Polymer relies on its special properties, which is an effective means to enhance oil recovery. But the composition of its produced liquid is very complex, especially emulsifying phenomenon severely constrains the process oil-water separation at a later stage. At present technical means of demulsification taken by both home and abroad oilfield mainly include physics, chemistry and other methods....

We recently reported on the synthesis of different chain length α,ω-diester monomers from plant oil derived fatty acid esters or fatty alcohols via olefin cross-metathesis with methyl acrylate taking advantage of natures "synthetic pool" of fatty acids with different chain lengths and positions of double bonds. [1,2,3] Similarly, we could show that their cross-metathesis with allyl chloride all...

The implications arising from the distribution of offset ink components in a paper coating structure are presented. The work focuses on two mechanisms causing differential distribution of ink constituents, namely (a) adsorption chromatography, resulting from coating pigment chemistry and morphology variables, and (b) latex-oil diffusional interaction. Adsorption chromatographic fractionation an...

Easily accessible, primitive chemical structures produced by self-assembly of hydrophobic substances into oil droplets may result in self-moving agents able to sense their environment and move to avoid equilibrium. These structures would constitute very primitive examples of life on the Earth, even more primitive than simple bilayer vesicle structures. A few examples of simple chemical systems ...

Canada has experienced a significant increase in the transport of diluted bitumen (dilbit), a predominant oil sands product that combines bitumen with diluents derived from oil-gas condensates and other proprietary compounds. The proportion of diluent and the chemical composition of dilbit vary to meet seasonal transport requirements. While the toxic effects of a variety of crude and refined oi...

Nannochloropsis oculata is a marine-water microalgae that is considered to be a good source of omega-3 fatty acids, specifically eicosapentaenoic acid (EPA), utilized in the production of an omega-3 oil for use as a dietary supplement. This study investigates the safety of N. oculata in male and female Sprague-Dawley rats administered a 0 or 10 mL/kg bw/rat N. oculata (10E8 viable cells/mL) sus...
