Abstract

A mixed anhydride (claimed per se) is produced by the interaction of a C1- 6 alkyl chlorocarbonate and a C9-27 quaternary ammonium salt of heparin, e.g. the "Hyamine 1622", Hyamine 2389", "Cequartyl BE", "Arquad 2C", or "Zephirol" salt. In Example 5, the "Hyamine 1622" salt of heparin is reacted with ethyl chlorocarbonate in tetrahydrofuran containing a small amount of water. Specification 904,112 also is referred to.
