Gabatarwa

Salicylaldehyde wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shirye-shirye da bayanan aminci na salicylaldehyde:

 

inganci:

- Bayyanar: Salicylaldehyde ruwa ne mara launi zuwa rawaya tare da ƙamshin almond na musamman.

- Solubility: Salicylaldehyde yana da babban narkewa a cikin ruwa kuma yana narkewa cikin mafi yawan kaushi na kwayoyin halitta.

 

Amfani:

- dandano da dandano: Salicylaldehyde yana da ƙamshin almond na musamman kuma ana amfani da shi a cikin turare, sabulu da taba a matsayin ɗaya daga cikin abubuwan ƙamshi.

 

Hanya:

- Gaba ɗaya, ana iya samar da salicylaldehyde daga salicylic acid ta hanyar halayen redox. Mafi yawan amfani da oxidant shine acidic potassium permanganate bayani.

- Wata hanyar shiri ita ce samun salicylyl barasa ester ta chlorination ester na phenol da chloroform catalyzed ta hydrochloric acid, sa'an nan kuma samun salicylaldehyde ta hydrolysis dauki catalyzed ta acid.

 

Bayanin Tsaro:

- Salicylaldehyde sinadari ne mai tsauri kuma yakamata a nisanta shi daga haɗuwa da fata da idanu kai tsaye.

- Lokacin amfani ko sarrafa salicylaldehyde, kula da yanayin samun iska mai kyau kuma a guji shakar tururinsa.

- Lokacin adana salicylaldehyde, yakamata a adana shi a cikin akwati mai hana iska, nesa da ƙonewa da kuma abubuwan da ke haifar da iskar oxygen.

- Idan an sha salicylaldehyde ko an shaka ta bisa kuskure, nemi taimakon likita nan da nan.
