Abstract: A blend which contains homopolymers useful for imparting wet and dry strength to pulp and paper fibers which comprises a major amount of non-ionic polyacrylamide, together with glyoxal to impart crosslinking and a cationic regulator selected from the group consisting of a low molecular weight dimethyl amine epichlorohydrin copolymer, a low molecular weight ethylene dichloride ammonia condensation polymer, and a polyvinyl benzyl trimethyl ammonium chloride polymer. A buffer such as tetrasodium pyrophosphate may be used. A dosage of 0.2-5% by weight (preferred 0.5-2% by weight) based on the dry weight of fiber is utilized.

Abstract: A method of inhibiting corrosion in separation units of water-free petroleum and petrochemical hydrocarbon processing systems which comprises adding a compound corresponding to Formula I below either alone or in combination with a film-forming amine corrosion inhibitor to the hydrocarbon being processed:Formula IR--O--(CH.sub.2)nNH.sub.2,wherein n is 2 or 3 and R is a lower alkyl radical of not more than 4 carbon atoms.

Abstract: A method of producing tetramethyltin which comprises the steps of:(a) reacting methyl chloride in an ether solvent with a tin-magnesium alloy containing from 1:1 to 1:2 mole ratio of tin to magnesium whereby a substantial quantity of the methyl chloride is converted to tetramethyltin and methyl magnesium chloride, and then(b) electrolyzing the methyl magnesium chloride in an electrolytic cell containing tin anodes whereby additional quantities of tetramethyltin are produced.

Abstract: An improved binder is based upon an aluminum phosphate gelled colloidal silica. The composition of the binder may vary within the following limits (calcined basis):______________________________________ Colloidal Silica 60-85% P.sub.2 O.sub.5 5-35% Al.sub.2 O.sub.3 5-15%.

Abstract: A method of producing a water-in-oil emulsion of ammonium polyacrylate which comprises polymerizing a water-in-oil emulsion of ammonium acrylate in the presence of a water-in-oil emulsifier, and a free radical polymerization catalyst with the amount of oil initially present in said emulsion being at least 15% by weight, continuing said polymerization until substantially all of the ammonium acrylate has polymerized to form ammonium polyacrylate, allowing a major portion of the oil in the oil phase of the emulsion to separate as a polymer-free upper layer, thus leaving as a lower layer a water-in-oil emulsion of ammonium polyacrylate, which emulsion contains less than 10% by weight of oil. Also described are the polymeric emulsions produced using the above described method.

Abstract: A two-step process for removing boron impurities from aqueous solutions of magnesium chloride which comprises treating these solutions with more than 3 moles of methanol in the presence of an acid catalyst to form trimethyl borate and then removing the trimethyl borate and excess methanol from such solutions by means of distillation and then extracting from the thus-treated solutions any remaining boron compounds by means of a hydrocarbon liquid.The hydrocarbon liquid extraction step may be used prior to the methanol treatment.

Abstract: A method for removing boric acid and salts therefrom from ethylene glycol-magnesium chloride solutions which contain at least 100 ppm of boron which comprises reducing the pH of such solutions below 7 and then adding thereto at least 3 moles of methanol based on the amount of boric acid or salt thereof present in said solution and then subjecting the thus-treated ethylene glycol-magnesium chloride solution to distillation at a temperature sufficient to remove trimethyl borate-methanol therefrom, thereby reducing the level of boron in the starting solution to not more than 35 ppm.

Abstract: A composition for inhibiting the corrosion of ferrous metal pipelines used to transport petroleum hydrocarbons comprising a major portion of a mixture of C.sub.36 dicarboxylic dimer acid and a C.sub.54 trimer acid, which mixture has an acid number of at least 110 and from 0.

Abstract: A process of preparing an alkylated phenol which is substantially monoalkylated and para oriented which comprises reacting phenol with a C.sub.4 -C.sub.9 olefin and wherein said olefin is utilized in about 5-10% stoichiometric excess. The broad reaction temperature utilized is about 60.degree.-105.degree. C and the time of reaction is at least 30 minutes. The catalyst utilized is anhydrous H.sub.3 PO.sub.4 which is used in a value of at least 8% based upon the weight of reactant phenol. The preferred products are p-t-amylphenol and p-t-butylphenol, and in the process of preparing these preferred phenols, the olefin may be reacted in 5-8% stoichiometric excess and the reaction temperature utilized may be 95.degree.-115.degree. C. An additional preferred product is p-nonylphenol derived from a branched propylene trimer.
