Abstract
Processes for the production of ethylene glycol phosphate esters using ethylene glycol and phosphoric acid. These reactants mixed and heated with an esterification promoter which can be an oxide or hydroxide, such as an alkali, alkaline earth or other metal oxide or hydroxide. The mixture can be reacted at atmospheric pressures and temperatures in excess of 150.degree. C., thus speeding the esterification. Boiling is preferred during the reaction to improve water removal. Excess ethylene glycol can advantageously be used to aid in efficient conversion. Excess unreacted ethylene glycol is also significant when the reaction products are used as foliar fertilizers. The cations of some promoters substitute into the esters and can be used to provide secondary or trace elements of nutritional value when the reaction products are used as foliar fertilizers.
