Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 139 words
A process for preparing metal organopolyphosphate coordination complexes comprising contacting a metal alkoxide selected from the group consisting of the aluminum, beryllium, magnesium, zinc, barium, gallium, indium, thallium, iron, tin and titanium alkoxides of (a) C 1-5 alkanols or haloalkanols; (b) glycol ethers of the formula ##STR2## where R 1 is independently each occurrence hydrogen, methyl, or halomethyl; R 2 is independently C 1-4 alkyl or phenyl, and n is a number from 1 to 5; and (c) C 1-10 alkanolamines of the formula R 3 -N-(Z) 2 where R 3 is C 1-10 hydroxyalkyl, and Z is each occurrence hydrogen, C 1-3 alkyl or hydroxyalkyl, with a slurry comprising a mixture of phosphorus pentoxide in an inert liquid organic medium in a ratio of alkoxy-functionality to phosphorus of 0.5:1 to 1:1, at a temperature less than 150° C.
Claim 2
Dependent Claim 139 words
A process for preparing metal organopolyphosphate coordination complexes comprising contacting a metal alkoxide selected from the group consisting of the aluminum, beryllium, magnesium, zinc, barium, gallium, indium, thallium, iron, tin and titanium alkoxides of (a) C 1-5 alkanols or haloalkanols; (b) glycol ethers of the formula ##STR2## where R 1 is independently each occurrence hydrogen, methyl, or halomethyl; R 2 is independently C 1-4 alkyl or phenyl, and n is a number from 1 to 5; and (c) C 1-10 alkanolamines of the formula R 3 -N-(Z) 2 where R 3 is C 1-10 hydroxyalkyl, and Z is each occurrence hydrogen, C 1-3 alkyl or hydroxyalkyl, with a slurry comprising a mixture of phosphorus pentoxide in an inert liquid organic medium in a ratio of alkoxy-functionality to phosphorus of 0.5:1 to 1:1, at a temperature less than 150° C.
Claim 3
Dependent Claim 13 words
The process of claim 1 wherein the metal organopolyphosphate coordination complex is recovered.
Claim 4
Dependent Claim 16 words
The process of claim 2 wherein the metal organopolyphosphate coordination complex is recovered by solvent removal.
Claim 5
Dependent Claim 17 words
The process of claim 1 wherein the inert liquid organic medium is CH 2 Cl 2 .
Claim 6
Dependent Claim 13 words
The process of claim 1 wherein the metal alkoxide is an aluminum alkoxide.
Claim 7
Dependent Claim 24 words
The process of claim 5 wherein the metal alkoxide is a metal alkoxide formed by reaction of aluminum triisopropoxide with four equivalents of butoxyethanol.
