Preparation |
The preparation of 2-Ethyl-2-adamantyl methacrylate is as follows:Add 2175ml of n-hexane to the 3L four-necked flask equipped with stirring paddle, condenser tube and thermometer, turn on stirring, add 97g of 2-ethyladamantanol to the system, and slowly add 0.0072g of polymerization inhibitor tetrachlorobenzoquinone to the reaction system , add 72.5g of basic ion exchange resin, adjust pH=7-8, cool down to -10°C, slowly add 72.5g of vinyl methacrylate dropwise to the reaction system, keep the reaction for 6h, monitor the reaction progress, take a sample to detect the reaction is complete After adding 800 ml of water to the reaction system, stirring and extracting the phases, the organic phase was dried, concentrated under reduced pressure and evaporated to dryness to obtain 125 g of 2-ethyl-2-adamantyl methacrylate product with a yield of 93.45%. |
