The surface of said metal flake is preferably coated with a phosphorous compound.

The fire retardant contains at least a phosphorous compound having an amide bond.

The molar ratio of the phosphorous compound to the dye is 0.5 or higher.

In some examples, the phosphorated compound comprises an average particle size less than 10 microns.

The porous semiconductor layer contains a dye and decylphosphonic acid or another phosphorous compound.

In other examples, the phosphorated compound provides a surface area of 78.5 μm2 to about 1965 μm2.

A catalyst and method of forming a catalyst for use in aromatic alkylation involves treating a zeolite, which may be a ZSM-5 zeolite, with a phosphorus- containing compound.

They may also include providing hydrogen and one or more phosphorous compounds to the microorganisms.

Improved flame retardant polytrimethylene terephthalate compositions are provided by including a certain phosphorous compound as a flame retardant additive.

Disclosed is an additive composition for lubricants, which can be prepared easily and is composed of a phosphorus-containing compound metal salt.

The proportion of phosphorous compound is 5-35 wt % of the total weight i.e. of the polyamide mixture.

Specifically, after melting a mixture that contains (A) a polybutylene terephthalate resin and (B) a polyvalent hydroxyl group-containing compound, (C) a phosphorus compound is added thereto.

In certain examples, the compositions comprise a halogen-free or substantially halogen-free epoxide and one or more phosphorated compounds.

Said additive compound DOP supplies up to 3.5 mass % of a total phosphorus content whereas the rest of the total phosphorus content is supplied by the other bifunctional phosphorous compound.

A method of treating a ZSM-5-type zeolite catalyst is carried out by treating a ZSM-5 zeolite catalyst having a silica/alumina mole ratio of at least about 200 with a phosphorus compound.
