Thus, the objective of this work was the development of novel environmentally friendly amino acid surfactants. Combining Diels–Alder cyclization of myrcene with maleic or citraconic anhydride followed by ring opening with amino acids enabled a synthesis route with a principal 100% atom economy. Variation of amino acids resulted in a large structural variety of anionic and amphoteric surfactants. Lysine gave access to either a mono-acylated product bearing a cationic side chain or a bi-acylated gemini surfactant. First, anhydride precursors were synthesized in yields of >90% in a Diels–Alder reaction under microwave radiation and subsequent amino acid coupling in aqueous environment gave fully bio-based surfactants in good yields and purity. Physicochemical characterization showed an enhanced decrease in surface tension upon addition of amino acids to the myrcene–anhydride backbone, resulting in a minimal value of 31 mN·m−1 for gemini–lysine. Foamabilitiy and foam stability were significantly increased at skin-friendly pH 5.5 by incorporation of amino acids. The carboxylic groups of surfactants with arginine were esterified with ethanol to access cationic compounds. Comparative analysis revealed moderate antimicrobial effects against yeast, Gram-positive bacteria, and Gram-negative bacteria.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140522208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, halloysite (HAL) clay, obtained from the Thach Khoan, Vietnam, was utilized for the removal of Co2+ ions from an aqueous solution, and the influence of different factors on the adsorption properties of Co2+ was investigated. Optimal conditions determined were 0.8 g HAL mass per 50 mL of solution, initial Co2+ concentration of 40 mg·L−1, contact time of 80 min, pH0 of 6.09, and room temperature of 30°C. Under these conditions, the adsorption efficiency and capacity obtained were 76.358 ± 0.981% and 1.909 ± 0.025 mg·g−1, respectively. The adsorption process followed the Langmuir adsorption isotherms, with a maximum monolayer adsorption capacity of 3.10206 ± 0.13551 mg·g−1, and exhibited a pseudo-second-order kinetic model. Desorption experiments were conducted using the electrochemical method with a deep eutectic solvent based on choline chloride and urea (reline).
