Abstract: The process of the present invention provides a method of obtaining a high yield of water or acid soluble nitrate esters without the use of organic solvents in the nitration reaction or the production of unstable products or by-products. The process involves the nitration of an organic hydroxy-containing compound with a suitable nitrating agent such as nitric acid in the absence of organic solvents in the nitration reaction. The reaction mixture is neutralized, causing the nitrate esters to precipitate or separate from the neutralized nitrate solution. The nitrate ester is then recovered, and any dissolved nitrate salts can be removed therefrom by gentle washing with water or a dilute halide solution. As provided by the process of the present invention, no organic solvents are used in the nitration reaction and average yields range from about 80 % to about 95 %.
