Other usages as below

1) Acetic acid (3-methoxybutyl) ester can be used as a synthesis method for the intermediate 2-butyraldehyde, including the following steps:

A: Add 2mol of 1-bromo-2-butyne and 900ml of anhydrous butyl ether solution to the reaction vessel, control the stirring speed at 130rpm, control the solution temperature to 10 ℃, and add 2mol of lanthanum oxide powder in batches for 90 minutes of reaction;

B: Then add 2mol of anhydrous acetic acid (3-methoxybutyl) ester solution, raise the solution temperature to 20 ℃, react for 50min, add 1.3L of anhydrous 2,4-dimethylsulfolane solution, reflux for 2h, wash with anhydrous N, N-dimethylacetamide solution 2 times, wash with anhydrous diethylene glycol dimethyl ether solution 4 times, recrystallize in anhydrous dihexylamine solution, dehydrate with anhydrous potassium carbonate dehydrator, and obtain 116.96g of finished 2-butanal with a yield of 86%.

2) Preparation of resin (A-1):

Firstly, add 235g of bisphenol fluorene type epoxy resin (epoxy equivalent 235), 110mg of tetramethylammonium chloride, 100mg of 2,6-di-tert-butyl-4-methylphenol, and 72.0g of acrylic acid to a 500ml four necked flask. Blow in air at a rate of 25ml/minute and heat to dissolve at 90-100 ℃. Then, slowly heat up the solution in a white and turbid state to 120 ℃ to completely dissolve it. At this point, the solution gradually becomes transparent and viscous, and continues to stir while still in place. Measure the acid value during this period and continue heating and stirring until it is less than 1.0mgKOH/g. It takes 12 hours before the acid value reaches the target value. Afterwards, it was cooled to room temperature to obtain a colorless, transparent, and solid bisphenol fluorene type epoxy acrylate. Then, 600g of acetic acid (3-methoxybutyl) ester was added to 307.0g of the obtained bisphenol fluorene type epoxy acrylate and dissolved. Then, 80.5g of benzophenone tetracarboxylic anhydride and 1g of tetraethyl ammonium bromide were mixed, and the temperature was slowly raised. The reaction was carried out at 110-115 ℃ for 4 hours. After confirming the disappearance of the anhydride group, 38.0g of 1,2,3,6-tetrahydrophthalic anhydride was mixed and reacted at 90 ℃ for 6 hours to obtain resin (A-1).
