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.
