Under the trade name BASIONICS®, BASF offers a portfolio of ionic liquids, mainly based on imidazolium cations. Within the BASIONICS® portfolio, the ionic liquids can be classified as: standard, acidic, basic, liquid at room temperature, and low viscosity products, opening up a wide variety of potential applications. The BASIONICS® portfolio is exclusively available from Sigma-Aldrich in kilogram scale.

BASF works with the following concept: once a customer (either alone or in cooperation with BASF) has identified an Ionic Liquid suitable for a process or an application, the set of specification parameters (purity, by-products, halogen content, color, viscosity, etc.) will be defined in detail. Both the cation and the anion parts of the molecule can be designed to the requirements of the specific application the customer demands. With the given technological expertise in chemical processing as well as existing value chains and raw materials from the “Verbund”, BASF is in a position to make a broad portfolio of Ionic Liquids available in commercial quantities and at reasonable prices.
