摘要：

A titanium silicate has been synthesized in the presence of tetrabutylphosphonium ions. X-ray diffraction has revealed that this solid was identical to the already reported TS-2, with the MEL structure. The rate of crystallization of the zeolite as well as the maximal amount of Ti atoms that can be incorporated in the lattice are specific of the template. When the synthesis is carried out under stirring conditions, the size of the crystals is comparable to that of a standard TS-2. For similar Ti contents, the catalytic activities and selectivities in the hydroxylation of phenol with hydrogen peroxide are identical.
