Synthesis of glyoxylic acid from carbon dioxide, carbon monoxide and hydrogen
The synthesis section of this article in essence shows three industrial or manual methods. I wonder if carbon dioxide, carbon monoxide and hydrogen can make glyoxylic acid ? Those three chemicals can be found in syngas with water as another component. So in essence such synthesis create a path to convert unused industrial gases from petrochemical industry to biodegradable products. --- Mountainninja (talk) 01:25, 8 June 2014 (UTC)
 * One way to evaluate the idea is to compare the heat of formation of glyoxalic acid and the components you suggest. The hydrogenation of CO2 to HCO2H is uphill at STP, I am pretty sure. The process might be uphill, I dont know.  The hydrogenation of CO and CO2, as you seem to be aware, are practiced industrially in the Fischer-Tropsch and methanol syntheses.  --Smokefoot (talk) 06:36, 8 June 2014 (UTC)
 * Thank you for your input. In gasification, those three chemicals can be converted into glyoxylic acid, with water and nitrogen returning respectively to earth and the atmosphere. The gasification can help popularize the process and could return the glyxoxylic acid to the neighborhood as a merchandise, for example alkali metals, alkaline earth metals or ammonium glyoxylates in road salt.
 * Mixing the three gases could result in making carbon monoxide and water, moving towards making the undesired formic acid. Probably the formaldehyde made from H2 and CO without going all the way to methanol can be used to react with CO2 to make the acid. Hydroformylation of carbon dioxide is an one step synthesis of the acid but can a catalyst be found ? Regardless the heat of synthesis shall come from other cogenerating processes. Gasification of municipal solid waste could generate more than enough heat to drive the synthesis because the resulting syngas is burnt to produce electricity and only unused but hot gases are converted using some kinds of heat recovery. - Mountainninja (talk) 13:50, 8 June 2014 (UTC)
