| Abstract: | In this paper,the new approach is introduced that the ethyl pyruvate was synthesized via catalytic oxdation of ethyl lactate by NO_2 with acceptable yield(>75%).The purity of the product was upto 98%.The reaction conditions were optimized in terms of oxidant dosage,reaction time,reaction temperature,catalyzer dosage,etc.The greatest advantage of the process was that it provided a pollution-free method for treatment and recovery of the waste gas NO_2. |
