| Abstract: | The direct hvdroxvlation of phenoI to catechol(CAT )and hvdro-quinone(HQ) by hydrogen peroxide in the presence of titanium silicalite-2 (TS-2)with MEL topology has been investigated. Good yields of products and high selectivity of hydrogen peroxide were obtained under mild reaction condition. A gas chromatographic method for the quantitative determination of products in the mixture was developed with diphenyl as internal standard.The OV-25 is a good stationary phase for the quantitative analysis with satisfac-tory resolution. |
