Sodium Cardanol Sulfonate Surfactant from Cashew Nut Shell Liquid

Abstract: Sodium cardanol sulfonate surfactant was synthesized from cardanol from cashew nut shell liquid. Surfactant properties of cardanol sulfonate were determined and compared with dodecylbenzene sulfonate. Surface tension values were determined to be 32.25 mN/m for cardanol sulfonate at 20% w/v and 28.00 mN/m for dodecylbenzene sulfonate at 15% w/v. Critical micelle concentrations of dodecylbenzene sulfonate and cardanol sulfonate were found to be 0.435 and 0.372 mol/L, respectively. In comparison with dodecylbenze… Show more

“…The polyetoxylates of cardanol and 3-pentadecyphenol appeared to be similar in surfactancy, but cardol polyetoxylate exhibited a relatively smaller reduction in surface tension [25]. Sodium cardanol sulfonate was found to be useful as an alternative anionic surfactant with a CMC of 0.372 M and a relative detergency of 93.7% compared with dodecylbenzene sulfonate [26].…”

“…1). This plot shows that the acrylate surfmer based on hydrogenated cardanol exhibit a reduction in surface tension with a low CMC value reported in the literature [20] for other derivatives. For example, 0.5% w/v solution of cardanol sulfonate was reported to possess a surface tension of 32.25 mN/m with a CMC value of 0.372 mol/L.…”

“…This is expected to influence the reactivity of the acrylate group and hence its incorporation efficiency during emulsion polymerization [18]. It is anticipated that S1 reactivity will be higher than that of S2, because the acrylate group is conjugated to the electron withdrawing effect of the sulfonate group and phenolic nuclei [20]. The reactivity of S2 may be comparable to that of ordinary acrylates, as the acrylate group is isolated from the electron withdrawing effect of phenolic ring and sulfonate group.…”

“…Em função do acúmulo de poluição marinha provocada por essas substâncias, 78 derivados polietoxilados do LCC foram investigados, o que resultou em uma patente com um novo composto, de detergência similar ao nonilfenol polietoxilado comercial e biodegradabilidade superior. 79 Seguindo essa mesma linha, Peungjitton e colaboradores 80 sintetizaram e analisaram as características físico-químicas de um novo surfactante sulfonado derivado do cardanol, comparando suas propriedades com as do surfactante comercial dodecilbenzeno sulfonato de sódio (DBS). Resultados de CMC (concentração micelar crítica), tensão superficial e detergência, fazem do cardanol sulfonato de sódio (CDS) uma possível alternativa comercial ao DBS (Figura 9).…”
