Is salicylic acid soluble in water?

Salicylic acid is not readily soluble in water at room temperature. It needs to be converted to salicylate if you want it to dissolve completely in water. Its solubility is also dependent on the pH of the solvent. It dissolves very well in water at a pH level of 3.

Is cinnamic acid saturated or unsaturated?

Cinnamic acid, an unsaturated carboxylic acid, is the chief constituent of the fragrant balsamic resin storax.

How cinnamic acid is formed?

Cinnamic acid is easily obtained by Perkin synthesis using benzaldehyde in ace- tic acid anhydride in the presence of weak bases such as acetate salts from alkali met- als [6-7]. Perkin reaction is the method most frequently used for the synthesis of cinnamic acid and its derivatives .

Is cinnamic acid ortho para directing?

Cinnamic acid is ortho/para directing only for nucleophiles. This can be explained as, C6H5-C=CH-COOH has a double bond connected to the phenyl ring and a carboxylic acid functional group to its double bond.

How is cinnamic acid synthesized?

Cinnamic acid was prepared by oxidation of benzalacetone which was synthesized by condensing benzaldehyde and acetone. For producing benzalacetone, benzaldehyde was reacted with acetone in 1% NaOH solution. … The benzalacetone was further oxidized with sodium hypochlorite to give 88.2% of cinnamic acid, m.p. 133°C.
