Activity coefficients of sulfurous compounds in different extractants was written by Pais, M. A.;Bondarenko, M. F.;Abramovich, Z. I.;Kruglov, E. A.. And the article was included in Neftekhimiya in 1975.HPLC of Formula: 5339-69-5 This article mentions the following:
The activity coefficients of sulfur compounds such as cyclo- and dialkyl sulfides (I), mercaptans (II), and alkylthiophenes (III) in 10 extractants were determined by gas-liquid chromatog. The relative separation selectivities of the S compounds and hydrocarbons were calculated The separation selectivities decreased in the following order: III â?alkylbenzenes (IV) â?I > normal-paraffins > II. The activity coefficients of cyclic S compounds such as thiophane (V) and III varied with temperature increase in a manner similar to that shown by the corresponding IV in the same extractants. Thus, the activity coefficients of IV, V, and III increased in sulfolane [126-33-0] and tricresyl phosphate [1330-78-5] with increasing temperature In the experiment, the researchers used many compounds, for example, N-Isopropylbenzenesulfonamide (cas: 5339-69-5HPLC of Formula: 5339-69-5).
N-Isopropylbenzenesulfonamide (cas: 5339-69-5) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.HPLC of Formula: 5339-69-5
