摘要

1. Claims for the Contracting States BE, CH, DE, FR, GB, IT, LI, LU, NL, SE Novel solid complex which is characterized in that it is formed by alumina bonded to at least one phosphate functional group of a bi- or polyfunctional compound containing at least one phosphate functional group and at least one chemically reactive group capable of forming a covalent bond with molecules of a proteinic nature and particularly enzymes. 1. Claims for the Contracting State AT Process for the preparation of the solid complex formed by alumina bonded to at least one phosphate functional group of a bi- or polyfunctional compound containing at least one phosphate functional group and at least one chemically reactive group capable of forming a covalent bond with molecules of a proteinic nature and particularly enzymes, characterized in that it consists of fixing an organic phosphate which corresponds to formula I or II below : R - O - PO3 H2 R - PO3 H2 in which : R represents an aliphatic or aromatic organic group comprising at least one chemically reactive group such as, in particular, a primary amine, aldehyde or acid group, on alumina, by contacting alumina and an organic phosphate, for a sufficient time, in an aqueous medium, substantially at ambient temperature, at a pH comprised between 2.0 and 8.5.
