Embodiment 1
[0019] This embodiment discloses a kind of preparation method of cyclohexyl nitrate, comprises the following steps:
[0020] Step 1, add a certain amount of 98% concentrated sulfuric acid in the four-necked flask equipped with agitator, low temperature thermometer, air condenser and dropping funnel, add dropwise 65% concentrated nitric acid under vigorous stirring, then add dropwise a certain amount of Cyclohexanol——chloroform solution, after adding, react for 20-25min;
[0021] Step 2. Pour the reaction mixture into ice water, separate the organic phase, extract the aqueous phase twice with 45-55 mL chloroform, and combine with the above organic phase;
[0022] Step 3, the organic phase is washed with an aqueous solution of sodium carbonate, then washed with water until neutral, and finally dried with anhydrous sodium sulfate;
[0023] Step 4, under normal pressure, distill out chloroform to obtain crude product, then distill under reduced pressure to obtain pure cyclohexyl ...
