METHOD OF PREPARING CATALYST FOR OXIDISING METHANOL TO FORMALDEHYDE |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of preparing a catalyst for oxidising methanol to formaldehyde and its use in formaldehyde synthesis methods. Described is a method of preparing a catalyst for oxidising methanol to formaldehyde, which contains a Fe2(MoO4)3/MoO3 mixture in which atomic ratio Mo/Fe ranges from 1.5 to 5. The method involves reacting powdered iron and molybdenum trioxide in ratio Mo/Fe ranging from 1.5 to 5 in an aqueous suspension at temperature ranging from 20 to 100C and then optional simultaneous oxidation of the mixture with an oxidising agent in an amount equal to or greater than the amount required for oxidising iron (II) to iron (III) and for oxidising molybdenum to molybdenum (VI). Describe is the obtained catalyst and a formaldehyde synthesis method through methanol oxidation using the said catalyst. ^ EFFECT: simple technique. ^ 9 cl, 2 tbl, 3 ex |
