Molecular interaction mechanism of hydrogen bond disruption of highly viscous glycerol with aniline and derivatives analyzed with physicochemical data
Journal of Ultra Chemistry
Structural studies of highly viscous liquids are most attracting for several industrial significances. Hydrogen bonding and physicochemical properties (PCP) are critical probe for structural interactions. Thus density ( ± 10 -3 kg m -3 ), viscosity (± 10 -4 mPa.S), surface tension (γ ± 0.01 mNm -1 ) and friccohesity (± 10 -6 sm -1 ) for aniline (Anl) + glycerol (Grl) [AG], Anl + ethanol (Et) [AE], ortho-Anl + Et [OAE], para-Anl + Et [PAE] binary and Anl + Et + Grl [AEG], o-Anl + Et + Grl
... -Anl + Et + Grl [OAEG] and p-Anl + Et + Grl [PAEG] ternary mixtures for entire compositions are reported at 293.15 K. The Anl was soluble in Grl but the OA and PA were not soluble, thereby, the Et was added to solubilize them and noted as interlocutoror hydrogen bond disruptor. The , η, and were regressed with the Grl mole fractions (x G ) for their 0 , η 0 , 0 and 0 limiting data with S , S , S and S slope values. The 0 as Grl > AEG >AG > PAEG > OAEG inferred stronger interactions with AEG and AG while the weaker with OAEG. The 0 as AEG >AG > OAEG > PAEG inferred hydrogen bonding (HB) disruption respectively as compared to Grl and decreases the resistance to flow. Their 0 as Grl >AEG >AG > OAEG > PAEG weakened 21.60, 33.40, 71.32 and 76.10% cohesive forces (CF) respectively and quantitatively the CF was demonstrated with proposed Spring-Weight (SW) model.
