METHOD TO PRODUCE TITANIUM-CONTAINING CELLULOSE MATERIALS Russian patent published in 2013 - IPC C08B1/00 

Abstract RU 2493169 C1

FIELD: biotechnologies.

SUBSTANCE: method includes destruction of lignocellulose materials as a result of their exposure to titanium-containing solutions of Lewis acids with application of an organic dissolvent during mixing, washing and drying of a target product. The lignocellulose material is represented by different types of lignocellulose raw materials produced from the following: wood semi-finished products in process of its treatment at pulp and paper plants, grass raw materials, and also from secondary (waste paper) raw materials, any other source of cellulose. Destruction is carried out at 20-70°C during mixing for 2-300 min. in the range of concentrations of the Lewis acid solution as 16-204 mmole/dm3 in the organic dissolvent.

EFFECT: invention makes it possible to product titanium-containing cellulose materials with high reactivity from lignocellulose materials.
