How to make silicone oil diluted and completely dissolved in lubricating oil?
Put the clean and dry four-necked flask into the heating mantle, and connect the stirrer, condenser and thermometer respectively. Use the catalyst quantitatively in the urban area of the analytical balance, and use the measuring cup to remove the quantitative dimethyl silicone oil, hydrogen-containing silicone oil, methyl phenyl silicone oil, and reaction solvent. The above solvents were added to the four-necked flask in turn, the cooling water was turned on, and the heating mantle switch was turned on. After reacting for a period of time, start stirring, adjust the electric heating to the maximum, and change the spherical condenser tube from the vertical direction to the oblique downward position, and connect the side-pass glass elbow and the conical flask to facilitate recovery and distillation. solvent. When the solvent is about to be distilled, turn on the vacuum pump and continue to heat up. The reaction is carried out for a period of time, and the low boilers are removed by distillation under reduced pressure to obtain the product
