The invention concerns a process for the manufacture of an acylated polymer composition comprising amylose and/or amylopectin, comprising a pre-treatment step in the presence of an acid and a hydroxycarboxylic acid, subsequent acylation and, preferably, a post-treatment step with an acid. The products obtained are useful as additives in inks, varnishes, lacquers, coatings, thickeners, adhesives or binders.

This invention relates to the use of destructurized starch as a thickening agent in cosmetic, dermatological and pharmaceutical compositions, paints, phytosanitary products and detergents.

Improved thermally inhibited starch is disclosed and methods of making such starch are disclosed. In some embodiments a thermally inhibited starch has improved whiteness and flavor. In some embodiments a method for making a thermally inhibited starch includes providing adding a buffer and an acid to a starch to obtain a pH adjusted starch having an acidic pH and thermally inhibiting the pH adjusted starch. The technology further pertains to methods of making the thermally inhibited starch in batch, continuous, continuous-like process or combinations thereof.

Provided herein are processes for making an anode containing an anode material, a protective material, and a current collector. The anode material is a mixture containing an active material, at least one electronically conductive agent and at least one binder. The active material may be an alloy of silicon and lithium or an alloy of silicon oxide and lithium. Processes also include use of the anodes in the fabrication of a battery.

SAE-CD compositions are provided, along with methods of making and using the same. The SAE-CD compositions comprise a sulfoalkyl ether cyclodextrin having an absorption of less than 0.5 A.U. due to a drug-degrading agent, as determined by UV/vis spectrophotometry at a wavelength of 245 nm to 270 nm for an aqueous solution containing 300 mg of the SAE-CD composition per mL of solution in a cell having a 1 cm path length.

Methods for recovering gold from gold-bearing materials are provided. The methods rely upon on the self-assembly of KAuBr.sub.4 and -cyclodextrin (-CD) in aqueous solution to form a co-precipitate, a 1:2 complex, KAuBr.sub.4(-CD).sub.2 (Br), either alone or in an extended {[K(OH.sub.2).sub.6][AuBr.sub.4](-CD).sub.2}.sub.n chain superstructure (FIG. 1). The co-precipitation of Br is selective for gold, even in the presence of other metals, including other square-planar noble metals. The method enables one to isolate gold from gold-bearing materials from diverse sources, as further described.

A method of modifying a polymer having hydroxyl groups, selected from the group of polysaccharides and lignin, to give a modified polymer comprising the step of contacting said polymer with at least one organic phosphonate salt in order to chemically modify the polymer, said organic phosphonate salt being in a liquid phase. The method of polymer modification provides novel polymers. Modified polymers obtained from a polymer having been treated with at least one organic phosphonate salt are also disclosed. The modified polymers can be used as such or separated and optionally recovered from the solution, optionally being formed into particular materials or shapes.
