  • PROCESS FOR THE PREPARATION OF THIOL FUNCTIONALIZED HYDROXYALKYL STARCH DERIVATIVES
    Publication number: 20160311933
    Abstract: A process for the preparation of a thiol functionalized hydroxyalkyl starch derivative comprising (i) providing a reaction mixture comprising a solvent, hydroxyalkyl starch, cysteamine and/or cystamine, and a reductive amination agent; (ii) subjecting the reaction mixture provided in (i) to reductive amination conditions, and (iii) subjecting the mixture obtained from (ii) to reducing conditions.

  • HYDROXYALKYL STARCH DERIVATIVES AND PROCESS FOR THEIR PREPARATION
    Publication number: 20130230898
    Abstract: The invention relates to a method for the preparation of a hydroxyalkyl starch derivative which comprises reacting hydroxyalkyl starch (HAS) via the optionally oxidised reducing end of the HAS with the amino group M of a crosslinking compound which, apart from the amino group, comprises a specifically protected carbonyl group, namely an acetal group or a ketal group.

  • METHOD FOR PRODUCING A HYDROXYALKYL STARCH DERIVATIVE WITH TWO LINKERS
    Publication number: 20100297078
    Abstract: A method of producing a hydroxyalkyl starch (HAS) derivative, comprising a) reacting optionally oxidized hydroxyalkyl starch with a compound (D) comprising at least two functional groups —O—NH2 or a salt thereof, and b) reacting the hydroxyalkyl starch derivative obtained in step a) with a compound (L) comprising at least two functional groups W1 and W2 independently selected from the group consisting of an aldehyde group, a suitably protected aldehyde group, a keto group, and a suitably protected keto group.
