12 Claims

1. A continuous process for preparing a zeolitic material having an MFI framework structure type comprising TS-1, comprising Si, Ti, and O, said process comprising

(i) preparing a mixture comprising one or more sources of Si, one or more sources of Ti, one or more tetraalkylammonium cation R¹R²R³R⁴N⁺-containing compounds as structure directing agent, and water;

(ii) continuously feeding the mixture prepared in (i) into a continuous flow reactor; and

(iii) crystallizing the zeolitic material having an MFI framework structure type, wherein the mixture is heated to a temperature in the range of from 130 to 220° C., wherein R¹, R², R³, and R⁴independently from one another stand for alkyl, and wherein the H₂O:Si molar ratio of water to the one or more sources of Si calculated as SiO₂in the mixture prepared in (i) is in the range of from 3 to 11;

wherein the mixture constituting the feed crystallized in (iii) consists of a first liquid phase and a second liquid phase, wherein the first liquid phase is an aqueous phase comprising water, and the second liquid phase comprises a lubricating agent;

wherein the lubricating agent comprises one or more fluorinated compounds or a liquid paraffin.
