Abstract: Manufacture of high molecular weight unsaturated ketones by reacting allyl alcohols with 1-substituted butadiene-1-alkyl ethers or with 1-substituted butadiene-1-alkyl esters or with substances capable of forming said compounds under the conditions of the reaction, in the presence of acid catalysts at elevated temperatures and in the liquid phase. The resulting unsaturated ketones are precursors or intermediates in the manufacture of a variety of natural dyes such as zeaxanthin, rhodoxanthin and xanthophyll or of odorants such as damascones and damascenones.

Abstract: 2-METHYL-2-HEPTEN-6-ON-1-AL ACETALS AND A METHOD FOR THE PRODUCTION OF THESE COMPOUNDS. The acetals are obtained by reacting the acetals of 2-methyl-4-halo-2-buten-1-al with an alkali compound of an ester of acetoacetic acid and eliminating, by means of an alkali, the alkoxycarbonyl group from the intermediate obtained. 2-methyl-2-hepten-6-on-1-al is obtained from the acetals by acid hydrolysis. The products are perfumes having a pleasant fruity odor and are intermediates for advantageous synthesis of the natural orange aromatics and orange odorants .alpha.-sinensal and .beta.-sinensal.

Abstract: A benzofuran compound of the formula ##SPC1##Where X.sup.- denotes HSO.sub.4.sup.- , CH.sub.3 SO.sub.4.sup.- , Cl.sup.-, Br.sup.-, 1/2 2ZnCl.sub. 4.sup.-.sup.- or CH.sub.3 COO.sup.-. The said compounds are dyes for synthetic textile material.

Abstract: The formation of an emulsion when working up reaction mixtures containing butyraldehydes and cobalt is avoided by a treatment with gases containing molecular oxygen in an aqueous acid medium at an elevated temperature, at least twice the amount of molecular oxygen stoichiometrically required for the oxidation of the cobalt being used per gram atom of cobalt present in the oxoreaction mixture.

Abstract: Glycosides are prepared by reacting a monosaccharide or a compound hydrolyzable to a monosaccharide with 3-chloro-1,2-propanediol in the presence of an acid catalyst producing a 2-hydroxy-3-chloropropyl glycoside. The glycoside is then reacted with a base and an amine having at least one alkyl group that contains 8 to 30 carbon atoms to produce an alkali soluble surfactant.

Abstract: The process for curing polymers with chloronitroso compounds can be accelerated by incorporating metallic compounds as accelerators.

Abstract: The production of dichlorobenzoic acids by reaction of the diazonium compound of a dichloroaminobenzoic acid with an aqueous alcohol solution of specific concentration. The compounds which can be prepared according to the process of the invention are valuable starting materials for the production of pharmaceutical substances, dyes and pesticides.

Abstract: A novel antifreeze composition is provided which comprises a water soluble liquid alcohol freezing point depressant and an inhibitor. The freezing point depressant is preferably at least one water soluble alcohol containing from one to four carbon atoms inclusive and from one to four hydroxy groups inclusive such as ethylene glycol. The inhibitor comprises at least one substance selected from the group consisting ofA. compounds corresponding to the following structural formula: ##SPC1##Wherein R.sub.1 is an alkylene radical containing from zero to 12 carbon atoms inclusive, R.sub.2 is an alkyl radical containing from one to 10 carbon atoms inclusive and R.sub.3 is an alkylene radical containing from one to 12 carbon atoms inclusive, andB. the mono- and di-metal salts, the mono- and di-ammonium salts, and the mono- and di-amides of compounds corresponding to the above structural formula.

Abstract: Finely-divided dispersed solids are prepared by polymerizing in the presence of a free radical catalyst and an organic solvent a major amount of an ethylenically unsaturated monomer or mixture of monomers and a minor amount of a hydroxy-terminated organic compound having from one to eight hydroxyl groups, an equivalent weight of from 500 to 10,000 and containing a polymerizable carbon-to-carbon double bond. The resulting polymeric solids are particularly useful in the preparation of reinforced polymer compositions.

Abstract: Composites based on polyurethane foams heat sealed to a substrate are prepared from polyurethane foams employing a graft polyol as a component of the foam-forming reaction mixture. The resulting composites possess exceptional bonding strength.

Abstract: Lactones of the diazaxanthene series, their manufacture from a benzoylbenzoic acid and a pyrimidine, and their use as dye-forming components in the red range for pressure-sensitive recording material.

Abstract: Novel polyacetal compounds which are useful as surfactants are prepared by a transacetalization reaction. Polyoxyalkylene polymers are acetal terminated by reaction with alkyl vinyl ether compounds. These blocks are then subjected to a transacetalization reaction resulting in polyacetal compounds.
