PREPARATION OF ACYLAMIDE BY CATALYTIC HYDRATION OF NITRILE, CATALYST FOR USE IN SAID PREPARATION AND PREPARATION OF SAID CATALYST |
摘要 |
The invention relates to an improved process for the preparation of acyl amides by subjecting nitriles to hydration in the presence of a copper-containing catalyst. According to the invention hydration is performed in the presence of a catalyst prepared by admixing an aqueous solution comprising an alkali metal vanadate and an alkali metal silicate in a weight ratio of 1 : (1-2.5) with 0.1 to 1.2 moles, calculated for 1 mole of alkali metal silicate, of a water soluble magnesium and/or calcium compound and with a water soluble copper(II) compound to adjust the weight ratio of V<V> : Cu<II>, expressed as metal, to (1:0.3) to (1:4.5), separating the resulting precipitate, admizing 0.7 to 3 parts by weight, calculated for 1 part by weight of Cu<II> ion, of metallic copper to the wet precipitate and drying the resulting mixture at a temperature not exceeding 200<o>C. |
