Okwu mmalite

Salicylaldehyde bụ ihe mejupụtara ya. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke salicylaldehyde:

 

Ogo:

- Ọdịdị: Salicylaldehyde bụ mmiri mmiri na-acha odo odo na-esi ísì ụtọ pụrụ iche.

- Solubility: Salicylaldehyde nwere nnukwu solubility na mmiri yana solubility na ọtụtụ ihe mgbaze organic.

 

Jiri:

- Atọ ụtọ na ụtọ: Salicylaldehyde nwere ísì ụtọ almond pụrụ iche ma na-ejikarị eme ihe na-esi ísì ụtọ, ncha na ụtaba dịka otu n'ime ihe na-esi ísì ụtọ.

 

Usoro:

- N'ozuzu, salicylaldehyde nwere ike ịmepụta site na salicylic acid site na mmeghachi omume redox. Ihe oxidant a na-ejikarị bụ potassium permanganate acid acid.

Usoro nkwadebe ọzọ bụ ịnweta salicylyl alcohol ester site na chlorination ester nke phenol na chloroform catalyzed site hydrochloric acid, wee nweta salicylaldehyde site hydrolysis mmeghachi omume catalyzed site acid.

 

Ozi nchekwa:

- Salicylaldehyde bụ kemịkalụ siri ike ma ekwesịrị ịzere ya site na kọntaktị akpụkpọ na anya.

- Mgbe ị na-eji ma ọ bụ na-ejikwa salicylaldehyde, nọgide na-enwe ọnọdụ ikuku dị mma ma zere ikuku ume nke vapors ya.

- Mgbe ị na-echekwa salicylaldehyde, a ga-edobe ya n'ime akpa ikuku, na-adịghị na mgbanye ọkụ na oxidants.

- Ọ bụrụ na etinyere salicylaldehyde ma ọ bụ kuru ya n'amaghị ama, chọọ enyemaka ahụike ozugbo.
