PROCESS FOR PREPARING CYCLODODECANONE
20190345101 · 2019-11-14 ·

The invention relates to a method for producing cyclododecanone (CDON). During the production, contaminated cyclododecane (CDAN) is produced. This can be separated from CDON by distillation (CDAN-containing fraction). The separation of CDAN and impurities such as 13-oxabicyclo [7.3.1]tridacane occurs by crystallizing out CDAN from the CDAN-containing fraction.
