Embodiment 1
[0098] The molar ratio of isomeric carbooctaol (2-EH alcohol) and allyl glycidyl ether is 1 / 1.05, and 200g of 2-EH alcohol (measured hydroxyl value 431.5mgKOH / g) is weighed up to the standard (<1000ppm) ) into the reaction kettle, add 0.9gNaH, under the protection of nitrogen, stir and heat up to 90°C. Slowly add a total of 184.5 g of allyl glycidyl ether to the reaction kettle dropwise, the dropwise addition is completed within 1 hour, continue to stir for 8 hours, cool down to 50-60°C, and take a sample of 1-1#.
Embodiment 2
[0100] Referring to the method of Example 1, the molar ratio of 2-EH alcohol to allyl glycidyl ether is 1 / 1.05. Weigh 250g of 2-EH alcohol into the reaction kettle, add 1.13g of NaH, stir and raise the temperature to 90°C under the protection of nitrogen. Slowly add a total of 230.1 g of allyl glycidyl ether dropwise to the reactor, and the dropwise addition is completed within 1 hour, continue to stir and react for 4 hours, and sample 1-2#-1 sample; continue to stir and react for 8 hours, and sample as 1-2#-2 samples.
Embodiment 3
[0102] Referring to the method of Example 1, the molar ratio of 2-EH alcohol to allyl glycidyl ether is 1 / 2.0. Weigh 300g of 2-EH alcohol into the reaction kettle, add 1.35g of NaH, stir and raise the temperature to 80°C under the protection of nitrogen. Slowly add 526.8g of allyl glycidyl ether dropwise to the reaction kettle, the dropwise addition is completed within 1 hour, continue to stir and react for 4 hours, cool down, take a sample of 1-3#-2, continue to stir for 8 hours, and take a sample of 1-3#-1 sample.
