| PURPOSE:To produce a nitric acid ester, in high yield and purity, economically in an industrial scale, easily under mild condition, using a regenerable reagent, by reacting a sulfonic acid ester with an organic quaternary ammonium nitrate. CONSTITUTION:The objective compound of formula III can be produced by reacting (A) the sulfonic acid ester of formula II (R'SO2 is sulfonic acid residue) obtained by the conventional sulfonation process of an alcohol of formula I (R is organic residue) with (B) the organic quaternary ammonium nitrate of formula IV(Q<+> is organic quaternary ammonium residue), e.g. a quaternary alkyl (or substituted alkyl) ammonium nitrate or a nitrate of a strongly basic anion exchange resin having quaternary ammonium as an exchangeable group. The process can be applied to a compound which is difficult to be nitrated by conventional methods. When the process is applied to an optically active compound, a nitrate having inverted absolute configuration is prepared without causing racemization. | ||||||

| PURPOSE: To obtain the titled compound in high yield economically and advantageously without troublesome operation, by reacting a tertiary alcohol with an amine adduct with sulfur trioxide as a sulfating agent under heating, cooling the reaction mixture, and adding a slightly soluble solvent to isolate the titled compound. CONSTITUTION: All the tertiary alcohols not only tertiary butanol are heated with an adduct of an amine, e.g. methylamine, cyclopropylamine, aniline or pyridine, of the formula R1R2R3N(R1, R2R3 are H, 1W10C alkyl or cycloalkyl; however, except when any one of R1, R2 and R3 is H) with sulfur trioxide, in an amount of equimolar with the tertiary alcohols at 0W120°C, and cooled to 0°C or below, and then a slightly soluble solvent, e.g. methanol or petroleum ether is added to deposit and isolate the aimed substance. The tertiary alcohols may be used in a large excess. COPYRIGHT: (C)1982,JPO&Japio | ||||||

| PURPOSE: To obtain the titled compound in high purity and yield, by the reaction of a trialkylaluminum salt of a long-chain fatty acid with a trialkylamine-sulfur trioxide complex, in the presence of a solvent at a low temperature. CONSTITUTION: A trialkylaluminum salt of a long-chain fatty acid expressed by formula I (R is 11W17C alkyl; R' is 1W4C alkyl) is reacted with a trialkylamine- sulfur trioxide complex in the presence of a solvent, e.g. 1,2-dichloroethane, at a low temperature of -5 to 25°C, to give a trialkylaluminum salt of a mixed long- chain fatty acid-sulfuric acid anhydride expressed by formula III. The complex of formula II is obtained by the reaction of a trialkylamine with sulfur trioxide in a solvent. Lauric, myristic or palmitic acid may be cited as the long-chain fatty acid used in the compound expressed by formula I, and trimethyl- or triethylamine may be cited as the trialkylamine.
