Oil aromatization

Preparation and Properties of Organophosphines. AUphatic phosphines can be gases, volatile Hquids, or oils. Aromatic phosphines frequentiy are crystalline, although many are oils. Some physical properties are Hsted in Table 14. The most characteristic chemical properties of phosphines include their susceptabiUty to oxidation and their nucleophilicity. The most common derivatives of the phosphines include halophosphines, phosphine oxides, metal complexes of phosphines, and phosphonium salts. Phosphines are also raw materials in the preparation of derivatives, ie, derivatives of the isomers phosphinic acid, HP(OH)2, and phosphonous acid, H2P(=0)0H.

Water-immiscible, volatile, or more likely nonvolatile liquids such as vegetable oils, aromatic and aliphatic hydrocarbons (mineral oil), medium-chain triglycerides, and acetylated glycerides. 

One major question of interest is how much asphaltene will flocculate out under certain conditions. Since the system under study consist generally of a mixture of oil, aromatics, resins, and asphaltenes it may be possible to consider each of the constituents of this system as a continuous or discrete mixture (depending on the number of its components) interacting with each other as pseudo-pure-components. The theory of continuous mixtures (24), and the statistical mechanical theory of monomer/polymer solutions, and the theory of colloidal aggregations and solutions are utilized in our laboratories to analyze and predict the phase behavior and other properties of this system. 

The methods include the use of mass spectrometry to determine (1) the hydrocarbon types in middle distillates (ASTM D2425) (2) the hydrocarbon types of gas oil saturate fractions (ASTM D2786) (3) the hydrocarbon types in low-olefin gasoline (ASTM D2789) and (d) the aromatic types of gas oil aromatic fractions (ASTM D3239). 

Solvent dewaxing removes wax from lubricating oil stocks, promoting crystallization of the wax. Solvents include furfural, phenol, cresylic acid-propane (DuoSol), liquid sulfur dioxide (Eleleanu process), B,B-dichloroethyl ether, methyl ethyl ketone, nitrobenzene, and sulfur-benzene. The process yields de-oiled waxes, wax-free lubricating oils, aromatics, and recovered solvents.

Sauer and Fitzgerald [9] have described thin layer chromatographic technique for the identification of water-borne petroleum oils. Aromatic and polar compounds are removed from the sample by liquid-liquid extraction with acidified methanol, the extract is chromatographed on a silica gel thin layer plate, and the separated components are detected by their fluorescence under long- and short-wave ultraviolet light. Unsaturated non-fluorescing compounds are detected by iodine staining. 

An optoelectronic image device has been used as an HPLC detector to obtain UV absorption spectra of shale oil aromatic hydrocarbons separated isocratically (10). Since isocratic separations maintain a constant mobile phase composition, the...

Until now, oil-phospholipid mixtures, raw seed oils, aromatic vegetable oils, essential oils aqueous solutions and aqueous dispersions have been sprayed and extracted with supercritical C02 in the high pressure spraying apparatus (Figurel). For instance aqueous roasted coffee extract was sprayed with CO2 in order to rise concentration for posterior production of instant powder. Due to low process pressures (under 20 MPa) and increased... 

Olive oil aromatized with chili pepper is a common condiment in the Mediterranean area. Under these conditions, transamidation of capsaicin to N-oleoylvanillamrne (olvanil, 69a) has been demonstrated [122]. Olvanil is nonpungent, but more potent as an anti-inflammatory agent than capsaicin, and one therefore wonders if olvanil might also contribute to the beneficial health effects traditionally attributed to olive oil flavored with hot pepper. 

The carbon-number distributions (35) for the CnH2n+zO compounds in the oil neutrals are relatively short and exhibit maxima near the center of each Z(O) series. In contrast, the carbon-number distributions for the asphaltene-neutral Z(O) compounds are characterized by the occurrence of maximums in the beginning of each distribution. The origin of the differences in these Z(O) distributions is not clear. Furthermore, the former result contrasts with the result obtained for the oil aromatic hydrocarbons and the latter parallels the distribution of weight percents in each Z(H) series for the asphaltene neutrals. It is tempting to ascribe the difference in the distribution of weight percents of the various Z(O) compound types in the oil and asphaltene neutrals to the chemistry associated with the COED process. However, the fact that considerable overlap exists in the neutral-aromatic Z(O) compounds between the oils and asphaltenes precludes this conclusion because the results could reflect phenomena associated with solvent extraction.
