Usage

Synthesis

The synthesis of?2-Methyl-2-adamantylmethacrylate is as follows:Add 3546ml of n-heptane in the 5L four-necked flask equipped with stirring paddle, condenser tube and thermometer, turn on stirring, add 126.3g of 2-methyladamantanol to the system, and slowly add 0.022g polymerization inhibitor tetrachlorobenzoquinone to the reaction, add 110.8g basic ion exchange resin, adjust pH=7-8, cool down to -13°C, slowly add 110.8g vinyl methacrylate dropwise to the reaction system, keep the reaction for 7h, monitor the reaction progress, and take samples for detection After the reaction was completed, 1000 ml of water was added to the reaction system, and the mixture was stirred and extracted for phase separation. The organic phase was dried, concentrated under reduced pressure and evaporated to dryness to obtain 167 g of 2-methyl-2-adamantyl methacrylate product with a yield of 93.78%.

Method for synthesizing adamantyl (meth) acrylate

The invention discloses a method for synthesizing adamantyl (meth) acrylate, and relates to the field of organic synthesis. The method for synthesizing adamantyl (meth) acrylate comprises the steps: 1, reacting (methyl) acrylic acid with alkyl sulfonyl chloride to generate mixed anhydride S1; 2, reacting 2-adamantanone with halogenated alkane under the action of a lithium reagent or a Grignard reagent to generate an intermediate S2; and 3, reacting the mixed anhydride S1 with the intermediate S2 to generate the adamantyl (meth) acrylate. The invention provides a synthetic method of adamantyl (meth) acrylate, and provides more selectivity for synthesis of adamantyl (meth) acrylate. The synthesis method disclosed by the invention is high in yield, high in product purity and low in synthesis cost.

Adamantyl ester monomer composition

The present invention discloses an adamantyl ester monomer composition characterized by containing at least an adamantyl ester monomer having at least one polymerizable unsaturated bond in the molecule, and a compound represented by the following general formula (1): (in the formula, R1 is an alkyl group of 1 to 5 carbon atoms, R2 is an alkyl group of 1 to 5 carbon atoms, R3 is a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, and R4 is a hydrogen atom or a methyl group). The composition has high storage stability and, by subjecting it to distillation, an adamantyl ester monomer of high purity can be obtained easily.

Process for preparing acrylate compound

An acrylate compound of formula (4): 1is produced by allowing an acrylic acid compound of formula (1): 2to react with an unsaturated compound of formula (2) or (3): 3In formulae (1) through (4), R1 and R2 are H or F, R3 is H, F, or an alkyl, alkenyl, fluoroalkyl or fluoroalkenyl group, R4 and R5 are H, halogen, or an alkyl, alkenyl, halogenated alkyl or halogenated alkenyl group; and X and Y are an unsubstituted or substituted hydrocarbon group, and dashed line - - - - - means that X and Y may be bonded together to form a cyclic structure.
