Isingeniso

I-3-mercapto-2-butanone, eyaziwa nangokuthi i-2-butanone-3-mercaptoketone noma i-MTK, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala noma ikristalu emhlophe

- Ukunyibilika: Kuncibilika ku-ethanol, ether nase-chloroform, kuncibilika kancane emanzini

 

Sebenzisa:

- Ama-Chemical reagents: avame ukusetshenziswa njengama-sulfhydrylation reagents ku-organic synthesis for synthesis of sulfhydryl compounds.

- Ukusetshenziswa kwezentengiso: i-3-mercapto-2-butanone, njenge-reagent ye-sulfhydryl, ivame ukusetshenziswa ekulungiseni izithasiselo zenjoloba, ama-accelerator enjoloba, i-glyphosate (i-herbicide), ama-surfactants, njll.

 

Indlela:

Indlela evamile yokulungiswa kwe-3-mercapto-2-butanone ukusabela kwe-hexane eyodwa ne-hydrogen sulfide. Isinyathelo esiqondile ukusabela i-hexanone nge-hydrogen sulfide ngekholomu yejeli ye-silica ukuze uthole i-3-mercapto-2-butanone.

 

Ulwazi Lokuphepha:

- I-3-mercapto-2-butanone iwuketshezi oluvuthayo futhi kufanele igwenywe emalangabini avulekile noma amazinga okushisa aphezulu.

- Gqoka izinyathelo zokuzivikela ezifanele njengezingilazi zokuzivikela, amagilavu ​​nezingubo ezifanele ezingaqhumisi ngesikhathi sokusetshenziswa.

- Qonda futhi ulandele izinqubo zokusebenza ezifanele kanye neziqondiso zokusebenza zokuphepha ngaphambi kokusetshenziswa.

- Gwema ukuthintana nezinto ezifana nama-oxidants, ama-asidi aqinile, izisekelo eziqinile, nama-oxidants aqinile ukuze uvimbele ukusabela okuyingozi.

- Uma uthintana ngephutha, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha ngokushesha.

 

Kubalulekile ukusebenzisa nokuphatha lesi sakhi ngokuphepha nangokuhambisana nemithethonqubo kanye nemihlahlandlela.
