Immiscible hydrocarbon

Another microbial polysaccharide-based emulsifier is Hposan, produced by the yeast Candida lipolytica when grown on hydrocarbons (223). Liposan is apparentiy induced by certain water-immiscible hydrocarbons. It is composed of approximately 83% polysaccharide and 17% protein (224). The polysaccharide portion consists of D-glucose, D-galactose, 2-amino-2-deoxy-D-galactose, and D-galacturonic acid. The presence of fatty acyl groups has not been demonstrated the protein portion may confer some hydrophobic properties on the complex.

P 15] The reservoir of the dielectrophoretic droplet mixer was filled with 1-bromo-dodecane, a low-permittivity, low-viscosity, water-immiscible hydrocarbon [99]. AC signals of up to 180 Vp p and frequencies between 5 and 500 kHz were formed using a programmable function generator and amplified by variable gain amplifiers. 

In making all operating and design decisions. It Is Important to keep in mind the definition of the true reaction zone. Fundamentally, this Is the Interfaclal area between the immiscible hydrocarbon and acid catalyst liquid phases in the reactor. Reactants and products flow across this boundary. The olefins In the feed stream react Instantaneously with the sulfuric acid catalyst and combine with the relatively small amount of isobutane present In solution In the acid catalyst to form alkylate. Alkylate passes out through the Interfaclal surface reaction boundary into the hydrocarbon phase while Isobutane passes in to resaturate the catalyst. To suppress undesirable polymerization and other reactions It Is necessary to ... 

Quenching in product oil or in an immiscible hydrocarbon solvent is widely practiced. Orthodox aerosol capture devices such as demisters and other commonly used impingement devices are not very effective and electrostatic precipitation is currently the preferred method. 

A plot of (cos 9e) versus (Ylv/Hv) gives a straight line with an origin at (cos 0e = —1), and with a slope of 2Fowkes assumed that (y= yLv) for all non-polar liquids, and cal culated (ys ) values of some nonpolar polymers by using Equation (688). He later evaluated the 7lv values for polar liquids as a fraction of their total yy, initially for water by using water-immiscible hydrocarbon liquid interactions. He used an empirical equation,... 

Advances in technology have enabled microlenses to be designed and fabricated by a variety of methods. Biebuyck et al. introduced a method to form microlenses, also by utilizing surface tensions [8]. Self-assembled monolayers (SAMs) are used to pattern hydrophobic and hydrophilic regions. Water and immiscible hydrocarbon fluids (oils) exhibit different wettability characteristics in these two regions. Water droplets are segregated from hydrocarbon fluid at the surface of the SAM and thus form lenses. 

Without any sophisticated instrumentation, some most important types of fluid inclusion are easily recognized under the petrographic microscope (for a complete and detailed description of the criteria see Roedder, 1972). Most common fluids may be classified as aqueous H2O (Fig. 1.2), H2O + NaCl (Fig. 1.3), H2O + NaCl + many other daughter minerals (l + in Volhynia pegmatite, each a different species, lyakhov, I967), H2O + immiscible hydrocarbons and oil, carbonic (CO2 dissolved hydrocarbons. Fig. l.k and 5) and composite (H2O + CO2, Fig. l.l). Similar in appearance to some of these fluid inclusions are glassy (Clochiatti, 1975) and empty low density gas inclusions, which must be checked by microthermometry (see below). ...
