Abstract
Abstract The invention concerns solid complexes for binding hydrocarbons and a process for their preparation. Said complexes are formed by an amine bound to a substrate (clay, glass, organic polymer) through a binding reagent which is an acid chloride. To prepare the complexes, the amine is reacted with the previously activated substrate and becomes covalently bound thereto. The hydrocarbons and other organic materials are bound to the amine by a hydrophobic linkage. Proteins may also be bound to the complex by means of a hydrophobic linkage. The complexes according to the invention are useful in the purification of waters containing hydrocarbons, in the analysis of hydrocarbons, in the separation of proteins, etc..
