Definitions

  • the invention relates to unsaturated polyalkylene glycol ethers obtainable by reacting octadienylglycerol ethers with alkylene oxides, a process for their preparation and their use as surface-active agents.
  • unsaturated polyalkylene glycols are liquid or low-viscosity and can be easily processed without excessive heating. They are characterized by excellent emulsifier properties and excellent cleaning action and are therefore used for the production of cosmetic preparations, such as. B. oil bath emulsions, make-up creams, intensive hair treatment or cold wave emulsions [Seif., Oils, fats, waxes, 109, 225 (1983)].
  • the invention relates to unsaturated polyalkylene glycol ethers, obtainable by reacting octadienylglycerol ethers of the formula (I)
  • R * is an aliphatic hydrocarbon radical having 8 carbon atoms and 2 double bonds
  • R 2 and R 3 independently of one another are R 1 or hydrogen and the condition applies that at least one of the two radicals R 2 and 3 must be hydrogen in the presence of a Alkoxylation catalyst with 1 to 20 moles of alkylene oxide per mole of glycerol ether.
  • the invention includes the knowledge that the products according to the invention have good foam, wetting, washing and cleaning properties.
  • Unsaturated polyalkylene glycol ethers within the meaning of the invention which have particularly advantageous performance properties are obtained by reacting monooctadienylglycerol ethers with 2 to 7 moles of ethylene oxide per mole of glycerol ether in the presence of sodium ethylate, sodium hydroxide or hydrotalcite as the alkoxylation catalyst.
  • Octadienylglycerol ethers serve as starting products for the preparation of the unsaturated polyalkylene glycol ethers according to the invention, which in turn represent known substances and can be obtained by the relevant methods of preparative organic chemistry. They are produced from glycerol, which is reacted with 1,3-butadiene in the presence of palladium and triphenylphosphine [DE-B-1807 491]. The octadienylglycerol ethers are obtained as a mixture of the mono-, di- and triether, and their relationship to one another can be influenced by the type and concentration of the catalyst system and the choice of solvent.
  • the aim is to produce the purest possible monooctadienylglycerol polyalkylene glycol ether, it is advisable to fractionate the technical glycerol ether by distillation. In any case, it is advisable to use the 1,3-butadiene in the alkoxylation before the glycerol ether is used in the alkoxylation Separate by-product formed octatriene by distillation.
  • the invention further relates to a process for the preparation of unsaturated polyalkylene glycol ethers, characterized in that octadienylglycerol ethers of the formula (I)
  • R * stands for an aliphatic hydrocarbon radical with 8 carbon atoms and 2 double bonds
  • R 2 and R 3 independently of one another represent R 1 or hydrogen and the condition applies that at least one of the two radicals R 2 and R 3 represents hydrogen must stand, in the presence of an alkoxylation catalyst with 1 to 20 moles of alkylene oxide per mole of glycerol ether.
  • the reaction of hydroxy compounds with alkylene oxides is a large-scale process known per se.
  • the reaction is carried out in the presence of alkoxylation catalysts which can be acidic or basic in nature and can be soluble or insoluble in the reaction product. It has proven advantageous if the alkoxylation in the presence of 0.1 to 5, preferably 0.3 to 1.5 wt .-%, based on the sum of the starting materials, of an alkoxylation catalyst selected from the group consisting of Al - Potassium alkylates with 1 to 4 carbon atoms, for example sodium methylate or potassium tert-butoxide, alkali metal hydroxides, for example sodium hydroxide, alkaline earth metal phenates, such as strontium phenolate, alkaline earth metal phosphates, such as, for. B. barium phosphate and hydrotalcite is formed.
  • hydrotalcite which leads to products with a low residual content of free glycerol ether and a narrow homolog distribution, is particularly preferred.
  • the alkoxylation can be carried out using ethylene oxide and / or propylene oxide (in random or block distribution), one mole of the glycerol being reacted with an average of 1 to 20, preferably 2 to 7, moles of the alkylene oxide. Since the alkoxylation does not provide a uniform product, the ratio of glycerol ether and alkylene oxide only reflects the average degree of alkoxylation. If glycerol ethers which have more than one free hydroxyl group are used in the alkoxylation, the alkylene oxide is more or less statistically distributed over them.
  • the alkoxylation is carried out at temperatures from 100 to 180 ° C and pressures from 1 to 5 bar. To achieve an optimal reaction rate, it is advisable to work at temperatures of at least 150 ° C. Temperatures above 180 ° C. can place a high thermal load on the reaction products and, if appropriate, lead to undesirable discoloration and decomposition.
  • the unsaturated polyalkylene glycol ethers according to the invention are notable for a marked reduction in the surface tension of the water and also promote the wetting of solid interfaces
  • Water are also suitable for emulsifying oils and fats in aqueous systems and can increase the washing power of anionic and nonionic surfactants.
  • the invention therefore also relates to the use of the unsaturated polyalkylene glycol ethers according to the invention as surface-active
  • Example 2 Octadienyl ether + 5 moles of ethylene oxide.
  • Example 2 was repeated using 1.3 g of hydrotalcite as the alkoxylation catalyst. Following the reaction and working up, the catalyst was separated off by filtration. 380 g of a slightly yellow colored liquid were obtained.
  • the ether produced with hydrotalcite as the alkoxylation catalyst showed a lower free glycerol ether content and a significantly narrower homolog distribution.
