Isingeniso
I-Tosylisocyanate, eyaziwa nangokuthi i-Tosylisocyanate. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-p-toluenesulfonylisocyanate:
Ikhwalithi:
- Ukubukeka: Uketshezi oluphuzi olungenambala noma olukhanyayo.
- I-Solubility: Incibilika kuzincibilikisi ezivamile ze-organic, njenge-ethanol, i-dimethylformamide, njll.
- Ukuzinza: Ukuzinza, kodwa ukuthintana namanzi nama-alkali aqinile kufanele kugwenywe.
Sebenzisa:
I-Tosyl isocyanate isetshenziswa kakhulu njenge-reagent noma into yokuqala ekuphenduleni kwe-organic synthesis. I-Tosyl isocyanate ingasetshenziswa njenge-catalyst neqembu elivikelayo kumakhemikhali okwenziwa.
Indlela:
Indlela yokulungiselela i-toluenesulfonyl isocyanate ivamise ukutholakala ngokuphendula i-benzoate sulfonyl chloride ne-isocyanate. Izinyathelo ezithile zihlanganisa ukusabela kwe-sulfonyl chloride benzoate ene-isocyanate phambi kwesisekelo, ekamelweni noma izinga lokushisa eliphansi. Imikhiqizo yokusabela ivame ukukhishwa futhi ihlanzwe ngezindlela ezifana nokukhipha i-solvent kanye ne-crystallization.
Ulwazi Lokuphepha:
- Ukuthintana nesikhumba namehlo kufanele kugwenywe ngesikhathi sokuhlinzwa ukugwema ukucasuka noma ukulimala.
- Indawo yokusebenza kufanele ingene kahle futhi igweme ukuhogela umhwamuko wayo.
- Ngesikhathi sokugcina nokuthwala, ukuthintana nomswakama kanye nama-alkali aqinile kufanele kugwenywe ukuvimbela ukusabela okungaphephile.
- Landela izinqubo zokuphepha ezifanele kanye nezinyathelo futhi ugqoke izinto zokuzivikela ezifanele uma usebenzisa futhi uphatha i-tosyl isocyanate.
