    摘要： Process for producing acrylonitrile or methacrylonitrile from propane or isobutane by ammoxidation at a temperature in the range of from 380 to 500.degree. C. in a fluidized-bed reactor containing a catalyst composition preheated to a temperature of not lower than 300.degree. C. and lower than the ammoxidation reaction temperature, the catalyst composition comprising a carrier having supported thereon an oxide catalyst comprising a compound oxide of molybdenum, vanadium, niobium and at least one element selected from tellurium and antimony, wherein the ammoxidation of propane or isobutane is preceded by a specific temperature elevation operation in which the catalyst temperature in the reactor is elevated, while supplying into the fluidized-bed reactor a molecular oxygen-containing gas together with a combustible gas capable of combustion by reaction with the molecular oxygen in the presence of said catalyst composition, until the temperature of the catalyst composition reaches said ammoxidation reaction temperature. The process of the present invention is advantageous in that the temperature elevation of the catalyst can be performed without suffering a deterioration of the catalytic activity during the temperature elevation, thereby allowing the catalyst to fully exhibit its performance.

    摘要： Provided is a production method of glycolic acid having a first step of preparing glycolonitrile from formaldehyde and hydrocyanic acid and a second step of hydrolyzing the glycolonitrile into glycolic acid directly or via a glycolate salt, which method can produce glycolic acid in easy production and purification steps while consuming less energy. In the production method, by carrying out the first and second steps continuously or by storing the glycolonitrile obtained in the first step at pH 4 or less and carrying out a hydrolysis reaction of the second step at from pH 5 to 9, a production yield of glycolic acid, activity for the production of glycolic acid and accumulated concentration of glycolic acid are improved, resulting in the production of glycolic acid having an improved purity and quality.
