Tea saponin (TS) is a relatively inexpensive natural nonionic surfactant extracted from parts of tea plants, which can be modified into an anionic surfactant to achieve better surface activity. In this paper, the synthesis of TS‐based succinic acid sulfonate as an anionic foaming agent is described. TS used as the hydrophobic source was modified by maleic anhydride (MAH) and then reacted with sodium bisulfite. Orthogonal experiment of a 2‐step reaction was designed and performed, resulting in 9 kinds of succinic acid tea‐saponin sulfonate (STS). 4‐Dimethylaminopyridine and tetrabutylammonium bromide were, respectively, used as catalyst for the esterification with MAH and the sulfonation with sodium bisulfite. During the synthesis process, N,N‐dimethylformamide was employed as the solvent and ethyl acetate as the extractant. The molecular structure of STS was confirmed by infrared spectroscopy and mass spectrometry. The foaming property of STS was investigated through comparison with different kinds of common surfactants. The results show great prospects of these environmentally friendly anionic surfactants.

“…crop has attracted huge economic interests in China. In recent years, the plantation of C. oleifera has increased by a yearly rate of 5.4% [3]. As byproducts from the tea oil processing industry, the outputs of tea oil fruit hull (TOFH), seed shell, and oil cake have reached around 5 million tons every year [4].…”

“…Considering of rich bioactive substances in the seed shell and oil cake, much attention has been paid to valorization of these byproducts [3, 5]. However, the use of TOFH is very limited, though it accounts for ~75% of these total byproducts [6].…”

BackgroundAs a natural renewable biomass, the tea oil fruit hull (TOFH) mainly consists of lignocellulose, together with some bioactive substances. Our earlier work constructed a two-stage solvent-based process, including one aqueous ethanol organosolv extraction and an atmospheric glycerol organosolv (AGO) pretreatment, for bioprocessing of the TOFH into diverse bioproducts. However, the AGO pretreatment is not as selective as expected in removing the lignin from TOFH, resulting in the limited delignification and simultaneously high cellulose loss.ResultsIn this study, acetic acid organosolv (AAO) pretreatment was optimized with experimental design to fractionate the TOFH selectively. Alkaline hydrogen peroxide (AHP) pretreatment was used for further delignification. Results indicate that the AAO–AHP pretreatment had an extremely good selectivity at component fractionation, resulting in 92% delignification and 88% hemicellulose removal, with 87% cellulose retention. The pretreated substrate presented a remarkable enzymatic hydrolysis of 85% for 48 h at a low cellulase loading of 3 FPU/g dry mass. The hydrolyzability was correlated with the composition and structure of substrates by using scanning electron microscopy, confocal laser scanning microscopy, and X-ray diffraction.ConclusionThe mild AAO–AHP pretreatment is an environmentally benign and advantageous scheme for biorefinery of the agroforestry biomass into value-added bioproducts.Electronic supplementary materialThe online version of this article (doi:10.1186/s13068-017-0777-1) contains supplementary material, which is available to authorized users.

“…Такое неидеальное поведение растворов смесей ПАВ требует детального изучения с целью получения желательных структур, не прибегая к синтезу новых веществ. Тем не менее исследованию смесей ПАВ посвящено ограниченное количество работ, интерес к ним возник в последнее десятилетие [8][9][10][11]. В них в основном рассматривается поведение смесей ПАВ на границе водный раствор / воздух в мицеллярных системах.…”
