Preparation of plasticizer or polyol esters by the staged addition of the lower boiling point reactant |
摘要 |
A process for the esterification of acids or anhydrides with alcohols or a polyhydroxy compound wherein the lower boiling point reactant is added to the reaction vessel in stages such that it is present in an amount of at least about 5% of the stoichiometric requirements of the total lower boiling point reactant required to react with the limiting reagent, and wherein the concentration of the lower boiling point reactant is monitored so that additional reactant having the lower boiling point can be subsequently added in stages to the reaction mixture in order to maintain a certain predetermined concentration of the lower boiling point reactant.
