Mixed metal oxide catalysed and cavitation influenced process for hydration of nitrile

A metal oxide-catalyzed process for hydration of nitrile using a catalyst of formula (I), under the influence of ultrasonic cavitation of Frequency 16-28 khz to achieve the maximum conversion and selectivity at lower temperature (35° C.) comprising:

• heating a reaction mixture of nitrile, solvent, catalyst of formula (I), with or without cavitation influence, at a temperature range of 30 to 140° C. for a time period in the range of 5 to 10 hours (without cavitation and 1 hr with cavitation), to form a respective amide, wherein said nitrile is selected from aliphatic or aromatic nitrile,
• wherein the catalyst of formula (I) is represented as:
• AXBYCZ Formula (I)
• wherein:
• A is a promoter, wherein said promoter is a lanthanide, wherein said lanthanide is selected from the group consisting of divalent metals, trivalent metals and mixtures of oxides of said metals;
• x is the weight % of the promoter in the range of 0.01-99;
• B is a support, wherein said support is a transition element or an inner transition element;
• y is the weight % of catalyst support in the range of 0.01-99;
• C is a co-promoter, wherein said co-promoter is selected from oxides of transition elements having variable oxidation states ranging from 1 to 8 from group number VIII;
• z is the weight % of the co-promoter in the range of 0.01-25;
• and
• x+y≥75 weight %.
