登记用途:Uses: Acrylic acid is used in the manufacture of plastics、in latex applications、in floor polish、in polymer solutions for coatings applications、emulsion polymers、paint formulations、leather finishings、and paper coatings. Acrylic acid is also used as a chemical intermediate.、Acrylic acid is used to manufacture acrylic resins and acrylates for leather coatings、paints、and adhesives. [ACGIH]、Used in the manufacture of plastics、molding powder for signs、construction units、decorative emblems and insignias、polymer solutions for coatings applications、paints formulations、and paper coatings、... also used in medicine and dentistry for dental plates、artificial teeth、and orthopedic cement.、Most acrylic acid is consumed in the form of the polymer. The dominant share of acrylic acid is converted to esters. Today growth is in the demand for superabsorbents (SAPs) for use in diapers and hygienic products. Acrylic acid accounts for 80-85% of raw materials used in the manufacture of SAPs.、Monomer for polyacrylic and polymethacrylic acids and other acrylic polymer.、Chemical intermediate for ethyl acrylate、n-butyl acrylate、methyl acrylate、2-ethylhexyl acrylate、for other specialty acrylates、eg、hydroxyethyl、monomer for polyacrylic acid and salts、thickeners、comonomer with acrylamide for polymers used as flocculants、with ethylene for ion exchange resin polymers、with methyl ester for polymers、for other copolymers、with itatonic acid、For more Uses (Complete) data for Acrylic acid (14 total)、please visit the HSDB record page.、Industry Uses: Plasticizer、Cleaning agent、Filler、Intermediate、Anti-scaling agent、Pigment、Polymerization promoter、Dispersing agent、Binder、Other、Wrinkle resisting agent、Monomers、Chemical reaction regulator、Consumer Uses: Monomers、Not Known or Reasonably Ascertainable、Adhesion、cohesion promoter、Household Products: Cosmetics product ingredient: Acrylic acid、Reason for Listing:、- Identified as Toxic Air Contaminants under sections 93000 and 93001 of title 17 of the California Code of Regulations、- The United States Environmental Protection Agency’s Integrated Risk Information System developed a reference dose or reference concentration based on this substance's neurotoxicity、- Identified with non-cancer endpoints and listed with an inhalation or oral Reference Exposure Level by the California Office of Environmental Health Hazard Assessment under Health and Safety Code section 44360(b)(2)、Potential Health Impacts: Dermatotoxicity、Nephrotoxicity and other Toxicity to the Urinary System、and Respiratory Toxicity、Product count: 10、Information on 29 consumer products that contain Acrylic acid in the following categories is provided:、• Auto Products、• Commercial、Institutional、• Home Maintenance、• Inside the Home、• Personal Care、Methods of Manufacturing: (1) Condensation of ethylene oxide with hydrocyanic acid followed by reaction with sulfuric acid at 320 °F、(2) acetylene、carbon monoxide、and water、with nickel catalyst、(3) propylene is vapor oxidized to acrolein、which is oxidized to acrylic acid at 300 °C with molybdenum-vanadium catalyst、(4) hydrolysis of acrylonitrile.、CHEMICAL PROFILE: Acrylic acid. Industrial production is by gas-phase catalytic oxidation of propylene. Roughly、three-quarters of production are converted directly into acrylate esters and the rest is purified into glacial acrylic acid.、CHEMICAL PROFILE: Acrylic acid. Technology: Most production is based on the gas phase catalytic oxidation of propylene via acrolein. The reaction can be carried out in single or two-step processes、but the latter is favoured because of higher yields. The oxidation of propylene produces acrolein、acrylic acid、acetaldehyde and carbon oxides. Acrylic acid from the primary oxidation can be recovered while the acrolein is fed to a second step to make acrylic acid. Purification can be carried out by azeotropic distillation.、Impurities: ... Typical commercial glacial acrylic acid contains 98.0% by wt acrylic acid、max of 0.5% by wt water and 0.045-0.055 mg、kg (ppm) of the inhibitor hydroquinone monomethyl ether.、< 0.05% w、w water、w propionic acid、< 0.2% w、w acetic acid、< 0.5% w、w dimers of acrylic acid、(additives) < 0.02% hydroquinone monomethylether、Commercial acrylic acid also contains a small amount of polymerization inhibitors、usually hydroquinone monomethyl ether (methoxyphenol). This is a known skin sensitizer in guinea-pigs ... Other inhibitors used with acrylic acid have also been reported to have skin-sensitizing properties、namely phenothiazine ... and diphenyl-p-phenylenediamine ... However、it is unclear whether the small amount of one of these inhibitors present (0.02-0.1%) could contribute to the skin-sensitizing properties of commercial acrylic acid.、Formulations、Preparations: Acrylic acid is commercially available in USA in 2 grades: (a) technical grade for esterification and polymerization、and (b) glacial grade for production of water-sol resins. Typical commercial glacial acrylic acid contains 98.0% by wt acrylic acid、kg (ppm) of inhibitor ...、Grade: Technical (esterification and polymerization grades)、glacial (97%).、Acrylic acid and esters are stabilized with minimum amounts of inhibitors consistent with stability and safety. The acrylic monomers must be stable and there should be no polymer formation for prolonged periods with normal storage and shipping. The monomethyl ether of hydroquinone (MEHQ) is frequently used as inhibitor and low inhibitor grades of the acrylate monomers are available for bulk handling. MEHQ at 10-15 ppm is generally adequate for the esters、but a higher concentration (200 ppm) is needed for acrylic acid.、Consumption Patterns: Chemical intermediate for ethyl acrylate、40%、chemical intermediate for n-butyl acrylate、34%、chemical intermediate for methyl acrylate。
