Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Chemical and Pharmaceutical Research called Solvent extraction of palladium(II) with 2-hexyl-5-methyl benziminazole sulfide, Author is Liu, Yan; Huang, Zhangjie; Chen, Muhan; Chen, Lei, which mentions a compound: 27231-36-3, SMILESS is SC1=NC2=CC(C)=CC=C2N1, Molecular C8H8N2S, Related Products of 27231-36-3.
A new extractant of 2-hexyl-5-Me benziminazole sulfide (HMBMS) was synthesized and used in the extraction of Pd(II) from hydrochloric acid solution Pd(II) was extracted quant. with HMBMS in kerosene. Thiourea solution could be used as stripping agent. Extraction parameters of Pd(II), including 2-hexyl-5-Me benziminazole sulfide (HMBMS) concentration, contact time of aqueous and organic phases, organic/aqueous (O/A) phase ratio and hydrochloric acid concentration of aqueous phase, were studied in detail. The extraction saturation capacity of Pd(II) was determined from 0.1mol L-1 HCl solution with 30% (volume/volume) HMBMS and its exptl. value exceeded 10 g L-1 under the exptl. conditions. Pd(II) and Pt(IV) could be separated effectively and the separation coefficient of Pd(II) and Pt(IV) (ssPd/Pt) reached 1.5×104 when HMBMS and HC1 concentration were fixed at 20% (V/V) and 0.1 mol L-1, resp. Stripping of Pd(II) from loaded organic phase was performed using thiourea solution
Different reactions of this compound(2-Mercapto-5-methylbenzimidazole)Related Products of 27231-36-3 require different conditions, so the reaction conditions are very important.
