アクリルアミド

アクリルアミドは、室温で白色の結晶性無臭固体であり、融点は84.5 °Cで、水への溶解度は中程度である。これは不飽和アミドに分類される有機化学物質であり、主に反応性モノマーおよび化学中間体として用いられる。その主要な工業的用途は、ポリアクリルアミドポリマーの製造であり、これらのポリマーは水処理、石油回収効率向上、製紙、鉱山処理などに使用される。アクリルアミドはまた、グラウト材、土壌改良剤、および塗料・接着剤向けの特定の特殊化学品の合成にも利用される。

1. It can be used as a monomer of polyacrylamide. Its polymer or copolymer is used as chemical grouting materials, soil conditioners, flocculants, adhesives and coatings. 2. Polyacrylamide, when used as a kind of additive, can improve the oil recycling efficiency. When used as flocculants, it can be used for sewage treatment. It can also be used as a paper strength agent. 3. Acrylamide is the most important products in acrylamide and methacrylamide-based products. Since its application in industry in 1954, the demand gradually increase. It is mainly used for the preparation of water soluble polymers which can be used as additives to improve oil recovery; as a flocculant, thickening agents, and paper additives. A small amount of acrylamide is introduce the hydrophilic center into the lipophilic polymer to improve the viscosity, increase the softening point and improve anti-solvents ability of resin, and can aso introduce a center for the coloring property of dye. Acrylamide is also often used as a component of the photopolymer. For the vinyl polymer, its crosslinking reaction can take advantage of this kind of reactive amide groups. Acrylamide can co-polymerizze with certain monomers such as vinyl acetate, styrene, vinyl chloride, vinylidene chloride, and acrylonitrile to obtain a polymer with a variety of applications. The main application areas: (1) used for the oilfield; the materials can be used in oilfield injection of wells for adjustment of the injection profile. Mix this product with initiator, and deaerator and inject into the high permeability layer part of water wells. This will lead the formation of high-viscosity polymer unearth of the stratum. This can plug the large pore, increase the swept volume of oil, and enhance the oil recovery. In addition, the product polymer or copolymer can be used for tertiary oil recovery, fracturing, water shutoff, drilling mixing process and chemical grouting. (2) It can be used as flocculants. Its partially hydrolyzed product and its graft copolymer of methyl cellulose can be used in wastewater treatment and sewage treatment. (3) Soil conditioner; using the hydrolyzed product as soil amendments can aggregate soil and can improve air circulation, water permeability and water retention. (4) Modification of fiber and resin processing; using acrylamide for carbamylation or graft polymerization can improve the resin arrangement of a variety of fiber containing synthetic fiber, as well as for warp and printing paste in order to improve the basic physical properties of fabrics as well as preventing wrinkle, shrink and keeping a good hand feeling. (5) It can be used as paper enhancer; copolymer of acrylamide and acrylic acid or partial hydrolysis products of polyacrylamide can be used as paper strength reinforcing agent for either replacing or combining with starch, and water-soluble amino resin. (6) it can be used as an adhesive agent including glass fiber adhesive agent with the combination of phenolic resin and polyacrylamide solution, as well as pressure sensitive adhesive combined with synthetic rubber.4. It is the raw material for producing polyacrylamide and related products. 5. It can be used as the monomer of polyacrylamide. Its polymer or copolymer can be used as chemical grouting materials, soil conditioners, flocculants, adhesives and coatings. Polyacrylamide, as an additive, can improve oil recovery. As a kind of flocculants, it can be used for waste water treatment as well as paper strength enhancer can. It is the raw material for producing polyacrylamide and related products. It can also used for determining the relative molecular weight of acid.
