FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to the improved method for preparing cyclohexyl nitrate. Invention describes a method for preparing cyclohexyl nitrate by treatment of cyclohexanol with nitric acid and acetic anhydride in the presence of additive in the molar ratio of reagents = 1:(1-1.5):(1-1.5), respectively. For treatment cyclohexanol containing 1-5 wt.-% of cyclohexyl nitrate and/or water is taken and process is carried out with continuous feeding reagents by parallel flows. Method provides enhancing quality of the end product, simplified technology and development of the more safe method for manufacturing.
EFFECT: improved preparing method.
