Basic Info

What is Vinylimidazole?

1-Vinylimidazole is a water-soluble fundamental monomer that can be polymerized with a selection of vinyl as well as acrylic monomers by free radicals to create quaternizable homopolymers. The product is a functional copolymer utilized as an additive in oilfield chemicals and cosmetics. 1-Vinylimidazole is made use of as a reactive diluent in UV paints, inks and adhesives.

1-Vinylimidazole is a very important imidazole derivative and an important great chemical resources. It is primarily made use of in the synthesis of medicines as well as pesticides and as a healing representative for epoxy resins. It can also be used to prepare vinylimidazole ionic liquids. It is easy to polymerize into a plastic rubber polymer. It is used as a hardener for resin materials, as the nucleus of photosensitive chemical reagent resin inclusions, and also used in the petroleum industry and as a high polymer. With the continuous upgrading of my country’s industrial technology, the demand for 1-vinylimidazole will increase day by day, so the preparation of 1-vinylimidazole has great economic value and social significance.

Vinylimidazole Uses

In the process of ethylene lithium catalyzed by isoprene, the vinyl group is removed.

It is used as hardener of resin product, photosensitive chemical reagent, core of resin incorporation, as well as likewise used in oil sector and as high polymer; Eliminator of plastic security group in the process of catalytic lithification with isoprene.

1-Vinylimidazole is used as a monomer in the synthesis of molecularly imprinted polymers. The invention relates to the removal of vinyl protective groups through the lithium process catalyzed by isoprene. In addition, it also participated in the preparation of magnetic poly (divinylbenzene-1-vinylimidazole) microspheres. It is further used to prepare ion imprinted polyethylene imidazole-silica hybrid copolymer.

1-Vinylimidazole is a heterocyclic compound, which is generally utilized in the synthesis of medication and chemicals, as well as the treating agent of epoxy material. It can also be used to prepare vinylimidazole ionic fluids, which can be quickly polymerized into plastic rubber polymers. It is utilized as the setting agent of material materials, photosensitive chemical reagent, the core of resin additions, as well as also utilized in the oil market and as a high polymer.

1-Vinyl imidazole has been used:

  • As a functional monomer in the synthesis of molecularly imprinted polymers
  • As a monomer for preparing magnetic poly (divinylbenzene-1-vinylimidazole) [mesopolymer (DVB-VIM)] microspheres
  • In the synthesis of a novel ion-imprinted polyvinylimidazole-silica crossbreed copolymer (IIHC)
  • Removal of vinyl protection groups by isoprene catalyzed lithification process

Application of Vinylimidazole

1-Vinyl imidazole is used as an energetic diluent in UV paints, inks, layers as well as varnish adhesives because of its high sensitivity to free radical (UV) polymerization. It is additionally utilized to functionalize the polymer surface area via UV-induced implanting to boost wettability and attachment.

The copolymer of N-vinylimidazole quaternary ammonium salt and polar monomer (especially N-vinylpyrrolidone) is a cationic polyelectrolyte, which is particularly suitable for use as a flocculant for water treatment, a flotation aid for coal and ore processing, a drilling fluid additive, and the extraction of oil, as a lotion cutting agent for lotion dehydration of crude oil in refineries, and as a corrosion inhibitor for ferroalloys.

The copolymer of N-vinylimidazole quaternary ammonium salt and polymerizable unsaturated carboxylic acid (such as methacrylic acid or sulfonic acid, such as 2-acrylamido-2-methylpropane sulfonic acid) can reduce the static charge of hair, so it can be used in shampoo to improve wet comb rationality.

1-Vinylimidazole undergoes radical polymerization in aqueous solution or alcohol solution to form a homopolymer with an average molar mass of 2000 to 50000. However, it usually still contains relatively high residual monomer content (>600 ppm). The unwanted recurring material of N-vinylimidazole can be lowered to less than 50 ppm by adding sulfur-containing chain modifiers, such as mercaptoethanol, although the molar mass of the acquired polymer is likewise reduced.

The hydrogel from poly-1-vinylimidazole successfully binds a great deal of heavy metal ions (besides Pb 2+), which can uniquely and quantitatively elute from the hydrogel.

1-Vinylimidazole can be totally free radical copolymerized with a selection of vinyl as well as acrylic monomers. The water-soluble copolymer with vinyl pyrrolidone is made use of as a color transfer prevention in cleaning agent preparations,

Vinyl acetate is used as the coating of the lithographic plate, and acrylate or methacrylate or 2-hydroxyethyl methacrylate is used as the adhesion promoter in the coating or acrylonitrile is used as the precursor of carbon fiber.

Preparation of Vinylimidazole

Add 34.0g of imidazole, 28.0g of potassium hydroxide, 34.5g of potassium carbonate, and 50.0g of deionized water into a 500mL three-necked flask equipped with a thermometer and an electric stirrer, heat up, stir, and keep the reaction temperature at 60°C 1.5h, stop heating and stirring;

After the reaction, the solution was slowly added dropwise to a 1000mL four-neck flask (where 24.8g dichloroethane and 11.5g absolute ethanol were housed) equipped with a reflux condenser, a gas absorber, a thermometer, and an electric stirrer, and the temperature was raised slowly. Stir, the reaction temperature is 60°C, and after maintaining the reaction temperature for 1.0h, continue to heat up to 70°C, maintain the reaction temperature for 2.0h, stop heating, and continue stirring;

After the temperature drops to 40°C, slowly add 14.0g of potassium hydroxide to the four-neck flask (into 2 times, 7.0g each time), continue to heat slowly to 80°C, keep the reaction temperature for 2.0h, stop heating and stirring , after being cooled to room temperature, suction filtration, the filtrate is subjected to vacuum distillation (vacuum degree 0.06MPa, temperature 85 ℃) after 1.0h, the fraction obtained by cooling is poured out, continue to heat up to 105 ℃ and carry out vacuum distillation (vacuum degree 0.06MPa), the distillate obtained by cooling through the condenser tube is light yellow 1-vinylimidazole, the yield is 85.5%, and the content is 99.6%.
