Abstract: Novel compounds are produced from aminated alkoxylated aliphatic alcohols and alkyl phenols are described. The compound is formed by reacting the nitrogen atom with certain compounds to form hydroxyl, carboxyl or sulfonate terminated compounds susceptible to salt formation with Group 1a and 2a metals, particularly sodium and potassium, to increase the water solubility of the compound. These compounds, particularly the salts of these compounds, are useful surface active agents and are soluble in polar and non-polar solvents. They are useful as oil and fuel additives, anticorrosive agents, detergents, froth flotation and oil recovery chemicals, and certain metal salts of the compound are useful as isocyanurate catalysts.

Abstract: Covers a process for preparing a mixture of piperazine and ethylenediamine by the hydrogenation reaction of monoethanolamine and ammonia utilizing a nickel-copper-chromium catalyst. The improvement of the invention involves predetermining the ratio of ethylenediamine to piperazine in the product mix by varying the hydrogen feed rate. Increasing said feed rate causes said ratio to decrease.

Abstract: A process is provided for recovering substantially pure triethylenediamine in liquid lower alkylene diol solutions directly from the crude triethylenediamine reaction mixture without resort to a need to purify the triethylenediamine by crystallization. The process includes initially admixing a lower alkylene diol with a crude triethylenediamine liquid reaction product mixture. The admixture thus formed is then heated to remove water and other low boiling impurities. The crude triethylene diaminediol bottoms mixture is then codistilled to recover a pure triethylene diamine product in diol solvent which can be used directly to catalyze urethane systems.

Abstract: This invention relates to a method for treating wells completed in subterranean formations to form a mechanically stable, permeable mass which permits flow of fluids therethrough into or from the well, while restricting the movement of unconsolidated earth formation particles such as sand into the well. This method is especially suitable for treating producing wells in a subterranean formation being subjected to thermal oil recovery stimulation of viscous oil production such as by steam flooding, which causes rapid deteriation of consolidated sand or gravel masses formed with plastic resins. The method comprises contacting sand with an aqueous solution of calcium hydroxide, plus an effective amount of calcium salt having solubility greater than calcium hydroxide, such as calcium chloride, plus an alkalinity agent such as sodium hydroxide.

Abstract: A highly-active catalyst is prepared by abrading or wearing away the surface of a silver catalyst whereby 1 to about 10 weight percent of the catalyst is removed. The initial silver catalyst is formed, for example, by impregnating a porous catalyst support with a solution of a silver salt an organic amine solubilizing/reducing agent, an aqueous solvent and a cesium or rubidium salt sufficient to deposit on the support an effective amount of the said alkali metal and subsequently heating the impregnated support at an elevated temperature to evaporate volatiles and activate the catalyst.
