“…Repeated readings on a series of different samples indicated good color stability for periods up to one week. Solutions of 9-chloroacridine must be prepared immediately before use because the acridine undergoes rapid ethanolysis in ethanol (5). Velocity constants of the nucleophilic replacement of the chlorine atom by ethoxide ion in 9-chloroacridine and other chloroheterocycles have been studied by Chapman and Russell-Hill (6).…”

“…ous butanol-ether mixtures (5), ethyl acetoacetate (6), ethyl acetate (7), butyl acetate (S), 2-methyl-l -propanol (9), 3-methyl-1-butanol (10), 1-butanol in chloroform (11), and 1-octanol (12). All of these were investigated and it was found that the most complete extraction, combined with the smallest extraction of interferences, and the smallest volume of organic reagent needed was obtained with 2-octanone, which has a very low solubility in water.…”

“…Identification through 1954 of 43 sulfur compounds in a Wasson, Texas, crude oil was reported by Thompson and coworkers (15). A related paper, (5), described the separation and identification of some sulfur compounds in a Wasson crude oil distillate boiling to 100°C. Since that date, the introduction of gas-liquid chromatographic (GLC) techniques has materially advanced the identification of sulfur compounds in petroleum.…”

Characterization of the naturally occurring sulfur compounds in petroleum is of both theoretical and practical interest to petroleum chemists and geologists. This paper describes a systematic procedure for the concentration and identification of 35 individual thiols present in a Wasson, Texas, crude oil distillate boiling from 111°to 150°C. The procedures applied included distillation, alumina adsorption, chemical extraction, gas-liquid chromatography, microdesulfurization, and infrared spectroscopy. Many Cs and Ce thiols, not commercially available, were synthesized, and GLC retention times and infrared spectra of some of these are presented. The procedures described represent a systematic method of sulfur compound analysis that should have general application in petroleum studies.

Sulfur-containing compounds in straight-run naphtha and catalytic-cracked gasoline were analyzed quantitatively using gas chromatography with a sulfur chemiluminescence detector. Pretreatment of the samples by open column chromatography and silver nitrate treatment were introduced to assign sulfur species. Commercial reagents, prepared standard samples and a commercial mass spectrum library were also utilized to assign the sulfur species. The sulfur content of naphtha was 242 ppm and 83 compounds were identified. Sulfur species consisted of 34 wt％ of thiacycloalkanes, 38 wt％ of thiols and sulfides, 12 wt％ of thiophenes, 11 wt％ of disulfides, and 5 wt％ of unknown compounds. The sulfur content of gasoline was 154 ppm and 41 compounds were assigned. Sulfur species consisted of 46 wt％ of thiophenes, 32 wt％ of benzothiophenes, 14 wt％ of thiols and sulfides, 4 wt％ of thiacycloalkanes, 0.6 wt％ of disulfides, 0.3 wt％ of hydrogen sulfide and 3 wt％ of unknown compounds. The combination of two types of pretreatment methods was effective for quantitative analysis of sulfur compounds contained in the distillate. The results of hydrodesulfurization of light distillate suggested that difficulty of hydrodesulfurization could be predicted from the composition of sulfur compounds in the distillates.
