Purification and Properties of Ten Organic Sulfur Compounds.

PHASE EQUILIBRIA IN FUSED SALT SYSTEMS: BINARY SYSTEMS OF PLUTONIUM(III) CHLORIDE WITH THE CHLORIDES OF MAGNESIUM, CALCIUM, STRONTIUM AND BARIUM1

“…Materials.-The sample of methanethiol was prepared at the Laramie Petroleum Research Center of the Bureau of Mines as part of American Petroleum Institute Research Project 48A. 5 The purity of this material was 99.94 ± 0.06 mole %, as determined by the time-temperature freez-…”

“…The uncertainty in the determination of coexe from the observed data has been discussed by Varshni and Shukla. 5 It appears that the reported value wexe = 4 is not satisfactory. A value of wexe -3 would be in accord with the considerations of references 3 and 5 and the present paper.…”

Physical properties of some sulfur and nitrogen compounds

“…EXPERIMENTAL Purification. Purification procedures were similar to those reported previously by this laboratory (4,5,6,8) on organic sulfur and nitrogen compounds. Three distillation columns were used: a column 30 cm.…”

“…'O SUPPLY fundamental data on the sulfur and nitrogen compounds that occur in petroleum, the Bureau of Mines prepared standard samples of organic sulfur and nitrogen compounds as reference materials and carried out intensive studies of their properties (4,5,6,8).…”

Application of DMSO in the Synthesis of 1,4-Disubstituted (But-1-en-3-ynyl)methylthioethers

“…The direct method for the synthesis of (but‐1‐en‐3‐ynyl)methylthioether derivatives is an addition of thiol or thiolate to 1,3‐diynes . However, there is no report about the reaction of 1,3‐diynes with methanthiol to prepare vinyl sulfides probably due to the hazardous of methanthiol (bp: 5.9 °C) . We envision that (but‐1‐en‐3‐ynyl)methylthioethers may be synthesized from the reaction of 1,3‐diynes with DMSO, which serves as a methylthiolating reagent.…”
