Definitions
- the invention relates to a process for the preparation of solid formulations of the sodium salt of 3-hydroxy-3-methylbutyric acid ( ⁇ -hydroxy- ⁇ -methylbutyric acid, HMB) of the formula
- 3-Hydroxy-3-methylbutyric acid is an active ingredient that is used as a medication and nutritional supplement for humans and animals, for example to lower the cholesterol content in the blood (WO-A-94/06417) or to reduce the nitrogen excretion, especially in sick and / or old people (WO-A-94/14429).
- a physiologically acceptable salt for example the calcium salt, is used for this.
- the object of the present invention was therefore to provide a simple and economical process for producing a storage-stable, solid (powdery) and less hygroscopic form of sodium 3-hydroxy-3-methylbutyrate.
- silica especially the commercial Desillungskiesel- suitable acids such as those available from Degussa under the name Sipernat ® commercially, for example.
- the solution of sodium 3-hydroxy-3-methylbutyrate is preferably brought to a concentration of at least 50% by weight, particularly preferably 70 to 80% by weight, by distilling off water under reduced pressure. At the latter concentrations, the solution is expediently kept at a temperature of 60-65 ° C. in order to prevent crystallization. Concentration can be carried out on a laboratory scale, for example in a conventional distillation apparatus, or on an industrial scale, for example in a thin-film evaporator. However, it is also possible to directly use the solutions obtained in the synthesis with contents of, for example, 20 to 30% by weight.
- the solution of sodium 3-hydroxy-3-methylbutyrate can be drawn up in a conventional mixing device; a gentle mixer type, for example a drum, ploughshare or cone mixer, a spray mixer or else a (slow-running) intensive mixer, is preferably used for this , Too violent mixing can surprisingly lead to clumping.
- a gentle mixer type for example a drum, ploughshare or cone mixer, a spray mixer or else a (slow-running) intensive mixer, is preferably used for this , Too violent mixing can surprisingly lead to clumping.
- the pull-up is preferably carried out in such a way that the synthetic silica is initially introduced and the solution of sodium 3-hydroxy-3-methylbutyrate is metered in.
- hydrophobic silica for example Sipernat Dl 7
- another flow improver can optionally be added to the product produced according to the invention.
- amounts of 0.2 to 0.4% by weight based on the dry substance, of hydrophobic silicic acid are added towards the end of the mixing process and mixed in for a short time (for example 30 minutes).
- compositions obtainable by the process according to the invention which contain sodium 3-hydroxy-3-methylbutyrate and synthetic silica, are also the subject of the invention.
- compositions according to the invention preferably contain, based on the dry substance, at least 25% by weight of sodium 3-hydroxy-3-methylbutyrate, particularly preferably 25 to 50% by weight.
- Example 2 The solution from Example 1 was concentrated at 50 mbar and 56 ° C. to 57.5% by weight. 50 g of synthetic silica were placed in an Eirich intensive mixer (type R02)
