Saving Humanity from Global Warming. New Ecologically Balanced Catalytic Method for Processing of Renewable Plant Raw Materials: Quantitative 1H and 13C NMR Spectroscopy.

The most high-tonnage product of processing vegetable raw materials is cellulose. Currently, sulfate cooking is the most common method of pulp production. However, this method is extremely toxic and has a huge negative impact on the environment. An alternative to this is a catalytic process. Catalysts reduce harmful emissions into the atmosphere by up to 80%. During cellulose cooking, the most important chemical reaction is the destruction (hydrolysis) of lignin macromolecules. A comparative study of the macromolecular structure of pine dioxane lignin and lignins obtained by various methods of alkaline pine wood delignification such as soda process, soda with elemental sulphur and soda with 1,4–dihydro–9,10–dihydroxyanthracene (DDA) disodium salt as a delignification catalyst and with a novel delignification catalyst (DC) was carried out using quantitative 1H and 13C NMR spectroscopy.
