摘要： PURPOSE:To obtain the subject dispersion with a low content of an organic solvent in a mixed solvent and useful as a coating. etc., by specifying the nitric ester group and the carboxyalkyl ether group substitution degrees and the neutralization degree of a neutralized substance of a carboxyalkyl nitrocellulose with a basic compound. CONSTITUTION:This aqueous resin dispersion is obtained by regulating a carboxyalkyl nitrocellulose having >=0.2 nitric ester group substitution degree and >=0.05 carboxyalkyl ether substitution degree based on one anhydroglucose group to 0.2-1.2, preferably 0.5-1.0 neutralization degree with a basic compound such as aqueous ammonia. The resultant neutralized substance is good in solubility in water and water resistance of the formed film and the aqueous resin dispersion prepared by dispersing the neutralized substance in a mixed solvent of water with a hydrophobic organic solvent has a low viscosity. Thereby, the amount of the organic solvent can remarkably be reduced and the film is good in stability of physical properties thereof with time.

摘要： PROBLEM TO BE SOLVED: To discover a method for recoverable acetic anhydride not contributed to a reaction after the reaction, capable of simplifying production equipment and to provide a method capable of simplifying production equipment and stabilizing quality in the method for producing acetylated nitrocellulose by reacting nitrocellulose with acetic anhydride. SOLUTION: This method performs an acetylation reaction of nitrocellulose in a state dispersed in a dispersion medium such as toluene while holding solid phase (fine fibers shape) and separates the resultant acetylated nitrocellulose from the reacted solution by filtration to be capable of recovering excess acetic anhydride not contributed to the reaction. By the method, a precipitation process formerly required in a solution reaction is to be useless and quality unstable factors caused by scattering of product particle size vanishes. Furthermore, acetylated nitrocellulose having excellent heat resistance and stability is provided by contriving a washing process for crude acetylated nitrocellulose after the reaction and adopting a washing with a detergent containing a stabilizer at a high temperature of 60-105 deg.C.
