Definitions
- the present invention relates to a one-step process for the continuous preparation of siabiie ⁇ dispersions, in particular of wax dispersions having defined particle sizes and narrow particle size distribution in a vortex chamber reactor.
- Dispersions are found in everyday life and in industry in many areas such as the preparation of e.g. of cosmetics, pharmaceuticals, but also in chemical engineering a widespread application. Dispersions are advantageous to the user in comparison to powdery substances. They are pumpable, not dust explosive and not inhalation toxic, less hygroscopic and can be easily incorporated homogeneously in formulations.
- Dispersions are prepared discontinuously (conventionally in a vessel), quasi-continuously or continuously.
- (conventional) static mixers with fixed internals which effect the mixing of fluid streams using the flow energy are used.
- the integrated mixing structures must always be adapted to the dispersing conditions.
- dynamic mixers the homogenization is carried out by turbulent flows, which are generated mechanically by stirrers in a stirred tank.
- the preparation of dispersions, in particular of emulsions, is carried out batchwise, for example, in stirred-cell kettles. It is disclosed in DE-A-29 26 197 that the production of a wax emulsion is achieved by mixing the wax to be emulsified, in particular an acid wax or ester wax based on montan wax, melts, mixed with a saponifying agent, the emulsifier is added and the mixture emulsified by mixing with water with stirring with a stirrer and homogenized.
- suspensions of montan wax are prepared by subjecting the previously comminuted montan wax to an intensive
- the preparation of dispersions may also be carried out using a rotor-stator system, such as, e.g. an Ultra-Turrax or in a high pressure system such as e.g. in high-pressure homogenizers, in a membrane system such as e.g. with a porous membrane contactor or in an ultrasound system, e.g. Ultrasonic homogenizers are performed.
- a rotor-stator system such as, e.g. an Ultra-Turrax or in a high pressure system such as e.g. in high-pressure homogenizers, in a membrane system such as e.g. with a porous membrane contactor or in an ultrasound system, e.g. Ultrasonic homogenizers are performed.
- microstructured apparatus relies on multilamination, in which the fluid streams are each generated in a plurality of microliter-sized fluid laminations, juxtaposed and assembled (US 2006/0 057 485 A1).
- a major disadvantage of these diffusion-controlled mixing processes is the relatively low flow velocity of laminar flows.
- parabolic profiles of velocity are established in the microchannels which no longer have a uniform residence time profile and lead to greatly differing particle sizes.
- EP 1 171 227 B1 describes a combination of multilamination and application of mechanical vibrations for emulsion production. Here, an attempt is made to influence the process of fragmentation and the position of the maximum of the distribution targeted and thus to achieve a narrower distribution of the particle sizes.
- a relatively new process for the preparation of emulsions is the emulsification with porous membranes or perforated inserts, which are integrated in a microstructured apparatus (US 2006/0120213 A1).
- the disperse phase eg oil
- the continuous phase eg water
- the droplets separate from the pores or are torn away from the flow and transported away with the continuous phase.
- Another way to reduce the droplet size of the disperse phase has been described with the incorporation of a so-called shearing turbine blade, a rotating cutting device.
- emulsions with small droplets and narrow drop size distribution can be made in microchannels in this emulsification process.
- high flow rates of the continuous phase are required, which require the use of strong pump units. which are sensitive to shearing, this method is not suitable.
- sintered materials and perforated inserts tend to contamination and blocking.
- the production of these microstructured apparatus is complicated and expensive, usually still in a prototype stage, and only suitable for preparations on a laboratory scale. In practice, however, fluids with different viscosity values are difficult or impossible to coat one another to form fluid lamellae.
- the present invention seeks to provide a technically reliable and cost-effective process for the preparation of dispersions, in particular wax dispersions, with defined particle sizes and narrow particle size distribution, which can be operated continuously and directly linked to the production process, so that a re-melting of the components to be dispersed is saved and ensures good space / time yields.
- the dispersing apparatus used must allow larger throughputs, so that a large-scale implementation is made possible.
- the dispersions should be stable on storage with particle sizes ds 0 of at most 1 .mu.m and narrow particle size distribution (relative span less than 1.0). By relative range we mean the ratio (d 90 - d-io) / dso.
- the present invention is a process for the continuous production of stable dispersions containing dispersed particles of a particle size d 50 of at most 1 micrometer and in a concentration of 1 to 70 wt .-%, preferably 5 to 50 wt .-%, in particular 10 to 40 wt .-%, based on the total weight of the dispersion, characterized in that a) a component to be dispersed (disperse phase) in liquid form by a Nozzle with 1 to 2000 bar, preferably 10 to 200 bar, by means of control valve, extruder and / or pump, for example gear pump or
