Processing method of microparticle raw polyoxymethylene |
| abstract |
The present invention provides a post-treatment method of particulate microcrystalline polyoxymethylene comprising the following steps: (a) introducing particulate crude polyoxymethylene into extraction column 13 operated at a pressure in the range of 1 to 6 bar, (b) introducing the polar extractant into the extraction column 13 having a temperature in the range of 95 to 140 ° C. and a pressure in the range of 1 to 6 bar, The buffering material here buffered in the pH range of 7.5 to 11.5 is achieved by the process introduced into the extraction column 13 at 10 to 1000 ppm relative to the amount of polar extractant introduced. |
