1-Butyl-3-methylimidazolium hexafluorophosphate Specification

The 1-Butyl-3-methylimidazolium hexafluorophosphate, with the CAS registry number 174501-64-5, is also known as 3-Butyl-1-methylimidazolium hexafluorophosphate. It belongs to the product categories of Imidazolium Compounds; Imidazolium Salts (Ionic Liquids); Ionic Liquids; Synthetic Organic Chemistry; Ionic liquid. This chemical's molecular formula is C8H15N2.PF6 and molecular weight is 284.18. What's more, its systematic name is 1-Butyl-3-methyl-1H-imidazol-3-ium hexafluorophosphate. This chemical is a viscous, colourless, hydrophobic and non-water soluble ionic liquid. Together with 1-butyl-3-methylimidazolium tetrafluoroborate, BMIM-BF4, it is one of the most widely studied ionic liquids. It is known to very slowly decompose in the presence of water.

Preparation: this chemical can be obtained in two steps: BMIM-Cl is synthesized by alkylating 1-methylimidazole with 1-chlorobutane. A metathesis reaction with potassium hexafluorophosphate gives the desired compound; the tetrafluoroborate may be prepared by analogously using potassium tetrafluoroborate.

When you are using this chemical, please be cautious about it as the following:
This chemical is irritating to eyes, respiratory system and skin. It is harmful if swallowed. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. When using it, you need wear suitable protective gloves and eye/face protection.
