HARDENER AND CURE ACCELERANT WITH FLAME RETARDANCY EFFECT FOR CURING EPOXY RESINS (II)

The present invention relates to novel hardeners for curing epoxy resins and to cure accelerants for the accelerated curing of epoxy resins comprising, in each case, at least one compound from the group of esters of phosphorus-containing acids according to Formula (I), wherein there applies to Formula (I): wherein there applies to the radicals R1, R2, R3, R6, X and indices m, n, p, simultaneously or independently of one another: R1, R2=simultaneously or independently of one another, hydrogen or alkyl, R3=alkyl, aryl, —O-alkyl, —O-aryl, —O-alkylaryl or —O-arylalkyl,R6=hydrogen, alkyl or —NHC(O)NR1R2,X=oxygen or sulphur,m=1, 2 or 3,n=0, 1 or 2, wherein there applies: m+n=3p=0, 1 or 2.

Transformation of fenuron induced by photochemical excitation of humic acids

When neutral solutions containing the herbicide 3-phenyl-1,1-dimethylurea (fenuron) and-a humic acid are irradiated at 365 nm, 3-(4-hydroxyphenyl)-1,1-dimethylurea and three biphenyl products are formed as main products. The apparent quantum yield of fenuron disappearance is evaluated as 6-2 x KT'moleE-1. Upon irradiation of the same mixture at 253-7 nm, both direct and induced phototransformations of fenuron occur. Direct photooxidation yields 2- and 4amino-N,AT-dimethylbenzamide. The induced phototransformation leads to 2and 4-hydroxylation of the aromatic ring in accordance with the fact that hydroxyl radicals are involved in the oxidation.
