Biomass dissolution kit - six diverse ionic liquids with varied dissolution power and selectivity to biopolymers

Profit from the dissolving power of ionic liquids
proionic's "BIOMASS DISSOLUTION KIT" 550 €* for 6 x 100 g

proionic offers a KIT of six diverse ionic liquids with varied dissolution power and selectivity to biopolymers (see the table below). It also contains second-generation biobased ILs such as Cholinium-L-lysinat or Cholinium acetate, standing out due their high-biodegradability, low toxicity and high enzyme stabilization potential.
Cholinium-L-lysinat (Chol-Lys) (biobased)
Cholinium acetate (Chol-OAc) (biobased)
1-Ethyl-3-methylimidazolium acetate (EMIM-OAc)
1-Ethyl-3-methylimidazolium octanoate (EMIM-OOc)
1-Butyl-3-methylimidazolium acetate (BMIM-OAc)
1-Ethyl-3-methylimidazolium propionate (EMIM-OPr)
