Sucrose carbohydrate based resources

Within the framework of a research project together with Dutch based paint producer SigmaKalon, the development of alkyd resins with low intrinsic viscosity was aimed for. In order to achieve this, we explored the potential of two types of renewable, carbohydrate derived resources as the polyhydric alcohol part of alkyd resins, i.e. sucrose and inulin. " These carbohydrate based resources were chosen because of various reasons ... 

Carbohydrate-based surfactants are the final result of a product concept that is based on the greatest possible use of renewable resources. While the derivatisation of fats and oils to produce a variety of different surfactants for a broad range of applications has a long tradition and is well established [1, 2], the production of surfactants based on fats and oils and carbohydrates on a bigger industrial scale is relatively new. Today the most important carbohydrate-based surfactants are alkyl polyglycosides, sorbitan esters and sucrose esters [3]. 

The development of surfactants based on carbohydrates and oils is the result of a product concept based on the exclusive use of renewable resources. In industry, saccharose (sucrose), glucose and sorbitol, which are available in large amounts and at attractive prices, are used as the preferred carbohydrate raw materials. 

Based on the universally available renewable resource sucrose, a few technically interesting substances maintaining the carbohydrate structure can be produced. Thereby, the bound glucose and fructose units of the sucrose molecule are either split or rearranged (Figure 9.3.7). 

The objective of our woik is to provide mechanically strong caibon support bodies of a narrow size distribution from renewable biomass resources. A second objective is to provide supported base metal catalysts without using Itydrogen gas as a reducing agent We start from hydrophihc bodies of carbohydrates, such as Micro Crystalline Cellulose (MCC) spheres or partially Carbonized Sucrose (CS) spheres prepared by hydrothermal treatment of an aqueous sucrose (common table sugar) solution.
