Abstract
A solution containing lignocellulose material solvated in an ionic liquid that comprises anions and cations. The cation is selected from substituted phosphonium ions having Formula (II), +P[R1 R2 R3 R4], wherein +P stands for a phosphonium ion and each R1, R2, R3, and R4 is independently selected from optionally substituted, linear or branched hydrocarbyl radicals which form a hydrophobic residue. The anions are derived from a Bronsted acid or mixture thereof. The present ionic liquids are capable of phase separation on mixing with water, which allows for separation of the cellulose from the solution and for recovery and recycling of the ionic liquid.
