A catalyst is disclosed for use in the alkylation of benzene with a substantially linear olefin. The container has an upper wall, in which a withdrawal opening is formed which is closed by a tear-off-able lid and a cavity accommodating the stack of products. The average particle size of heat-resisting fine particles which may use SiO2, TiO2, Al2O3, Fe2O3 is 5 nm to 30 \u03bcm. The axle rotates a slotted encoder wheel or a reflective encoder cylinder disposed within the housing so as to accurately determine the axle position and, hence, the active pulse frequency and phase. Further aspects relate to pharmaceutical compositions comprising compounds according to the invention, and the use of said compounds in the preparation of a medicament for treating a variety of disorders, including proliferative disorders, viral disorders, stroke, etc.
