    Abstract: A PROCESS FOR PREPARING SALTS OF ACRYLAMIDO-2-METHYLPROPANESULFONIC ACID (A) USING THE STEPS OF: PREPARING A SOLUTION OF A CONTAMINATED SALT OF ACRYLAMIDO-2-METHYL-PROPANESULFONIC ACID (A) IN AN ANHYDROUS ORGANIC SOLVENT (L) USING AT LEAST ONE BASIC COMPONENT (B) SELECTED FROM THE GROUP OF ALKALI METAL OXIDES, ALKALINE EARTH METAL OXIDES, ALKALI METAL HYDROXIDES, ALKALINE EARTH METAL HYDROXIDES AND AMINES OF THE FORMULA (I) NRARBRC (I) WHERE THE RA, RB AND RC RADICALS ARE EACH INDEPENDENTLY: HYDROGEN, C1-C4-ALKYL, HYDROXY-C1-C4-ALKYL OR C1-C4-ALKOXY, WHERE THE MOLAR RATIO OF COMPOUND (A) TO THE BASIC COMPONENT (B) IS 1:1 TO 1:3, RECOVERING THE DISSOLVED SALT OF COMPOUND (A) BY CRYSTALLIZATION OR BY PRECIPITATION, BY ALTERING THE TEMPERATURE AND/OR THE PRESSURE AND/OR THE CONCENTRATION OF THE SALT IN THE SOLUTION. THIS LEADS TO SALTS WHICH ARE LOW IN BY-PRODUCTS AND ARE PARTICULARLY SUITABLE FOR POLYMERIZATION. (FIG. 1)

    Abstract: The present invention relates to a method for preparing 2'-O-fucosyllactose, the 2'-O-fucosyllactose obtainable by this method and the use thereof. The method comprises reacting the persilylated, protected fucose derivatives of the formula (I) below, with at least one tri(C1-C6-alkyl)silyl iodide and subsequently reacting the product thus obtained with the compound of the general formula (II), in the presence of a base. In the formulae (I) and (II), the variables are each defined as follows: RSi are the same or different and are a residue of the formula SiRaRbRc; R1 is a C(=O)-R11 residue or an SiR12R13R14 residue, R2 are the same or different and are C1-C8-alkyl or together form a linear C3-C6- alkanediyl, which is unsubstituted or has 1 to 6 methyl groups as substituents; R3 are the same or different and are C1-C8-alkyl or together form a linear C1-C4- alkanediyl, which is unsubstituted or has 1 to 6 methyl groups as substituents.
