【Abstract】 The esterification reaction constants-values determimed for the catalysis on hydrates of Sulfates in this paper.It is discovered that the value of the +I type Carboxylic acid is different from that of the -I type carboxylic acid and therelationship between them is as follows. ∠α=8.32(X_i/r)-129.0 Where ∠αis the included angle between the reaction constant of the +I type carboxylic acid and that of the -I type acid, r is the orbital radius of the Matal atom in catalyzer, X_i is the electronegativity of the metal atom.更多还原
