SYNTHESIS AND STUDY OF ETHYLENE GLYCOL BIS-Α-DINAPHTHYL DIACETATE AND ETHYLENE GLYCOL BIS-DIAMINODIBENZOATE ESTERS IN THE PRESENCE OF IONIC-LIQUID (N-METHYLPYRROLIDONE HYDROSULFATE) AND NANO-ZnO CATALYSTS

Abstract

In the presented article were synthesized in the presence of n-methylpyrralidonhydrosulfate catalyst based on α naphthylacetic acid and ethylene glycol (3% based on α-naphthylacetic acid) in a ratio of 2:1, at a temperature of 110°C, for 4-5 hours, with 80% yield of ethylene glycol bis-α-dinaphthyl diacetate ester; based on p-aminobenzoic acid and ethylene glycol in the presence of a nano-ZnO catalyst (7% by weight of the amino acid) in a ratio of 2:1, at a temperature of 80-90 °C, for 5-6 hours with a yield of 65% ethylene glycol-bis-diaminodibenzoate ester. The physicochemical parameters of the synthesized esters were determined by analytical and spectral methods. The synthesized esters can be used in industry as an antioxidant - additive of diesel fuel and in other areas.
