    Abstract: 1,138,360. Nitric esters of polyalkanols. STAMICARBON N.V. 26 Sept., 1966 [1 Oct., 1965], No. 42957/66. Heading C2C. Polyhydric alkanols are esterified with nitric acid by reacting with a nitrating acid in a liquid sulphur dioxide medium. Glycerol di- and trinitrates, ethylene glycol dinitrate and diethylene glycol dinitrate are specified and the nitrating acid is a mixture of nitric and sulphuric acid or anhydride with a preferred nitric acid content of 38-43 mol. per cent. The autogenous oxidation of liquid sulphur dioxide removes the heat generated during esterification.
