A process for preparing a phosphate ester which contains at least one terminal epoxide moiety, the process comprising contacting under reaction conditions, optionally in the presence of water, at least one phosphoric acid ester with an amount of an epoxide having an epoxy equivalent greater than one. The product compositions can be cured by standard epoxide curing agents to provide protective coatings having intumescent properties.

Epoxy phosphate compositions

Glycol ether partial esters of the formula ##STR1## where R is a specified substituent formed by reaction of monohydroxyl reactants of (poly)glycols with phosphorus pentoxide.

Partial esters of polyphosphoric acid

Derivatives of polyphosphoric acid partial esters of the formula ##STR1## wherein R is the remnant of a (poly)glycol monoether, phenol, or alkanol provided that in at least one occurrence R is the remnant of a (poly)glycol monoether, and M is a positive counterion of valence n are disclosed.

Derivatives of polyphosphoric acid partial esters

Derivatives of polyphosphoric acid partial esters of the formula ##STR1## wherein R is the remnant of a (poly)glycol monoether, phenol or alkanol provided that in at least one occurrence R is the remnant of a (poly)glycol monoether, and M is a positive counterion of valence n are disclosed.

Metal alkoxides are reacted with phosphorus pentoxide to produce metal organopolyphosphate coordination polymers.

Preparation of metal organopolyphosphate coordination of complexes

Cellulosic substrates, e.g., wood, textiles, or paper, have increased fire resistance when there are added thereto one or more compounds of the formula ##STR1## wherein M and R are specified substituents.

Fire-retardant composition containing derivatives of polyphosphoric acid

Quaternary ammonium phenates containing a 3-chloro-2-propenyl substituent group attached to the nitrogen atom and having as other substitutent groups attached to the nitrogen atoms (1) a C.sub.8 -C.sub.18 alkyl group, (2) a one carbon, two carbon, C.sub.8 -C.sub.18 alkyl or a 3-chloro-2-propenyl group, (3) a one carbon or two carbon alkyl or a 3-chloro-2-propenyl group, and (4) a phenate group, wherein not more than a total of two 3-chloro-2-propenyl groups are present in the molecule. The compounds have antibacterial and antifungal utility.

Quaternary ammonium phenates containing a (3-chloro-2-propenyl) group

Free flowing particulate pentachlorophenol having little or no tendency to bloom is obtained by incorporating about 0.5-10 percent by weight of benzyl alcohol. Prills made from molten pentachlorophenol containing the benzyl alcohol are a preferred form.
