摘要: A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from Acidovorax facilis 72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.
摘要翻译: 提供从甲醛和氰化氢生产乙醇酸的方法。 更具体地,使热处理的甲醛和氰化氢反应以制备具有低浓度杂质的乙醇腈。 随后使用具有源自Acidovorax facilis 72W(ATCC 57746)的腈水解酶活性的酶催化剂将乙醇腈转化为乙醇酸铵水溶液。 使用本文所述的各种方法,从乙醇酸水溶液中以酸或盐的形式回收乙醇酸。
