva yekushandiswa nekuchengetedza, kusangana neoxidants uye yakasimba acids kunofanirwa kudziviswa kudzivirira kuita kusina kuchengeteka.

- Tsvina inofanira kuraswa zvichitevedza mitemo nemirau yenzvimbo uye haifanirwe kuraswa.

- Chengetedza mhepo yakakodzera panguva yekuchengetedza uye kushandiswa.
