Direct Determining Stability Constants and Absorption Coefficients of Coordination Compound By Iterative Graphic Method
LI Ke-qun(Department of Chemistry,Tongji University,Shanghai 200092,China)An iterative graphic method for direct determining stability constants and absorption coefficients of coordination compound whose maximum coordination is 3 was presented in this paper.This method used the properties of limiting values and first-order differential graph of average absorption coefficients.The imaginary data of two coordination compounds were used for calculation,and their results agreed with practical values.
Applications of Clean Chemistry
ZHOU Qin-tao CHEN Shi-yuan(School of Chemitsry & Materials Science, Hubei University,Wuhan 430062,China )Clean chemistry is a kind of chemistry to prevent pollution in beginning. There centresearch and development in the field are mainly including the greening of chemical reaction, feed stocks and starting materi- als, catalyst, solvents and products. Based on above-mentioned mainline, there new examples of clean chemis- try are reviewed.
