An adhesive composition comprising 10 to 80% by weight of a binder composed of an aminoalkyl ester group-containing acrylic copolymer shown ##STR1## wherein R denotes an alkylene possessing 2 to 3 carbon atoms, as a pendant group and an epoxy resin, and if desired a rust-proofing pigment and a silane coupling agent.

Adhesive composition

A silver catalyst having fine silver particles dispersed and deposited fast on the outer surface of a porous inorganic refractory carrier and on the inner wall surface of pores in said carrier and used in the production of ethylene oxide by the catalytic gas-phase oxidation of ethylene with molecular oxygen, which silver catalyst is characterized by containing a compound of at least one metal ion selected from the group consisting of cesium, rubidium, potassium, and thallium (monovalent) as dispersed and deposited fast in an amount in the range of 1.times.10.sup.-6 to 5.times.10.sup.-6 gram equivalent per the unit surface area, m.sup.2, of said silver on the surface of said silver.

Silver catalyst for production of ethylene oxide and method for

Diisopropyl ethers of oligomers of ethylene glycol having between 2 and 8 ethylene glycol moieties and an average molecular weight between 190 and 300, are more useful physical absorption solvents for the separation of acid gases than are dimethyl, diethyl, ethyl butyl, propyl butyl, dibutyl, or higher alkyl ethers of the same ethylene glycol oligomers, because of a combination of high solution capacity, high separation efficiencies, low viscosity, low gas pressure, and resistance to hydrolysis during use. The diisopropyl ether of diethylene glycol is especially advantageous for use at absorber temperatures below 0.degree. C. Because of low viscosity, the diisopropyl ethers can often be substituted in separation equipment designed for use with chemical rather than physical solvents, thereby realizing the lower operating costs associated with physical solvents without requiring new capital investment.

Process for separation of carbon dioxide from other gases

A method for the production of an aqueous dispersion of a water insoluble N-substituted N',N'-alkylene urea having the general formula I: ##STR1## wherein R.sup.1 denotes alkyl having 6 to 20 carbon atoms, phenyl or ##STR2## in case of m=1, or R.sup.1 denotes alkylene having 6 to 20 carbon atoms, phenylene or ##STR3## in case of m=2, where X denotes H, CH.sub.3 or OCH.sub.3 and n is 0 or 1, R.sup.2 denotes H or CH.sub.3, R.sup.3 denotes H, CH.sub.3 or C.sub.2 H.sub.5 and R.sup.4 denotes H or CH.sub.3, by the reaction of an alkylene imine having 2 to 4 carbon atoms with an isocyanate represented by the general formula II:

Method for production of aqueous dispersion of N-substituted

A silver catalyst for the production of ethylene oxide by catalytic vapor phase oxidation of ethylene with molecular oxygen in the presence of a halogenated inhibitor, having silver and at least one accelerator selected from the group consisting of alkali metals and alkali metal compounds deposited on a porous inorganic refractory carrier in the shape of Intalox saddles or Berl saddles, and the method for manufacture thereof.

A process for the production of alkylene glycols, which comprises causing a corresponding alkylene carbonate to react with water in the presence of a catalyst of at least one member selected from the group consisting of molybdenum and tungsten.
