Detailed Description
The invention will be better understood from the following examples.
Example 1
Preparation of compound A diethylene glycol diglycidyl ether di-pyrogallic acid ether:
12.50g (0.1 mol) of pyrogallic acid (molecular weight 125.01) and 8.73g (0.04 mol) of diethylene glycol diglycidyl ether (molecular weight 218.25) were dissolved in 250g of isopropanol, and 0.15g of boron trifluoride diethyl ether as a catalyst was added thereto, heated to 90℃and reacted for 8 hours. After cooling, pH was adjusted to neutrality with 5% hydrochloric acid solution, the impurities were removed by filtration, and the product was obtained by column chromatography separation, concentration and crystallization in a yield of 12.0 g and 68% (based on diethylene glycol diglycidyl ether). The infrared spectrum of the product is shown in figure 1.
Preparation of compound B, di-pyrogallic acid diethylene glycol dicarbonate:
after 12.50g (0.1 mol) of pyrogallic acid and 9.24g (0.04 mol) of diethylene glycol bischloroformate (molecular weight 231.03) were dissolved in 250g of isopropanol, 2.12g of sodium carbonate as a neutralizing agent was added, 1.2g of anhydrous magnesium sulfate as a drying agent was added, and the reaction time at-5℃was 6 hours. The solids were removed by filtration and separated by column chromatography to give 12.2 g of the product in 69% yield (based on diethylene glycol bischloroformate).
