Process for epoxidation and catalyst to be used therein
First Claim
1. An integrated process for treating a solid material comprising at least one zeolite which comprises Ti and being at least partly crystalline, or a shaped body, obtained from said solid material by shaping said solid material into a shaped body, said process comprising:
- bringing said solid material or said shaped body in contact with deionized water at a temperature between 120°
C. and 175°
C. for a duration of 12 to 24 hours afterat least partial crystallization of the solid material containing the at least one zeolite out of a synthesis mixture, resulting in mixture (I) containing the solid material and its mother liquor;
separating the solid material from its mother liquor wherein said separating is a step (II), and calcining the solid material at temperatures higher than 400°
C. wherein said calcining is a step (C);
or afterat least partial crystallization of the solid material containing the at least one zeolite out of a synthesis mixture, resulting in mixture (I) containing the solid material and its mother liquor;
separating the solid material from its mother liquor wherein said separating is a step (II), calcining the solid material at temperatures higher than 400°
C. wherein said calcining is a step (C), shaping the solid material into the shaped body, wherein said shaping is a step (S), and optionally calcining the shaped body wherein said calcining is a step (C).

Abstract
The present invention relates to a process for treating a solid material containing at least one zeolite and being at least partly crystalline or treating a shaped body obtained from said solid material wherein said solid material or shaped body is brought in contact with a composition containing water after at least one of the following steps of an integrated process for producing a solid material or a shaped body containing at least one zeolite: (i) after step (II) of separating the at least partly crystalline solid material from its mother liquor or (ii) after step (S) of shaping said solid material into a shaped body or (iii) after a step (C) of calcining said solid material or said shaped body. The present invention furthermore relates to the solid material obtainable by the inventive process and the shaped body obtainable by the inventive process. The present invention also relates to the use of the solid material or the shaped body as mentioned above as a catalyst in chemical reactions, in particular in reactions of compounds containing at least one C-C double bond with at least one hydroperoxide.
