GLYCERYL TRIMETHACRYLATE synthesis

5synthesis methods
-

Yield: 32%

Reaction Conditions:

with sodium hydride in hexane at 20;Solvent;

Steps:

2 Example 2
Sodium hydride (3.05 g, 70 mmol) 55% in liquid paraffin was subjected to cleaning with hexane, and the liquid paraffin was removed. After removing the liquid paraffin, 150 mL of hexane was added to sodium hydride at room temperature and stirred. Then, glycerin-1,3-dimethacrylate (15.98 g, 70 mmol) was slowly dripped into the above-described mixture of sodium hydride and hexane at room temperature. Then, precipitated 10.8 g of white solid precipitate was removed by filtration. Next, by employing a rotary evaporator, hexane was removed from the filtrate (i.e., the mixture of sodium hydride, hexane, and glycerin-1,3-dimethacrylate after filtration). Accordingly, glycerin trimethacrylate as shown in <> was obtained. Obtained amount was 6.6 g (yield is 32%). Measurement data of 1H-NMR and IR was the same as example 1.
