  • Publication number: 20240301453
    Abstract: The present invention relates to the field of chemical manufacture. In particular, it relates to a method for manufacturing racemic methylglycinediacetic acid (MGDA) comprising the steps of contacting a solution comprising or being enriched in D-alanine or L-alanine to an alanine racemase at a temperature of at least 50° C. and alkaline conditions for a time sufficient to allow conversion of said solution into a racemic alanine solution, obtaining a racemic alanine solution, and chemically converting the racemic alanine into racemic MGDA. The invention further contemplates an alanine racemase which is capable of converting a solution comprising or being enriched in D-alanine or L-alanine into racemic alanine solution at a temperature of at least 50° C. and under alkaline conditions as well as the use of said alanine racemase for converting a solution comprising or being enriched in D-alanine or L-alanine into racemic alanine solution at a temperature of at least 50° C. and under alkaline conditions.

  • Patent number: 10669380
    Abstract: The present invention relates to amphiphilic star-like polyether. The core molecule is an aliphatic hyperbranched polyether polyol, which is further alkoxylated, first with ethylene oxide or combinations of ethylene oxide and C3-C20 alkylene oxide, preferably propylene oxide, and/or glycidol, and then with a C3-C20 alkylene oxide, preferably propylene oxide, or combination of ethylene oxide and propylene oxide, then optionally anionically modified. The resulting amphiphilic star-like polyether thus has an inner core based on an aliphatic hyperbranched polyether polyol, an inner shell predominantly containing polyethylene oxide units, the inner shell comprising at least 3 ethylene oxide units and an outer shell predominantly containing polypropylene oxide units, the outer shell comprising at least 3 propylene oxide units. They optionally contain anionic groups instead of hydroxyl groups on the periphery of the macromolecule.
