    Abstract: 一种制备改性纤维素的方法及装置，包括反应釜，反应釜内设有用于反应的固液空间，和用于容纳从固液空间内溢出的气体的气相空间，在反应釜外设有一外循环系统，外循环系统的入口端与反应釜内的气相空间连通设置，外循环系统的出口端深入到反应釜内设置。本申请用于纤维素制备羟丙基甲基纤维素、羟乙基甲基纤维素等物质，在纤维素醚化反应进行时，在固液空间内的液体受热气化，先进入到气相空间，然后再通过外循环系统循环进入到反应釜内，使得可以降低釜内压力，保证整体的安全性能，降低反应釜的耐压性能和密封性能，同时液体持续经过外循环系统回到反应釜内，使反应釜内反应液始终处于过剩状态，反应速度快，生产效率高。

    Abstract: A process includes: (a) providing an initial cellulose ether powder containing 0.5 to 10 weight-percent water based on total cellulose ether powder weight; (b) heating the initial cellulose ether powder to a temperature in a range of 30 to 130 degrees Celsius; (c) before, during and/or after heating in step (b), adding solid base to the cellulose ether powder and mixing with the initial cellulose ether powder to form a cellulose ether/base mixture; (d) adding volatile acid to the cellulose ether/base mixture and mixing; and (e) allowing the volatile acid to hydrolyze the initial cellulose ether to form a final cellulose ether having a lower viscosity than the initial cellulose ether.

    Abstract: This invention relates to absorbent materials useful in the manufacture of absorbent articles, in particular dressings for the advanced wound care market. The absorbent materials of the present invention are sulfonated polysaccharides, particularly water-insoluble cellulose alkyl sulfonates in which the cellulose is substituted by one type of alkyl sulfonate group. The invention also provides a process for the manufacture of such materials. The preferred cellulose alkyl sulfonate described herein is cellulose ethyl sulfonate. Reinforcing fibers and/or antimicrobial agents are optionally applied to the cellulose alkyl sulfonate.

    Abstract: Inhibitors against the absorption of sodium ion containing as the active ingredient metal salts (excluding sodium salt) of cellulose derivatives of the general formula (I): R-O-A, which effectively inhibit excess common salt existing in the body from being absorbed into the body system and excrete the common salt outside the body actively and safely; preventive or therapeutic agents for disease attributed to the existence of excess common salt or those necessitating restriction on the ingestion of common salt, containing the above metal salts as the active ingredient; and foods containing the same. In said formula R is a cellulose residue; and A is a functional group having an ability to exchange cations.

    Abstract: Polysaccharide derivatives in which some or all of the hydroxyl groups have been substituted by hydrophobic substituent(s) (A) having as the partial structure a C8-43 hydrocarbon group, and ionic hydrophilic substituent(s) (B) having as the partial structure at least one group selected from the group consisting of sulfonate, carboxyl, phosphate and sulfate groups and salts thereof, which have an average degree of substitution per constituting monosaccharide residue by the substituent (A), determined by Zeisel's method or the diazomethane method, of at least 0.0001 but less than 0.001 and an average degree of substitution per constituting monosaccharide residue by the substituent (B), determined by the colloidal titration method, of from 0.01 to 2.0. These derivatives are useful as chemical admixtures for hydraulic materials and give hydraulic compositions excellent in dispersibility and stability.
