Besides aspects in additive manufacturing, particle synthesis and characterization we will present the new SILP technology, which is developed in cooperation with the Institute of particle technology (LFG) and the Institute of Chemical Reaction Engineering (CRT). Future development of more efficient catalysts and adsorbents in continuous processes will depend on the design of solid surfaces that allow all surface atoms to be most effective. At the same time, new technologies are required that will lead to the design of completely new surface properties within solids. Coating of porous solids with a thin film of ionic liquid is a fundamental, new approach to achieve this goal, developed within the last eight years. Ionic liquids are salts consisting completely of organic cations and inorganic or organic anions. Better charge distributions and larger ion sizes lead to melting points below 100 °C. Due to the extremely low vapor pressure of ionic liquids, the surface of SILP materials is coated permanently even under elevated reaction conditions. By variation of anions and cations, solubility, reactivity and coordination properties of the ionic liquids can be changed according to the special requirements of the given process. Depending on the nature of the support, two concepts can be distinguished, namely supported ionic liquid phase (SILP) and solid catalyst with ionic liquid layer (SCILL). The SILP technology involves surface modification of an inert, porous solid by dispersing a thin film of ionic liquid onto it. The SILP material appears macroscopically as a solid, thus, it can be handled like a heterogeneous catalyst and be applied in continuously operated processes.
