    Abstract: Molded bodies having a low content of alkali and alkali earth metal ions can be obtained when in one stage of the process a porous oxide material is mixed with a metal oxide sol and/or a metal oxide. A molded body comprising at least one oxide material and at least one metal oxide is prepared in 5 stages: (i) mixing of at least one metal oxide with at least one metal oxide sol having a low content of alkali and alkali earth metals and/or at least one metal oxide of low alkali and alkali earth metal content; (ii) compaction of the mass; (iii) forming of the mass; (iv) drying of the molded body; and (v) calcining of the dried molded body. Independent claims are included for: (1) A molded body obtained as above; (2) a metal oxide sol having a content of alkali and alkali earth metal ions less than 800 ppm, obtained by hydrolysis of at least one metal acid ester; (3) a process for preparation of at least one alkylene oxide involving the 3 stages: (A) reaction of at least one alkene with hydrogen peroxide in the presence of a molded body obtained as above as catalyst, which can act as catalysts for selective oxidation; (B) preparation of the alkene by dehydration of an alkane; (C) oxidation of the hydrogen produced in (II) to hydrogen peroxide, which is then used in stage (I).
