WebFeb 24, 2024 · The organic phase initially contains M(TEHDGA) 2 (HEH[EHP]) 2 (NO 3) 3 complexes. As the ALSEP organic phase is scrubbed with an aqueous malonate buffer, the complex loses HNO 3 to form M(TEHDGA) 2 (H(EH[EHP]) 2 )(NO 3 ) 2 as the first organic-phase intermediate species. WebApr 27, 2024 · For example, viscosity of neat TEHDGA and TODGA at 303.00 K are 255.10 and 90.60 mPa s respectively, and a similar trend is seen at all the compositions . Lower values of density and viscosity of the TODGA compared to that of TEHDGA indicates that the inter-molecular interactions in TEHDGA are higher than that of TODGA.
