    摘要： Instilling an acidic catalyst to a reaction mixture can be beneficial during the acylation of cellulose. Methods described herein can comprise preparing a reaction mixture comprising an acylating agent and cellulose, instilling a catalyst comprising an acid to the reaction mixture at an overall catalyst loading level of about 1% or less by weight of the cellulose, and reacting the cellulose with the acylating agent in the presence of the catalyst, thereby forming an acylated cellulose.

    摘要翻译： 在纤维素酰化期间向反应混合物中滴注酸性催化剂可能是有益的。 本文所述的方法可以包括制备包含酰化剂和纤维素的反应混合物，以占纤维素重量的约1％或更小的总催化剂负载水平向反应混合物灌注包含酸的催化剂，并且使纤维素与 酰化剂在催化剂存在下反应，从而形成酰化纤维素。

    摘要： Instilling an acidic catalyst to a reaction mixture can be beneficial during the acylation of cellulose. Methods described herein can comprise preparing a reaction mixture comprising an acylating agent and cellulose, instilling a catalyst comprising an acid to the reaction mixture at an overall catalyst loading level of about 10% to about 20% by weight of the cellulose, and reacting the cellulose with the acylating agent in the presence of the catalyst, thereby forming an acylated cellulose.

    摘要： High-throughput production methods for manufacturing porous masses suitable for use in conjunction with smoking devices may include continuously combining a matrix material and a paper wrapper to form a desired cross-sectional shape where the matrix material is confined by the paper wrapper, the matrix material comprising a binder particle and an active particle; heating at least a portion of the matrix material so as to bind the matrix material at a plurality of contact points, thereby forming a porous mass length, wherein heating involves irradiating with microwave radiation at least a portion of the matrix material; cooling the porous mass length; and cutting the porous mass length radially thereby producing a porous mass.
