    Hydroxyethyl acrylate is used as an additive for lubricating oil washing in the oil and fat industry, and as a dehydrating agent for electron microscopes in the electronics industry. Adhesives used in the textile industry to manufacture fabrics. In addition, it is used as a chemical reagent in analytical chemistry and also as an embedding agent for water solubility. Place 108g (1.5mmol) of acrylic acid, 88g (2mol) of ethylene oxide, and 2g (0.019mol) of triethylamine used for the production of 2-hydroxyethyl acrylate in a 1L high-pressure vessel, heat at 70 ℃, and stir for 12 hours. After heating, cool it to room temperature, and then distill the resulting reaction mixture under reduced pressure (64 71 ° C/0.3KPa) to obtain 164g (1.41mol; yield 94%) of hydroxyethyl acrylate. Hydroxyethyl acrylate is used as an active diluent and crosslinking agent in radiation curing systems, as well as as as a resin crosslinking agent, plastic, and rubber modifier.

  • 2-hydroxy ethyl methacrylate CAS: 868-77-9

    2-hydroxy ethyl methacrylate CAS: 868-77-9

    Hydroxyethyl methacrylate (HEMA) is a non-toxic, harmless, and widely used reagent, commonly used for soft lens materials, lens materials, or as a monomer for preparing dense ceramics and glass. Polyhydroxyethyl methacrylate (PHEMA) is a promising biopolymer with significant inertness, biocompatibility, and insolubility. Method 1: Place 100 ml of toluene, 62.1 (1 mol) parts of ethylene glycol, and enzymes (Novozym 435, 0.04 parts, 0.01 parts of sodium carbonate, and 0.01 parts of hydroquinone manufactured by Novo) into a 1-liter glass flask connected to a cooling tube receiver (for measuring moisture) and a reflux side tube, and heat to 40 ° C. 72.1 parts (1mol) of acrylic acid were added in batches within 10 minutes, while stirring step by step. After completing the total addition, the mixture was stirred at the same temperature under reduced pressure of 10mPa. After the reaction, the target acrylate was obtained by filtering and separating the catalyst and additives. The time required for the reaction is approximately 6 hours. The yield and composition of the obtained acrylate were determined by gas chromatography (hereinafter abbreviated as GC). [0044] [Example 2] [0045] Except for changing 72.1 parts (1 mol) of acrylic acid to 86.1 parts (1 mol) of methacrylic acid in Example 1, the target compound was obtained in a similar manner to Example 1. The time required for the reaction is approximately 5 hours. The yield of hydroxyethyl methacrylate (HEMA) was 98.5% by gas chromatography. The synthesis is continuous as shown in Figure 1. Method 2: Add 31.05g ethylene glycol (EG, 0.5mol), 47.35g (0.55mol) methacrylic acid, 40g (inside, 22g water in the catalyst before use, 18g dry weight) strong acid ion exchange resin (Amberlite IR124: gel type, 12% cross-linking degree, no pore), 0.086g HO-TEMPO, 0.086g hydroquinone and 200g toluene into a 500ml glass flask equipped with Dean Stark device, cooling pipe, thermometer and air inlet pipe, Then heat and stir at 100 ℃, while using a pump to add water at a rate of 2g/h. The water formed in the reaction is azeotropic with toluene and removed through the Dean Stark device. After 5 hours, the conversion rate of hydroxyethyl methacrylate was 87.3%. The synthesis is continuous as shown in Figure 1. purpose Hydroxyethyl methacrylate is mainly used for modifying resins and coatings. Copolymerization with other acrylic monomers can produce acrylic resins with active hydroxyl groups in the side chains, which can undergo esterification and crosslinking reactions, synthesize insoluble resins, improve adhesion, and can be used as fiber treatment agents. It reacts with melamine formaldehyde (or urea formaldehyde) resin, epoxy resin, etc. to manufacture two component coatings. Adding it to high-end car paint can maintain the mirror gloss for a long time. It can also be used as an adhesive for synthetic textiles and as a medical polymer monomer
