    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an N-alkenylcarboxamide, making it possible to achieve a high conversion and a high selectivity and capable of being performed under the atmospheric pressure, and especially to provide a method for synthesizing N-vinylpyrrolidone(NVP) from N-(2-hydroxyethyl) pyrrolidone(HEP).
    SOLUTION: This method for producing an N-alkenylcarboxamide comprises dehydrating an N-(2-hydroxyalkyl)carboxamide and/or its diether in the presence of a catalyst. Therein, a molecular sieve having a modulus of at least 140, especially zeolite, is used as the catalyst.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for simply producing an alkyl bromide at a low cost, by concentrating aqueous hydrobromic acid during the reaction of an olefin with the aqueous hydrobromic acid. SOLUTION: In this method for producing an alkyl bromide, at the time of producing the alkyl bromide from a mixture containing aqueous hydrobromic acid and an olefin, the existing aqueous hydrobromic acid is concentrated during the reaction. Preferably, the concentration of the aqueous hydrobrmic acid is carried out by a method where the water is removed in the azeotropic mixture form of the water with an organic compound contained in the reaction mixture. The organic compound for forming the azeotropic mixture with the water is prferably cyclopentane, cyclohexane, etc. The reaction is preferably carried at 0 deg.C to the boiling point of the reaction mixture under the atmospheric pressure under the atmospheric pressure, while the reaction mixture is stirred with a mechanical stirring device. The hydrobromic acid is preferably used as an aqueous solution having a concentration of 40-65wt.%. The olefin : hydrobromic acid molar ratio is preferably 0.2:1 to 5:1.
