Research Progress on the Synthesis of Different Types of Gemini Surfactants with a Functionalized Hydrophobic Moiety and Spacer Yumnam Gyani Devi, Ajmal Koya Pulikkal, Jackson Gurung Chemistryselect, 2022 Abstract Gemini surfactants are advantageous over conventional surfactants as they find applications as antimicrobial agents, corrosion inhibitors, enhanced oil recovery, capping agents for nanoparticle synthesis, drug delivery agents, etc. This article provides a detailed overview of synthetic procedures for various types of geminis and the fundamental physicochemical parameters of these systems. This includes a discussion on the cationic geminis based on various groups such as biphenyl, amide (with/without alkane tail), binol, quaternary ammonium (with/without hydroxyl group as a spacer), morpholinium, pyridinium, amide (with/without alkane tail), ester quaternary ammonium, and imidazolium (spacer with/without hydroxyl group and thioether/ester) types. Further, it is focused on anionic geminis with carboxylate, borate, and sulfonate head groups. Zwitterionic geminis such as betaine surfactants, cocogem surfactants based on dodecylisopropylol amine and dicarboxylic acid, diester type, sulphobetaine gemini based on S‐triazine, zwitterionic hetero gemini containing ammonium and carboxylate head groups, zwitterionic gemini containing quaternary ammonium and a sulfate group, gemini containing phosphodiester anion and quaternary ammonium salt are also reviewed. Lastly, synthesis of nonionic geminis from sunflower oil, amide‐based nonionic, sulfonamide nonionic, N , N’ ‐diethylaminedialkyldiamide nonionic gemini, sugar‐based gemini, and nonionic gemini with sulfonate spacer have been discussed.
Optimizing pyrolysis process parameters of plastic grocery bag, with mass–energy assessment and characterization of oil at optimal condition Dipankar Saha, Jackson Gurung, Bidesh Roy, Ajmal Koya Pulikkal, Abhijit Bhowmik, Satyajit Pattanayak Clean Technologies and Environmental Policy, 2022 The widespread usage of plastic grocery bags, as well as their non-biodegradability, has turned out to be a stern reason for waste generation. With regard to plastic grocery bag disposal, pyrolysis is an encouraging solution that addresses the energy crisis issue as well. This study examined the interactive influences of pyrolysis temperature, residence time, and nitrogen flow for plastic grocery bag pyrolysis to optimize waste plastic oil yield by the Grey–Fuzzy–Taguchi method. Additionally, mass–energy assessment and characterization were done for the waste plastic oil, extracted at the optimal parametric condition. The optimal parametric combination was: temperature 400 °C, time 360 min, and nitrogen flow rate 20 ml/min. The liquid yield at optimal condition was 78.57%, and a minimal error (2.53%) between the predicted and experimental grey fuzzy grade was observed. The oil achieved at optimal condition showed a high hydrocarbon content with a higher heating value of 46,685 kJ/kg. The values of mass ratio, energy ratio, energy efficiency, and energy consumption ratio for the liquid oil were 0.79, 0.89, 0.63, and 0.47, respectively, which indicate the energy favorability for plastic grocery bag pyrolysis. FT-IR results demonstrated mainly the existence of alkene and alkane functional groups in the waste plastic oil. GC–MS results revealed that the oil contains mainly light and middle fractions of 26.4% and 62.7%, respectively, with a smaller proportion (10.9%) of heavy fraction. Finally, the optimum parametric combination can be considered a useful condition for extracting quality fuel from plastic grocery bags.
