Ionic liquids: Synthesis and characterisation of triphenylphosphonium tosylates

Ionic liquids are currently attracting considerable interest from chemists, partly due to their potential as "green" alternatives to volatile molecular organic solvents. Phosphonium ionic liquids have received much less attention than ammonium salts in th

Quaternary phosphonium salt flame retardant and synthesis method and application thereof

The invention provides a quaternary phosphonium salt flame retardant and a synthesis method and application thereof, and the method comprises the following steps: by taking an acidic compound, ortho-formic acid trisubstituted ester and an organic phosphine compound III or IV as raw materials, carrying out a one-step reaction process to prepare the quaternary phosphonium salt flame retardant I or II. The flame retardant disclosed by the invention has good thermal stability and has an excellent flame-retardant effect when being applied to various polymers. The method is simple and convenient insynthesis operation, low in raw material price, mild in synthesis condition and high in yield. According to the synthesis method, introduction of halogen ions is avoided, and dozens of anions are successfully introduced. By adding a small amount of the flame retardant, the obtained PC flame-retardant composite material UL-94 can reach the V-0 grade.

Clean catalysis with ionic solvents - Phosphonium tosylates for hydroformylation

High-melting phosphonium tosylates are synthesised and applied for the first time as solvents in catalytic hydroformylation reactions; variation in the substituents attached to phosphorus can lead to markedly different results; the catalyst systems are non-corrosive, easily manipulated and can readily be recovered and reused.
