Izakhiwo Zomzimba Nezamakhemikhali Uketshezi olungenambala. Iphoyinti elibilayo 169-171 ℃,61 ℃(1.33kPa). Indlela Yokulungiselela: Isixazululo se-sodium methyl mercaptan-anhydrous ethanol sishiselwa ukuba sibile, ukushisisa kuyamiswa, bese i-chloroethanol yengezwa ngokudonsa ngaphansi kokunyakaziswa ngaphakathi kuka-2H. Ingxube yokusabela yagxiliswa, yavunyelwa ukuba imele ukupholisa, futhi i-sodium chloride yahlungwa. I-filtrate yahlukaniswa ngaphansi kwengcindezi encishisiwe yokuqoqa ingxenyenamba engu-68-70 ° C. (2.67kPa) ukuze kutholwe i-2-methylthioethanol ngesivuno esingu-74% -82%. Izinjongo: Okumaphakathi ku-organic synthesis.

Isingeniso

I-2-Methylthioethanol, eyaziwa nangokuthi i-2-methylthioethanol, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-2-Methylthioethanol iwuketshezi olungenambala ukuya kokuphuzi okukhanyayo.

- Iphunga: Inephunga elinamandla le-hydrogen sulfide.

- Ukunyibilika: Kuncibilika emanzini nakwezinye izincibilikisi zemvelo ezifana notshwala nama-ether.

- Izakhiwo: Izwela emoyeni futhi ingafakwa i-oxidized ukuze i-disulfide, okulula ukubangela ukuvutha.

 

Sebenzisa:

- I-Chemical synthesis: I-2-methylthioethanol ingasetshenziswa njengendawo ephakathi ku-organic synthesis.

- Umuthi wokuhlanza: Ungasetshenziswa njenge-surfactant kanye ne-detergent ekulungiseleleni okokuhlanza.

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

 

Indlela:

I-2-Methylthioethanol ingalungiswa ngu:

I-Thioethanol yakhiwa ngokusabela nge-methyl chloride.

I-Ethiohydrazine yakhiwa ngokusabela nge-ethanol.

 

Ulwazi Lokuphepha:

- 2-Methylthioethanol inephunga elimnandi futhi ingabangela ukucasuka kwamehlo nesikhumba uma ithintwa.

- Uma uhogela, kungabangela ukucasuka kokuphefumula kanye nokungakhululeki kwesifuba.

- Ukugwinya noma ukudla amanani amakhulu kungase kubangele ubuthi, kubangele ukuphazamiseka emathunjini.

- Gqoka izinto zokuzivikela ezifanele ezifana namagilavu ​​nezibuko zokuphepha lapho usebenzisa.

- Uma usebenza, gwema amalangabi avulekile nezindawo ezinezinga lokushisa eliphezulu ukuze ugweme ukubangela ukusha.
