Intshayelelo
I-Tosylisocyanate, ekwabizwa ngokuba yiTosylisocyanate. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-p-toluenesulfonylisocyanate:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala okanye olumthubi olukhanyayo.
-I-Solubility: Inyibilika kwizinyibilikisi eziqhelekileyo ze-organic, njenge-ethanol, i-dimethylformamide, njl.
- Ukuzinza: Ukuzinza, kodwa ukudibanisa namanzi kunye ne-alkalis eqinile kufuneka kugwenywe.
Sebenzisa:
I-Tosyl isocyanate isetyenziswa ikakhulu njengesixhobo sokusebenza okanye ukuqalisa kwi-organic synthesis reactions. I-Tosyl isocyanate ingasetyenziselwa njenge-catalyst kunye neqela elikhuselayo kwi-synthetic chemistry.
Indlela:
Indlela yokulungiselela i-toluenesulfonyl isocyanate idla ngokufunyanwa ngokuphendula i-benzoate sulfonyl chloride kunye ne-isocyanate. Amanyathelo athile abandakanya ukuphendula kwe-sulfonyl chloride benzoate kunye ne-isocyanate phambi kwesiseko, kwigumbi okanye kwiqondo lokushisa eliphantsi. Iimveliso zokusabela zivame ukutsalwa kwaye zihlanjululwe ngeendlela ezifana ne-solvent extraction kunye necrystallization.
Ulwazi ngoKhuseleko:
- Ukuqhagamshelana nolusu kunye namehlo kufuneka kugwenywe ngexesha lokusebenza ukuphepha ukucaphuka okanye ukulimala.
- Indawo yokusebenza kufuneka ingene umoya kwaye uphephe ukuphefumla umphunga wayo.
- Ngexesha lokugcinwa kunye nokuthwala, ukudibanisa nomswakama kunye ne-alkali enamandla kufuneka kugwenywe ukukhusela ukuphendula okungakhuselekanga.
- Landela iinkqubo ezifanelekileyo zokhuseleko kunye nemilinganiselo kwaye unxibe izixhobo ezifanelekileyo zokuzikhusela xa usebenzisa kunye nokuphatha i-tosyl isocyanate.
