dipolar aprotic solvent

[dī‚pō·lər ā‚präd·ik ′säl·vənt]
(organic chemistry)
A solvent with characteristically high polarity and low reactivity, that is, a solvent having a sizable permanent dipole moment that cannot donate labile hydrogen atoms to form strong hydrogen bonds; examples include acetonitrile, dimethyl sulfoxides, and hexamethylphosphoramide.

The present study is a part of our systematic investigation [4, 5] of thermodynamic properties of synthesized biologically active dihydro pyrimidines in dipolar aprotic solvents. In this paper, the concentration dependence of sound velocity and adiabatic compressibility coefficients for solutions of various substituted dihydro pyrimidines in N, N-dimethylformamide (DMF) and dimethylsulfoxide (DMSO) at 298.15 K are studied.
