摘要： 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.

摘要： 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.

摘要： Novel polyether amides are produced by reacting a polyethylene glycol diamine and a first dicarboxylic acid or an ester thereof, with a polyoxyalkylene diamine of molecular weight of at least 500 and a second dicarboxylic acid or an ester thereof, where the polyethylene glycol diamine has the formula NH.sub.2 --(CH.sub.2 CH.sub.2 O).sub.x --CH.sub.2 CH.sub.2 --NH.sub.2, where x ranges from 2 to 6, and where the first and second dicarboxylic acid may be the same or different. Suitable dicarboxylic acids include adipic acid, azelaic acid, sebacic acid, dodecanedioic acid, terephthalic acid, isophthalic acid, t-butyl isophthalic acid, and mixtures thereof. Suitable polyethylene glycol diamines include triethylene glycol diamine (JEFFAMINE.RTM. EDR--148 Amine) and tetraethylene glycol diamine (JEFFAMINE.RTM. EDR--192 Amine), among others. Higher molecular weight polyether diamines are used in addition to these polyethylene glycol diamines to give polyether amides useful in making polymers, including fibers, having unusually good water absorbancy properties. The polyether amides are made by mixing equimolar salts of diamine/diacid pairs and then heating the mixture to condense to the polymer.
