2-Carboxybenzaldehyde

Carboxybenzaldehyde waxay leedahay sifooyinka aldehyde iyo acid. Waxa loo samayn karaa ester leh aalkolo, lagana dhigo Ag(NH3)2NO3, oo loo sameeyo oxime leh H2NOH. Kuleylka ilaa barta dhalaalka, waxaa loo samayn karaa anhydride (diphenylphthalide ether).

Waa dhexdhexaad muhiim ah oo ka mid ah isku dhafka daawooyinka antipyretic iyo xanuunka. Waa budo crystalline caddaan ama caddaan ah oo leh barta dhalaalaysa 96 ~ 100â.

Carboxyl benzaldehyde waxaa badanaa laga helaa bromination iyo hydrolysis of phenol. Heat phenol, dhex mara falcelinta bromine, xakamaynta xawaaraha ku gudubta, samee gaaska dabada falcelinta asal ahaan ma jiro dheecaan bromine ah, dhex mara bromine, reactant ku dar biyo, hydrolysis. O-carboxyl benzaldehyde ayaa soo degtay kadib qaboojinta.

Waxaa lagu helay bromination iyo hydrolysis of phenol. Kuleyli phthalein ilaa 140-145â, falcelinta bromine, xakamee xawaaraha soo galitaanka, si gaaska dabada falcelintu uusan asal ahaan ka soo bixin uumiga bromine. Ka dib ka saarista bromiinka, hadhaaga hydrogen bromide waxaa laga saaray kaarboon laba ogsaydh iyo depression at 120â buug kiimikaad. Dareen-celinta waxa lagu shubay biyo 0.5h oo biyo karkaraya lagu maydho. O-carboxyl benzaldehyde ayaa soo degtay kadib qaboojinta. Wax-soo-saarka 60%.
