uses | pharmaceutical intermediates for the production of guanethidine. |
Production method | First, cyclohexanone and nitromethane are added, and then reduced with iron powder. Add methanol, nitromethane and cyclohexanone into the reaction tank, stir, control the temperature at 5-10 ℃, add sodium hydroxide solution dropwise, finish adding, cool to -4 ℃, stir for 1h, centrifuge and filter. The filtrate recovers methanol, the filter cake is dissolved in water, acidified with acetic acid to pH4-5 at 10 ℃, heated to 30 ℃ to completely dissolve, and the oil layer is divided to obtain nitromethylcyclohexanol. When the reduction operation is carried out, water, iron powder and 2/3 hydrochloric acid in the total amount are first added to the reaction tank, the pH5-6 is controlled, the temperature is 40-50 ℃, the crude nitromethylcyclohexanol oil is obtained by dropping one step, and the temperature is kept and stirred after adding, add 1/6 hydrochloric acid every 1 hour, add 1/3 of the total hydrochloric acid in 2 times, maintain pH5-6, continue stirring for 2 hours, and then filter while hot. The filtrate is amine methylcyclohexanol salt solution. |
