摘要

"The process of obtaining sitofilate, feromu00c8nio of aggregation of the beetle Sitophilus granarius".The present invention relates to a process for obtaining the form of feromu00f3nio racu00eamica aggregation produced by the male beetle Sitophilus granarius, plague that attack stored grain.The feromu00f3nio racu00eamico is prepared in overall income greater than the methods described, using a process easy to reproduce from the acrylate 3 - etilpropila and propionaldeu00eddo.The first is easily prepared from acrylate, commercial and acrilou00edla pentan-3-ol commercial. The second obtained directly from commercial sources available in the Brazilian market.The catalysts used in the process and low cost have a low impact on the environment, it can be recovered.In this case the two centers estereoquu00edmicos of feromu00f3nio are generated during the synthesis.By providing a mixture of isomers readily separated by conventional chromatographic methods.The feromu00f3nio obtained, i.e., (2S, 3R) 3 - hydroxy - 2 - metilpentanoato 1 - etilpropila is a bioatraente substance, which can be used to control the infestation caused by Sitophilus granariuis.
