Definitions

  • the invention is in the field of oleochemistry and relates to a novel process for working up fatty substances from esterification and transesterification reactions, especially for refining and deacidification.
  • Dry refining uses solid or bound sodium hydroxide. If necessary, soaps are produced as neutralization products in these processes. In contrast, in the wet refining, aqueous caustic soda solution or crystal soda solution and a large amount of water are added, so that subsequent separation of the water is required. In addition, formed soap must be separated by washing several times from the reaction mixture. Subsequently, the reaction product optionally undergoes deodorization, drying and filtration steps.
  • the complex object of the present invention was therefore to develop an improved process for the workup of products from esterification and transesterification reactions for refining and deacidification, which is characterized in comparison to the prior art in that the number of purification steps and the amount of Wastewater is significantly reduced. At the same time, the loss due to product saponification should also be reduced. Finally, the process should be designed so that catalyst contaminants, e.g. Sulfate anions and mono- or polyvalent metal cations can be removed.
  • catalyst contaminants e.g. Sulfate anions and mono- or polyvalent metal cations
  • the invention relates to a process for working up fatty substances from esterification and transesterification reactions, which is characterized in that they are treated with ion exchangers.
  • the advantage of the method according to the invention is in particular that the free acid is bound directly to the ion exchanger by the use of anion exchangers.
  • water is formed only in stoichiometric amounts, which is then removed in the drying process.
  • the complex washing out of the soap and the filtration omitted at the same time the amount of wastewater is significantly reduced. Due to the lower basicity of the anion exchangers and the milder reaction temperatures, there is less loss due to product saponification in comparison to conventional wet refining. At the same time, other interfering anions, especially the undesirable sulfates, are removed.
  • monovalent or polyvalent metal cations can be separated by series connection of cation and anion exchange steps. The regeneration of the ion exchanger is possible as in aqueous ion exchanger systems with dilute aqueous sodium or potassium hydroxide solution and dilute hydrochloric or sulfuric acid.
  • esterification or transesterification products is not very critical to the process according to the invention.
  • glycerides of the formula (I) can be worked up as fatty substances, in the R 1 CO for a saturated and mono- or polyunsaturated acyl radical having 2 to 22 carbon atoms, and R 2 and R 3 are independently hydrogen or saturated and mono- or polyunsaturated acyl radicals having 2 to 22, preferably 6 to 18 carbon atoms stand.
  • Typical examples are vegetable oils such as coconut oil, palm oil, palm kernel oil, olive oil, sunflower oil, thistle oil, rapeseed oil, almond oil and the like.
  • esters of monocarboxylic acids of the formula (II) can also be used as fatty substances, R 4 COO-R 5 (II) wherein R 4 CO is a saturated and mono- or polyunsaturated acyl radical having 2 to 22, preferably 6 to 18 and in particular 12 to 14 carbon atoms and R 5 is a saturated or mono- or polyunsaturated, optionally substituted alk (en) ylrest with 2 to 22, preferably 6 to 18 and especially 12 to 14 carbon atoms or the rest of a (poly) alkylene glycol, especially of ethylene glycol, diethylene glycol, propylene glycol or dipropylene glycol.
  • Typical examples are wax esters based on fatty acids having 6 to 22 and preferably 12 to 18 carbon atoms and corresponding fatty alcohols also having 6 to 22 and preferably 12 to 18 carbon atoms, such as myristyl myristate, myristyl palmitate, stearyl palmitate, stearyl stearate, cetearyl stearate, oleyl oleate and the like.
  • suitable starting materials are esters of dicarboxylic acids of the formula (III) , R 6 OOC- (A) n -COOR 7 (III) in the A for a linear or branched alkylene or alkenylene group having 1 to 10 carbon atoms or a phenyl radical, n is 0 or 1, R 6 and R 7 are independently saturated or mono- or polyunsaturated, optionally substituted alk (en) yl radicals with 2 to 22, preferably 6 to 22 and especially 12 to 18 carbon atoms or the radicals of a (poly) alkylene glycol, especially of ethylene glycol, diethylene glycol, propylene glycol or dipropylene glycol. Typical examples are the stearyl, palmityl or oleyl esters of malonic acid or adipic acid.
  • the starting materials may preferably have acid numbers in the range of 0.5 to 10.
  • ion exchangers for workup and catalysis in aqueous systems are well known in the art, e.g. Softening or desalination of water, recovery of metal. Otherwise, ion exchangers are used in chromatography. In oleochemistry, ion exchangers are used to purify glycerin (desalting). Another application is the use of cation exchangers for acid catalysis in esterification reactions (eg in the preparation of isopropyl myristate / palmitate). However, they have not yet been considered for the deacidification of esterification and transesterification products.
  • anion exchangers or combinations of series-connected anion and cation exchangers, depending on whether only free fatty acids and optionally further interfering anions or, in addition, metal cations are to be separated off.
  • ion exchangers based on polymeric resins and other solid matrices having functional groups are suitable (for example zeolites or oxidic ion exchangers).
  • anion exchangers are polymeric matrices based on polystyrene-divinylbenzene-dimethylamine, polystyrene-divinylbenzene-trimethylammonium chloride or polyacrylodimethylamine, as are commercially available, for example, from Purolite.
  • Typical examples of cation exchangers are polystyrene-divinylbenzene resins having sulfonic acid or carboxyl groups.
  • both weakly basic and strongly basic anion exchangers or strongly acidic or weakly acidic cation exchangers are suitable, with particle sizes in the range from 50 to 1000 .mu.m, preferably between 300 and 800 .mu.m, having proved to be particularly advantageous.
  • the ion exchangers have a range of application between 0 and 200 ° C, depending on the type; Synthetic resin-based cation exchangers can usually be used up to a maximum of 150 ° C. Synthetic resin based anion exchangers are common can be used up to a maximum of 70 ° C.
  • the workup is therefore carried out at temperatures in the range of 0 to 150 ° C, more preferably in the range of 25 to 95 ° C.
  • the anion exchangers can be used directly after conditioning. A drying of the anion exchanger and a pretreatment with organic substances are not necessary for use.
  • the loading capacity of the anion exchangers in the organic system differs only slightly from that in the aqueous system. The regeneration with dilute sodium hydroxide solution can be repeated several times.
