Abstract: A casting process for the preparation of whiteware ceramic articles employs a polyalkylene polyamine, such as tetraethylene pentamine, as an additive to increase the casting rate. The additive can be employed, e.g., in slip casting, vacuum casting and pressure casting. Optionally, the additive includes a binder such as a styrene butadiene latex in an amount effective to maintain the green strength of the articles prepared in the casting process.

Abstract: Alkylated diaryl oxide monosulfonic acids or salts thereof or their mixture are useful as collectors in the flotation of minerals, particularly oxide minerals.

Abstract: A catalytic process for polymerizing epoxides using active hydrogen initiators forming polyols having low unsaturation levels and high primary hydroxyl levels. The catalysts useful in this process are prepared from catalyst precursors exemplified by hydrotalcite. This process is more reactive with less acidic active hydrogen initiators. The polyols can be used in urethanes without removal of the catalyst.

Abstract: Stereoregular, crystalline, isotactic poly(propylene oxide) is prepared using an effective concentration of a hydrotalcite type catalyst in a process conducted above a temperature of about 100.degree. C. and below about 130.degree. C.

Abstract: Halogenated hydroxyquinoline compounds such as 5-chloro-7-bromomethyl-8-hydroxyquinoline are prepared by contacting a 5-halo-8-hydroxyquinoline with formaldehyde to produce a cyclic dioxane and then contacting with concentrated hydrobromic acid to form the desired halogenated hydroxyquinoline compound.The compounds of this invention are usefual as intermediates in the production of ion-exchange resins.

Abstract: A coolant composition for use in automotive engines is disclosed which comprises a liquid alcohol freezing depressant and a corrosion inhibitor consisting essentially of decanedioic acid, dodecanedioic acid and sodium tolyltriazole.

Abstract: Included are the title phosphorate compounds, and a process to prepare them comprising contacting a carbylphosphorate mono acid halide with a carbyloxide. For example, ((2-(3-bromo-2,2-bis(bromomethyl)propoxy)ethyl(chloroethyl)-(ethyl))phosph orate can be prepared with (2-(3-bromo-2,2-bis(bromomethyl)propoxy)ethyl)(ethyl)-chloridophosphorate and ethylene oxide. The compounds are useful so-called flame-retardants for polyurethanes, especially flexible foams because, for example, substantially non-scorching and non-odoriferous flame-retardant flexible foams can be readily prepared with the compounds.

Abstract: Methyl chloride is produced by contacting methanol and hydrogen chloride in the vapor phase in the presence of KZnCl.sub.3 supported on silica. The process produces methyl chloride in good yield with minimal formation of dimethyl ether as a by-product.

Abstract: Chlorinated solvents are removed from vapor vent streams containing the solvent, water and non-condensable vapors by contacting the vent stream with a liquid spray of precooled chlorinated solvent at a temperature less than the freezing point of water. The solid ice floats on the liquid chlorinated solvent and can be readily separated therefrom.

Abstract: A 3-(substituted)-2-oxazolidinone is prepared by refluxing equimolar proportions of a dialkanolamine and dimethyl carbonate in the absence of a catalyst. A yield of at least about 90 percent of a highly pure product is obtained.

Abstract: A method for cyanoisoalkylating phenols or other hydroxy-substituted aryl compounds, which may have up to two substitutents ortho or para to the hydroxy moiety, comprising reacting a molar excess of phenol or aryl compound with a ketone in the presence of cyanide ion and hydroxide ion at an elevated temperature.Compounds, such as 4-(1-cyano-1-methylethyl)phenol, produced via this method are useful as chemical intermediates in the preparation of polyurethanes, epoxy resins and pharmaceutical and agricultural products.

Abstract: Alkenes are prepared by the hydroboration of enamines followed by an elimination reaction to form the alkene. This process has wide applicability and is useful for the stereospecific synthesis of [Z] isomers. It is preferred to use 9-borabicyclo[3.3.1 nonane as the hydroborating agent and to use methanol to catalyze the elimination reaction.

Abstract: A process for the stereospecific synthesis of [E] alkenes from enamines comprising the steps of hydroborating the enamine; esterifying the organoborane so formed and oxidizing the boronic ester in the presence of hydrogen peroxide and in the absence of added base under conditions sufficient to form the [E] alkene in high yield.

Abstract: The corrosion of steel during acid pickling is inhibited by the use of an acid pickling composition containing hydrochloric acid, water and a mixture of a polyalkylene polyamine and a polyglycol in an amount sufficient to inhibit corrosion. A 75:25 ratio of tetraethylene pentamine to polypropylene glycol is particularly effective as a corrosion inhibitor.

Abstract: Aryloxyperfluoroalkyl arenes are disclosed which have relatively low melting points and pour points and are useful as high temperature lubricants. Examples of the invention include 1-(m-phenoxyphenoxy)-2-phenyl-1, 1,2,2,-tetrafluoroethane and 1-(m-phenoxyphenoxy)-2-(m-trifluoromethylphenoxy-m-phenoxyphenoxy)-1,1,2,2 -t etrafluoroethane.

Abstract: Hydroxyaromatic compounds are amido-alkylated or cyano-alkylated to form the corresponding compounds by:(a) heating said compounds with an alkylating agent in the presence of water and a catalyst, e.g., benzyltrimethylammonium chloride;(b) adding an alkaline agent, e.g., NaOH, to the heated mixture of (a); and(c) continuing to heat the resulting mixture until the corresponding amido- or cyano-alkylated compound is formed.Fully or partially amido-alkylated compositions are useful in the preparation of copolymers with epoxy resins.

Abstract: A catalyst, such as FeCl.sub.3, useful in the production of chlorinated hydrocarbons such as 1,1-dichloroethane is removed from the effluent of a process reactor and recycled. Hydrochloric acid is removed from the process stream resulting in the catalyst present in the process stream in solution precipitating out of solution. Then it can be removed from the process stream by conventional separation techniques. Alternatively, the catalyst present in the process stream as a solid, without the removal of HCl, is separated from the liquid present by means of a cyclone and recycled. In both cases, the catalyst retains its catalytic activity.

Abstract: An aqueous composition comprising cement and a mixed metal layered hydroxide which demonstrates thixotropic properties. The mixed metal layered hydroxide is essentially monolayer. An example of such a layered hydroxide useful in this composition is magnesium aluminum hydroxychloride. These cement compositions are thixotropic and shear thinning, harden without settling and do not dewater upon standing.

Abstract: Fumaronitrile or maleonitrile in a nitrile solvent in the presence of a base isomerizes to its geometric isomer. This process is particularly useful for the preparation of maleonitrile by the isomerization of fumaronitrile in acetonitrile in the presence of solid potassium hydroxide. The unreacted fumaronitrile and acetonitrile may be recycled.
