It has been discovered that when co-nitrating a mixture of trimethylolethane and diethylene glycol, a storage stable spent acid can be obtained if during the co-nitration an excess of from about 60 to about 100% by weight of nitric acid over that stoichiometrically required is employed.
In a process of co-nitrating a mixture of trimethylolethane and diethylene glycol with a mixture of sulfuric and nitric acids, the improvement of using an excess of between about 65 to about 100% by weight of nitric acid above the stoichiometric requirement for the co-nitration.
