Definitions

  • the invention relates to a process for the preparation of surface-active compounds with improved cleaning performance / in which aqueous pastes of alkyl and / or alkylene oligoglycosides are subjected to hydrolysis at elevated temperature and, if appropriate, under pressure.
  • Alkyl oligoglycosides in particular alkyl oligoglucosides, are nonionic surfactants which, due to their excellent detergent properties and high ecotoxicological compatibility, are becoming increasingly important.
  • native raw materials such as fatty alcohol and sugar or starch syrup, which are acetalized in the presence of acidic catalysts.
  • German patent application DE-Al 41 17 689 (Henkel) has proposed that small amounts of anionic surfactants be added to the aqueous alkyl oligoglucosides to optimize performance.
  • this is associated with an additional method step and is therefore not very desirable.
  • the object of the invention was therefore to provide a process which ensures the production of alkyl and / or alkenyl oligoglycosides of a consistently high technical quality.
  • the invention relates to a process for the preparation of surface-active substances with improved cleaning performance, in which aqueous pastes of alkyl and / or alkenyl oligoglycosides of the formula (I),
  • R 1 is an alkyl and / or alkenyl radical having 4 to 22 carbon atoms
  • G is a sugar radical having 5 or 6 carbon atoms
  • p is a number from 1 to 10, at temperatures from 70 to 180 ° C. and Pressures from 1 to 50 bar subject to hydrolysis over a period of 5 minutes to 10 days.
  • aqueous alkyl and / or alkenyl oligoglycoside pastes guarantees an improvement in the rinsing and cleaning performance of batches of otherwise inadequate quality.
  • the invention is based on the knowledge that the heating of the aqueous pastes results in hydrolysis or liquefaction of less wash-active higher molecular weight and, if appropriate, crystal water-containing aggregates, which has an advantageous effect on the detergent properties of the products. Furthermore, partial oxidation of the sugar body with the formation of anionic surfactants can occur, albeit to a lesser extent, which also contribute to the effect described above.
  • Alkyl and alkenyl oligoglycosides are known substances which can be obtained by the relevant processes in preparative organic chemistry. Representative of the extensive literature, reference is made here to the publications EP-Al-0 301 298 and WO 90/3977.
  • the alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose.
  • the preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides.
  • the alkyl or alkenyl radical R can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxo synthesis.
  • the alkyl or alkenyl radical R x can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, Stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, and their technical mixtures, which can be obtained as described above. Alkyl oligoglucosides based on hardened C 12 14 coconut cono with a DP of 1 to 3 are preferred.
  • aqueous pastes of the alkyl and / or alkenyl oligoglucosides are usually used as the starting point. It is not critical whether finished preparations are subjected to a subsequent heat treatment or whether practically anhydrous products are mixed with water and hydrolyzed immediately after production.
  • Aqueous pastes which have a solids content of 10 to 99, preferably 30 to 70 and in particular 50 to 60% by weight, based on the paste, are advantageously used.
  • the parameters water content, temperature, pressure and residence time are related. For example, products of the desired, consistently good quality can be obtained both at high temperatures and short residence times and at low temperatures and long residence times. With increasing water content, either the temperature or the residence time can be reduced. Finally, working under pressure makes it possible to reduce at least one of the three other parameters and, in particular, to set short dwell times. This embodiment is therefore preferred for economic reasons.
  • pastes with a solids content of 10 to 20% by weight (i.e. a water content of 80 to 90% by weight) and over a period of 1 to 10 days to 70 to 90% ° C to heat. This can be done, for example, in a stirred kettle, an inert gas covering counteracting oxidative damage and undesired discoloration of the product.
  • the pressure hydrolysis can be carried out discontinuously in an autoclave, but preferably continuously, for example in a residence time queue. It has proven to be optimal to hydrolyze pastes with a solids content of 70 to 90% by weight (water content 10 to 30% by weight) at 70 to 150, preferably 90 to 130 ° C., the residence time being 5 to 120, preferably 15 to 60 minutes. Usually the hydrolysis takes place under autogenous pressure, i.e. H. at pressures of 2 to 25, preferably 5 to 10 bar.
  • alkyl and / or alkenyl oligoglycosides obtainable by the process according to the invention are distinguished by consistently good detergent properties. They are therefore suitable for the production of detergents, dishwashing detergents and cleaning products and products for hair and body care, in which they can be present in amounts of 1 to 50, preferably 10 to 30,% by weight, based on the composition.
  • Solids content 50% by weight
  • a freeze-dried coconut alkyl oligoglucoside (B) was diluted with water of hardness 0 ° d to a paste concentration of 50% by weight and then at 150 to 180 ° C in a continuous pressure hydrolysis coil (residence time 15 to 120 min, pressure 10 bar, pastes Bl to B5) hydrolyzed. The rinsing performance was then examined in a plate test. The rinsing capacity of the paste before hydrolysis was 8 people. The results are summarized in Table 2.
