  Methods for making metal particle-chitin composite materials are described. The methods can comprise contacting an ionic liquid with chitin, thereby forming a mixture; contacting the mixture with a non-solvent, thereby forming a chitin substrate in the non-solvent; collecting the chitin substrate from the non-solvent; deacetylating the collected chitin substrate, thereby forming a deacetylated chitin substrate; contacting the deacetylated chitin substrate with a metal salt, thereby forming an impregnated precursor composite material; and contacting the impregnated precursor composite material with a reducing agent, thereby reducing the metal salt to form a plurality of metal particles dispersed on the chitin substrate and forming the metal particle-chitin composite material.

  本文介绍了制造金属颗粒-甲壳素复合材料的方法。这些方法可包括：将离子液体与甲壳素接触，从而形成混合物；将混合物与非溶剂接触，从而在非溶剂中形成甲壳素基质；从非溶剂中收集甲壳素基质；使收集的甲壳素基质脱乙酰基，从而形成脱乙酰基甲壳素基质；将脱乙酰甲壳素基质与金属盐接触，从而形成浸渍前体复合材料；以及 将浸渍前体复合材料与还原剂接触，从而还原金属盐，形成分散在甲壳素基质上的多个金属颗粒，并形成金属颗粒-甲壳素复合材料。

  Methods for separating chitin from a chitinous biomass are described, the methods comprising contacting the chitinous biomass with an ionic liquid to form a mixture comprising chitin; contacting the mixture with an aqueous solution of a kosmotropic salt, thereby coagulating the chitin and forming an biphasic system comprising an ionic liquid-chitin phase and an aqueous kosmotropic salt phase; separating the ionic liquid-chitin phase from the aqueous kosmotropic salt phase; and collecting the chitin from the separated ionic liquid-chitin phase, thereby forming a recycled ionic liquid.

  描述了从甲壳质生物体中分离甲壳素的方法，该方法包括将甲壳质生物体与离子液体接触，形成包含甲壳素的混合物；将该混合物与高渗盐水溶液接触，从而使甲壳素凝固，形成包含离子液体-甲壳素相和高渗盐水相的双相体系；将离子液体-甲壳素相与水性各向同性盐相分离；并从分离的离子液体-甲壳素相中收集甲壳素，从而形成循环离子液体。

  Disclosed is a process for forming films, fibers, and beads comprising a chitinous mass, for example, chitin, chitosan obtained from one or more biomasses. The disclosed process can be used to prepare films, fibers, and beads comprising only polymers, i.e., chitin, obtained from a suitable biomass, or the films, fibers, and beads can comprise a mixture of polymers obtained from a suitable biomass and a naturally occurring and/or synthetic polymer. Disclosed herein are the films, fibers, and beads obtained from the disclosed process. This Abstract is presented solely to aid in searching the subject matter disclosed herein and is not intended to define, limit, or otherwise provide the full scope of the disclosed subject matter.

  The invention relates to the dyeing of human keratin fibres, especially the hair, using anionic direct dyes bearing a particular ammonium or phosphonium counterion of formula (Ia) and/or optical brighteners of formula (Ib) Col (−) m [X + ] n (Ia) Azu (−) m [X + ] n (Ib) in which formulae (Ia) and (Ib): Azu/Col (−) m, R 1 , R 2 , R 3 , R 4 , m and n are as defined in the description. The invention relates to a dye composition comprising an anionic compound of formula (Ia) and/or (Ib), and to a process for dyeing keratin fibres such as the hair, using the said composition. Similarly, the invention relates to novel anionic compounds of formula (Ia) or (Ib) and to the uses thereof for dyeing keratin fibres. This composition makes it possible to obtain chromatic, powerful and particularly fast coloration on keratin fibres and particularly lightening coloration via an optical effect on dark hair.
