Embodiment 1-1
[0031] Add n-bromopropane and isopropanol into the distillation bottle of the distillation device according to the mass ratio of 1:1, then start distillation, and observe the temperature change indicated by the thermometer at the outlet of the distillation bottle during the boiling distillation process. During the distillation process, the temperature indicated by the thermometer gradually increased. When the temperature of the thermometer is around 68°C, the mixed solution boils, and a large number of liquid droplets drip out from the tail joint. With the distillation of the distillate, the liquid droplets at the tail joint begin to decrease again, and then the temperature of the thermometer continues to rise. The temperature was raised to 83°C and stabilized, and then a large number of liquid droplets dripped out from the tail joint. Among them, through multiple tests, it was found that when the temperature was raised to 83°C, the weight of the distillate accounted for 65% of ...
Embodiment 1-2
[0033] On the basis of Example 1-1, it can be concluded that n-bromopropane and Virahol can form an azeotropic composition, and the mass combination ratio of n-bromopropane and Virahol azeotropic mixture can be obtained by the ratio of the effluent It is 82.5:17.5, and this embodiment is further verified on the basis of embodiment 1-1.
[0034] Add n-bromopropane and isopropanol into the distillation bottle of the distillation device according to the mass ratio of 82.5:17.5, then start distillation, and observe the temperature change indicated by the thermometer at the outlet of the distillation bottle during the boiling distillation process. During the distillation process, the temperature indicated by the thermometer gradually increased. When the temperature of the thermometer is around 68°C, the mixed solution boils, and a large number of liquid droplets drip out from the tail joint until all the liquid is distilled off.
[0035] Therefore, the optimal ratio of the cleanin...
Embodiment 1-3
[0037] Taking the cleaning laser particle size analyzer as an example, the toner sample is measured with an uncleaned laser particle size analyzer. For the specific particle size distribution diagram, see the attached figure 1 .
[0038] Cleaning the laser particle size analyzer: the azeotropic composition is placed in a closed blue cap ultrasonic bottle, passed through an ultrasonic stirrer in the Stir for 30 to 45 minutes at a high power, then add it to the sprayer, and then spray the cleaning agent on the outer surface of the light-transmitting lens through the sprayer, and then use a dust-free cloth to gently brush over the cleaning area to absorb large particles of liquid droplets, and then The small particle droplets evaporate naturally, and the cleaning process is completed. At the same time, connect the internal circulation system with the water inlet pump, and then send the cleaning agent to the internal circulation system through the water inlet pump, then run 3 cy...
