IiPropati zoMzimba kunye nezeMichiza Ulwelo olungenambala. Indawo yokubilisa 169-171 ℃,61 ℃(1.33kPa). Indlela yokuLungisa: Isisombululo se-sodium methyl mercaptan-anhydrous ethanol sifudunyezwa ukubilisa, ukufudumeza kumisiwe, kwaye i-chloroethanol yongezwa i-dropwise phantsi kokuvuselela ngaphakathi kwe-2H. Umxube wokuphendula wawugxininiswe, uvunyelwe ukuba ume ukupholisa, kwaye i-sodium chloride yahluzwa. I-filtrate yahlulwa phantsi koxinzelelo oluncitshisiweyo lokuqokelela i-68-70 ° C. (2.67kPa) iqhekeza ukufumana i-2-methylthioethanol kwisivuno se-74% -82%. Iinjongo: abaphakathi kwi-organic synthesis.

Intshayelelo

I-2-Methylthioethanol, eyaziwa ngokuba yi-2-methylthioethanol, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: 2-Methylthioethanol lulwelo olungenambala ukuya kokukhanya tyheli.

- Ivumba: Inevumba elinamandla lehydrogen sulfide.

- Ukunyibilika: Ukunyibilika emanzini kunye nezinye izinyibilikisi eziphilayo ezifana neealkoholi kunye neetha.

- Iipropathi: Inochuku kumoya kwaye inokuthi ifakwe i-oxidized kwi-disulfide, elula ukubangela ukutshisa.

 

Sebenzisa:

- I-Chemical synthesis: I-2-methylthioethanol ingasetyenziselwa njengendawo ephakathi kwi-organic synthesis.

- I-detergent: Ingasetyenziswa njenge-surfactant kunye ne-detergent ekulungiseleleni izinto zokucoca.

- I-Alcohol flame retardant: I-2-methylthioethanol ingasetyenziswa njenge-alcohol flame retardant.

 

Indlela:

I-2-Methylthioethanol inokulungiswa ngolu hlobo:

- I-Thioethanol yenziwa ngokusabela nge-methyl chloride.

- I-Ethiohydrazine yenziwa ngokusabela nge-ethanol.

 

Ulwazi ngoKhuseleko:

I-2-Methylthioethanol inevumba elibi kwaye inokubangela ukucaphuka kwamehlo kunye nolusu xa iphathwa.

- Xa uphefumla, kunokubangela ukucaphuka kokuphefumula kunye nokukhathazeka kwesifuba.

- Ukuginya okanye ukuginya izixa ezikhulu kunokubangela ityhefu, kubangele ukuphazamiseka kwesisu.

- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu kunye neeglasi zokhuseleko xa usebenzisa.

- Xa usebenza, gcina kude namadangatye avulekileyo kunye neendawo ezinobushushu obuphezulu ukuze ugweme ukutshisa.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
