Abstract: A solvent-free curable composition has a long shelf life and consists of A 100 parts by weight of an epoxy resin and B from 10 to 100 parts by weight of, as a curing agent for the epoxy resin, an aromatic diamine containing groups, with or without C from 0.01 to 5 parts by weight of an accelerator, the curing agent for the epoxy resin being finely dispersed in the latter and preferably having a particle size of less than 10 mu m. The preferred epoxy resin curing agent is 4,4'-diaminodiphenyl ketone. The curable composition is used in particular for the preparation of fiber-reinforced materials.

Abstract: A process for the isolation of 4,4'-dichlorodiphenyl sulfone from a mixture of dichlorodiphenyl sulfones in which the ratios of the masses of 2,4'-dichlorodiphenyl sulfone and 3,4'-dichlorodiphenyl sulfone to the mass of 4,4'-dichlorodiphenyl sulfone are respectively from 0.5% to 20% and from 0.5% to 30% by treating the mixture with an alkanol at temperatures of from 20 DEG C. to 250 DEG C., cooling, and separating the pure 4,4'-dichlorodiphenyl sulfone that precipitates.

Abstract: PCT No. PCT/EP94/01684 Sec. 371 Date Aug. 11, 1995 Sec. 102(e) Date Aug. 11, 1995 PCT Filed May 26, 1994 PCT Pub. No. WO94/27950 PCT Pub. Date Dec. 8, 1994A mixture of (R)- and (S)-2-(4-alkanoylphenoxy)- or (R)- and (S)-2-(4-aroylphenoxy)propionic esters I I with an enantiomeric excess of at least 90% is prepared by reacting a mixture of (R) and (S) enantiomer of a 2-phenoxypropionic ester II II in which the appropriate (R) or (S) isomer is present in excess, with a carboxylic acid derivative of the formula III R1-CO-X III, (X=OH, halogen, R1COO or sulfonyloxy) in the presence of a Friedel-Crafts catalyst. The (R)- or (S)-2-(4-alkanoylphenoxy)propionic esters and (R)- or (S)-2-(4-hydroxyphenoxy)propionic esters are used for preparing crop protection agents and drugs.
