Thermo Fisher Scientific Develops an Effective Method for the Determination of Dibasic Acids Generated During Cyclohexane Oxidation
Thermo Fisher Scientific is pleased to proclaim an efficient method to determine succinic, glutaric, and adipic acids in solutions of mixed dibasic acids produced during cyclohexane oxidation.
- San Jose, CA (1888PressRelease) July 20, 2012 - Thermo Fisher Scientific is proud to announce an effective new method for the determination of succinic, glutaric, and adipic acids in solutions of mixed dibasic acids generated during cyclohexane oxidation. Application Note 285: Determination of Succinic, Glutaric, and Adipic Acids as Quality Control of Cyclohexone Production demonstrates use of the Thermo Scientific Dionex UltiMate™ 3000 RSLC system with the Thermo Scientific Acclaim™ OA column and mass spectrometry (MS) detection to achieve a fast baseline separation of these three dibasic acids with good resolution values (Rs ≥ 2.6), good method reproducibility, excellent linearity within 0.1 to 5 mg/L, and accurate results for industrial samples.
Cyclohexone is the key intermediate for the production of adipic acid, an important compound for the synthesis of nylon 66. Cyclohexane oxidation is the normal method for the production of cyclohexone; and succinic, glutaric, and adipic acids, as well as their dehydration products, are the main by-products. The three aliphatic dicarboxylic acids are also important chemical raw materials, and their determination is important for the quality control of cyclohexone production and recycling of the by-products.
