Isingeniso
I-salicylaldehyde iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nemininingwane yokuphepha ye-salicylaldehyde:
Ikhwalithi:
- Ukubukeka: I-salicylaldehyde iwuketshezi olungenambala ukuya kokuphuzi olunephunga elikhethekile le-alimondi elibabayo.
- Ukunyibilika: I-salicylaldehyde inokunyibilika okuphezulu emanzini futhi iphinde incibilike kuzincibilikisi eziningi zemvelo.
Sebenzisa:
- Ama-flavour nama-flavour: I-salicylaldehyde inephunga elimnandi le-alimondi elibabayo elihlukile futhi ijwayele ukusetshenziswa kumakha, izinsipho nogwayi njengenye yezingxenye zephunga.
Indlela:
- Ngokuvamile, i-salicylaldehyde ingakhiqizwa ku-salicylic acid ngokusabela kwe-redox. I-oxidant esetshenziswa kakhulu yisisombululo esine-acidic potassium permanganate.
- Enye indlela yokulungiselela ukuthola i-salicylyl alcohol ester nge-chlorination ester ye-phenol ne-chloroform eyenziwe nge-hydrochloric acid, bese uthola i-salicylyldehyde nge-hydrolysis reaction catalyzed by acid.
Ulwazi Lokuphepha:
- I-salicylaldehyde iyikhemikhali enokhahlo futhi kufanele igwenywe ukuthintana ngqo nesikhumba namehlo.
- Uma usebenzisa noma uphethe i-salicylaldehyde, gcina izimo ezinhle zokungenisa umoya futhi ugweme ukuhogela umhwamuko wayo.
- Lapho ugcina i-salicylaldehyde, kufanele igcinwe esitsheni esingangeni moya, kude nokuvutha kanye nama-oxidants.
- Uma i-salicylaldehyde idliwe noma ihogelwe ngephutha, funa usizo lwezokwelapha ngokushesha.
