WebGlyoxal offers some benefits over traditional triazine chemistry as an H2S scavenger [2]. Glyoxal is effective and can be applied in neutral, acidic, and alkaline conditions (pH environment), where triazine is effective and stable only under alkaline conditions. An acidic formulation allows the product to avoid causing carbonate scaling. WebThe simplest of such systems is phenylglyoxal (PhCOCHO), which undergoes H migration to give mandelic acid (PhCHOHCO2 H; 72.5%) on reaction with barium hydroxide. 13,56 Likewise, the reaction of α- (4-isobutylphenyl) β-methyl diketone with 10% aqueous sodium hydroxide–xylene mixture at 100 °C for 5 h affords a 96% yield of α- …
