Bio-based surfactants have attracted increasing attention due to their renewable resources and excellent surface properties. In this study, a novel bio-based sulfonic zwitterionic surfactant (BSZS) derived from transgenic soybean oil was prepared using a simple reaction route with two steps of the amidation and quaterisation. The bio-based sulfonic zwitterionic surfactant showed a critical mice...

This work describes an environmentally friendly method for pretreating rice straw by using 1-Allyl-3-methylimidazolium chloride ([AMIM]Cl) as an ionic liquid (IL) assisted by surfactants. The impacts of surfactant type (including nonionic-, anionic-, cationicand bio-surfactant) on the ionic liquid pretreatment were investigated. The bio-surfactant+IL -pretreated rice straw showed significant li...

This paper presents a set of surfactant-selection guidelines that can be used to design bio-based semi-synthetic metalworking fluid (MWF) microemulsions as a renewable alternative to conventional petroleum formulations. Ten surfactant classes (six anionic and four nonionic) with different head and tail structures and three vegetable base oils (canola oil, soybean oil, and a fatty acid trimethyl...

using environmental-friendly methods in order to remove or reduce oil pollutants and their derivations in the environment are developing. in this study, the biodegrading ability of bacillus subtilis .sp which has been separated from oil-polluted soil was examined. it was revealed that it can reduce surface tension of growth medium and produce bio-surfactant at 37 and 20 degrees centigrade. also...

A bio-inspired complex, [(bpbpmp)Fe(III)(m-OAc)(2)Cu(II)](ClO(4)), was combined with a zwitterionic surfactant (ImS3-14) stabilizing pre-formed palladium nanoparticles and coated on a glassy carbon electrode (GCE). This bio-inspired surfactant film was capable of catalyzing redox reactions of dihydroxybenzenes, thus allowing the simultaneous electrochemical quantification of CC and HQ in cigare...

This article describes the synthesis of a new bio-based organocatalytic surfactant. The nine steps were optimized, fully respecting principles green chemistry. surfactant aspect was then evaluated with use tensiometric studies. molecular organization in vesicles an aqueous medium characterized by Dynamic Light Scattering (DLS) and confirmed using Density Functional Theory (DFT) modelling.

In the asphalt industry, bituminous emulsions are widely used in road pavement operations and building/construction processes such as cold mix waterproofing processes, respectively. A very important fact to keep mind is that not all types of bitumen suitable for realization emulsions. This largely due variation their chemical nature different cracking carried out on during fractional distillati...

Waste cooking oil (WCO) is a kind of non-edible oil with enormous quantities and its unreasonable dispose may generate negative impact on human life and environment. However, WCO is certainly a renewable feedstock of bio-based materials. To get the rebirth of WCO, we have established a facile and high-yield method to convert WCO to bio-based zwitterionic surfactants with excellent surface and i...
