Abstract: This invention concerns a new carrier catalyst, the active mass of which contains silver, a process }or its manufacture and a process for the manufacture of ethylene oxide by reacting oxygen-containing gases with ethylene by using the catalyst. This carrier catalyst comprising a carrier material and a catalyst, the active mass of which is 20 to 90 percent by weight of silver, 0.005 to 5 percent by weight of lithium, and 3 to 70 percent by weight of SiO2 in free form or in the form of silicates, is extremely well suited for the manufacture of ethylene oxide by adding oxygen to ethylene.

Abstract: Macromolecular organic compounds (defined as having a molecular weight corresponding to a K-value of 20 or more) are optically brightened by the homogeneous distribution therein of a 1,4-bis-styryl-benzene which contains on at least one benzene nucleus at least one of the substituents, alkyl, aryl, aralkyl, halogen, hydroxyl, esterified hydroxyl and etherified hydroxyl but no nitrile group or carboxylic acid ester or amide group in which the carbonyl carbon atom is attached to the 1,4-bis-styryl-benzene. The bis-styryl-benzenes may be prepared as described in Specification 813,539. An extensive list of macromolecular substances contain various examples of substances within the general categories:-polyamides; polyaldehydes; polyesters; polycarbonates; amino-formaldehyde polycondensates; unsaturated polyester resins; polymers of dienes, vinyl and allyl esters, vinyl ketones, vinyl ethers, olefinic hydrocarbons and their aryl- and halo-substitution derivatives, olefincally unsaturated mono- and di-carboxylic acids and their esters, amides and nitriles, and vinyl pyridine, carbazole and lactams; regenerated cellulose; cellulose esters; rubber; and chlorinated rubber. In specific examples the optical bleaches are incorporated in the following compositions:-(Examples 1 to 4) polyvinyl chloride, ethoxylated maitonic acid and diphenylthiourea; (Examples 5 and 6) polypropylene and titanium dioxide; (Example 7) polypropylene; (Example 8) a polyamide from caprylic lactam; (Example 9) a lacquer of a styrene-butyl acrylate copolymer in toluene; (Example 10) polyvinyl chloride, ethoxylated montanic acid, diphenylthiourea and titanium dioxide; (Example 11) polyvinyl chloride, dioctylphthalate, titanium dioxide and phenylurea; and (Example 12) a styrene-acrylo-nitrile copolymer, titanium dioxide and barium stearate.

Abstract: An antifreeze comprises one or more 1 : 2 diols (ethylene glycol and 1 : 2 propylene glycol), 0.2% borax, 0.1 to 1% sodium nitrate, 0.1 to 1% sodium nitrite, 0.01 to 0.1% sodium silicate, 1 to 4% sodium benzoate and 0.01 to 0.5% benzotriazole, all percentages being by weight based on the diol. The sodium ions may be partially or wholly replaced by one or more alkali metal or ammonium ions. Other materials which may be present are sodium mercaptobenzothiazole, phenylglycine potassium or sodium salt, glycocoll, alanine, isatic acid, isatin, cyclic glycol carbonates derived from ethylene or propylene (1,2-propylene glycol carbonate), aliphatic alcohols (tridecanol), amines (cyclohexylamine) and sodium hydroxide.
