Embodiment 1

[0011] (1) Preparation of 3-(N-methyl-N-hydroxyethylaminomethyl)indole

[0012] In a 250ml four-necked flask, add 0.2 moles of N-methylethanolamine, dropwise add 0.5 moles of glacial acetic acid at a temperature below 5°C, and slowly add dropwise an aqueous solution containing 0.2 moles of formaldehyde at a temperature of 5-10°C. Continue to stir for 0.5 hours after the dropwise addition, and then add 0.2 moles of indole in batches. After the addition, raise the temperature to 30°C and keep it warm for 7 hours, then lower the temperature and keep it below 5°C, and adjust the pH to 11 with 40% NaOH solution. Filter, wash the filter cake with ice water until the filtrate pH = 7, recrystallize the filter cake with absolute ethanol, dry at 50°C, and pulverize it. After elemental analysis and infrared spectroscopic analysis, the product obtained is 3-(N- Methyl-N-hydroxyethylaminomethyl) indole, productive rate is 88.2%, and its reaction formula is as follows:

Embodiment 2

[0018] Same as Example 1, except that acrylic acid chloride was replaced by methacryloyl chloride to obtain 3-(N-methyl-N-methacryloyloxyethylaminomethyl)indole functional monomer with a yield of 87.2%.

Embodiment 3

[0020] With embodiment 1, just change indole into 7-nitroindole, obtain 7-nitro-3-(N-methyl-N-acryloyloxyethylaminomethyl) indole functional monomer, yield was 85.6%.

Abstract

The invention relates to an acrylic ester functional monomer containing a donaxine structure and a preparation method thereof. The prepared functional monomer and other monomers containing alkenyls have a copolymerization reaction, so that polypropylene or polyethylene organic resin with the sterilization function can be prepared. The organic resin with the sterilization function has higher molecular weight, so that the organic resin cannot diffuse or run off easily during application; and organic resin can release a sterilizing agent uniformly through hydrolysis of ester groups, so that the sterilizing agent can be used efficiently. The acrylic ester functional monomer and the preparation method thereof have great significance for development of novel marine antifouling coatings.

Description

technical field [0001] The invention relates to a functional acrylic ester monomer, in particular to an acrylic ester functional monomer with a bactericidal function and containing aditropine structure and a preparation method thereof. Background technique [0002] Phylloline, also known as graminine and 3-dimethylaminomethylindole, is an allelopathic alkaloid produced by plants such as barley during the evolution process, and has a strong effect on environmental plants, insects, microorganisms, etc. Growth inhibitory effect. Owing to the characteristics of high efficiency, low toxicity, low resistance, and low residue of anophylline biopesticides, it has become a class of biopesticides with broad development prospects. In addition, Phylloline compounds have strong biocidal properties, and during the process of organisms attaching, they first secrete a large amount of biological mucous membranes containing a large number of bacteria and other microorganisms, and rely on the...
