Embodiment 1
[0025] The hydrogen-containing silicone oil (hydrogen content 1.59%) produced by Zhejiang Hengyecheng Silicone Co., Ltd. was used as the standard sample. Weigh 0.5021g of the standard sample and place it in a 250mL single-port reaction bottle, then measure 60mL of potassium hydroxide solution with a mass fraction of 30% and add it to a 100mL constant pressure dropping funnel, press figure 1 Connect the experimental device well and pay attention to sealing. Start the magnetic stirrer, and drop the liquid in the constant pressure dropping funnel into the single-necked flask at a constant speed. After the reaction was completed, the volume of hydrogen collected was 167 mL. Repeat the test of the standard sample twice, and collect hydrogen volumes of 176mL and 174mL respectively.
[0026] The hydrogen-containing silicone oil produced by Zhejiang Chuangji Silicone Materials Co., Ltd. was used as the standard sample. Weigh 0.5021g of the sample to be tested and place it in a 250m...
Embodiment 2
[0032] Compared with Example 1, the potassium hydroxide solution consumption is changed to 40%, and other conditions remain unchanged.
Embodiment 3
[0034] Compared with Example 1, the mass fraction of potassium hydroxide solution was changed to 80mL, and other conditions remained unchanged.
