Method for obtaining 1,2-epoxy-5.9-cyclododecadiene

摘要

the object of the application is the way of 1,2 - epoxy - 5.9 - cyklododekadienu. during epoksydacji 1,5,9 - cyklododekatrienu using hydrogen peroxide, in the presence of organic solvent.this method is characterized by that,that process epoksydacji leads in the presence of phosphoric acid and sodium wolframianu - as a catalyst and hydrogen sulfate as catalyst epoksydacji metylotrioktyloamoniowego transfer (man 1t talk aboutlocal. the process is maintaining the reaction mixture at 30 - 70u00b0c during intense mixing during 1 to 2 hours.molar ratio of acid to sodium wolframianu - phosphoric acid is 0.5 - 4.0: 1. molar ratio of hydrogen peroxide to wolframianu sodium is 37 - 300: 1.molar ratio of hydrogen peroxide to 1,5,9 - cyklododekatrienu is 0,75 - 1.5: 1. as organic solvent is used, m -, o -, p - xylene or their mixture.molar ratio metylotrioktyloamoniowego to wolframianu sodium hydrogen sulphate is 0.3 - 0.5: 1.
