3-(1-Cyanoethyl)benzoic Acid CAS 5537-71-3 - Quality Product from China Suppliers and Factory
3-(1-cyanoethyl)benzoic acid is prepared from methyl 3-cyanomethylbenzoate, which is first reacted with dimethyl carbonate in the presence of potassium carbonate to obtain methyl 3-(1-cyanoethyl)benzoate, which is then hydrolyzed, acidified, crystallized, and purified to obtain 3-(1-cyanoethyl)benzoic acid.
Methyl 3-cyanomethylbenzoate reacts with dimethyl carbonate using potassium carbonate.
Formation of methyl 3-(1-cyanoethyl)benzoate as the key intermediate product.
Hydrolysis, acidification, crystallization, and final purification to obtain the pure acid.
The primary starting material is methyl 3-cyanomethylbenzoate.
Dimethyl carbonate is used as the reactant in the presence of potassium carbonate as a catalyst or base.
The process forms methyl 3-(1-cyanoethyl)benzoate before it is converted into the final acid form.
Purification is achieved through a sequence of hydrolysis, acidification, and crystallization.
After the reaction, the mixture undergoes hydrolysis and acidification to yield the final carboxylic acid structure.
