Reaction Conditions:
with sodium carbonate;sodium hydroxide in water at 100 - 105; for 8 h;Autoclave;
Steps:
3 Example 3
To an autoclave equipped with a stirrer, 356 g of ethylene glycol monobutyl ether and 19 g of water were added 150 g (0.657 mol) of 2,2'-bis (4-hydroxyphenyl) propane (hereinafter referred to as bisphenol A), 53 g (1.325 mol) of sodium hydroxide and 14 g (0.132 mol) of sodium carbonate were added in sequence. Subsequently, 121 g (1.581 mol) of allyl chloride was added and the mixture was reacted by heating at 100 to 105 DEG C for 8 hours while keeping the mixture in a sealed state. After the completion of the reaction, allyl chloride was distilled off in the same manner as in Example 1, and a water separation was performed. After neutralization, thermal treatment was performed to obtain an ethylene glycol monobutyl ether solution of bisphenol A diallyl ether. The reaction solution had an Na content of about 10 ppm. The HPLC composition ratio (area percentage) was 95.0% for 2,2-bis (4-allyl hydroxyphenyl) propane, 0.2% for bisphenol A, and 4-hydroxyphenyl-4'-allyl hydroxyphenylpropane Bisphenol A monoallyl ether) was 2.2%. The yield calculated from the content of bisphenol A diallyl ether was 95%.The reaction solution (filtrate) after the thermal filtration was injected into an autoclave and the heating potential reaction was carried out at 195 to 200 in a closed state (0.1 MPaG) for 7 hours. Thereafter, ethylene glycol monobutyl ether was distilled off under reduced pressure at 150 to obtain 166 g of 2,2'-bis (3-allyl-4-hydroxyphenyl) propane (hereinafter referred to as diallyl-bisphenol A) Yield: 82%). The obtained diallyl-bisphenol A had a HPLC composition ratio (area percentage) of 92.0%.
