标题:Identification And Synthesis Of The Male-Produced Sex Pheromone Of The Soldier Beetlechauliognathus Fallax(Coleoptera: Cantharidae)
摘要:Chauliognathus Fallax Germar 1824 (Coleoptera: Cantharidae) occurs In North And South America And Australia. Gas Chromatographic (Gc) Analyses Of Volatiles Released By Adults Showed The Presence Of A Male Specific Compound. Gc Coupled With Electroantennographic Detection (Gc-Ead) Showed That This Compound Is Exclusively Bioactive On Female Antennae,Suggesting It To Be A Sex Pheromone. Gc Coupled With Mass Spectrometry (Gc-Ms) And Fourier Transform Infrared Spectroscopy (Gc-Ftir),As Well As Dimethyl Disulfide (Dmds) Derivatization And Hydrogenation,Suggested The Target Compound To Be (Z)-Tricos-11-Ene. Unambiguous Structural Proof Was Achieved By Independent Synthesis,Whereas The Biological Significance Of The Compound As A Sex Pheromone Was Confirmed By Field Bioassays.

摘要:The present invention provides intermediates for the synthesis of 1,2-bis(4,7-dimethyl-1,4,7-triazacyclonon-1-yl)-ethane and preparation method thereof. The intermediates are protonated salts of 1,4-ditosylate-1,4,7-triazacyclononane or 1,4-dibenzenesulphonate-1,4,7-triazacyclononane. The preparation method of 1,4-diarylsulfonate-1,4,7-triazacyclononane (compound A) comprises reacting 1,4,7-triarylsulfonate-1,4,7-triazacyclononane (compound B) in an acidic medium comprising sulphuric acid, wherein the molar ratio of B to sulphuric acid is in the range from 1 : 0.5 to 1 : 10, or reacting 1,4,7-triarylsulfonate-1,4,7-triazacyclononane (compound B) in an acidic medium and working up the acidic medium when the conversion of B to A is at least 50 mol % yielding compound A.

摘要:The present invention relates to a method of forming iron oxide nanoparticles comprising the steps of (a) suspending iron oxide/hydroxide and oleic acid or a derivative thereof in a primary organic solvent; (b) increasing the temperature of the suspension by a defined rate up to a maximum of 340° C. to 500° C.; (c) aging the suspension at the maximum temperature of step (b) for about 0.5 to 6 h; (d) cooling the suspension; (e) adding a secondary organic solvent; (f) precipitating nanoparticles by adding a non-solvent and removing excess solvent; (g) dispersing said nanoparticles in said secondary organic solvent; (h) mixing the dispersion of step (g) with a solution of a polymer; and (i) optionally removing said secondary organic solvent. The present invention further relates to an iron oxide nanoparticle obtainable by the method, the additional modification, encapsulation and decoration of such nanoparticles, as well as the use of the nanoparticles as tracers for Magnetic Particle Imaging (MPI), Magnetic Particle Spectroscopy (MPS).

标题:Reclamation of bisphenol tars as feedstock in the synthesis of aminophenylhydroxphenylalkanes
发明人：LIKIBI PARFAIT J M
权利人:GEN ELECTRIC
摘要:The disclosure is of a process for recovering valuable by-products of the condensation of phenol and a ketone from a mother liquor obtained for example upon crystallization of a 1:1 adduct of phenol and bisphenol, said mother liquor containing phenol, bisphenol, isomers, contaminant by-products of the condensation reaction of phenol with the ketone and acidic impurities. The mother liquor is distilled/evaporated leaving a tarry residue, which is the feedstock for the process of the invention. The recovery comprises heating the feedstock with proportions of an arylamine salt, to extract the bisphenol-A values as aminophenylhydroxylphenyl-alkanes.
