METHOD OF PRODUCING ALKYL BENZOATES Russian patent published in 2013 - IPC C07C69/78 C07C67/00 C07C67/39 C07C67/44 

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry, particularly a method of producing alkyl benzoates, which are used as an aroma additive in the fragrance industry. The method of producing alkyl benzoates of formula R=CH₃, C₂H₅, n-C₃H₇, n-C₄H₉, n-C₅H₁₁ involves reaction of benzene with CCl₄ and alcohol (methanol, ethanol, n-propanol, n-butanol, n-pentanol) in the presence of iron metal and acetyl acetone in molar ratio [Fe⁰(met)]:[acetyl acetone]:[benzene]:[CCl₄]:[alcohol]=10-20:1-10:20:20-400:20-400, at temperature of 130-150°C for 4-8 hours in an argon atmosphere. Output of ethyl benzoate was 42%, output of n-propyl, n-butyl and n-pentyl was 50%, 32% and 30%, respectively.

EFFECT: high efficiency of the method.
