摘要
Abstract
1,3-cyclohexanedione (CHD) has generally been industrially produced from the hydrogenation of resorcinol (RES). In this paper, the analysis and purification of the resorcinol hydrogenation products were studied by GC-MS. A gas chromatography method was established to quantitatively analyze the resorcinol and 1,3-cyclohexanedione. The stability of resorcinol and 1,3-cyclohexanedione in several organic solvents were studied by GC-MS, the results show that the acetonitrile is the most favorable solvent for the extraction and post processing. Then the acetonitrile was used as recrystalization solvent for 1,3-cyclohexanedione and a higher purity was obtained.关键词
