Determination of the Carbon Skeleton and Other Structural Features of Organic Compounds by Gas Chromatography.

4,8-Dimethyldecanal: The Aggregation Pheromone of the Flour Beetles,Tribolium castaneumandT. confusum(Coleoptera: Tenebrionidae)

“…The retention times of pheromone and standard aldehydes with 5% SE-30 and 5% PEG-20M columns (3 mm x 2 m, 140°C, 1.2 kg/cm 2 ) were as follows: pheromone 4.S4 and 9.12 min, n-decana12.56 and 5.42 min, n-dodecanaI6.22 and 13.36 min, respectively.…”

Characterization of aggregation factors and associated compounds from the argentine ant,Iridomyrmex humilis

“…Microhydrogenolysis of compound A (10 ~ g) (cf. Beroza and Sarmiento, 1963) gave pentadecane as the major product, indicating an unbranched 16-carbon skeleton with a terminal oxygen function. Microhydrogenation (5 /~g) (cf.…”

Di-2-ethylhexyl phthalate in bovine heart muscle mitochondria: its detection, characterization, and specific localization.

“…Excess ozone resulted in the appearance of side products, and therefore the reaction was stopped as soon as the gas emerging from the reaction chamber contained ozone. The ozonized sample was subjected to gas The unknown compound was subjected to carbon skeleton chromatography (12,13 ing to the original sample in both retention time and peak area. The result again indicated the absence of aliphatic double bonds.…”
