The volatiles of live male Mamestra oleracea populations were observed to contain main pheromone components Z11-hexadecenyl acetate, Z9-hexadecenyl acetate, Z11-hexadecenol and various amounts of minor components in each population. In field experiments in 3 regions there were active mixtures of Z11-hexadecenyl acetate, Z11-hexadecenol and Z11-tetradecenol in various levels and ratios.

Kaur, Inderjeet published the artcileLiving radical polymerization and grafting of diethyl (acryloyloxy) ethylthiophosphoramidate onto cotton fabric to impart flame retardancy, SDS of cas: 3052-61-7, the publication is Surface and Coatings Technology (2010), 205(7), 2082-2090, database is CAplus.

A novel phosphorus, nitrogen and sulfur containing monomer, di-Et (acryloyloxy) ethylthiophosphoramidate was synthesized in a two step reaction. The monomer was polymerized and grafted onto cotton fabric by the living radical polymerization method using benzyl N,N-di-Et thiocarbamate as iniferter and sur-iniferter resp. The monomer, its precursor, iniferter and the polymer were characterized by spectroscopic techniques. Flame retardant property of the modified cotton fabric was studied by the Shirley Manual Flammability Tester and it was found that the incorporation of phosphorus and nitrogen together exerts a synergistic effect in imparting flame retarding property to the fabric.

Heath, R. R. published the artcileCorrelation of retention times on liquid crystal capillary column with reported vapor pressures and half-lives of compounds used in pheromone formulations, Product Details of C14H26O2, the publication is Journal of Chemical Ecology (1986), 12(11), 2081-8, database is CAplus and MEDLINE.

A method was developed to determine by capillary gas chromatog. on liquid crystal stationary phases the relative vapor pressures and half-lives of many compounds used as insect pheromones. The retention time of 7 acetates on a liquid crystal column (cholesteryl-p-chlorocinnamate) was correlated closely to the reported vapor pressures of the compounds For 13 addnl. pheromonal acetates and alcs., reported half-lives showed a high degree of correlation with their retention times on the liquid crystal column. Thus, chromatog. on capillary liquid crystal gas chromatog. columns is a useful method for determining the relative volatiles of many pheromones to facilitate the development of more precise formulations.

Dix, M. E. published the artcileSex pheromone of Retinia metallica (Busck) (Lepidoptera: Tortricidae): identification and field studies, COA of Formula: C14H26O2, the publication is Canadian Entomologist (1988), 120(8-9), 721-6, database is CAplus.

The major sex pheromone component from female moths of R. metallica was identified as Z7,E9-dodecadienyl acetate (Z7,E9:Ac) by a combination of electroantennog. (EAG), gas chromatog. (GC), and mass spectrometric analyses. In field tests, males of R. metallica were strongly attracted to Z7,E9-12:Ac. Addition of Z7,Z9-12:Ac, Z7,E9-dodecadienol (Z7,E9-12:OH), and Z7-dodecenyl acetate (Z7-12:Ac) to Z7,E9-12:Ac did not significantly alter trap catch. However, the addition of E9-dodecenyl acetate (E9-12:Ac) and Z9-12:Ac reduced trap catch. Trap catch was affected by height of placement; traps placed in the upper third of the tree (6 m) caught significantly more males than traps placed at lower heights.

Palaniswamy, P. published the artcileMechanisms of orientation disruption by sex pheromone components in the redbacked cutworm, Euxoa ochrogaster (Guenee) (Lepidoptera: Noctuidae), Application of (Z)-Dodec-9-en-1-yl acetate, the publication is Environmental Entomology (1988), 17(3), 432-41, database is CAplus.

