This invention provide processes for producing carboxylic acid product, along with useful salts. The carboxylic acid product that is produced according to this invention is preferably a C-Ccarboxylic acid. Among the salts produced in the process of the invention are ammonium salts.

Production of carboxylic acid and salt co-products

This invention is directed to methods of obtaining a high quantity of desired acid salt in a form that is relatively easy to recover. Particularly desired as a recovery product is an organic acid. A salt form of the desired organic acid is formed that is relatively high in concentration and that is relatively soluble in an aqueous medium. The method includes a step of fermenting a fermentable carbon source in the fermentation medium in the presence of a magnesium compound containing oxygen.

Fermentation method using a magnesium compound containing oxygen

Disclosed are polymer-based coatings and materials comprising (i) a polymeric composition including a polymer having side chains along a backbone forming the polymer, at least two of the side chains being substituted with a heteroatom selected from oxygen, nitrogen, sulfur, and phosphorus and combinations thereof; and (ii) a plurality of metal species distributed within the polymer. At least a portion of the heteroatoms may form part of a chelation complex with some or all of the metal species. In many embodiments, the metal species are present in a sufficient concentration to provide a conductive material, e.g., as a conductive coating on a substrate. The conductive materials may be useful as the thin film conducting or semi-conducting layers in organic electronic devices such as organic electroluminescent devices and organic thin film transistors.
