Abstract: The invention provides a process for the production of a polyester which comprises initiating a reaction between a poly-terminal epoxide, a mono-terminal epoxide and a cyclic diacid anhydride in the presence of a catalytically effective quaternary salt heating to a point at which the reaction becomes a self-sustaining exothermic reaction and controlling the reaction such that the temperature of the mixture is not reduced until after the exothermic reaction has begun to subside.

Abstract: The process for the conversion of saturated hydrocarbons having from 4 to 10 carbon atoms to maleic anhydride is enhanced when a mixture of oxygen and saturated hydrocarbon is contacted with catalysts comprising phosphorus, vanadium, oxygen and an element selected from the group consisting of titanium, silicon, or mixtures of these elements.
