  • Publication number: 20190292501
    Abstract: 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.

  • Patent number: 8981166
    Abstract: An improved process for extracting fusel alcohols and/or fusel alcohol esters from an ethanol fermentation product involves adding to the fermentation product an extractant solvent selected from amyl alcohols, amyl acetates, and mixtures thereof to produce a two-phase system including a water and alcohol phase, and an immiscible second phase comprised of amyl alcohols, amyl acetates or a mixture thereof. Thereafter, the first and second phases can be separated to obtain a first phase depleted of fusel alcohols and/or esters of fusel alcohols and a second phase containing fusel alcohols and/or esters of fusel alcohols extracted from the first phase.

  • Publication number: 20050142219
    Abstract: A potassium salt composition from seaweed, methods for producing the composition, and methods of using the composition of an essentially sodium-free salt substitute and/or potassium dietary supplement is described. The potassium salt composition has a pleasant salty taste and has a crystalline appearance that resembles regular table salt, but it is essentially free of the sodium and the metals. In addition, the product is essentially free of seaweed aromas or flavors which are removed by absorption or adsorption from an aqueous solution containing the dissolved potassium salt substitute.

  • Patent number: 6878797
    Abstract: 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.

  • Patent number: 6623657
    Abstract: 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. In particular embodiments, the deicing compositions further include a glycol which inhibits reformation of the ice on the deiced surface. The deicing compositions are suitable and effective for airport applications in which corrosion of aircraft alloys and concrete runways are of concern.

  • Patent number: 6287480
    Abstract: Improved deicing compositions and methods are provided. In particular, the subject invention is directed at deicing compositions which are suitable and effective for airport applications in which corrosion of magnesium based alloys is an issue. In particular, the invention is directed at deicing compositions which are less corrosive of steel and aluminum and certain magnesium based parts than conventional road salt. For example, the invention is directed to deicing compositions which are substantially less corrosive than allowed for use on aircraft metal parts, such as magnesium based alloys unlike acetate and formate salts. The subject invention is also directed at deicing compositions which inhibit the corrosive effects of conventional road salt. The subject invention is also directed at deicing compositions comprising effective deicing amounts of succinate salts, such as potassium succinate (trihydrate), ammonium succinate (anyhdrous), sodium succinate (hexahydrate), either alone or in combination.
