Definitions
- the invention relates to amino acid group-containing organosilicon compounds and a simple process for their preparation and their use.
- Amino-containing organosilicon compounds play an important role in the art.
- po ⁇ stellar amino group in a polysiloxane, for example, the interaction with polar surfaces, and thus the adhesion of the polysiloxane is greatly increased.
- amino acid-functionalized Organosiliciumverbin ⁇ tions are technically highly interesting, since even higher polarity can be achieved by the additional presence of the carboxylic acid grouping.
- Amino groups are present in the iA betaine, which electrostatic interactions are much more pronounced than in the amino group-containing organosilicon ⁇ .
- amino acid-functionalized polysiloxanes are already known. Of particular interest, however, are amino acid-functional organosilicon compounds in which the basic character of the amino groups p réelle and consequently the amphoteric character of the amino acid moiety is retained after the linkage with the polysiloxane. This is especially the case when the amino acid is linked to the polysiloxane by addition to a reactive epoxide grouping on the polysiloxane.
- JP 52-114699 also describes the reaction of carboxy-protected amino acids using an epoxy-functional trisiloxane.
- EP 2826806 describes the preparation of amino acid- modified siloxanes from organic amino acid salts, in which the counterion to the carboxylation of the amino acid is an organic cation, eg a quaternary ammonium or phosphonium cation with a long-chain alkyl radical.
- the preparation of these amino acid salts already requires two conversion ⁇ steps of: in a first step, the amino acids are in the In a second step, the reaction with the quaternary ammonium or phosphonium chloride to form potassium chloride, which can be precipitated and separated by dispersing in a suitable medium. This method is therefore both costly and expensive.
- quaternary ammonium and phosphonium compounds are toxicologically questionable, thereby reducing the possible range of application of the compounds.
- a great advantage would therefore be a method in which the technically available free amino acids could be used directly without prior conversion to salts. This would then also be opened up amino acid-functional organosilicon compounds containing unprotected carboxyl groups and thus show more pronounced properties of an amino acid grouping.
- EP 2231753 describes the reaction of epoxy-functional polysiloxanes with free amino acids in an aqueous emulsion in the presence of about 25 to 28% by weight emulsifier. The mixing of the usually extremely viscous emulsions poses a high technical challenge for the
- the formed amino acid-group-carrying siloxane always falls in admixture with emulsifiers, which can not be separated from the product due to their similar properties.
- the amino acid-functionalized organosilicon compounds can therefore not be isolated in pure form according to this instruction. This limits the application ⁇ region of amino acid-functional polysiloxanes significantly.
- the emulsifier components may interfere with further use or even prohibitively.
