“…Therefore, it is considered as a new generation of ionic liquids or their substitutes. 11 DESs are immiscible with esters, but miscible with water. Therefore, they can be easily separated from the lower layer of the esterification reaction system and reused after simple treatment, which will greatly reduce the energy consumption of separation process.…”

In this work, the optimum process conditions and kinetics of the green synthesis of isobutyl cinnamate using deep eutectic solvents (DESs) as catalysts were investigated. Isobutyl cinnamate is a spice with low toxicity and is widely used in the food industry. However, there is a lack of reports on its green synthesis. Three DESs were prepared by adjusting the mixing ratio of choline chloride (ChCl) and p‐toluenesulfonic acid (PTSA). Response surface methodology with Box‐Behnken design (RSM‐BBD) was used to optimize the process parameters of the esterification of cinnamic acid with isobutanol. The effects of catalyst loading, stirring speed, cinnamic acid/isobutanol molar ratio, and temperature on the conversion of cinnamic acid over time were evaluated. Using ChCl‐PTSA as a catalyst, the kinetics data and chemical equilibrium constants of the esterification were determined at a temperature range of 353.15–383.15 K. The pseudo‐homogeneous (PH) model based on activity was then adopted to describe the kinetics of the reaction, and the relative deviations between the experimental values and the calculated ones by PH model are less than 5.5%. Thermodynamic data (ΔrH0, ΔrS0, ΔrG0) for the esterification reaction was calculated as well. In addition, the results of six consecutive cycles of the catalyst showed that ChCl‐PTSA has good stability and recyclability.

The composition, thermal properties, and microstructure of some mutton tallows (MTs), such as sheep tallow (ST), goat tallow (GT), and sheep tail tallow (STT), were investigated and compared with those of beef tallow (BT). The results showed that the fatty acids (FAs) in the MTs were dominated by oleic, stearic, and palmitic acids, which were similar to those of BTs; also there were some natural trans and odd‐carbon FAs occurred in these tallows. Comparison with STs, GTs, and BTs, STT had higher triunsaturated and diunsaturated‐monosaturated triacylglycerols (TAGs) and lower monounsaturated‐disaturated and trisaturated TAGs. Solid fat content (SFC) profile of STT was different those of STs, GTs, and BTs, whereas STs, GTs, and BTs had similar SFC profiles. In the range of 0–50°C, STT had a lower SFC compared with STs, GTs, and BTs at a given temperature. DSC results showed that MTs had melting and crystallization curves similar to BTs; and the GT, ST, and BT had higher melting and crystallization temperatures than STT. All MT and BTs crystals are β′ form; there also exists certain β form. The microscopic morphology of the STT was radial spherical aggregates, and those of other MT and BTs were consisted of radial inner core and low density outer halo area.Practical Application: The results of SFC, microstructure, and morphology indicated mutton tallows containing the desired crystal form and crystal morphology could be used as shortening base fats. The research can provide a theoretical basis for expanding the application of mutton tallows in food industry.
