Grape seed oil is a product resulting from the processing of grape marc. It is ever more appealing for the cosmetic and pharmaceutical industries: the pharmaceutical activities concern its antioxidant properties, due to the large content of unsaturated fatty acids. Grape seed oil could be extracted mechanically by pressing or chemically by means of solvents. Among the latter, supercritical CO2 ...

In this work, an N-butyl-pyridinium-based ionic liquid [BPy]BF(4) was prepared. The effect of extraction desulfurization on model oil with thiophene and dibenzothiophene (DBT) was investigated. Ionic liquids and hydrogen peroxide (30%) were tested in extraction-oxidation desulfurization of model oil. The results show that the ionic liquid [BPy]BF(4) has a better desulfurization effect. The best...

Sandalwood and its oil, is one of the oldest known perfume materials and has a long history (more than 4000 years) of use as mentioned in Sanskrit manuscripts. Sandalwood oil plays an important role as an export commodity in many countries and its widely used in the food, perfumery and pharmaceuticals industries. The aim of this study is to know and verify the kinetics and mechanism of microwav...

For many years, commercial-grade hexane has been the preferred solvent for extracting oil from cottonseed. Recent environmental and health concerns about hexane may limit the use of this solvent; therefore, the need for a replacement solvent has become an important issue. Heptane is similar to hexane, but does not have the environmental and health concerns associated with the latter. On a labor...

Moringa oleifera, seed (PKM 1) was examined for extracted oil recovery under the different designed conditions using Central composite face centered design of Response surface methodology. The kinetics of extraction was investigated and its parameters were determined based on a second order model. The optimum conditions were found at 3.6 h reaction time, temperature, 67.84°C and solvent to soli...

On the timing of non-renewable resource extraction with regime switching prices This paper develops a model of a profit maximizing firm with the option to exploit a nonrenewable resource, choosing the timing and pace of development. The resource price is modelled as a regime switching process, which is calibrated to oil futures prices. A HamiltonJacobi-Bellman equation is specified that describ...

The antibacterial effect of Emblica officinalis essential oil was investigated against Staphylococcus aureus. The solvents used for extraction of essential oil were methanol, dichloromethane, hexane and chloroform. In vitro antibacterial activity was performed by agar well diffusion method. The results obtained in the present study suggest that Emblica officinalis essential oil used the treatme...
