Isingeniso

I-Dipropyl sulfide. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dipropyl sulfide:

 

Ikhwalithi:

Ukubukeka: I-Dipropyl sulfide iwuketshezi olungenambala.

Ukunyibilika: Iyancibilika kuma-organic solvents futhi incibilika kancane emanzini.

Ukuminyana: Ukuminyana ekamelweni lokushisa cishe ku-0.85 g/ml.

Ukuvutha: I-Dipropyl sulfide iwuketshezi oluvuthayo. Umhwamuko wawo ungakha izingxube eziqhumayo.

 

Sebenzisa:

Njenge-organic synthesis reagent: i-dipropyl sulfide ivame ukusetshenziswa njenge-ejenti eqeda amanzi emzimbeni, i-solvent kanye ne-ejenti yokunciphisa ekuphenduleni kwe-organic synthesis.

Njenge-lubricant: ngenxa yezakhiwo zayo ezinhle zokugcoba, ivame ukusetshenziswa njengengxenye kumafutha kanye nama-preservatives.

 

Indlela:

Ngokuvamile, i-dipropyl sulfide ingatholwa ngokusabela kwe-mercaptoethanol ne-isopropylammonium bromide. Izimo zokusabela ngokuvamile zidinga ukwenziwa ngaphansi kokuvikelwa kwamagesi angenayo.

 

Ulwazi Lokuphepha:

I-Dipropyl sulfide iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye nemithombo yokushisa ephezulu.

Ukuchayeka ku-dipropyl sulfide kungase kubangele ukucasuka kwesikhumba nokucasuka kwamehlo, futhi amagilavu ​​okuvikela kanye nezibuko kufanele kugqokwe ngesikhathi sokusetshenziswa.

Uma i-dipropyl sulfide idliwe kakhulu noma ihogelwe, funa usizo lwezokwelapha ngokushesha.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
