Study on the synthesis of Olaxitam using NaA molecular sieve membrane reactor
In order to solve the technical difficulties of complex synthesis process and low product yield of Olaxitam,this paper uses NaA type molecular sieve membrane reactor to prepare Olaxitam through coupling steam permeation technology and cyclization reaction,and investigates the influence of process conditions on treatment efficiency.The results showed that under the conditions of vacuum degree of 0.02~0.05MPa on the permeation side of NaA molecular sieve membrane,reaction temperature of 85℃and reaction time of 24 hours,the product yield of Olaxitam was 80.5%.After NaA molecular sieve membrane fouling and regeneration,the recovery rate of permeate flux reached 99.1%.
