摘要： A regioselective acylation process is provided for coverting a 2-methylnaphthalene compound to a 2-acetyl-6-methylnaphthalene compound. The process is conducted under liquid phase conditions in an acylation inert solvent using a complexing agent which is regiospecific for the beta position of naphthalene and which is a thermally stable nitrohydrocarbon compound. Preferred such agents are nitrobenzene, o-nitrotoluene, and mesitylene. Also provided is a novel method for producing a 2-acetyl-6-methylnaphthalene compound of relatively high purity from isomer mixtures by recrystallization from a hydrocarbon solvent, such as n-octane, isooctane, or n-nonane.

摘要： A regioselective acetylation process is provided for converting a 2-methylnaphthalene compound to a 2-acetyl-6-methylnaphthalene compound. The process is conducted under liquid phase conditions using a new complexing agent which is regiospecific for the beta position of naphthalene and which is an electron-rich, carbon-based compound. A preferred such agent is hexamethylbenzene. Also provided is a novel method for producing a 2-acetyl-6-methylnaphthalene compound of relative high purity from isomer mixtures by recrystallization from a hydrocarbon solvent, such as n-octane, isooctane, or n-nonane.

摘要： A method of using a printer system for identifying one or more different types of color objects in a document, selecting a preferred rendering option such as halftoning and/or color matching for each one of such different color object types, respectively, and then printing the document in accordance with the rendering options selected for each of such different color object types. In a printing system such as an inkjet color printer coupled through a printer driver to a host computer, a default halftoning technique and a default color-matching map are incorporated into the printer system for automatic invocation whenever a particular color object type is printed.

摘要： A dual gloss coating is formed on a substrate by first applying to the substrate a continuous layer of curable polyurethane or PVC plastisol or organosol. After the layer is at least partially cured, a second discontinuous layer of the same or different urethane or PVC plastisol or organosol is applied to selected areas of the surface of the first layer by rotogravure printing, using a rotogravure cylinder having a number of lines per inch sufficient to produce a difference in gloss effect between the discontinuous layer and the continuous layer after complete curing of the layers, and then completing the cure of the layers.

摘要： Different print quality modes in a printer such as a color inkjet printer invoke different print rendering options for a particular object to be printed. In an exemplary embodiment, a printer control automatically invokes an error diffusion haltoning technique for photo images whenever high quality mode is designated, and automatically invokes a dither haltoning technique for photo images whenever a normal or fast print mode is designated.

摘要： The present invention relates to commercial and institutional inlaid floorcoverings having a uniform, unpatterned decorative appearance. Colored spheroidal particles having an aspect ratio no greater than about 2:1 are provided in a dense, uniform matrix layer to create the decorative appearance. Flame retardant and smoke suppressant compositions can be incorporated in the floorcoverings without detrimentally affecting their appearance.

摘要： A process is provided for transaralkylating a class of starting compounds comprised of aryl-substituted lower alkanes and aryl-substituted fused alkylene ring compounds to produce derivatives of such compounds wherein benzyl substituents thereof have different alkyl substituents compared to the starting compounds. The process is carried out by admixing such a starting compound with a lower alkyl-substituted aromatic compound under liquid phase conditions in the presence of a catalytically effective amount of a Friedel-Crafts catalyst. The process makes possible new and economical routes for synthesizing desired lower alkyl-substituted benzyl group containing compounds, such as 2,2-di(lower alkyl-substituted) phenyl propanes and 1,3,3-trimethyl-1-(lower alkyl-substituted)-phenyl indans. Thus, there is provided a three-step process for making dixylylpropane from alpha methyl styrene and also a two-step process for making 1,3,3,6-tetramethyl-1-o-xylyl indan from alpha-4-dimethyl styrene. Provided also is a process for preparing 3,3',4,4'-dixylylmethane from a mixture of isomeric dixylylmethanes.
