    Abstract: PROBLEM TO BE SOLVED: To provide a process for recovering and regenerating ammonia contained in an effluent liquid obtained from a reaction zone for generating a corresponding aliphatic nitrile by reacting ammonia and oxygen with a paraffin. SOLUTION: The process for recovering unreacted ammonia from a reactor effluent liquid obtained from a reaction zone used for generating acrylonitrile or methacrylonitrile comprises a step for quenching the effluent liquid from the reactor with an aqueous solution of ammonium phosphate, where the ratio of an ammonium ion to a phosphate ion in the solution is between approximately 0.7 to approximately 1.3, preferably approximately 0.9 to 1.2.

    Abstract: PROBLEM TO BE SOLVED: To provide an improved catalyst for the catalytic hydrogenation of maleic acid, maleic anhydride or other hydrogenatable precursor to 1,4-butanediol and tetrahydrofuran.
    SOLUTION: The invention is a catalyst essentially comprising palladium, silver, rhenium and iron. Another embodiment of the invention is a method for making such catalyst for the production of 1,4-buthanediol comprising: (i) oxidizing a carbon support by bringing the carbon support contact with an oxidizing agent; (ii) impregnating in one or more impregnation steps comprising contacting a carbon support with a metal source of palladium, silver, rhenium and iron; (iii) drying the impregnated carbon support to remove solvent after each impregnation step; and (iv) heating the impregnated carbon support from ambient temperature to a temperature of between about 100°C and about 350°C under reducing conditions.

    Abstract: PROBLEM TO BE SOLVED: To provide a production process of acrylonitrile or methacrylonitrile, which offers an excellent production rate and an excellent quality of the obtained product without increasing the size of a column used in recovery and purification sections.
    SOLUTION: The process is for the recovery of acrylonitrile or methacrylonitrile obtained from a reactor effluent of an ammoxidation reaction of propylene or isobutylene. The process comprises a step of passing the reactor effluent through an absorber column, a first decanter, a recovery column, a second decanter and a stripper column. The process is improved by maintaining the inside temperature of the first and second decanters at between about 32 to about 75°F.
