Phosphorus-containing compositions and their use in hydrocyanation, isomerization and hydroformylation reactions
View Patent ↗A polymeric, phosphorus-containing composition made by heating, in the presence of an initiator, preferably a free radical initiator, and optionally in the presence of one or more comonomers, at least one substituted phosphonylated 2,2′-dihydroxyl-1,1′-binaphthalene or at least one substituted 2,2′-dihydroxyl-1,1′-biphenylene.
1. A method for making a polymeric, phosphorus-containing composition by heating, in the presence of an initiator, and, optionally in the presence of a Group VIII transition metal, a composition comprising at least one compound of Formula I and/or at least one compound of Formula II,
wherein:
x=0 to 4;
y=0 to 2;
a and b are individually either 0, 1, or 2, provided a+b=2;
each Ar is individually selected from the group consisting of phenyl, substituted phenyl, naphthyl, and substituted naphthyl, provided that the two Ar groups that are directly or indirectly bonded to the same phosphorus atom may be linked to each other by a linking unit selected from the group consisting of direct bond, alkylidene, secondary or tertiary amine, oxygen, sulfide, sulfone, and sulfoxide;
each Ar can be further substituted with C 1 to C 20 branched or straight chain alkyl, C 1 to C 20 cycloalkyl, C 6 to C 20 aryl, acetal, ketal, alkoxy, cycloalkoxy, aryloxy, formyl, ester, fluorine, chlorine, bromine, perhaloalkyl, hydrocarbylsulfinyl, hydrocarbylsulfonyl, hydrocarbylcarbonyl or cyclic ether;
each R is individually selected from the group consisting of hydrogen, ethenyl, propenyl, acryloyl, methacryloyl and an organic radical with a terminal ethenyl, propenyl, acryloyl, or methacryloyl group;
each R″ is individually selected from the group consisting of hydrogen, linear or branched alkyl, cycloalkyl, acetal, ketal, aryl, alkoxy, cycloalkoxy, aryloxy, formyl, ester, fluorine, chlorine, bromine, perhaloalkyl, hydrocarbylsulfinyl, hydrocarbylsulfonyl, hydrocarbylcarbonyl, cyclic ether, ethenyl, propenyl, and an organic radical with a terminal ethenyl or propenyl group;
provided at least one R represents ethenyl, propenyl, acryloyl, methacryloyl or the organic radical with a terminal ethenyl, propenyl, acryloyl, or methacryloyl group or at least one R″ represents ethenyl, propenyl, or the organic radical with a terminal ethenyl or propenyl group,
at atmospheric pressure and a temperature between 20° C. and 150° C. for 1 to 100 hours to produce the polymeric composition.
2. The method of claim 1 wherein the initiator is a free radical initiator.
3. A polymeric, phosphorus-containing composition made by the process of claim 1 .
