Definitions
- the invention relates to a process for the production of concentrated surfactant granules Active substance content of more than 45 wt .-%, based on the granules, which a low hygroscopicity, a significantly improved silage capacity and an increased Have bulk density.
- Granulation is an alternative to spray drying surfactant pastes describes EP-B-0 603 207 (Henkel) a process for the production of washing and cleaning active Surfactant granules with a bulk density above 500 g / l by simultaneous Granulation and drying in all devices in which granulation can be done with simultaneous drying.
- a surfactant preparation form which is a non-surfactant liquid component (usually water) has, if desired granulated with the addition of a solid component and dried at the same time.
- the simultaneous spraying also provides of active substance and carrier component solution through one and the same nozzle here is a possible but not a mandatory process parameter.
- the object of the invention was to provide a method for producing heavy, free-flowing, to provide highly concentrated surfactant granules with bulk densities above 600 g / l, the granules obtained have advantages in terms of ensiling ability and Show hygroscopicity.
- the process according to the invention has the advantage that the resulting grain is conditional due to the inclusion of surfactant phases in phases of the carrier material, an increased mechanical Stability and an extremely reduced water absorption during storage.
- the granules obtained by the process according to the invention are accordingly very easy to pour and ensilage and stick together due to their low tendency to absorb water. With separate injection of active substance and carrier paste in the granulation unit is the product even at low surfactant concentrations sticky and cakes on drying, adding the products are hygroscopic and stick in the course of heavy water absorption.
- the solutions of the active substance and the carrier substance are carried out according to the invention one and the same nozzle atomized.
- the solutions can only be mixed in the nozzle mixed, i.e. fed to the nozzle via separate storage containers and feed lines but also a mixture of both solutions from a single storage container can be injected through a nozzle.
- the non-surfactant solvent which may contain one or more components, has a boiling point or boiling range preferably below normal pressure 250 ° C and especially below 200 ° C. With particular advantage, it contains components which boil between 60 and 180 ° C at normal pressure.
- organic constituents of the non-surfactant solvent are preferably mono- and / or polyfunctional alcohols, for example methanol, ethanol, propanol, Isopropanol, butanol, secondary and tertiary butanol, pentanol, ethylene glycol, 1,2-propanediol, Glycerin or mixtures of these are used.
- the inorganic component of the non-surfactant Solvent water optionally together with organic components such as ethanol, 1,2-propanediol or glycerin.
- the share is of the water preferably 25 to 80 wt .-%, based on the total amount of non-surfactant solvent.
- the solutions of surfactants and carrier materials in Non-surfactant solvents can be used in a wide range of concentrations are taken into account, with only a viscosity that is still suitable for atomization got to.
- the proportion of the non-surfactant is Solvent 30 to 70 wt .-% and in particular 45 to 60 wt .-%.
- alkylbenzenesulfonates ABS
- alkylpolyglycosides APG
- APG alkylpolyglycosides
- APG alkylpolyglycosides
- R is one primary, straight-chain or in the 2-position methyl branched aliphatic radical having 8 to 22, preferably 12 to 18 carbon atoms
- G is a symbol which represents a glucose unit with 5 or 6 carbon atoms
- the degree of oligomerization x between 1 and 10, preferably between 1 and 2 and in particular is significantly smaller than 1.4.
- ABS and / or APG surfactants in addition to the ABS and / or APG surfactants also other anionic, nonionic, cationic or amphoteric surfactants can be used in combination with the former. While the process is mainly used to manufacture ABS and / or APG compounds suitable are additions of up to 20% by weight of other surfactants, based on the total amount of surfactant, possible without losing the advantages of the method according to the invention.
- the carrier materials used in the process according to the invention can be inorganic and / or organic in nature.
