Abstract: Acicular ferrimagnetic iron oxides are prepared by a process in which iron (III) oxide hydroxide consisting essentially of lepidocrocite is reduced at from 350 DEG to 600 DEG C. by means of an organic compound which is a synthetic polymer with a molecular weight of from 3,000 to 40,000 to give magnetite, which, if desired, is subsequently partially or completely oxidized with an oxygen-containing gas at from 200 DEG to 450 DEG C.

Abstract: THE PRESENT INVENTION RELATES TO THE MANUFACTURE OF SOILID MATERIALS OR SHAPED BODIES CONTAINING AT LEAST ONE ZEOLITE AND BEING AT LEAST PARTLY CRYSTALLINE. FURTHERMORE, THE PRESENT INVENTION RELATES TO THE SOLID MATERIALS OR SHAPED BODIES AS SUCH AND TO THE USE OF THESE MATERIALS FOR REACTIONS OF COMPOUNDS HAVING AT LEAST ONE C-C DOUBLE BOND WITH AT LEAST ONE HYDROPEROXIDE. SPECIFICALLY, THE PRESENT INVENTION RELATES TO A PROCESS FOR THE MANUFACTURE OF A SOLID MATERIAL CONTAINING AT LEAST ONE ZEOLITE AND BEING AT LEAST PARTLY CRYSTALLINE, WHEREIN THE SYNTHESIS OF THE SAID SOLID MATERIAL INVOLVES AT LEAST ONE PARTIAL STEP OF CONTACTING AT LEAST ONE TRANSITION METAL OXIDE SOURCE WITH AT LEAST ONE EPOXIDE OR HYDROLYSATE THEREOF PRIOR TO OR DURING THE AT LEAST PARTIAL CRYSTALLIZATION OF SAID SOLID MATERIAL.
