How to prepare 3 phenylpropanoic acid?

A low boiling point fraction passes over first, followed by diethyl benzylmalonate. Hydrolyse the latter with a solution of 75 g of potassium hydroxide in 75 ml of water and isolate the resulting crude 3-phenylpropanoic acid as described previously, using 180 ml of 5 M sulphuric acid in the acidification stage.

What is valeric acid made of?

Valeric acid or pentanoic acid is a straight-chain alkyl carboxylic acid with the chemical formula CH 3(CH 2) 3COOH. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. It is found in the perennial flowering plant Valeriana officinalis, from which it gets its name.

Is phenyl propanoic acid?

3-phenylpropionic acid is a monocarboxylic acid that is propionic acid substituted at position 3 by a phenyl group. It is a monocarboxylic acid and a member of benzenes. It derives from a propionic acid.

How do you make 3-phenyl propionic acid from diethylmalonate?

Synthesis of 3-phenyl propionic acid (hydrocinnamic acid) from diethylmalonate. Principle: Here 3-phenylpropionic acid is produced finally from benzylated malonic acid due to decarboxylation on heating.

How do you prepare benzylated malonic acid from diethyl malonate?

First freshly prepared sodium ethoxide reacts with diethyl malonate giving enolate ion which alkylate with benzyl chloride to produce benzylated malonic ester. Then hydrolysis occurs with the benzylated malonic ester to give benzylated malonic acid in presence of a base like NaOH.1

What is malonic ester synthesis?

Malonic Ester Synthesis Reaction type :Nucleophilic substitution, then ester hydrolysis and finally decarboxylation (!) Summary Malonic esters are the esters of malonic acid (systematic name : propanedioic acid) The most common example of a malonic ester is diethyl malonate Diethyl malonate is:
