ABSTRACT:
A method of producing substantially spherical lyogels in water insoluble silylating agents is provided. The present invention refers to a method of producing substantially spherical lyogels in which a) a lyosol is provided, b) the lyosol obtained in step a) is transferred to at least one silylating agent in which the lyosol is insoluble, and c) the spherical lyosol formed in step b) is gelatinised in at least one silylating agent in which the lyosol is likewise insoluble, to produce the lyogel.
