(E3)-3-alkenyl methoxymethyl ether obtained by a coupling reaction between the 5-acetoxy-(E3)-3-pentenyl methoxymethyl ether and a Grignard reagent is treated with an acid, and then reacted with an acetylating agent to prepare the (E3)-3-alkenyl acetate. | 09-19-2013 |
20140123539 | Sustained Release Pheromone Formulation - A sustained release pheromone formulation is provided in which once it is secured to a branch or other support, the likelihood of falling off is significantly reduced, and which is capable of being quickly attached to a small or large branch. The sustained release pheromone formulation includes a first and second sheet parts which are provided by bending a single polymer sheet so that they are arranged in a face-to-face manner, the sheet parts each having an engaging hole therethrough; a bend part located between the sheet parts; at least one sex pheromone substance carried on at least a part of the sheet parts; and slits each extending from the bend part to the engaging hole in each one of the sheet parts. This formulation can be secured to the rod-shaped support by guiding the rod-shaped support to the engaging holes via the slits and engaging with the holes. | 05-08-2014 |
20140275656 | (Z,Z,E)-1-CHLORO-6,10,12-PENTADECATRIENE AND METHOD FOR PREPARING (Z,Z,E)-7,11,13-HEXADECATRIENAL BY USING SAME - Provided are (Z,Z,E)-1-chloro-6,10,12-pentadecatriene that can be synthesized without an oxidation reaction and a method for preparing (Z,Z,E)-7,11,13-hexadecatienal by using (Z,Z,E)-1-chloro-6,10,12-pentadecatriene while not using an oxidation reaction. More specifically, provided is a method for preparing (Z,Z,E)-7,11,13-hexadecatrienal including a step of reacting a Grignard reagent into which (Z,Z,E)-1-chloro-6,10,12-pentadecatriene is converted with ethyl orthoformate to obtain (Z,Z,E)-1,1-diethoxy-7,11,13-hexadecatriene, and a step of treating the (Z,Z,E)-1,1-diethoxy-7,11,13-hexadecatriene with an acid to obtain (Z,Z,E)-7,11,13-hexadecatrienal. | 09-18-2014 |
20140275657 | METHOD FOR PRODUCING CHLOROHYDROCARBON HAVING CONJUGATED DOUBLE BONDS - Provided is a method for producing a chlorohydrocarbon having conjugated double bonds by stereoselectively chlorinating an alcohol having conjugated double bonds. More specifically, provided is a method for producing a chlorohydrocarbon having conjugated double bonds, the method including a step of chlorinating an alcohol having conjugated double bonds with a chlorinating agent in a solvent in the presence of a base and in the absence of metal salt for chlorination of the alcohol, and the alcohol being represented by the formula (1): | 09-18-2014 |
