A New Mixture Topological Index A in the Related Research of Biomass Blended Fuels

摘要

In the present work, we synthesis glycerol ether by the biomass glycerol. Then the blended fuel was prepared with ethanol, gasolines and glycerol ether. In addition, for the oxygen-containing materials, the distance matrix D based on molecular was modified by the sum of the molecular relative bond intensity matrix R-i and the branching parameter g(i). Then the single topological index X and the mixed topological index A were established. The quantitative structure-property relationship (QSPR) of the mixture topological index A and the physicochemical properties of the glycerol ether blended fuels such as density, kinematic viscosity, calorific value and cetane number was studied by linear regression method. The mixed topological index A can be fitted well with the physicochemical properties of biomass blended fuels, and the changes of the physical and chemical properties of the blended fuels can be well reflected by the four QSPR models.
