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]tridecane occurs by crystallizing out CDAN from the CDAN-containing fraction.
本发明涉及一种生产
环十二酮(CDON)的方法。在生产过程中,会产生被污染的
环十二烷(
CDAN)。可通过蒸馏将其从 CDON 中分离出来(含
CDAN 的馏分)。
CDAN 和杂质(如 13-oxabicyclo [7.3.1]tridecane)的分离是通过从含
CDAN 的馏分中结晶出
CDAN 来实现的。
