Abstract: Low foaming beta-amino propionic acid surface active agents are described having the following formula: ##STR1## where R is a C.sub.6 to C.sub.18 aliphatic hydrocarbon radical and n has an average value of from 0 to about 13.The compounds of this invention produce only weak foams as compared with prior art beta-amino acids and have improved solubility and wetting properties over the entire pH range as compared to such prior art beta-amino acids. The compounds of this invention are particularly desirable for use either alone or in combination with other surface active agents and detergents in many washing and wetting applications where foaming is an undesirable characteristic. The compounds are also useful as emulsification agents.

Abstract: A novel, stable, activated silver catalyst useful in the vapor phase epoxidation of ethylene with an oxygen-containing epoxidizing agent is provided. The novel catalyst is prepared by impregnating certain inorganic porous supports with a silver caboxylate/amine complex impregnating solution of a silver carboxylate solubilized in an amine-containing complexing agent selected from:(a) diamines wherein at least one amino moiety is primary or secondary, but no more than one is primary;(b) polyamines containing at least three amino moieties wherein at least one is primary or secondary; or(c) amino ethers containing at least one ether linkage and at least one amino moiety which is primary or secondary;And heating the impregnated support at temperatures of from about 50.degree. C to about 300.degree. C to evaporate volatiles, decompose the complex and activate the catalyst. The novel catalyst shows excellent mechanical strength and superior yield and selectivity in air epoxidation processes.

Abstract: The method of preparing polyurethanes using a catalytic amount of a reaction product of N,N-disubstituted-aminoalkyleneamine with an alkylene oxide is disclosed. These catalysts produce polyurethane products which have no amine odor even immediately after formation of the urethane.

Abstract: A novel cesium modified, activated silver catalyst useful in the vapor phase epoxidation of ethylene with a molecular oxygen containing epoxidizing agent is disclosed. The improved catalyst comprises an inorganic, porous support containing metallic silver and an effective amount of a cesium promoter which have been deposited coincidentally on the support.The catalyst is prepared by impregnating a porous inorganic substrate with a solution comprising solvent, a silver carboxylate solubilized in an amine-containing complexing agent selected from(a) diamines wherein at least one amine moiety is primary or secondary, but no more than one is primary;(b) polyamines containing at least three amino moieties wherein at least one is primary or secondary; or(c) amino ethers containing at least one ether linkage and at least one amino moiety which is primary or secondary;And an effective amount of a salt of cesium; and, heating the impregnated support at temperatures of from about 50.degree. C to about 300.degree.
