Abstract:
This invention relates to an improved process for the selective production of N-methyl pyrrolidone (NMP) from gamma-butyrolactone and monomethyl amine preferably in aqueous form in the presence of a catalyst under comparatively milder conditions than the processes well known in the prior art of literature. The process is economically viable as it provides higher yield and selectivity for NMP which reduces the cost of separation of NMP from GBL. The catalyst shows good recyclability without significant loss in catalytic activity and no frequent regeneration is required.

Claim (Index 16):
The process of  claim 11 , wherein the support used in the formulation of the catalyst has Si0 2  to Al 2 0 3  molar ratio of 80 to 90 and specific surface area of 420 to 450 m 2 /g.
