| Abstract: | The values of reaction enthalpy of B(OH) with polyhydroxy comPounds were deterthened by using calorimeter at 298.2K. The coordination enthalpy of boric acid with polydydroxy compounds and the standard enthalpy of formation of the coordination ions were calculated. The coordination numbers of the coordination reactions of B(OH)' with mannitol, d-sorbitol, glycerol and a-dglucose were determined by the values of coordination enthalpy. For maunitol and d-sorbitol, the number of coordination with B(OH) is 2; for the glycerol and a-d-glucose, it is 1. |
