Estimating environmentally important properties of chemicals from the chemical structure
Rapportens titel och undertitel/Title and subtitle of the report Estimating environmentally important properties of chemicals from the chemical structure Sammanfattning/Summary The development of models to predict important environmental properties is easily recognised in the light of the great number of existing chemicals that still need to be characterised. To meet the needs for testing new c...
متن کاملThe use of lignin derivatives to improve selected paper properties
Wood consists mainly of three types of polymers; cellulose, hemi cellulose and lignin. Lignin is formed in nature through enzymatic initiated oxidative coupling of three different kinds of phenyl propane units. These form by various carbon-carbon and carbon-oxygen bonds, an amorphous three-dimensional polymer. As chemical pulp is produced, lignin is degraded and dissolved into pulping liquors. ...
متن کاملCatalytic transformation of carbohydrates and lignin in ionic liquids
Ionic liquids with anions of strong hydrogen-bond basicity have been broadly reported in the literature as effective solvents for the dissolution of the components of lignocellulosic biomass. The key attributes of various ionic liquids are reviewed with a focus on their structural and functional properties related to biomass dissolution capacity. A number of the most studied ionic liquids with ...
متن کاملWood Based Lignin Reactions Important to the Biorefinery and Pulp and Paper Industries
The cleavage of lignin bonds in a wood matrix is an important step in the processes employed in both the biorefinery and pulp and paper industries. β-O-4 ether linkages are susceptible to both acidic and alkaline hydrolysis. The cleavage of α-ether linkages rapidly occurs under mildly acidic reaction conditions, resulting in lower molecular weight lignin fragments. Acidic reactions are typicall...
متن کاملEnvironmentally safe corrosion inhibition of Pb in aqueous solutions
The corrosion and corrosion inhibition of lead in aqueous solutions with different pHs (2, 7 and 12) were investigated. The corrosion rate was alculated in the absence and presence of the corrosion inhibitor using polarization and impedance techniques. Amino acids have been used as nvironmentally safe corrosion inhibitors. The inhibition efficiency of the different amino acids at a concentratio...
