Preparation and characterization of some ionic liquids and their use in the dimerization reaction of 2-methylpropene

This study concentrates on the preparation and characterization of some ionic liquids and their use in dimerization reaction of 2-methylpropene. Ionic liquids consist of cations and anions, and are commonly understood as green solvents. By definition

Selective hemicellulose hydrolysis of Scots pine sawdust

Autor: Rusanen, A. (Annu), Lappalainen, K. (Katja), Kärkkäinen, J. (Johanna), Tuuttila, T. (Tero), Mikola, M. (Marja), Lassi, U. (Ulla)

The depletion of fossil resources is driving forward the search for new and alternative renewable feedstocks in the production of renewable chemicals, which could replace the petroleum-based ones. One such feedstock is pine (Pinus sylvestris) sawdust

Microwave-assisted conversion of novel biomass materials into levulinic acid

Autor: Lappalainen, K. (Katja), Vogeler, N. (Nils), Kärkkäinen, J. (Johanna), Dong, Y. (Yue), Niemelä, M. (Matti), Rusanen, A. (Annu), Ruotsalainen, A. L. (Anna Liisa), Wäli, P. (Piippa), Markkola, A. (Annamari), Lassi, U. (Ulla)

Levulinic acid is considered one of the most important platform chemicals. It is currently produced mainly from lignocellulosic biomasses. However, there are also other abundant biomass materials, which could be used as raw materials for levulinic ac

Catalytic conversion of sawdust-based sugars into 5-hydroxymethylfurfural and furfural

Autor: Rusanen, A. (Annu)

Sawdust is an abundant but poorly utilized lignocellulosic side stream. It is mainly burned as energy despite the fact that it could be utilized in the production of biomass-based chemicals. Sawdust is composed of cellulose, hemicellulose, and lignin

Modification of native and waste starch by depolymerization and cationization:utilization of modified starch in binding of heavy metal ions from an aqueous solution

Autor: Lappalainen, K. (Katja)

Starch is one of the most abundant polysaccharides found in nature and is widely utilized in various fields of industry. Due to the complex structure of native starch it is insoluble in most organic solvents and needs modification prior utilization.
