登记用途：Uses: CIR ingredient: Acrylamide、Acrylamide is used as a reactive monomer and intermediate in the production of organic chemicals and in the synthesis of polyacrylamides. Acrylamide is also used as a flocculent for sewage and waste treatment、soil conditioning agents、ore processing、paper and textile industries、and in the manufacture of dyes、adhesives、and permanent press fabrics.、Used as a polymer or copolymer to produce sealants、fibers、paper sizing、molded parts、water coagulants、and textiles. In the United States、90% of acrylamide is used to produce polyacrylamide for water treatment (60%)、pulp and paper production (20%) and mineral processing (10%)、[ACGIH]、Pulp and Paper Processing [Category: Industry]、Textiles (Fiber & Fabric Manufacturing) [Category: Industry]、Working with Glues and Adhesives [Category: Other]、Mining [Category: Industry]、Sewer and Wastewater Treatment [Category: Industry]、Textiles (Printing、Dyeing、or Finishing) [Category: Industry]、For acrylamide (USEPA、OPP Pesticide Code: 600008) there are 0 labels match.、SRP: Not registered for current use in the U.S.、but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、It is used as a reactive monomer and intermediate in the production of organic chemicals. Acrylamide has a wide variety of uses as a polymer or copolymer in such applications as adhesives、water coagulant aids、grouting agent、and textiles.、Synthesis of dyes、... cross-linking agent、paper and textile sizes、soil-conditioning agents、flocculants、sewage and waste treatment、permanent-press fabrics.、Used in electrophoresis、molecular biology、genetic engineering.、For more Uses (Complete) data for ACRYLAMIDE (6 total)、please visit the HSDB record page.、Most acrylamide is used to synthesize polyacrylamides、which find many uses as water-soluble thickeners. Polyacrylamide was first used in a laboratory setting as polyacrylamide gel electrophoresis to separate charged molecules. Acrylamide has many other uses in molecular biology laboratories、including the use of linear polyacrylamide (LPA) as a carrier which aids in the precipitation of small amounts of DNA. Many laboratory supply companies sell LPA for this use. Some acrylamide is used in the manufacture of dyes and the manufacture of other monomers. Acrylamide also occurs in many cooked starchy foods、such as potato chips and French fries. (L1157)、Use Classification: Food Contaminant -> CONTAMINANT -> JECFA Functional Classes、Industry Uses: Monomers、Processing aids、specific to petroleum production、Household Products: Cosmetics product ingredient: Acrylamide、Source: Acrylamide is a colorless、odorless solid. It is a synthetic chemical used to make other compounds. Acrylamide may be a contaminant in polyacrylamide and other acrylamide-based compounds that are added to cosmetics to help blend the other ingredients.、Potential health impacts: People can be exposed to acrylamide through ingestion、through skin contact、or by inhalation of powder. Laboratory studies of human cells exposed to acrylamide have shown extensive DNA damage. Studies of animals fed acrylamide or exposed to it through the skin have found increased tumors as well as reproductive impacts. Studies of humans exposed to acrylamide、either through diet or occupational exposure、have documented nervous system impacts. Human studies have not shown sufficient evidence of increased risk of cancer in humans. However、based on animal studies、the International Agency for Research on Cancer (IARC) classifies acrylamide as a probable human carcinogen. California Proposition 65 lists acrylamide as a carcinogen and as a developmental and reproductive toxin.、Product count: 18、Information on 17 consumer products that contain Acrylamide in the following categories is provided:、• Auto Products、• Home Maintenance、• Inside the Home、Methods of Manufacturing: Sulfuric Acid Process. One mole of acrylonitrile is added to a solution of 1 mol sulfuric acid and 1 mol of water at 60 °C. The mixture is slowly heated to 80 °C、kept for an hour at this temperature、and then cooled to 40 °C. Ammonium sulfate precipitates on neutralization with ammonia and is filtered out. The acrylamide、which crystallizes on cooling the mother liquor to below 10 °C、is purified by recrystallization from benzene.、Catalytic Hydration Process. ... A 50 wt% solution of acrylonitrile in water is slurried with a catalyst such as Raney copper and kept at 120 °C for 2.5 hr. Conversion of acrylonitrile is greater than 50% and selectivity to the amide is nearly 100%. This process conveniently makes an aqueous solution of 30 to 50 wt% acrylamide because of the large amount of water required in the reaction.、Prepared from acrylonitrile by treatment with H2SO4 or HCl.、... Microorganisms、are used、for making acrylamide from arylonitrile using an enzymatic hydration process.、American Cyanamid has developed a proprietary catalytic direct hydration process for converting acrylonitrile to acrylamide involving reaction of water over solid surfaces of metals、metallic salts、or metallic oxides、eliminates the formation of by-products such as ammonium or sodium sulfate.、Impurities: Possible contaminants include sodium sulfate、acrylic acid、sulfuric acid、and water、depending on the mode of synthesis. The commercial product has been reported to contain residual levels of 1-100 mg、kg acrylonitrile.、Formulations、Preparations: Grade: Technical (approximately 97% pure)、The 50% aqueous acrylamide is the preferred form because it eliminates the handling of solids and because its cost is lower.、Liquid and powder、ultrapure grades、99% pure、liquid is 40% solution (wt、vol) in specially deionized water.、Consumption Patterns: 40% FOR POLYACRYLAMIDES USED IN THE WATER TREATMENT INDUSTRY、20% FOR POLYACRYLAMIDES USED。
