Nhanganyaya
Salicylaldehyde ndeye organic compound. Iyi inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza salicylaldehyde:
Hunhu:
- Chitarisiko: Salicylaldehyde imvura isina ruvara kune yero ine yakakosha inonhuhwirira yemuarumondi.
- Solubility: Salicylaldehyde ine yakakwira solubility mumvura uye zvakare inonyungudika mune yakawanda organic solvents.
Shandisa:
- Kunhuhwirira uye zvinonhuwirira: Salicylaldehyde ine yakasarudzika inonhuwira yearumondi uye inowanzoshandiswa muzvinonhuwira, sipo uye fodya sechimwe chezvikamu zvekunhuhwirira.
Nzira:
- Kazhinji, salicylaldehyde inogona kugadzirwa kubva salicylic acid kuburikidza nekuita redox. Iyo inonyanya kushandiswa oxidant ndeye acidic potassium permanganate solution.
- Imwe nzira yekugadzirira ndeyekuwana salicylyl alcohol ester ne chlorination ester ye phenol uye chloroform catalyzed ne hydrochloric acid, uyezve kuwana salicylyldehyde ne hydrolysis reaction catalyzed by acid.
Zvekuchengetedza
- Salicylaldehyde ikemikari ine hutsinye uye inofanira kudzivirirwa kubva pakubata zvakananga neganda nemeso.
- Paunenge uchishandisa kana kubata salicylaldehyde, chengetedza mamiriro ekufema zvakanaka uye udzivise kufema kwemhute yayo.
- Paunenge uchichengeta salicylaldehyde, inofanirwa kuchengetwa mumudziyo usina mhepo, kure nekupisa uye oxidants.
- Kana salicylaldehyde ikamwiwa kana kufemerwa nekukanganisa, tsvaga rubatsiro rwekurapa nekukurumidza.
