Abstract: Acylalkylisethionate esters are produced by reacting one or more carboxylic acids with one or more alkyl-substituted hydroxyalkyl sulfonates under esterification reaction conditions. The alkyl-substituted hydroxyalkyl sulfonates used as a raw material in producing the esters are prepared by reacting bisulfate with one or more alkylene oxides. The acylalkylisethionate esters may be used in consumer products.

Abstract: Surfactant compositions including sulfonated polyester polyethers, and methods of making such compositions, are described. A diol is reacted with an anhydride having residual unsaturation, and the resulting polymer is sulfonated under mild acid-base conditions. Sulfonation occurs at the residual unsaturation. If maleic anhydride is used, sulfonation occurs at locations alpha to carbonyl carbons in the polymer.

Abstract: Macrocyclic oxamides may be made easily, in good yield and in one step by reacting an oxalic compound, such as oxalic acid or oxalic esters, with a diamine, where the amine groups are separated by at least five atoms. The oxalic compounds may include, but are not limited to such materials as dimethyl oxalate and diethyl oxalate. The diamines may include, but are not limited to such materials as alkylenediamines; polyalkylene glycol diamines; alkyl-bis-(aminoalkyl)amines; imino bis-(alkyl)amines; and N,N' bis-(aminoalkyl)-N,N'-dialkylalkylenediamines and bis-(aminoalkyl)piperazines; and mixtures thereof. The macrocyclic oxamides made by this process may be used to selectively separate metal ions from solution, or complexed together with a metal ion act as a catalyst.

Abstract: Poly(ethyleneoxy)amines, such as those having the structure:H.sub.2 N--(CH.sub.2).sub.a --(OCH.sub.2 CH.sub.2).sub.b --NH--(CH.sub.2 CH.sub.2 O).sub.c --(CH.sub.2).sub.d --Rwhere a and d are independently 2 to 3; b and c are independently 1 to 4 and R is --OH or --NH.sub.2, may be reacted over a transition metal catalyst such as one containing nickel to produce diaza crown ethers, such as, for example 4,13-diaza-18-crown-6. If the poly(ethyleneoxy)amine is a diamine having a hydroxyl group of the above formula, the reaction may produce the corresponding triamine in the presence of ammonia. These triamines also readily form diaza crown ethers at near complete conversions simply from nickel, platinum, and palladium metal catalysts alone or with other transition metals such as copper and/or chromium. The process avoids tedious, multiple step procedures and the high dilutions that accompany prior diaza crown ether preparations.

Abstract: Disclosed is a two-step method for the preparation of cyclic urea products which comprises: heating a diamine with urea in a mole ratio of about 1 at a temperature from about 120.degree. C. to 140.degree. C. until a mole of ammonia is liberated and slowly heating the intermediate with an alcohol or polyether solvent to a temperature from about 160.degree. C. to 200.degree. C. to produce the cyclic urea products.

Abstract: Disclosed is an improvement in a process for production of cyclohexane by liquid phase hydrogenation of benzene wherein no diluent is necessary, which comprises contacting benzene and hydrogen in the presence of a mixed catalyst bed comprising a first catalyst which is a less active hydrogenation catalyst selected from elements of Group VIII of the Periodic Table and a second, more active catalyst, comprising a Group VIII metal supported on an oxide, such as, for example, alumina, silica or titania at a temperature of about 40.degree. C. to about 300.degree. C. and pressure sufficient to keep the benzene liquid at the chosen reaction temperature.

Abstract: Disclosed is a method for reducing compatibility problems when introducing a polyetheramine having a molecular weight of about 100 to 1000 into a nylon-6,6 polymer by prereacting the polyetheramine with two moles of adipic acid and reacting the adipic acid salt with nylon-6,6 and adipic acid.
