I-Dimethyl Sulfide (I-CAS: 624-92) Ulwazi (i-CAS: 624-92-0)

1.Iipropathi zeekhemikhali:

Ukukhanya kwetyheli etyheli. Kukho ivumba elingcolileyo. Inganyibiliki emanzini kwaye ingadityaniswa ne-ethanol, i-ether, kunye ne-acetic acid.

2.Purive:

Isetyenziswe njengearhente edlulayo, i-catalysts, i-petaterider ephakathi, i-Coiking ethintela, njl njl. Esi sisiseko se-phosphori of phosphorus ye-phosphorius ene-phosserius ye-phosseckisius phossectide enezixhobo ezifanelekileyo zokulawula iirayisi, iintliziyo zesoya, kunye ne-gadfly grue. Ingasetyenziswa njengeyeza lezilwanyana lokuphelisa iimpethu kunye neentwala zenkomo.

3. Indlela yokuvelisa:

I-①I ifunyanwa yindlela yokuphendula ye-dimthyl sulfate kunye nesodium sulfide. Yongeza i-sulfur powder kwisisombululo seSodium Sulfiide phantsi kokuvuselela i-80-90 ℃, iphendule i-1h, kwaye inciphise iqondo lekhemi lekhemikhali malunga ne-30 ℃; I-Dimethyl Sulfate iphoswe kwi-ketete yesabelo, impendulo iyaqhubeka kwe-2h, kwaye ilusizi, ukuma. Emva kokwahlula utywala i-alkali yenkunkuma, imveliso egqityiweyo ifunyanwa ngokudibana.

I-②dimethyl

I-na2s + s → i-na2S22s2 + (Ch3) 2SO4 → I-Ch3SSCH3 + NA20

Beka i-sodium ye-sodium kunye namanzi kwi-ketete yesakhiwo, tshisa, ulawule i-Stradebo ye-Sulfur Sulfure, gcina i-1h, gcina i-1h, iqhubeke ifudumele i-1h emva kongeziweyo, emva koko ikhuphe i Imveliso ye-dimthyl Ukongeza, ukuhenyuza kwe-dimethyl kungakwazi ukuhlelwa yiMethyl Mermentary ndlela.

I-③IT iveliswa yindlela yokusabela ye-I-I-I-I-I-I-I-I-I-I-I-I-Insomethyl magnesium kunye nokudubula i-dichloride. Yenziwa yindlela yokuphendula ye-sodium I-methyl sodium thiouium ilungiselelwe ngokusabela ngokuphendula i-bromomethane ene-sodium ye-sodium bioulfate, emva koko ishushu.

 

I-4.Ststorage kunye neempawu zothutho:

Umoya ovuthuzayo kunye nobushushu obuphantsi bokusola kwendawo yokugcina izinto; Gcina ngokwahlukeneyo kwii-oxidants kunye ne-acids

 

5.Ukucima umlilo

I-powder eyomileyo, isanti eyomileyo, i-carbon diokside, i-foam, i-1211 yokucima iarhente
