FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of producing formaldehyde through dehydrogenation of methanol in the presence of an oxide Zn-Na containing catalyst at high temperature. Dehydrogenation of methanol is carried out through chemical conjugation in the presence of hydrogen peroxide taken in an amount which ensures its concentration in methanol of 0.8-1.5%, and in the presence of a catalyst which also contains silicon dioxide with the following initial composition of components, wt %: Na2O - 1.2-1.4; ZnO - 0.8-1.2; SiO2 - the rest, at 790-900C, mainly at 820-850C. ^ EFFECT: invention enables to carry out the process with high formaldehyde output of the catalyst and longer life of the catalyst. ^ 2 cl, 6 ex |
