The Dipole Moment of Tri-isopropanolamine Borate in Benzene

Abstract

Solutions of the cyclic boric acid ester, tri-isopropanolamine borate, in benzene have been studied by dipole moment measurements at 25 and 50°C. The molecule has a dipole moment of 6.69 D, and the concentration dependence of the polarization indicates association of the solute, with end-to-end association predominating.
