Patent number: 11390834Abstract: The disclosure relates to a reactive distillation method for beverage spirit production, the method comprising. An initial reaction mixture includes water, ethanol, and a carboxylic acid, for example having 3 or more carbon atoms. The reaction mixture is reactively distilled in the presence of an esterification catalyst to react a portion of the ethanol and the carboxylic acid to form an ethyl carboxylate reaction product, and form a distillation product or distillate including water, ethanol, and the ethyl carboxylate. The esterification catalyst is not present in the distillation product, for example when using a solid acid esterification catalyst in the reaction mixture. In a refinement, ethanol and the carboxylic acid can be co-fermented in an initial grain mixture, which is subsequently reactively distilled according to the disclosed method.Type: GrantFiled: March 22, 2019Date of Patent: July 19, 2022Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: Kris A.

Patent number: 6878797Abstract: A process for producing alkali metal polymaleimide salts by alkaline hydrolysis of maleimide polymers prepared by polymerization of maleimide monomers in the presence of a metal oxide and alcohol initiator or a base. In particular, the process produces alkali metal polymaleimide salts with particular ratios of C—N and C—C connected maleimide-derived monomer units which are dependent on the particular initiator used to synthesize the maleimide polymer. The alkali metal polymaleimide salts, which have chelating and anti-scaling properties, are useful as chelating agents and detergent builders and as such are suitable biodegradable replacements for synthetic polymers and sodium polyaspartate.Type: GrantFiled: April 19, 2002Date of Patent: April 12, 2005Assignees: Board of Trustees of Michigan State University, Applied CarboChemicalsInventors: Kris A.

Patent number: 6623657Abstract: Deicing compositions are provided for removing ice from a surface which include either succinic acid or succinic anhydride, or both, and a neutralizing base such as sodium hydroxide, potassium hydroxide, or ammonium hydroxide wherein the deicing compositions when mixed with water produce succinate salts in a reaction that rapidly releases sufficient heat to melt the ice on the surface and the succinate salts act as a deicer and freezing point depressant.
