Prediction of liquid viscosities of phosphorus-containing compounds by Souders' method

Abstract

Souders' method of predicting the viscosities of liquid compounds from structural information has been extended to include the contribution from the phosphorus atom. The phosphorus contribution has been predicted from the critical pressure to be 67.1. The prediction method has been tested using data available on 15 phosphorus-containing compounds. The results are comparable with those reported in the literature for group contribution methods in general.
