Abstract: 538,446. Ethereal nitrates. STANDARD OIL DEVELOPMENT CO. Feb. 8, 1940, No. 2476. Convention date, March 30, 1939. [Class 2 (iii)] Secondary aliphatic nitrates are produced by nitrating compounds containing a secondary alcohol group at a temperature not above -10‹C. using a nitration mixture containing at least 50 per cent. excess of nitric acid and also sulphuric acid and water, the molecular ratio of water to sulphuric acid being not greater than 1.6 + .004 (E-50) where E is the percentage excess of nitric acid. A part of the sulphuric acid may be replaced by an acid of phosphorus or a water-soluble fatty acid, such as phosphoric or acteic acid, in which case the lower limit of nitric acid may be used ; otherwise the excess of nitric acid should be at least 100 per cent. Examples describe the production of the nitrate of secondary amyl alcohol, and it is stated that other alcohols that may be used are substituted and unsubstituted mono- and polyhydric alcohols such as isopropyl alcohol, 2 hydroxyhexane, 2-3 dihydroxybutane, 2-3 dihydroxypentane, 2-methyl-2-nitro-1:3-dihydroxybutane, 3-chloro-2-hydroxybutane, the secondary alcohols prepared by hydration of olefines containing up to 12 or 14 carbon atoms (from the cracking of paraffin wax) and 1-12-dihydroxyoctadecane.
