Abstract:
1. A method for producing adamantyl (meth)acrylates of formulae (3) and (4), comprising a reaction step of reacting a compound of formula (1) with a (meth)acryloyl halide or a (meth)acrylic anhydride in a reaction solution to give a mixture of compounds of formulae (2) to (4), and a separation step of separating the mixture of compounds of formulae (2) to (4); wherein the separation step comprises an extraction step of extracting compounds of formulae (2) and (3) from the reaction solution with a mixed solvent of water and a polar organic solvent, thereby giving a water/polar organic solvent solution containing the compounds of formulae (2) and (3) and the mixed solvent, and a back-extraction step of back-extracting the compound of formula (3) from the water/polar organic solvent solution with a non-polar organic solvent: wherein X's are the same or different, each representing a hydrogen atom, an alkyl group, a halogen-containing alkyl group, a halogen group, a nitrile group, or an ether group; n indicates an integer of 14; R wherein X's are the same or different, each representing a hydrogen atom, an alkyl group, a halogen-containing alkyl group, a halogen group, a nitrile group, or an ether group; n indicates an integer of 14; and R wherein X's are the same or different, each representing a hydrogen atom, an alkyl group, a halogen-containing alkyl group, a halogen group, a nitrile group, or an ether group; n indicates an integer of 14; R wherein X's are the same or different, each representing a hydrogen atom, an alkyl group, a halogen-containing alkyl group, a halogen group, a nitrile group, or an ether group; n indicates an integer of 14; R
