Liquid lignosulfonate

New process extracts lignin from pulp mill black liquor

LignoBoost works in conjunction with evaporation. It all starts with lignin being precipitated from the black liquor by lowering the pH with CO2. The precipitate is then dewatered using a filter press. LignoBoost then overcomes conventional filtering and sodium separation problems by redissolving the lignin in spent wash water and acid. The resulting slurry is […]

Straw lignin glycerol structure changes during cooking

Straw lignin glycerol structure changes during cooking After glycerol mainly wheat straw lignin isolated after cooking for chemical structure analysis, and the Central Plains and some straw lignin were compared. Shows that two kinds of lignin are made from guaiacyl, lilac wood-based and wood-based hydroxyphenyl three basic structural units, which guaiacyl unit as the main […]

Effect of lignosulfonate to Urea working inside the soil

Effect of lignosulfonate to Urea working inside the soil A field experiment to study the soil fertilized lignin conversion to urea and wheat biomass, nitrogen nutrition. The results showed that lignin can regulate the release of inorganic nitrogen, showing the application of green winter wheat soil inorganic nitrogen content of lignin and lower jointing higher […]

Lignin graft copolymerization of acrylic monomer -2

Lignin graft copolymerization of acrylic monomer -2 Chemistry – induced hydrolysis Until recently only been reported , mostly using a phenolic peroxidase (phenoloxidase), mainly laccase in the presence of peroxidase , lignin itself radical polymerization mechanism may be lignin hydrolysis radicals and long chain radicals with acrylic acid ( the formula ) , formed with […]

Lignin graft copolymerization of acrylic monomer -1

Lignin graft copolymerization of acrylic monomer -1 Lignin monomer vinyl radical graft copolymerization , the most studied is the reaction of lignin and acrylamide because these monomers acrylamide maximum activity , the use of a cerium salt initiator , H2O22Fe (Ⅱ ) , potassium permanganate , persulfate , and γ2 rays. 0.001mol/LNaOH dissolved lignin solution […]

Lignin and styrene graft copolymer

Lignin and styrene graft copolymer Benzene extraction of lignin using the grafting reaction with styrene , the test procedure is as follows : the pure styrene ( Sample A) was added to the conical flask, and passed N2 10min, lignin , CaCl2 , and dimethylsulfoxide (DMSO ) ( sample B) was added to another Erlenmeyer […]
