Abstract: The invention discloses a composition comprising a hybrid composite organic-inorganic membrane. The hybrid organic-inorganic membrane according to the present invention may comprise an amorphous porous layer incorporating organic functionalities. The amorphous porous layer may be deposited on a porous alumina substrate by chemical vapor deposition (CVD). The amorphous porous layer may comprise a single top-layer (STL), multiple top-layers (MTL) or mixed top-layers (XTL). The substrate may comprise a single layer or multiple graded layers of alumina.

Abstract: A process for the preparation of purified 2,3-pentanedione from lactic compound which is lactic acid or a lactic acid ester. The process uses elevated temperatures between about 250.degree. to 370.degree. C. for heating a support (catalyst 16) and pressures between about 0.1 to 10 MPa to produce the 2,3-pentanedione in a reaction mixture. The lactic compound is converted primarily to 2,3-pentanedione, acrylic acid, and acetaldehyde at the elevated temperatures over the catalyst. The 2,3-pentanedione is preferably separated from the reaction mixture as an azeotrope with water at about 80.degree. to 90.degree. C. and then cooled to separate the 2,3-pentanedione from the water.
