Patent ID: 6995292

Claim:
A method for reducing the fluoride content in a product of a chemical process, wherein said chemical process is selected from the group consisting of hydroformylation, hydrogenation, isomerization, hydrocyanation, hydrosilation, carbonylations, oxidations, acetoxylations, epoxidations, hydroamination, dihydroxylation, cyclopropanation, telomerizations, carbon hydrogen bond activation, olefin metathesis, olefin dimerizations, oligomerizations, olefin polymerizations, olefin-carbon monoxide copolymerizations, butadiene dimerization and oligomerization, butadiene polymerization, Heck reaction and arene coupling reaction, wherein said chemical process comprises reacting a reactant mixture in the presence of a catalyst comprising one or more transition metals selected from the group consisting of Group VIII metals and rhenium, and one or more fluorophosphite compounds having the general formula: wherein R 1 and R 2 are hydrocarbyl radicals which contain a total of up to about 40 carbon atoms and wherein the ratio of gram moles fluorophosphite ligand to gram atoms transition metal is at least 1:1, to produce a product containing fluoride, said method comprising contacting said product with an adsorbent to reduce the fluoride content in said product, wherein said adsorbent is selected from the group consisting of (a) oxides, carboxylates, hydroxides, bicarbonates, carbonates, phosphates, citrates, borates or ascorbates and mixtures thereof, and (b) calcium, sodium, magnesium, aluminum, zinc, silver, lithium, potassium, copper, cadmium, barium, silicon, talcites, hydrotalcites, molecular sieves, ion exchange resins, or mixtures thereof.
