Acidity Study of Donor-Acceptor Complexes of Boric Acid with Polyols for Oil Displacing Compositions
The results of theoretical and experimental studies of the acidity of donor-acceptor complexes of boric acid with polyols – glycerol and sorbitol, which were used in the development of oil-displacing compositions, are presented. A model of donor-acceptor acid-base equilibria in coordinating polyol solvents has been created, due to which the constants of polyolboric acids formation and ionization were determined by pH-meter and electrical conductivity methods. The obtained constant values were used to calculate the compositions buffer capacity. Due to the using a mixture of polyolboric acids in the compositions at various ratios it was possible to regulate the range of the buffer action
