Provided is a method for producing cyanoacetic acid in a hydrolysis reaction of a predetermined cyanoacetate in the presence of an acid catalyst. Further, are provided methods for producing a cyanoacetic acid derivative and a metal containing compound by using the produced cyanoacetic acid as a staring material. Herein, the method for producing cyanoacetic acid enables the content of a malonic acid byproduct generated in the hydrolysis reaction to be greatly lowered, allowing the produced cyanoacetic acid to be used as a starting material without any purification treatments. Those advantageous effects result in the great improvement in the purity and yields of the cyanoacetic acid derivative and the metal containing compound produced by said cyanoacetic acid. Accordingly, the above mentioned methods make it possible to produce cyanoacetic acid, the cyanoacetic acid derivative and the metal containing compound, as excellent in the productivity and economical efficiency.
提供了一种在酸催化剂存在下,通过水解预定的氰乙酸盐生成氰乙酸的方法。此外,提供了利用生成的氰乙酸作为起始物质来生产氰乙酸衍生物和含金属化合物的方法。在这种生产氰乙酸的方法中,使得在水解反应中生成的丙二酸副产物的含量大大降低,使得生成的氰乙酸可以作为起始物质而无需任何纯化处理。这些有利效果导致了通过该氰乙酸生成的氰乙酸衍生物和含金属化合物的纯度和产量显著提高。因此,上述方法使得能够以高生产率和经济效益生产氰乙酸、氰乙酸衍生物和含金属化合物。
