Abstract
Official abstract text for this publication.
Disclosed herein are flame retardant materials, and in particular materials and processes for phosphorylating materials for flame retardant applications
First claim
Opening claim text (preview).
1 . A method for producing flame retardant additives, comprising phosphorylating a carbon-containing material to thereby produce a flame retardant additive. 2 . The method of claim 1 , further comprising phosphorylating the carbon-containing material to increase char formation. 3 . The method of claim 2 , the carbon-containing material is lignin. 4 . The method of claim 2 , the carbon-containing material is tannin. 5 . The method of claim 2 , the starting material is tannic acid. 6 . The method of claim 2 , the carbon-containing material is oil. 7 . The method of claim 2 , the carbon-containing material is hydroxylated linseed oil. 8 . The method of claim 2 , the carbon-containing material is cottonseed oil. 9 . A phosphorylated product, prepared by a process comprising the step of phosphorylating a carbon-containing material. 10 . The method of claim 9 , the carbon-containing material is lignin. 11 . The method of claim 9 , the carbon-containing material is tannin. 12 . A flame retardant, comprising: phosphorous; and a carbon-containing compound, wherein the carbon-containing compound is phosphorylated to increase char formation. 13 . The flame retardant of claim 12 , wherein the carbon-containing compound comprises oil. 14 . The flame retardant of claim 12 , wherein the carbon-containing compound comprises tannin. 15 . The flame retardant of claim 12 , wherein the carbon-containing compound comprises lignin. 16 . The flame retardant of claim 15 , wherein the lignin is a phosphorylated lignin.
