| titleOfInvention | Process for obtaining nitrocellulose, wood cellulose nitration process for obtaining nitrocellulose and nitrocellulose obtained by such process |
| abstract | PATENT OF INVENTION ON THE PROCESS FOR OBTAINING NITROCELLULOSIS, WOOD CELLULOSE NITRATION PROCESS FOR OBTAINING NITROCELLULOSIS AND NITROCELLULOSIS OBTAINED BY SUCH PROCESS. The present invention deals with the process of obtaining nitrocellulose from short cellulose fibers. Nitrocellulose is a product used as a resin in paint formulation, being responsible for the transfer and formation properties of the formed film. It is also widely used in automotive refinish, wood sealers and finishes, gravure and flexo printing inks, nail polishes and leather finishes, to name a few applications. The process according to the invention employs short fibers having an average length of 0.85 mm or less from coils or subdivided sheets of alpha cellulose whose coils or sheets have a density ranging from about 0.7 to about 1, 0 g / cm3 and viscosity above 300 cP, which react with water, sulfuric acid and nitric acid (sulfonitric mixture or MSN) in a mass ratio of sulfonitrile / cellulose mixture ranging from about 1: 7 to about 1: 45 |
