“…It means that the micelle-like agglomerates influence the generation of the zeolite framework and serve as 'porogen' on the mesoscale in the hydrothermal reaction process. At the early aging stage, according to the previous work, the Gemini-9 surfactant aggregates are multilamellar vesicles micelles, [49] while the TPABr evenly distribute around the agglomerates of Gemini-9 surfactant due to the quite good solubility of the gemini surfactant in the solution. At the beginning of the hydrothermal reaction process, the aluminosilicate phase shaped with the involvement of the TPABr and Gemini-9 template on account of the combined action of phase separation behavior and the electrostatic interaction.…”

“…[44][45][46][47][48] In previous work, we reported a series of asymmetrical anionic-nonionic gemini surfactants. [49] Although, limited examples demonstrate the diversity of hierarchical ZSM-5 zeolites crystal morphologies achievable by gemini surfactants, no attempts to rationalize the role of gemini surfactants structure on the morphology of formed ZSM-5 nanocrystals have been reported yet. Herein, we report the series of anionic-nonionic gemini surfactants and tetrapropylammonium bromide (TPABr) templating route to synthesize hierarchical ZSM-5 zeolites.…”

An eco-friendly strategy for the synthesis of highly ordered meso-and microporous zeolites is required both in academia and industry. Therefore, asymmetrical anionic-nonionic gemini surfactants, polyoxyethylene laurinol ether sodium sulfoitaconate (Gemini-n), have been designed, synthesized and used in the directed synthesis of hierarchical ZSM-5 zeolites (HZSM-5) by imparting substantial mesoporosity. The hydrothermal temperature, the amount of gemini surfactants and the crystallization time strongly affected the crystallization degree and the textural properties of the HZSM-5. The tune of the porous size distribution (microporous to mesoporous) can be obtained by varying the number of the ethylene oxide units in the gemini surfactants. Besides, the use of these novel anionicnonionic gemini surfactants is an effective strategy to avoid phase-separation. The existence of abundant hydroxyl groups on the surface of HZSM-5 was used to immobilize molybdenum compound by the stable MoÀ O bond. The complex with abundant intercrystal mesopores exhibited superior catalytic performance with high yield and selectivity for the epoxidation reactions of alkenes as compared to the conventional ZSM-5. Moreover, the complex presented high catalytic ability after been reused for five times.

“…This indicates the presence of ester along with oxyethylene in C 16 ‐E2O2‐C 16 and the presence of oxygen atom (oxyethylene) along with carbonate in spacer part is substantially decreasing their CMC, in spite of their different charges. Similarly, PLSS‐n is showing comparable CMC (at room temperature) with the C 16 ‐E2O2‐C 16 gemini surfactant, although it is asymmetrical with two nonionic chains (the presence of oxyethylene along with ester group) and has other anionic sulfonate group in spacer (Li et al, 2019). This gives a new inference that –O–C=O group along with ether in a gemini surfactant can significantly reduce CMC (up to 10 −6 M), irrespective of the charge the gemini surfactant carries.…”

In this study, we prepared a novel series of diester-functionalized cationic gemini surfactants (C m-E2O2-C m) containing ethylene oxide as a spacer with varying alkyl chain lengths and characterized by 1 H NMR, FT-IR, elemental analysis, and ESI-MS. The physicochemical properties of the geminis were explored by tensiometry, fluorescence, dye solubilization, and Krafft point. These geminis acquire superior surface activity than the conventional surfactants. Fluorescence spectroscopy analysis affirmed that the micropolarity and aggregation number of micelles diminished with increase in the alkyl chain length. These geminis represent a new group of amphiphiles of considerably high biodegradability, better cleavability, and low toxicity as assessed by BOD test, FT-IR analysis, and HC 50 analysis, respectively. They also showed significant level of antimicrobial activity toward some specified bacterial strains of Gram-positive and Gram-negative by using agar well diffusion method. Furthermore, the thermogravimetric analysis provided information regarding thermal stabilities of the newly synthesized gemini surfactants.

“…Prasath and Ramakrishnan (2005) synthesized monododecyl itaconate and monocetyl itaconate and tested their application as polymerizable surfactants to prepare carboxylate functionalized polystyrene dispersions. Other applications of itaconic acid‐derived surfactants can be found in the literature, as gemini‐like foaming agents (P. Li et al, 2019) and as corrosion inhibitors (El Hefnawy et al, 2021).…”

This work reviews the use of carbohydrates and their derivatives as renewable raw materials in the production of surfactants. Methods to attain state‐of‐the‐art carbohydrate‐derived surfactants are described. This includes surfactants widely used nowadays and others that have not yet transcended beyond the academic field. Given the abundance of hydroxyl groups in carbohydrates and the considerable quantity of different surfactant structures that can be generated during their synthesis, selectively obtaining a target product represents a challenge. Therefore, this work focuses on the platform chemicals available to synthesize biobased surfactants. The first part of the review comprises a brief introduction of simple and complex carbohydrates to better understand their chemistry. Then, a description of the processes to obtain biobased building blocks derived from carbohydrates according to the National Renewable Energy Laboratory (NREL, USA), and their usefulness in synthesizing surfactants is presented. This provides an organized inventory of the knowledge around the synthesis–production of surfactants from carbohydrate derivatives, emphasizing raw materials that could be inserted into the circular bioeconomy concept. Finally, the current industry trends and the potential role of biobased surfactants around new dioxane regulations are discussed.
