【発明の名称】アジピン酸の製造においてシクロヘキサンから酢酸を除去するための方法および装置
Document Type and Number:
Japanese Patent JP2001517647
Kind Code:
A
Abstract:
This invention relates to methods and devices for removing acetic acid from cyclohexane in the direct oxidation of cyclohexane to adipic acid, especially after recycling catalyst which is precipitated by introduction of additional cyclohexane. The removal of acetic acid is preferably conducted by use of rather small amounts of wash-water in one to three stage extractors. A two stage reactor is preferable as being more efficient.
