production method | with the help of a glass tube with a diameter of 10-12mm, A 2L reaction bottle A was connected to A serpentine condenser B (see Fig. 3), and the condenser outer sleeve C was filled with ice water. A thick glass tube (3.5 in diameter) connected at the lower end of the condenser was inserted into a 4.5 hard glass flask D as a receiver, the diameter of which was about. 250ml of ether was added to the receiver D so that the lower end of the coarse glass tube was about 2.5cm from the ether level. The tube must have the appropriate aperture and position to effectively prevent clogging by ice. The entire receiver was cooled in a dry ice-acetone bath E and the other outlet tubes therein were connected to a water pump and a barometer. In A 2L reaction bottle A, place 550ml of ammonia water with A concentration of about 1.5mol/L (the exact concentration is needed) and cool to 0 ° C, 1.5g of crushed ice and ml of a sodium hypochlorite solution at a concentration of mol/L were added, and the reaction bottle was immediately connected to the entire apparatus. The water pump was started, adjusted to a vacuum level of 2.00 to 3.333kpa, and the distillation was maintained in a hot water bath at 40 to 45 ° C., and the distillate obtained contained 150 to 170g of water in 50 to 60min. Stop the distillation, immediately pour the ether solution from water-frozen ice in receiver D into a container cooled in a dry ice-acetone bath (a large glass tube 4-5cm in diameter and 30-35cm in length is appropriate, it can be easily stored in a Dewar), and the resulting 160-ether solution contains about 0.18mol of ammonia chloride. Then, about 70ml of diethyl ether was added to a flask D in which ice remained, and the flask was allowed to penetrate into warm water below 40 ° C. To dissolve the ice. When the ice is just melted and the solution is still cold, the ether is separated and freeze-dried for several minutes, then filtered through cotton balls and combined with the previous solution of chloroammonia in ether to obtain 230 ~ 250ml, it usually contains 0.25mol of ammonia chloride. |
