“…Figure S9 compares the contact angles of SBLD and BOS. The results showed that the contact angle of the BOS aqueous solution is lower (40 ) than that of the SBLD aqueous solution (70 ). Consequently, the wettability of the BOS aqueous solution is better than that of the SBLD aqueous solution which may be attributed to the unique branched-chain structure of BOS.…”

A new series of bio‐based sulfonate gemini surfactants was synthesized through esterification of renewable linoleic acid with various alcohols and subsequent sulfonation with readily available sodium hydrogensulfite (NaHSO3). Organocatalytic sulfonation of methyl linoleate with NaHSO3 by the triethylamine and tert‐butyl peroxybenzoate catalyst system was investigated, where a methyl linoleate conversion of 96.4% could be achieved while generating high purity product without tedious purification. Three resulting sodium alkyl linoleate disulfonates (SALDs) have been characterized by Fourier transform infrared, high‐performance liquid chromatography, LC–MS, high‐resolution mass spectrometry (HR–MS), nuclear magnetic resonance techniques, and thermogravimetric analysis. The physicochemical properties and surface properties of the SALDs at various concentrations were investigated. The results showed that the SALDs exhibited low Krafft temperature, high water solubility, foam stability (foam half‐life time could reach 15 min), emulsifying ability (emulsification time of 2.0 g/L is 192 s), and good thermal stability. This study enriches the family of anionic gemini surfactants and provides reference data for facile preparation of gemini surfactants.

“…Diels-Alder type reactions produce rosin derivatives such as fumaropimaric acid (FPA), acrylicpimaricacid (APA), maleopimaric acid (MPA), and methyl maleopidate (MMP). Owing to their structural characteristics, low cost, biodegradability, biocompatibility, and corrosion resistance, rosin and its derivatives are valuable feedstocks for an array of polymers [9,10] and have found a broad range of applications [8], such as coatings [11][12][13][14][15][16][17][18], packaging [19,20], electrical equipment [6], antibacterial and antiviral polymers [19,[21][22][23][24], surfactants, and adhesives [25][26][27][28][29]. Hence, the replacement of BPA with rosin and its derivatives as a fossil feedstock has gained increasing attention [4,5,[30][31][32][33].…”

This study aims to reveal the effects of flexible chain lengths on rosin-based epoxy resin’s properties. Two rosin-based epoxy monomers with varying chain lengths were synthesized: AR-EGDE (derived from ethylene glycol diglycidyl ether-modified acrylic acid rosin) and ARE (derived from acrylic acid rosin and epichlorohydrin). Diethylenetriamine (DETA), triethylenetetramine (TETA), and tetraethylenepentamine (TEPA) with different flexible chain lengths were used as curing agents. The adhesion, impact, pencil hardness, flexibility, water and heat resistance, and weatherability of the epoxy resins were systematically examined. It was found that when the flexible chains of rosin-based epoxy monomers were grown from ARE to AR-EGDE, due to the increased space of rosin-based fused rings, the toughness, adhesion, and water resistance of the rosin-based epoxy resins were enhanced, while the pencil hardness and heat resistance decreased. However, when the flexible chains of curing agents were lengthened, the resin’s performance did not change significantly because the space between the fused rings changed little. This indicates that the properties of the rosin-based resins can only be altered when the introduced flexible chain increases the space between the fused rings. The study also compared rosin-based resins to E20, a commercial petroleum-based epoxy of the bisphenol A type. The rosin-based resins demonstrated superior adhesion, water resistance, and weatherability compared to the E20 resins, indicating the remarkable durability of the rosin-based resin.
