Acrylic acid lignocellulosic

Vinyl monomers that can be grafted to cellulose to achieve adhesive properties are acrylic acid, acrylonitrile, methyl methacrylate, and many others. Graft copolymers of cellulose derivatives have also found use as adhesives. For example, vinylacetate-grafted hydroxyethylcellulose can be used as an adhesive for packaging and tile ( ). Grafting of vinyl monomers onto lignocellulosic materials can convert them into suitable adhesive materials (0). 

Acrylic acid-modified Ficus carica lignocellulosic fiber was used as adsorbent. And the removal of Cr(VI) was evaluated in the presence of various metal ions aqueous solutions [87]. The F. carica fibers were washed, dried at 50°C for 24 h, and soxhlet extracted with acetone for 12 h in order to remove waxes and lignin. Then it was dried at 50°C for 5h and then cut into pieces of 1.0-1.5mm-size. The F. carica fibers were immersed in 100 ml of double distilled water for 24 h in order to activate the reactive sites. A known amount of ceric ammonium nitrate, concentrated nitric acid, and acrylic acid was added to the flask containing the fiber. The mixture was heated to constant temperature for a definite time. The modified F carica fibers were washed with ethanol and dried at 50°C to a constant weight. The maximum adsorption capacity of Cr(VI) onto adsorbent was found to be 28.90 mg g". ...

Levulinic acid is formed by the treatment of six-carbon sugar carbohydrates from starch or lignocellulosics with acids, or by add treatment plus a reductive step of five-carbon sugars derived from hemicellulose. Levulinic add can serve as a building block for the synthesis of many derivatives of interest may be the selective oxidation to succinic and acrylic add. [i-Acetylacrylic add could be used in the production of new acrylate polymers.
