Embodiment 1
[0110] Example 1 Preparation of 1,3-bis-(4-phenoxyphen)oxy-2-propyl acrylate (chemical formula is as follows)
[0111]
[0112] (1) Preparation of 1,3-bis-(4-phenoxyphen)oxy-2-propanol
[0113] 4-phenoxyphenol (76g, 0.41mol), potassium carbonate (56g, 0.4mol) and absolute ethanol (200mL) were successively added to the three-necked flask, the mixture was refluxed and stirred for 1h, and 1,3- Dichloro-2-propanol (13 g, 0.1 mol), and stirring at reflux was continued for 24 h. The reaction solution was cooled to room temperature, evaporated to remove ethanol, dissolved in dichloromethane (300 mL), filtered to remove inorganic salts, and the filtrate was washed with aqueous sodium hydroxide solution (10% wt, 100 mL×6). The organic phase obtained after washing was dried with anhydrous sodium sulfate for 2 h, filtered, and the solvent was removed by rotary evaporation to obtain a white solid (27 g, yield 63%). Mass spectrometry and NMR H spectrum test data are as follows:

Embodiment 2
[0120] Example 2 Preparation of 1,3-bis-(4-phenoxyphen)oxy-2-propyl methacrylate (chemical formula is as follows)
[0121]
[0122]1,3-bis(4-phenoxyphen)oxy-2-propanol (4.89g, 11mmol), triethylamine (2.4g, 24mmol), 4-dimethylaminopyridine ( 0.28 g, 2.3 mmol) and tetrahydrofuran (70 mL), after fully dissolving, methacryloyl chloride (1.8 g, 17 mmol) was slowly added dropwise thereto, and stirring was continued for 24 h. The reaction solution was filtered, the tetrahydrofuran was removed by rotary evaporation, and the solution was dissolved in dichloromethane (200 mL), and aqueous sodium hydroxide solution (5% wt, 80 mL) was added and stirred for 0.5 h. After liquid separation, the solvent was removed by rotary evaporation, and the product was subjected to column chromatography (n-Hex / EA 20:1) to obtain a white solid (3.2 g, yield 58%). Mass spectrometry and NMR H spectrum test data are as follows:
[0123] LC-MS (ESI, pos.ion) m / z: 519 [M+Na] + ;
[0124] 1 H NMR (400...
Embodiment 3
[0125] Example 3 Preparation of 1,3-bis-(4-benzylphenyl)oxy-2-propyl acrylate (chemical formula is as follows)
[0126]
[0127] (1) Preparation of 1,3-bis-(4-benzylphenyl)oxy-2-propanol
[0128] 4-benzylphenol (25g, 135.8mmol), potassium carbonate (47g, 338.1mmol) and absolute ethanol (200mL) were successively added to the three-necked flask, the mixture was stirred at reflux for 1h, and 1,3- Dichloro-2-propanol (5.5 g, 42.6 mmol) and continued stirring at reflux for 24 h. The reaction solution was cooled to room temperature, ethanol was removed by rotary evaporation, dissolved in dichloromethane (300 mL), the inorganic salt was removed by filtration, and the filtrate was washed with aqueous sodium hydroxide solution (10% wt, 100 mL×6). The organic phase was dried with anhydrous sodium sulfate for 2 h, filtered, and the solvent was removed by rotary evaporation to obtain a white solid (14 g, yield 77%). Mass spectrometry and NMR H spectrum test data are as follows: ...
