Palm oil was used as the oil phase of the microemulsion. Experimental results indicate that the optimum triglyceride microemulsion was achieved when equal mass of palm oil and the aqueous phase containing 3 wt% sodium chloride, 1 wt% alkyl polyglycosides, 3 wt% glyceryl monooleate, and 93 wt% de-ionized water were mixed. The formulated composition of the aqueous phase was able to form translucent Winsor Type I microemulsion with palm oil at ambient conditions. The measured interfacial tension between the optimum microemulsion and the model oil, which is n-octane in this study, was 0.0002 mN/m. The maximum tertiary oil recovery of 71.8% was achieved
selleck inhibitor after the injection of the optimum microemulsion formulation to a sand pack. The significant increase in total oil recovery (87%) suggests the effectiveness of the triglyceride microemulsion formulation for enhanced oil recovery. Its capability in recovering additional oil (4.3% of the trapped oil after water flooding)
compared to a typical polymer in tertiary oil recovery indicates the efficiency of the optimum triglyceride microemulsion formulation. (C) 2012 Elsevier B.V. All rights reserved.”
“A methodologically chemorational approach HCS assay to the design of PGB structures was demonstrated using a PGB type misoprostol analog as an example.”
“Transformations of diepoxy derivatives of terpinolene under conditions of homogeneous and heterogeneous acid catalysis were studied. Qualitative and quantitative compositions of the reaction mixtures were found to depend on the acidity of the medium and mutual orientation of the epoxide rings in the p-menthane skeleton. The experimental data were compared with the results of computer simulation of the most probable transformation pathways in terms of molecular mechanics and quantum-chemical methods.”
“It is no secret that during microemulsion flooding, the oil entrapped in rock GDC-0973 purchase pores can be easily removed when a new Winsor Type III microemulsion is
formed in situ. Formulation of an efficient microemulsion in tertiary oil recovery requires good understanding of its phase behavior. This paper presents the phase behavior study of a triglyceride microemulsion before and after n-octane solubilization in formulating an efficient triglyceride microemulsion. The effects of solubilized oil as co-oil, salinity, surfactant concentration and co-surfactant concentration on the phase behavior of a triglyceride microemulsion were investigated. The optimized aqueous phase composition of the triglyceride microemulsion was adjusted at 1 wt% alkyl polyglycosides, 3 wt% glyceryl monooleate, 3 wt% sodium chloride, and 93 wt% de-ionized water.
