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.
