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 formulaR=CH, CH, n-CH, n-CH, n-CHinvolves reaction of benzene with CCland alcohol (methanol, ethanol, n-propanol, n-butanol, n-pentanol) in the presence of iron metal and acetyl acetone in molar ratio [Fe(met)]:[acetyl acetone]:[benzene]:[CCl]:[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.1 tbl, 26 ex |
