The present invention relates to preparations having improved efficacy as flame retardants, to the use thereof and to polyurethanes containing the preparations according to the invention.

Preparations having improved efficacy as flame retardants

The present invention relates to phosphoric ester preparations with reduced hygroscopicity, to use of these as flame retardants and hydraulic fluids, and to polyurethanes which comprise the phosphoric ester preparations of the invention.

Phosphoric ester preparations with reduced hygroscopicity

The present invention relates to a process for continuous purification of yellow phosphorus by adsorption onto activated carbon.

Method for the purification of yellow phosphor

Flame retardant compositions for polyurethanes may include hydroxyl-containing poly(alkylene phosphates) that have 5 mol % or less of phosphorus from phosphorus-containing compounds having aP NMR resonance signal at a chemical shift in the range from 13 ppm to 18 ppm relative to 85 wt % phosphoric acid.

Hydroxyl-containing poly(alkylene phosphates)

The present invention relates to halogen-free oligomer mixtures of poly(alkylene phosphates), production of these and use as flame retardants, and also to flame-retardant polyurethanes comprising halogen-free oligomer mixtures as flame retardants.

Halogen-free poly(alkylene phosphates)

Low-scorch flame-retardant polyurethane foams include phosphorus-containing propionic ester flame retardants. Methods for producing and using the foams are also provided.

Low-scorch flame-retardant polyurethane foams

The present invention relates to a process for preparing tetraalkyl bisphosphates by reacting tetrachlorobisphosphates with alcohols, neutralizing the resultant hydrogen chloride with a base, and isolating the desired product from the reaction mixture by extraction.

Process for preparing alkyl phosphates

The present invention relates to wood-base materials made flame-retardant with halogen-free organic phosphorus compounds, and to compositions and processes for their production and their use.

Flame-retardant wood-based materials

The present invention relates to timber materials rendered flame-retardant by using halogen-free organophosphorus compounds, to means and processes for producing these materials, and also to their use.

Flame-retardant timber materials

The invention relates to fast-gelling plasticizer preparations comprising at least one aryl alkylsulfonate of the formula R&#x2014;SO&#x2014;O&#x2014;Rand at least one diol dibenzoate of the general formula RC(O)O&#x2014;Y&#x2014;O(O)CRand/or at least one dibenzyl dicarboxylate of the general formula RCHO(O)C&#x2014;Z&#x2014;C(O)OCHR, and also to its use as plasticizer in plastics, and to plastics which comprise these plasticizer preparations.

Fast-gelling plasticizer preparations

The present invention relates to plasticizer preparations based on triacetin with short gel time, and to their use, and to polyvinyl chloride preparations.

Plasticizer preparations

The present invention relates to novel low-monomer-content, low-viscosity preparations composed of isocyanurates which contain isocyanate groups and of phthalate-free plasticizers, to their use as adhesion promoters for coating compositions based on plasticized polyvinyl chloride, and also to coatings and to coated substrates.

Phthalate-free isocyanurate preparations

The present invention relates to fatliquoring agents for leathers, skins or hides, which contain neutral halogen-free organic phosphorus compounds, and the use of such fatliquoring agents for the flame-retardant treatment of leather and a process for fatliquoring in the production of flame-retardant leather, skin or hides.

Fatliquoring agents for the flame-retardant treatment of leather

Process for preparing dimethyl propanephosphonate, characterized in that dimethyl phosphite is reacted with propene in the presence of a free-radical former at a reaction temperature of 60 to 95&#xb0; C., the half life of the free-radical former being 0.1 to 20 min at the reaction temperature.
