Abstract: The condensation of an .alpha.-halogen carbonyl compound with carbamic acid esters in the presence of a basic condensing agent and an aprotic solvent enables the production of oxazolinone-2-compounds in a high degree of purity, and in high yields in one step by using simple and readily available starting compounds.

Abstract: Amino resins, e.g., urea-formaldehyde and melamine-formaldehyde thermosetting resin systems, are cured with thermally-decomposable adducts of aromatic sulfonic acids and oxa-azacyclopentanes. The resin products cured with these adducts provide surface coatings having superior water resistance properties. The cured compositions can include other conventional ingredients capable of co-reacting with the amino resins, such as polyols, polyacids, alkyd resins, polyester resins, epoxies, acrylics and the like, to provide compositions curable to products having a wide range of properties.
Abstract: There are disclosed 3-substituted phenyl-5-hydroxymethyl oxazolidinones which possess anti-depressant properties. The compounds are prepared by cyclizing, with ethyl carbonate, 1-substituted phenylamino-2,3-propanediol compounds.
