摘要:
Bicyclic decanedioic acids corresponding to the following general formula ##STR1## in which R represents a C.sub.1 -C.sub.22 alkyl radical, a C.sub.2 -C.sub.34 alkylcarbonyl radical, or a residue of a polyalkoxylated C.sub.2 -C.sub.22 fatty alcohol, represent a new class of dicarboxylic acids which are useful as flotation aids in the flotation of non-sulfidic ores.
摘要:
The use of a fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of .Iadd.azelaic acid or for the production of .Iaddend.diperazelaic acid .Iadd.from the azelaic acid thus produced.Iaddend., with elimination of enrichment steps with respect to the oleic acid content, by fat splitting, distillation, oxidative ozonolysis of the fatty acid mixture obtained, and .Iadd.in the case of production of diperazelaic acid by .Iaddend.reaction of the azelaic acid thus obtained with hydrogen peroxide to form diperazelaic acid. The resulting diperazelaic acid has improved stability in storage and is obtained in high yields and in highly pure form.

摘要:
A process for the production of free-flowing detergent granules or partial granules comprising the steps of:(a) providing an interiorly baffled, rotatable drying apparatus capable of rotating at high speeds;(b) introducing water-containing alkyl or alkenyl oligoglycoside pastes into the rotatable, drying apparatus;(c) introducing into the drying apparatus detergent components selected from the group consisting of anionic surfactants, nonionic surfactants, detergent builders, and mixtures thereof; and(d) simultaneously drying and granulating the water-containing alkyl or alkenyl oligolycoside pastes and detergent components.
摘要:
A container for the reception of a pumpable product can be emptied cleanly and completely without air contact by a barrel pump and associated follower plate without opening of the container lid when a section of the lid is connected as its circumferential edge by a first frangible line portion, a closure ring placed on the container wall, and a second closed frangible line portion matched to the diameter of a shaft of a barrel pump is provided in the center of the lid. The inner lid portion, bounded by the first frangible line and the second frangible line then forms an accurately fitting follower plate for a barrel pump.
摘要:
Substantially builder-free, liquid, suspension-stable multipurpose cleaning preparations containing abrasives, a surfactant base of mixtures of anionic surfactants or anionic surfactants and amphoteric surfactants, and water, and having a pH-value of from 5.5 to 9.5. These preparations can be used for cleaning hard surfaces of all kinds and in particular can be used as dishwashing detergents, multipurpose cleaners, scouring preparations and/or polishes.
摘要:
Alkyl and/or alkenyl oligoglycosides can be obtained in short reaction times and high yields by a process in which glycose is reacted with fatty alcohols at elevated temperature in the presence of sulfomonocarboxylic acids containing 2 to 8 carbon atoms, carboxylic anhydrides thereof and/or mixed cyclic sulfonic/carboxylic anhydrides thereof as acidic catalysts, the water of reaction is removed and the reaction products are worked up.
摘要:
A foam regulator consisting essentially of a mixture, applied to a particulate support material, of (a) 5 to 60% of a paraffin wax, (b) 20 to 90% of a microcrystalline paraffin wax which shows defined melting behavior as a function of temperature and (c) 5% to 20% of a diamide derived from C.sub.2 -C.sub.7 diamines and C.sub.12 -C.sub.22 fatty acids which is present in the paraffin mixture in very finely divided form. The mixture is preferably prepared by reaction of the diamines with the fatty acids in a molten mixture of components (a) and (b) in the presence of an acidic catalyst.
摘要:
A process for the ozonization of unsaturated organic compounds in a reaction column through which the unsaturated compounds--in solution in a protic solvent--and an ozone-containing carrier gas and an inert coolant are passed downward in co-current flow to provide for an improved coolant effect and an increased ozonization yield where the coolant comprises a compound gaseous or liquid at ambient temperature with a boiling point preferably in the range from +20.degree. C. to -200.degree. C. The boiling point of the coolant is preferably at least 5.degree. C. below the ozonization temperature.
摘要:
A machine washing process with process-controlled dosing of water and detergent using a paste-form, phosphate-reduced or phosphate-free detergent which is substantially free from water, organic solvents and hydrotropic compounds. The paste comprises a phase liquid at a temperature below 10.degree. C. and contains a nonionic surfactant selected from the group of polyglycolether compounds and of a solid phase dispersed therein in which the particles have a mean particle size of from 5 to 40 .mu.m and less than 5% of the particles have a particle size larger than 80 .mu.m, the solid phase comprising washing alkalis, sequestering compounds and other detergent constituents and, optionally, anionic surfactants. Under the control of a process-control computer, the paste is taken from a storage container, delivered to a mixer and diluted therein with water to at least such an extent that the formation of a gel phase is avoided. The aqueous mixture is fed to a washing machine and, unless this has already happened in the mixer, is diluted with more water to a concentration of 0.5 to 10 g/l, after which the washing process is started.
