Other inorganic solvents

Liquid-vapour equilibria for Cl -COCl have been calculated on the assumption that the system conforms to ideality [541]. In the region of low dichlorine concentration ( 2.5%), the system has been shown, by analysis of the gas and liquid phases, to behave consistently with these calculations. The temperature-composition diagrams are illustrated in Fig. 6.13 at 101.3 and 152.0 kPa [541]. 

COClj is regarded generally as being soluble in CS, S Clj d some of the liquid metal chlorides, such as SnCl and SbCl [132]. It is also soluble in both

Some other inorganic solvents were tried with Li anodes as well (16-18). 

The symbol for the electron in tables of values of E° in liquid ammonia is thus equivalent to NH3(1) + /iH2(g /= 1) NH4+(liq NH3 a = 1). As for aqueous solutions, several secondary reference electrodes have proved more convenient for the actual measurement of E° in liquid ammonia, e.g. silver/silver chloride. This procedure has been applied to other inorganic solvents and numerous organic solvents, and tables of values are readily available.32... 

Phenyldiazonium chloride and other similar diazonium compounds are very soluble in water, are completely insoluble in ether and other organic solvents, and are completely dissociated in aqueous solution to organic cations and inorganic anions (e.g., chloride ions) a convenient formulation is therefore, for example, CjHjNj+CP. 

Acetyl chlotide reacts with aromatic hydrocarbons and olefins in suitably inert solvents, such as carbon disulfide or petroleum ether, to furnish ketones (16). These reactions ate catalyzed by anhydrous aluminum chlotide and by other inorganic chlotides (17). The order of catalytic activity increases in the order... 

Chemical Properties. A combination of excellent chemical and mechanical properties at elevated temperatures result in high performance service in the chemical processing industry. Teflon PEA resins have been exposed to a variety of organic and inorganic compounds commonly encountered in chemical service (26). They are not attacked by inorganic acids, bases, halogens, metal salt solutions, organic acids, and anhydrides. Aromatic and ahphatic hydrocarbons, alcohols, aldehydes, ketones, ethers, amines, esters, chlorinated compounds, and other polymer solvents have Httle effect. However, like other perfluorinated polymers,they react with alkah metals and elemental fluorine. 

Inorg nic Colora.nts. In addition to various white pigments, other inorganic colorants such as those Hsted in Table 9 are used in a number of cosmetic products. These usually exhibit excellent lightfastness and are completely insoluble in solvents and water. 

For the size exclusion chromatography of proteins on silica-hased diol packings, it is generally recommended to use fully aqueous mobile phases with a salt concentration between 0.1 and 0.3 M. In general, a phosphate buffer around pH 7 is used as the mobile phase. Under these circumstances, the tertiary structure of most proteins is preserved without difficulty and the interaction of proteins with each other is minimized. However, other inorganic buffers or combinations of buffers with organic solvents can be used without difficulties for special applications. 

Inorganic polysulfides are ionic substances containing chain-like dianions Sn - 8uch ions are formed in numerous reactions, e.g., by oxidation of monosulfide ions H8 in water or other polar solvents as well as by reaction of aqueous monosulfide with sulfur-rich compounds including elemental sulfur ... 

The information available is collected in Table XXXI (46,149,157, 160,291,292,305-310). There are remarkably few data for hydroxylic solvents, but a reasonable amount for some aprotic solvents, especially ethers. Cerium tribromide is sparingly soluble in liquid ammonia (278) information on solubilities of tribromides in other inorganic non-aqueous solvents seems entirely lacking. Comparisons between tribromide and trichloride solubilities can readily be made using Tables XXIV to XXXI. 

Refineries employ a wide spectrum of contact solvent processes, which are dependent upon the differential solubilities of the desirable and undesirable feedstock components. The principal steps are countercurrent extraction, separation of solvent and product by heating and fractionation, and solvent recovery. Naphthenics, aromatics, unsaturated hydrocarbons, and sulfur and other inorganics are separated, with the solvent extract yielding high-purity products. Many... 

The cross-sectional flow velocity through the resin columns was maintained at 10 cm/min. The columns were each rinsed with 2.5 bed volumes of 1 M HC1 followed by 2.5 bed volumes of distilled water to remove metallic oxides and other inorganic constituents. Finally, the organic components were eluted with 2.5 bed volumes of 95 ethanol. Ethanol was selected as the eluent because it seemed to be the best choice as a solvent tolerated by animals used in proposed biological tests.

There are many methods for effecting the nitration of aromatic compounds. Reactive compounds, for example, phenol, will nitrate in dilute nitric acid, but usually more vigorous reaction conditions consisting of nitric acid (either concentrated or fuming) or nitrate salts in sulfuric acid are used. Solutions of nitric acid in other mineral acids, e.g., perchloric or phosphoric acid, have sometimes been used and can give nitro products in isomeric proportions different from those found in sulfuric acid solution. Nitric acid inorganic solvents, particularly acetic acid or acetic anhydride, has also been used frequently. In acetic anhydride acetyl nitrate rather than the nitronium ion is usually the reacting species. 

Other inorganic polymers, such as silicones, have excellent optical and mechanical properties for optical membranes. A great number of easily handled commercial silicone prepolymers are available but they have some disadvantages towards other materials. The surface is not easily modifiable to covalently immobilize indicators, they are not suited to combine with the customarily used support structures, owing to hard adhesion, and they are bad solvents for most of the indicators.
