The present invention discloses nitromethylene derivatives and the uses thereof. These derivatives are obtained by adding ring structure onto the known nitromethylene compounds, by which both their stability for light and their liposolubility are increased. Furthermore, by using the substituents linked to ether bond, the steric orientation of the nitro group and the liposolubility of the compounds are controlled. The insecticidal activity tests show that the compounds and their derivatives of the invention display high efficiency on killing various destructive insects with piercing-sucking type or scratching type mouthparts, such as aphid, leafhopper, plant hpooer, thrips and white fly.

Die vorliegende Erfindung betrifft die Verwendung eines Amins der Formel (I) als Bestandteil eines Härters für Epoxidharze, Härter für Epoxidharze enthaltend das Amin der Formel (I) und damit erhaltene Epoxidharz-Zusammensetzungen, welche insbesondere als emissionsarme raumtemperaturhärtende Epoxidharz-Beschichtungen mit hoher Härte und Oberflächenqualität verwendbar sind. Das Amin der Formel (I) ist geruchsarm und verdünnt EpoxidharzZusammensetzungen sehr gut. Es wird insbesondere mittels reduktiver Alkylierung aus 1,2-Ethylendiamin oder 1,2-Propylendiamin und einem Aldehyd oder Keton erhalten.
The use of an amine of formula (I) as a component of a hardener for epoxy resins, hardeners for epoxy resins containing the amine of formula (I), and resultant epoxy resin compositions which can particularly be used as low-emission room-temperature-curing epoxy-resin coatings with high hardness and surface quality. The amine of formula (I) is low-odour and a very successful diluent for epoxy resin compositions. It is particularly obtained by reductive alkylation from 1,2-ethylenediamine or 1,2-propylenediamine and an aldehyde or ketone.
