Process for the purification of p-dioxanone |
| abstract |
The present invention relates to a method for purifying para-dioxanone, comprising: (1) crystallizing para-dioxanone by cooling para-dioxanone; (2) crushing and filtering the crystallized para-dioxanone; (3) drying the filtered para-dioxanone particles at a temperature below the melting point of the para-dioxanone under high vacuum; And (4) heat-melting the dried para-dioxanone and distilling under reduced pressure. According to the method for purifying para-dioxanone of the present invention, a high yield of at least 99.9% of high purity para-dioxanone is obtained. It can be obtained simply. |
