74-79-3, Name is L-Arginine, molecular formula is C6H14N4O2, HPLC of Formula: https://www.ambeed.com/products/74-79-3.html, belongs to amides-buliding-blocks compound, is a common compound. In a patnet, author is Zhang, Miao-Rong, once mentioned the new application about 74-79-3.
To understand the relationship between the structure and function of compounds for the extraction of Pd(II) from HCl solution, we investigated the Pd(II) extraction properties using three sulfide-containing diamides with the same N-substituents, N,NMODIFIER LETTER PRIME-dimethyl-N,NMODIFIER LETTER PRIME-diphenyl: thiodiglycolamide (mptdga), 3,3MODIFIER LETTER PRIME-thiodipropionamide (mptdpa), and 1,2-ethylene-bis(thioglycolamide) (mpebtga) diluted in chloroform. All of the diamides extract Pd(II) from 3.0 M HCl solution much faster than the conventional sulfide extractant, di-n-hexyl sulfide, and the extraction efficiency decreases in the order mpebtga > mptdpa > mptdga. The apparent stoichiometry of the Pd(II)-extractant complex extracted in the organic phase is 1:1 for mpebtga and 1:2 for mptdga and mptdpa. The FT-IR measurements show that the amide oxygen atoms in the diamides do not directly coordinate to Pd(II). These results indicate that the dominant complexes for the three diamides are [PdCl2(mptdga)(2)], [PdCl2(mptdpa)(2)], and [PdCl2(mpebtga)] with the sulfide coordinating to Pd(II).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 74-79-3 help many people in the next few years. HPLC of Formula: https://www.ambeed.com/products/74-79-3.html.
