抄録
The following kinetic equation is obtained for the polyesterification of 2, 2-dimethyl-1, 3-propanediol with various dibasic acids at different temperatures in the absence of a foreign acid and solvent.<BR>These reactions were found to be subject to general acid catalysis in the absence of a foreign acid and solvent, where a catalyst is the dibasic acid itself.<BR>All of data obtained in this paper support the setting of the above equation over the range of 0 to 95% polyesterification for the case of [OH] 0/[COOH] 0=1.05, where [OH] 0 is the initial concentration of the hydroxyl group, [COOH] 0 is the initial concentration of the carboxyl group, and k′=4.8×10-2.<BR>The order of reactivities of dibasic acids with 2, 2-dimethyl-1, 3-propanediol are as follows.<BR>Maleic anhydride>succinic acid>adipic acid=sebacic acid>o-phthalic acid.<BR>The activation energies are all found to be 15±0.5kcal/mol, therefore the polyesterification reactions between 2, 2-dimethyl-1, 3-propanediol and various dibasic acids are same reaction mechanism.
