Efficient, halide- and waste-free production from kg- to ton scale using the patented CBILS® process
Ionic liquids from proionic stand out in particular due to the use of the unique CBILS® production process. The CBILS® process is the world's best industrial production process for a vast group of ionic liquids making cost-efficient production accessible for many of those, or even making production possible exclusively by this method for some.

In addition, using the CBILS® process enables very ecological production of the ionic liquids. Production can be reduced to just a few process steps since with this process elaborate purification processes become needless. There are almost no waste products or pollutants, enabling maximum cost efficiency in production.


Standard liquids

Because of the strengths of the CBILS®, proionic is specialized in the production of imidazolium based ionic liquids such as EMIM (1-ethyl-3-methylimidazolium) and BMIM (1- butyl-3-methylimidazolium) ionic liquids.

Through the years it has been shown, that combinations of the following standard cations and anions are most suitable to meet the demands of almost all our customers.

Choose your cations and anions from the lists of standard ions and put together the desired ionic liquid in a modular system according to your needs.

Standard cations

EMIM (1-Ethyl-3-methylimidazolium)

BMIM (1-Butyl-3-methylimidazolium)

BMPyrr (1-Butyl-1-methypyrrolidinium)

Standard anions

OAc (Acetate)

BF4 (Tetrafluoroborate)

OTf (Trifluormethanesulfonate)

MeSO3 (Methanesulfonate)

TFSI (Bis(trifluormethylsulfonyl)imide)

The resulting ionic liquids are usually on stock and available at short notice, also in large quantities. Minimum order quantity 1 kg.


Tailormade ionic liquids

Our powerful CBILS®-process enables a virtually unlimited combination of cations and anions.

Standard quality (purum):

Assay (HPLC, IC) ≥98%w; halides (IC) <50ppm; water (KFT) <0.5%w; free base (HPLC, T) <0.5%w; aspect clear to faintly turbid

Depending on the type or application of the corresponding ionic liquid, different qualities such as "technical grade, puriss, electronic grade" are offered as well.
