“…Knowledge of the physical and chemical properties of ILs is essentially important to optimize the use of ILs and design the desirable ILs. The speed of sound, u , is an important thermodynamic property that can be experimentally determined with great precision over a broad range of temperature and pressure, and it can be related with other thermodynamic properties such as density, heat capacity, thermal conductivity, and isentropic and isothermal compressibilities, which are essential for the accurate design and optimization of several industrial processes. The speed of sound is related to density, ρ and isentropic compressibility, κ S through Newton‐Laplace's equation

Speed of sound is an important thermodynamic property of ionic liquids (ILs) and always chosen as a source to determine other properties. A database for the speed of sound of pure ILs created by collecting experimental data from literature covering the period from 2005 to 2013 is presented. The effects of temperature and the alkyl chain length on the speed of sound are discussed and a second-order corresponding states group contribution method is developed to estimate the speed of sound. An average absolute deviation (AAD) of 2.34% has been obtained. This method offers a simple but reliable approach to estimate the speed of sound of new ILs. Finally, the speed of sound is used to determine the thermal conductivity of ILs based on the Bridgman theory. The calculated values of thermal conductivity show a good agreement with the experimental ones with an AAD of 3.91%.

“…Therefore, a rational function, which correlates 1/ c 2 as a function of the pressure and temperature by considering nine adjustable parameters, was used to correlate the experimental speeds of sound in liquid MeC10:0, MeC12:0, and MeC14:0, respectively, which is shown as follows: in which in eq , and the adjustable parameters A 0 – A 3 , B , C , D , E 1 , and F were listed in Table . This function was initially proposed by Daridon et al and improved by Queimada et al, which has been demonstrated to provide an adequate correlation of speed of sound data for n -alkanes ranging from ethane up to n -hexatriacontane with an average deviation of less than 1%. ,− …”

The speed of sound related with the isentropic bulk modulus has a significant effect on fuel injection and NO x emissions in diesel engines. Nevertheless, the speed of sound in pure fatty acid (methyl and ethyl) esters, which were widely used and investigated as the main components of biodiesel, is scarce in the literature. Most of the experimental data are available only at atmospheric pressure or in a narrow range of temperatures. In this work, the speed of sound in three fatty acid methyl esters [FAMEs = caprate (MeC10:0), laurate (MeC12:0), myristate (MeC14:0)] was measured by the Brillouin light scattering method. The measurements were carried out at temperatures ranging from 288 to 498 K along four isobaric lines of 0.1, 4.0, 7.0, and 10.0 MPa. The relative expanded uncertainty in the speed of sound was estimated to be less than 1.0%. A rational function that correlates 1/c 2 as a function of the pressure and temperature was used to correlate the experimental speed of sound in liquid MeC10:0, MeC12:0, and MeC14:0, respectively. In comparison of the experimental speed of sound to the correlation results in the measured range, the absolute average deviations (AADs) are 0.15% for MeC10:0, 0.10% for MeC12:0, and 0.17% for Mec14:0. Moreover, the data were also used to assess the predicted ability of Wada’s model.

“…In the literature surveyed on the bulk modulus of compressibility there are a number of models used by different authors to estimate the speed of sound in biodiesel. Nevertheless, only two models are commonly used an Example of these authors who have conducted experimental work include [505][506][507][508][509].…”

In the recent past, there has been a renewed shift into biomass and other recycled waste sources for biodiesel production and utilization. This is a critical area of research and study in which this present work intends to review and identify gaps in literature by shifting the focus of review to non-plant based sources for biodiesel production. Traditional biodiesel feedstock sources have always presented a conflict of food security versus energy. This shift will be identified in literature to see if change to non-plant-based feedstocks sources has increased food security by discouraging the contribution of commercial farming for the production of biodiesel. This work will identify biodiesel families, generations, traditional and non-traditional feedstocks for biodiesel production. It will also discuss the non-edible biodiesel feedstocks sources in relation to waste to energy recovery. The other factor this work will review is to study how the use of non-plant based feedstocks such as municipal solid waste has improved environmental protection by reducing pollution and landfilling. In other words, this work will review the impact of Using waste municipal solid biomass resources such as waste tyres and waste plastics and changing them into energy sources. This review study aims at increasing environmental awareness, sustainability and reporting the progress made in waste to energy policy shift in many countries globally. This review will look at socio-economic opportunities in recycling besides the academic and research impacts of waste to energy policies adopted in many countries. The review will climax with a conclusion and future trends in waste to energy in relation to municipal solid waste resources.
