Hordhac

Dimethyl sulfide (sidoo kale loo yaqaan dimethyl sulfide) waa iskudhis baaruud ah. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada dimethyl sulfide:

 

Tayada:

- Muuqashada: dareere aan midab lahayn oo leh ur gaar ah oo xooggan.

- Solubility: waxaa lagu khaldi karaa ethanol, ethers, iyo dareerayaal badan oo organic ah.

 

Isticmaal:

Codsiyada warshadaha: Dimethyl sulfide waxaa si weyn loogu isticmaalaa sida dareere ee falcelinta synthesis organic, gaar ahaan sulfidation iyo falcelinta thioaddition.

 

Habka:

- Dimethyl sulfide waxaa lagu diyaarin karaa falcelinta tooska ah ee ethanol iyo baaruud. Dareen-celinta badanaa waxay ku dhacdaa xaaladaha acidic waxayna u baahan tahay kuleyl.

Waxa kale oo lagu diyaarin karaa in lagu daro sodium sulfide laba methyl bromide (tusaale methyl bromide).

 

Macluumaadka Badbaadada:

- Dimethyl sulfide waxay leedahay ur ur xun waxayna saameyn xun ku leedahay maqaarka iyo indhaha.

- Ka fogow taabashada maqaarka iyo indhaha oo qaado taxadar ku habboon markaad isticmaalayso.

- Inta lagu jiro isticmaalka iyo kaydinta, xidhiidhka oksidants iyo acids xooggan waa in laga fogaadaa si looga fogaado falcelin aan ammaan ahayn.

- Waa in qashinka lagu guraa si waafaqsan shuruucda iyo xeerarka deegaanka oo aan la daadin.

- Ilaali hawo sax ah inta lagu jiro kaydinta iyo isticmaalka.
