A simple, high-yieldsynthesis is described that leads to the sodium salt of monosulfonated triphenylphosphane (TPPMSNa) as a pure product in large quantities without complicated workup techniques, The single-crystal X-ray structure of TPPMSNa center dot 2.5H(2)O is reported. The structure is built up by alternating layers of aquated sodium sulfonate units and hydrophobic triphenyl units. Thermogravimetric

A process for polymerizing at least one fluoromonomer in an aqueous medium containing initiator and hydrocarbon dispersing agent to form an aqueous dispersion of particles of fluoropolymer. The hydrocarbon dispersing agent comprises a compound of formula I: R --- (XZ)n(I) wherein R is a hydrophobic hydrocarbon moiety that comprises one or more saturated or unsaturated, non-cyclic or cyclic aliphatic groups, the percentage of total CH3groups in relation to the total of CH3, CH2and CH groups in said one or more aliphatic groups being at least about 70%, said hydrophobic moiety being free of siloxane units; wherein each X may be the same or different and represents an ionic hydrophilic moiety; wherein each Z may be a same or different and represents one or more counter ions for said ionic hydrophilic moiety; and wherein n is 1 to 3.

The compound is useful as a ligand in transition metal-ligand complex catalysts that are capable of catalyzing the hydroformylation of an olefinically-unsaturated compound with carbon monoxide and hydrogen to form one or more corresponding aldehyde products. The ligand is incapable of alkyl-aryl exchange, thereby leading to reduced ligand usage and improving ligand and transition metal, e.g., rhodium, recovery and recycling, as compared with prior art ligands.
