摘要： Dried nanocrystalline cellulose (NCC), in particular films of NCC, of controlled water dispersibility and a method to control the dispersibility of dried NCC by controlling electrolyte solution ionic strength and ion valency is described. Neutral M-NCC suspensions containing monovalent counterions (e.g., M=Na+, K+, NH4+, Et4N+) produced by neutralization of acid-form NCC (H-NCC) with the appropriate hydroxide, are readily dispersible in water when fully dried; this is in contrast to H-NCC. The dispersion of dried M-NCC in aqueous media is effectively prevented by a combination of (1) increased electrolyte concentration and ionic strength, and (2) higher valency of the cation component of the dissolved salt. Additionally, pre-treatment of dried M-NCC films with an electrolyte solution having a polyvalent cation, for example a divalent or trivalent cation is sufficient to prevent the subsequent dispersion of the M-NCC film in pure water.
摘要翻译：描述了干燥的纳米晶纤维素（NCC），特别是NCC的膜的受控水分散性，以及通过控制电解质溶液的离子强度和离子价态来控制干燥的NCC的分散性的方法。通过用合适的氢氧化物中和酸形式NCC（H-NCC）产生的含有一价抗衡离子（例如M = Na +，K +，NH 4 +，Et 4 N +）的中性M-NCC悬浮液在完全干燥时容易分散在水中; 这与H-NCC相反。干燥的M-NCC在水性介质中的分散体通过（1）增加的电解质浓度和离子强度的组合和（2）溶解盐的阳离子组分的更高的价态被有效地预防。另外，用具有多价阳离子（例如二价或三价阳离子）的电解质溶液预处理干燥的M-NCC膜足以防止M-NCC膜随后在纯水中分散。

摘要： Provided is a method of producing hydroxyalkylcellulose microparticles, the method including generating a pulse shock wave, and supplying a hydroxyalkylcellulose aqueous solution to the pulse shock wave generation region, thereby crushing and drying the hydroxyalkylcellulose aqueous solution. According to the production method, hydroxyalkylcellulose microparticles having a volume-average particle size of at least 0.1 μm but less than 15 μm are obtained. By mixing the hydroxyalkylcellulose microparticles with a principal agent and subjecting the resulting mixture to a tablet compression, a solid preparation having excellent tensile strength and disintegration properties can be obtained.
