Apparatus for Reaction Gas Chromatography. Instantaneous Hydrogenation of Unsaturated Esters, Alcohols, Ethers, Ketones, and Other Compound Types, and Determination of Their Separation Factors.

Sex Attractant Pheromone of the House Fly: Isolation, Identification and Synthesis

“…Configuration of the double bond was established as (a by TLC on silica gel-silver nitrate plates (14). Absence of branching was confirmed by instantaneous hydrogenation (15) of 100 pg of the olefin followed by combined GC-mass spectrometry of the saturated product (16); the mass spectrum matched that of n-tricosane.…”

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

“…Microhydrogenation (5 /~g) (cf. Beroza and Sarmiento, 1966) gave only one product of increased retention time (LRI 1790). The mass spectrum of this Product was indistinguishable from that of an authentic specimen of hexadecanal.…”

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

“…In order to get some idea of the number of double bonds present in the unknown compound about 2 ,ug was subjected to microhydrogenation as described by Beroza and Sarmiento (10) (Table 4). A tubular bypass splitter was used; the catalyst was "neutral" 1% palladium on 99% Gas Chrom P. Hydrogen was the obligatory carrier gas, while nitrogen was introduced into the port at the flame head where hydrogen usually enters in ordinary gas chromatography.…”
