The Effect of Solvent Origin on the Spectrophotometric Determination of m-Phenylen-Bis-Maleinimide (Phbmi)

摘要

The absorption spectra of PhBMI are studied in 9 organic solvents of different polarity. A hypsochromic shift of the absorption maxima attributed to an increase in the solvent polarity is found. The linear correlations between #lambda#_(max), #epsilon#_(max) and parameters, characterizing the solvent polarity are obtained. The methods of Spectrophotometric determination of PhBMI in different solvents are developed. The threshold of determination is 0.5-6.0 #mu#g/ml.
