“…It can be concluded that the α p of the pure ILs increases with temperature . From Figure , it can be observed that the highest thermal expansion coefficient has PIL with a 4-chlorobutyrate anion while with trichloroacetate and 3-chloropropionate anions, the thermal expansion coefficient is the lowest.…”

“…It can be concluded that the α p of the pure ILs increases with temperature. 21 From Figure 2, it can be observed that the highest thermal expansion coefficient has PIL with a 4chlorobutyrate anion while with trichloroacetate and 3chloropropionate anions, the thermal expansion coefficient is the lowest. The coefficient of thermal expansion describes how much the IL expands with the increase in temperature, and it is a good indicator of the strength of the interaction in the system.…”

In this work, previously prepared protic ionic liquids (PILs) with 1-ammonium-2-propanol cations and five different anions, acetate, trichloroacetate, chloroacetate, 3-chloropropionate, and 4-chlorobutyrate, and their aqueous solutions were characterized. Densities of ionic liquids (ILs) and their diluted aqueous solutions have been measured over the whole composition range at selected temperatures from T = 293.15 to 353.15 K for pure ILs and from T = 293.15 to 313.15 K for diluted aqueous solutions and at atmospheric pressure (p = 0.1 MPa). The influence of specific functional groups on the anion structure, density, volumetric properties, and the nature of interactions in aqueous solutions has been discussed. Several well-known techniques and criteria, such as volumetric quantities, Hepler's coefficient, or expansibility of the ions, were used to explain water structuring and the nature of interactions in the aqueous solutions of studied PILs and classify them as the structure-making (cosmotropes) or structure-breaking (chaotropes) substances.

“…The response to temperature change is expressed as the thermal expansion coefficient. The volumetric thermal expansion coefficient can be evaluated for all substances of condensed matter i.e liquids and solid state [23]. In other word, the thermal expansion coefficient represents the change in unit length per unit change in temperature [24].…”

The investigation of silicone rubber properties with the presence of platinum catalyst at different temperature using molecular dynamic simulation was conducted. Visual observation shows that structuring of silicone rubber occurs in the cell where the molecules aggregates closer compared to at the beginning of the simulation and at higher platinum concentration, silicone rubber molecules are more closely packed together. The diffusion coefficient of silicone rubber are the highest in a 10% platinum concentration followed by 25% and lastly 50% indicating that it is harder for the silicone rubber molecules to move from its original position in the system as the platinum concentration increases. Structural changes was also investigated through radial distribution function (RDF) where the position of peaks did not change with time but there is changes observed in the intensity of the peak. At a constant temperature 50°C, it was observed that the intensity of the peak at 1.10Å radius was the highest in the presence of 50%Pt followed by 25%Pt and 10%Pt. This indicates that higher numbers of silicone rubber molecules are present in a 1.10Å radius from the reference molecules in a system with higher concentration of platinum.
