Abstract: Glycol monoborate esters of the formula:  <FORM:0935416/IV(a)/1> (where R represents a hydrocarbon radical containing 2 to 20 carbon atoms, 2 to 4 carbon atoms of which form an alkylene chain linking the oxygen atoms, and R1 represents an unsubstituted alkyl radical containing 3 to 20 carbon atoms, a cycloalkyl radical, or an aryl substituted alkyl radical the alkyl moiety of which contains at most 6 carbon atoms) are made by reacting together in substantially equimolar proportions an alcohol of the formula R1OH, a glycol of the formula HO-R-OH and boric acid (the symbols R and R1 being as hereinbefore defined) in the presence of a hydrocarbon solvent, removing the water so produced as an azeotrope with the hydrocarbon solvent by distillation and recovering the glycol monoborate ester from the residual reaction mass.  It is preferred to use equimolar amounts of the reactants.  In a modification of the above method, the alcohol, the glycol and boric acid are heated together in the absence of a hydrocarbon solvent until all of the boric acid is in solution, a hydrocarbon solvent is then added to the hot reaction mass, the water which separates is removed, e.g. by draining or decanting off the upper hydrocarbon layer, and the hydrocarbon solution heated to remove the remainder of the water as an azeotrope with the solvent by distillation.  Suitable hydrocarbons are benzene, xylene, n-heptane or toluene.  Examples of starting materials and worked examples are given.