Disruption of orientation of E. ochrogaster males to synthetic bait was studied in a flight tunnel and in small field plots in cereals, using synthetic pheromone components as disruptants. Field tests showed that increasing the dose from 0 to 100 μg per dispenser of the blend of all 4 components (Z)-5-dodecenyl acetate (Z5-12:Ac) + (Z)-7-dodecenyl acetate (Z7-12:Ac) + (Z)-9-dodecenyl acetate (Z9-12:Ac) + (Z)-5-decenyl acetate (Z5-10:Ac) or that of Z5-12:Ac and Z7-12:Ac, individually, resulted in a sharp increase in disruption up to a maximum of 75%; a further increase in the dose to 1000 μg per dispenser resulted in only a small and gradual increase in disruption, reaching a maximum of 88%. Z5-10:Ac caused approx. 78% disruption at levels of 100 μg and 1,000 μg per dispenser, and Z9-12:Ac was least effective at these doses. Flight tunnel and field observations showed that with blends, the mechanisms of disruption varied in relation to the concentrations used. The primary cause of disruption was competitive attraction at low dose levels and reduction in searching effort at high dose levels. With single components, irresp. of concentrations used, the cause of disruption was primarily reduction in searching effort. Based on these studies and those on Euxoa messoria and Malacosoma disstria, it is suggested that in moths, depending upon the species, functional nature of the pheromone components, concentrations used, and the method of disruptant dispenser placements, individual or blends of components can cause orientation disruption by competitive attraction and by modulating the behavior of males, particularly by reducing the searching effort.

Palaniswamy, P. published the artcileResponses of male redbacked cutworm, Euxoa ochrogaster (Lepidoptera:Noctuidae), to sex pheromone components in a flight tunnel, Formula: C14H26O2, the publication is Environmental Entomology (1983), 12(3), 748-52, database is CAplus.

Of 4 components of the title pheromone, individually only Z5-12:Ac ((Z)-5-dodecenyl acetate; I) [16676-96-3] and Z7-12:Ac ((Z)-5-dodecenyl acetate; II) [14959-86-5] stimulated activation responses of the E. ochrogaster males, but neither initiated upwind flight in the flight tunnel. Of all possible binary combinations only I + II elicited responses from activation to landing. Z5-10:Ac ((Z)-5-decenyl acetate) [67446-07-5] increased activation, upwind flight responses, and prolonged flight, but only when it was added to blends containing I + II. Addition of Z9-12:Ac((Z)-9-dodecyl acetate) [16974-11-1] as a 4th component increased initiation of landing response on the source. In moth pheromone systems utilizing several components, the sequence of male responses in locating and mating with a female depends upon specific combination of pheromone components and concentrations

Hattori, Hideshi published the artcileSynthesis and properties of photochromic liquid-crystalline polyacrylates containing a spirooxazine group, SDS of cas: 50670-76-3, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (1999), 37(17), 3513-3522, database is CAplus.

The novel photochromic liquid-crystalline polyacrylates containing a spirooxazine group were synthesized. The photochromic polymer containing (4-pentamethyleneoxy)biphenylene moiety at the 5-position of spironaphthoxazine showed nematic phase from 122.9 to 133.8°C. The photochromic polymer containing undecamethylene instead of pentamethylene showed smectic phase from 93.1 to 169.7°. On the other hand, the photochromic polymer containing both undecamethylene as a spacer and spironaphthoxazine-bound biphenylene moiety at 9′-position did not show any liquid crystallinity. All spirooxazine-containing liquid-crystalline polymers showed photochromism in the solid state at room temperature Because the shape of the absorption spectra of the photochromic quenched liquid-crystalline polymer films was almost the same as those of the photochromic amorphous polymer films, the photochromic properties did not depend on the mesophase in the polymers examined

Novel polymerizable photochromic liquid crystal materials containing either the 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]naphth[2,1-b][1,4]oxazine] group or the 1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3′-[3H]pyrido[3,2-f][1,4]benzoxazine] group as the photochromic moiety, and the biphenylene unit as the mesogenic moiety, were synthesized. Thermal and phys. properties of the compounds were examined using DSC, optical polarizing microscopy, wide-angle x-ray diffractometry and UV-visible spectrophotometry. The photochromic compounds containing both photochromic and mesogenic moieties showed metastable mesophases; these tended to crystallize with time and on heating. The crystallization behaviors were strongly dependent on the structure of the terminal group of alkylene spacer and the position of the spiro-oxazine bound to the mesogen.
