    Abstract: A process is disclosed for preparing products such as 2-hydroxytetrahydrofuran which comprises contacting unsaturated compounds such as allyl alcohol with carbon monoxide and hydrogen in the presence of a rhodium carbonyl catalyst and a ketone solvent system. Allyl alcohol conversions of 100% and selectivities to 2-hydroxytetrahydrofuran of 96% are achievable under certain conditions. Preferred ketone solvents are acetophenone and 2-undecanone. 2-Hydroxytetrahydrofuran is an important precursor to manufacture of 1,4-butanediol.

    Abstract: A method for preparing a nanometal-polymer composite conductive film includes the steps of (1) mixing a metal oxide with a polymer solution; (2) coating a substrate with a solution resulting from step (1), followed by drying the resultant solution to form a film; (3) performing thermal treatment on the film formed in step (2); and (4) sintering the film thermally treated in step (3). The method dispenses with any reducing agent or dispersing agent but allows nanometallic particles to be formed in situ and thereby reduces surface resistance of the polymer film efficiently.

    Abstract: A pigment is dispersed in a solvent by mixing the pigment nanoparticles with clay in a layered or platelet form and mixing the resultant mixture with the solvent. The method is based on geometric inhomogeneity and mutually exclusive aggregation. The layered or platelet clay having a high aspect ratio is provided to hinder aggregation of the pigment nanoparticles. The pigment nanoparticles can be stably dispersed in a matrix containing an organic solvent and water without aggregation again.
