Title ELECTRODE CATALYST AND METHOD FOR PRODUCING AMINE COMPOUND
Abstract An electrode catalyst which is obtained by having an electrode carrier that is composed of a conductive substance support a metal or a metal oxide. It is preferable that: the electrode carrier contains one or more metals that are selected from among transition metals and typical metals in groups 12 to 14, or a carbon material; and the above-described metal or the metal oxide contains one or more metals or metal oxides, which are selected from among transition metals and typical metals in groups 12 to 14.
Outline of related art and contending technology Background Art
Utilization of biomass resources composed of carbon derived from carbon dioxide in the atmosphere is considered to be an effective method of reducing consumption of petroleum resources. In recent years, bioalcohols such as ethanol and ethylene glycol have been industrially produced and have been used as fuels and raw materials.
The inventors have reported a method for producing alcohols by hydrogenating carboxylic acids abundantly contained in biomass resources.
For example, Patent Document 1 proposes a method for synthesizing an alcohol capable of synthesizing an alcohol from carboxylic acids with high selectivity and high yield using a titanium oxide electrochemical catalyst having a specific structure.
Amino acids are used in umami seasonings in the food field, feed additives for livestock, and the like. In recent years, the demand of amino acids has been greatly increased due to the expansion of applications. Currently, amino acids are mainly produced by fermentation.
In the fermentation method, molasses obtained from sugar cane or the like are fermented by microorganisms in the presence of a nitrogen source such as ammonia, and amino acids are separated/purified from the obtained fermentation liquid (, see Non-Patent Document 1, for example,). Fermentation methods have been used for the production of amino acids mainly in the food industry. Fermentation is a cause of global warming, and withset is normally
Solution: a raw material group derived from fossil fuels is not used. In this respect, the fermentation method is expected to be environmentally friendly and sustainable industrial production.
However, when amino acids are produced by fermentation, the following items (1) to (4) have been pointed out.
(1) Sugar which may compete with food edible parts is used as a raw material.
(2) A large amount of energy is consumed for the circulation of oxygen to the fermentation liquid and the agitation of the fermentation liquid performed in the fermentation process.
(3) A large amount of water is used.
(4) It takes time to manufacture.
Examples of methods for producing amino acids other than fermentation methods include chemical synthesis methods (, see Non-Patent Document 2, for example). In the chemical synthesis method, amino acids can be efficiently produced in a short time by using chemicals derived from petroleum as a raw material. As a chemical synthesis method, an amino acid synthesis method using Stoka — Reaction (, Non-Patent Document 3,) is known. In the reaction, ammonia and cyanide are reacted with aldehyde as shown by the following formula (1). Chemical synthesis methods have been used in industrial production of some amino acids.
[Integrated 1]Paternic acid
Several examples of electrochemically performing amino acid synthesis by reductive amination reaction of-keto acid from the latter half of 1 9 5 0 s are reported (, for example, Non-Patent Document 4 However, in any report, Faraday efficiency of electrochemical reaction is 5 0 to 8). In these electrochemical reactions, toxic substances such as lead and mercury are used as catalysts.
