Excess volumes of (N-methylmethanesulfonamide + an aliphatic alcohol)

Excess molar volumes and partial molar volumes for (propionitrile+an alkanol) at T=298.15 K and p=0.1 MPa

“…In spite of its fairly high dipole moment (3.50 AE 10 À30 C AE m) propionitrile is not a good proton acceptor [2]. Therefore, the addition of propionitrile, which is also a polar self-associated liquid, will result in the depolymerization of alkanol aggregates and hence an expansion in volume [18][19][20]. This effect becomes dominant as the chain length of the alkanol increases [17].…”

Effect of tri-potassium phosphate on volumetric, acoustic, and transport behaviour of aqueous solutions of 1-ethyl-3-methylimidazolium bromide at T=(298.15 to 318.15)K

“…The results of fitting experimental viscosity data to equations (14) and (15) are presented in table 7. Equation (14) was successfully used for fitting the viscosity values of many electrolyte solutions [43,45,46].…”

“…ILs can be designed for special applications because of the large range of cations and anions [3]. They are used in reaction rate enhancement, higher selectivities as well as higher yields and in the optimization of compound characteristics through a broad choice of anion and cation combination [14][15][16]. They can be used as solvents for synthetic purposes, separation technologies; as catalyst immobilizers for the easy recycling of homogeneous catalysts; as electrolytes in electrochemistry [17].…”

Modeling of Volumetric Properties of Organic Mixtures Based on Molecular Interactions

“…Also, the system with 2-methyl-2-propanol suggests that the steric hindrance of the tert-butyl group tends to hamper the complex less than with 2-butanol. This is a consequence of a predominating electrometric effect (+I effect) over steric effect in 2-methyl-2-propanol (Dharmaraju et al, 1981;Pikkarainen, 1982).…”
