A process for removal of aromatics from recycling paraffins in alkylbenzene production was developed, in which a fixed bed was adopted to selectively adsorb aromatics.

Asymmetric Regio- and Stereo-selective Alternating Copolymerization of CO_2 and Epoxides;

Recent research works on one-pot synthesis of dimethyl carbonate from epoxides,carbon dioxide and methanol were reviewed.

Dimethyl carbonate can be directly synthesized from CO 2,methanol and epoxide by using a two component catalyst.

Study on Structure-Refractive Index Relationship of Cycloalkanes and Alkanes;

Predicting the Refractive Index of Cycloalkane Using Structure Information Autocorrelation Topological Index;

Relativity between Randic’ branch degree index and boiling points of cycloalkanes;

Studies on QSPR Between GC Retention Indices And Topological Indices of Cycloalkanes by Using Projection Pursuit Method;

Based on the characteristics of molecular structure, the adjacent matrix and dyeing matrix were used to characterize the molecular structure of alkane and cycloalkane, a new method——the group contribu-tion method, was developed to calculate the boiling points of alkane and cycloalkanes from molecular struc-ture.
