Read： 1155 Time：28months ago Source：

acrylamide (or acrylamide) is an organic compound, a white odorless solid, easily soluble in water and several organic solvents. It is colorless and odorless crystal. It's highly toxic. Soluble in water, ethanol, acetone, ether and trichloroethane, slightly soluble in toluene, insoluble in benzene. It is stable at room temperature, but it polymerizes suddenly when molten. Melting point 84~86 ℃. Boiling point 87 ℃(0. 26kPa), 125 ℃(3. 3kPa). Relative density 1. 122. Refractive index 1.460 (calculated value). It is the most important product in acrylamide and methacrylamide products, and is the raw material for the production of polyacrylamide.

Six functions and uses

of acrylamide 1. Used in the manufacture of water-soluble polymer-polyacrylamide, which can be used as a chemical grouting agent for water plugging and sand fixation in tunnels, oil wells, mines and dams; beneficiation, coal washing, water treatment and drilling mud flocs and underwater and underground building preservatives, etc

2. Used as soil conditioner, fiber modifier, binder, photosensitive resin crosslinking agent, paper reinforcing agent, etc.

3. Used as a crosslinking agent for vinyl polymers and made lipophilic polymers increase adhesion, resin softening point and solvent resistance.

4. Used for determination of acid relative molecular mass

5. Monomer used as polyacrylamide

6. Used to make polyacrylamide gel for electrophoresis determination of protein molecular weight, etc. Flocculant, soil stabilizer, enhance paper strength, improve fiber quality, binder.
