摘要:
Processes for producing branched compounds are described wherein a carbonyl compound is condensed in the presence of a catalyst selected from the group consisting of acids and bases, to form an α,β-unsaturated condensation product; and the α,β-unsaturated condensation product is hydrogenated.

A dispersion including anionic softeners and a process for producing compositions of anionic softeners is provided and obtainable by (a) reacting partial glycerides with maleic anhydride at a temperature above 53° C., wherein maleic anhydride is used in stoichiometric or below stoichiometric quantities to form a reaction product; and, (b) reacting the reaction product with an aqueous solution of sodium sulphite, wherein a quantity of water is selected to form a final product in the form of a 5 to 50 wt % aqueous solution. Powder compositions of anionic softeners may be obtained by drying the final product.
摘要:
Acylamino acids are made by a process which comprises the steps of: (1) introducing a mixture comprised of at least one amino acid or amino acid salt and an alkali source into a reaction zone; (2) adding a mixture comprised of a fatty acid halide of the formula (I): R1COX (I) wherein R1 is an alkyl or alkenyl group having from 6 to 22 carbon atoms and X is chlorine, bromine or iodine to form a reaction mixture while continuously circulating the reaction mixture from the reaction zone through a mixing zone until all of the second mixture has been added to the reaction zone. The process guarantees uniform mixing of the reaction components without the foaming observed without the use of a mixing zone.

摘要:
A composition useful as a parting agent for concrete formwork is provided. The composition comprises water; a completely or predominantly unsaturated fatty alcohol containing 6 to 22 carbon atoms and with an iodine value of 40 to 200; and an alkyl or alkenyl oligoglycoside having an alkyl or alkenyl group containing 4 to 22 carbon atoms, a sugar unit containing 5 or 6 carbon atoms and a degree of oligomerization of 1 to 10. The parting agent is particularly storage-stable at low temperatures.
