Identification of Some Chain Sulfides in a Wasson, Texas, Crude Oil Distillate Boiling from 111° to 150° C.

Identification of Thiaindans in Crude Oil by Gas-Liquid Chromatography, Desulfurization, and Spectral Techniques.

“…The presence in petroleum of thiols (1, S), chain sulfides (9), cyclic sulfides (1, 6, 10), thiophenes (1,11), and benzothiophenes ( 8) is well documented.…”

Spectrophotometric determination of primary aromatic amines with 9-chloroacridine

“…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 of Thiols in a Wasson, Texas, Crude Oil Distillate Boiling from 111° to 150° C.

“…of Wasson crude oil to produce a thiol concentrate (22.5 grams) and an aromatic, neutral-sulfur compound concentrate (445.2 grams) have been described previously (8,13). Both concentrates were investigated; however, the results from the thiol-free, neutral-sulfur compound concentrate, in which chain (13) and cyclic sulfides were identified, will not be discussed in this article. The thiol concentrate was vacuum fractionated, at a pressure of 450 mm.…”

“…Additionally, the development of a microdesulfurization method (14,16) has complemented the GLC technique, by providing a basis for identifications not possible otherwise. Recently, Thompson and coworkers (13), working with a 111°to 150°C. distillate from Wasson crude oil identified 22 chain sulfides of which six were reported earlier (15).…”
