  • PROCESS FOR PREPARING EPSILON-CAPROLACTONE
    Publication number: 20100168445
    Abstract: The present invention provides a process for preparing ?-caprolactone in a purity above 99%, in which 6-hydroxycaproic ester comprising from 0.5 to 40% by weight of adipic diester is cyclized in the gas phase at from 150 to 450° C. in the presence of oxidic catalysts and ?-caprolactone is obtained from the cyclization product by distillation.
