    Abstract: Nitrite esters of alkanols and cycloalkanols are prepared by treating the alcohol with a solution of nitrosylsulphuric acid in aqueous sulphuric acid and separating the resulting ester from the mixture containing sulphuric acid, ester, alcohol and water. The resulting sulphuric acid solution may be freed from alcohol, concentrated and reacted with nitrous gases to yield fresh nitrosylsulphuric solution. Specified esters are methyl-, ethyl-, butyl-, amyl- and cyclohexyl-nitrates. The process is illustrated by reference to diagrammatic flow sheets (not shown).

    Abstract translation: 通过用亚硝酰基硫酸在硫酸水溶液中处理醇,并将所得酯与含有硫酸,酯,醇和水的混合物分离,制备链烷醇和环烷醇的亚硝酸酯。 所得到的硫酸溶液可以不含酒精,浓缩并与亚硝基气体反应产生新鲜的亚硝酰基硫酸溶液。 指定的酯是甲基 - ,乙基 - ,丁基 - ,戊基 - 和环己基 - 硝酸酯。 该过程通过参考图示流程图(未示出)进行说明。
