Abstract: 7,8-difluoro-2,3-dihydro-3-methyl-4H-1,4-benzoxazine.

Abstract: A method of preparing 7,8-difluoro-2,3-dihydro-3-methyl-4H-1,4 benzoxazine. The method includes the steps of reacting 2,3,4-trifluoroaniline or trifluoronitrobenzene with hydroxyacetone or a derivative thereof under reducing conditions to yield N-(3-hydroxy-2-propyl)-2,3,4 trifluoroaniline. The N-(3-hydroxy-2-propyl)-2,3,4-trifluoroaniline is treated with a base to yield the above-mentioned benzoxazine.

Abstract: This invention relates to a compound of the formula: ##STR1##

Abstract: This invention is a process for preparing 8-sulfo-7-chloro-6-fluoro-4-oxo-1,4-dihydro-3-quinolinic acid wherein the amino analinomethylenomalonate starting material of Formula 1 is unsubstituted at the R.sub.1 and R.sub.2 positions i.e. these moieties are hydrogen. In the ring closing process when R.sub.1 and R.sub.2 are hydrogen, not only does the ring close but the ring position at R.sub.2 is sulfonated.

Abstract: A method of preparing substituted and unsubstituted 1,4-dihydro-4-oxo-2 and -3 quinolinic carboxylic acids which comprises heating an ester selected from the group consisting of substituted and unsubstituted anilinomethylenemalonates, anilinofumurates, anilinomaleates and mixutres thereof in the presence of chlorosulfonic acid, oleum and mixtures thereof.

Abstract: The present invention pertains to a method of preparing substituted and unsubstituted N-hydroxy-2-aminobutane diacid derivatives which can be dehydrated to 2-aminobut-2-ene dioic acid derivatives, which can be subsequently converted to pyridine and quinoline derivatives.

Abstract: The present invention pertains to a method of preparing substituted and unsubstituted N-hydroxy-2-aminobutane diacid derivatives. The invention also pertains to the use of N-hydroxy-2-aminoethane derivatives (including the N-hydroxy-2-aminobutane diacid derivatives) in the preparation of pyridine derivatives.

Abstract: Resin compositions, soluble in odorless mineral spirits, and dryable at room temperature after application to textiles, leather, wood or other surfaces to form soil-oil and water-repellent coatings. The resin compositions are terpolymers comprising a fluoroaliphatic vinyl monomer, a hydrocarbyl higher alkyl vinyl monomer and a polyfunctional vinyl monomer selected from the group consisting of (a) a vinyl amido glycolate ether monomer; (b) a monomeric vinyl diketo ester monomer and (c) a vinyl ester monomer containing hydroxy and halide groups.

Abstract: Resin compositions, soluble in odorless mineral spirits, autooxidizable and air-dryable after application to textiles, leather, wood or other surfaces to form soil, oil and water-repellent coatings. The resin compositions are terpolymers comprising a fluoroaliphatic vinyl monomer, a hydroarbyl higher alkyl vinyl monomer and an acrylic or methacrylic ester of a compound having one or more unsaturated olefinic bonds, which latter ester imparts autoxidizability to the compositions.
