The invention relates to the use of a gas or liquid-jet curtain generated by spraying non-flammable gases or liquids for diluting and/or ejecting clouds of flammable gases, the density of which does not exceed the density of air, from containments that have one or more outer openings, and also to a method for diluting and/or ejecting clouds of flammable gases, the density of which does not exceed the density of air, from containments that have one or more outer openings, wherein, by spraying non-flammable gases or liquids at at least one outer opening, a gas or liquid-jet curtain is generated that dilutes the clouds of flammable gases situated in the containment or bears them in the direction of the at least one outer opening and thus ejects them.

Method for diluting and/or ejecting clouds of flammable gases

A method of purifying an organic diphosphite of general formula (I)  The method comprises providing a crude organic diphosphite of general formula (I) that is at least partly dissolved in a first solvent (L1), wherein (L1) is selected from the group consisting of alkylbenzenes, aryl alkyl ethers, chlorobenzene, and mixtures thereof, and precipitating by admixing with a second solvent (L2) selected from the group consisting of linear C-C-alkanols, ethylene glycol di(C-C-alkyl) ethers, and mixtures thereof, and separating off the precipitated organic diphosphite from the solvents.

Method of purifying organic diphosphite compounds

The present invention relates to a process for preparing 6-chlorodibenzo[d,f][1,3,2]dioxaphosphepin (I) which comprises reacting 2,2'-dihydroxybiphenyl with PClin the presence of a catalytic amount of an acid salt of a nitrogen base, wherein the reaction is carried out in the absence of external organic solvents.

A description is given of a process for preparing solutions of radiation-sensitive, free-radically polymerizable organic compounds, where a first starting compound, which has an acid halide group, and a second starting compound, which has an alcoholic hydroxyl group, are esterified with one another in a solvent or in a solvent mixture. The solvent comprises one or more ketones having a boiling point of below 150&#xb0; C. under atmospheric pressure (1 bar), or the solvent mixture is composed to an extent of at least 50% by weight of said ketones. One of the two starting compounds has at least one radiation-sensitive group and the other of the two starting compounds has at least one ethylenically unsaturated, free-radically polymerizable group. A description is also given of corresponding solutions of radiation-sensitive, free-radically polymerizable organic compounds and of their use for preparing radiation-crosslinkable, free-radically copolymerized copolymers, more particularly for hotmelt pressure-sensitive adhesives or aqueous polymer dispersions.
