Project summaryThe aim of the project is improvement of environment state in Kazakhstan agriculture. This will be achieved with usage of synthetic pheromones and attractants in order to forecast development of pest insects, determine terms for protective measures and to reduce significantly insecticide consumption. The following tasks should be done to achieve the aim:
– elaboration of modified copper supported catalysts and technology providing 100% yield of cis-olefins with ten time higher rate of hydrogenation;
– obtaining pheromones and attractants for pest insects on the basis of cis-olefins that are semiproducts of the said pheromones;
– conducting field tests of obtained pheromones and attractants to forecast development of pest insects and to establish the terms for protective measures.
Quantum chemical calculations and coordination approaches would be used for selection of modifiers for copper catalysts and technology. High pressure kinetic reactors would be used for hydrogenation.
During the project new selective catalysts (copper catalysts modified by rare earth metal oxides) for hydrogenation of acetylene derivatives into cis olefin compounds would be elaborated. New technologies for 100% selective hydrogenation of long chain derivatives (C16 - C22) into cis-olefins compounds (pheromones semiproducts and attractants) would be elaborated. Modified catalysts would be 10 times more effective than non-modified copper catalysts. On the basis of obtained cis-olefin compounds pheromones for clover worm-moth (pest insects for Lucerne, betroth, cabbage and other vegetables) and cotton worm-moth (pest insects for cotton and corn), attractants for gypsy moth, pest for trees). It is planned to conduct field tests of these pheromones and attractants for determination the exact terms of development of these pest insects for protective actions and significant reduction of insecticide consumption and for improvement of environment state.
