Aims: To develop an efficient protocol, which involves an elegant exploration of the catalytic potential of both the room temperature and surfactant ionic liquids towards the synthesis of biologically important derivatives of 2-aminothiazole. Objective: Specific heat capacity data as a function of temperature for the synthesized 2- aminothiazole derivatives has been advanced by exploring their thermal profiles. Method: The thermal gravimetry analysis and differential scanning calorimetry techniques are used systematically. Results: The present strategy could prove to be a useful general strategy for researchers working in the field of surfactants and surfactant based ionic liquids towards their exploration in organic synthesis. In addition to that, effect of electronic parameters on the melting temperature of the corresponding 2-aminothiazole has been demonstrated with the help of thermal analysis. Specific heat capacity data as a function of temperature for the synthesized 2-aminothiazole derivatives has also been reported. Conclusion: Melting behavior of the synthesized 2-aminothiazole derivatives is to be described on the basis of electronic effects with the help of thermal analysis. Additionally, the specific heat capacity data can be helpful to the chemists, those are engaged in chemical modelling as well as docking studies. Furthermore, the data also helps to determine valuable thermodynamic parameters such as entropy and enthalpy.

The peloids are the important natural remedy all over the world. Balneological and physical properties of eight Mongolian peloids collected from Lake Khyaraan (Selenge province), Tushigtsagaan (Selenge province) and Nogoon (Gobi-Altai province), Lake Kholboolj (Bayankhongor province), Lake Khundagan (Tuv province), Lake Tsaidam and Nokhoi Unadag (Arkhangai province), Lake Gurvan nuur (Khentii province), have been studied using analytical techniques. According the research we have determined physical properties of peloids from eight lakes (specific weight, moisture, porosity and moisture capacity) and balneological properties (liminess, thermal conductivity, heat capacity and the ability to retain heat) respectively. In result of the research, the physicochemical characteristics of the peloids are correcting standard satisfactory which treatment needs.
