Solubility. One of PVP s more outstanding attributes is its solubility in both water and a variety of organic solvents. PVP is soluble in alcohols, acids, ethyl lactate, chlorinated hydrocarbons, amines, glycols, lactams, and nitroparaffins. SolubiUty means a minimum of 10 wt % PVP dissolves at room temperature (moisture content of PVP can influence solubiUty). PVP is insoluble in hydrocarbons, ethers, ethyl acetate, j -butyl-4-acetate, 2-butanone, acetone, cyclohexanone, and chlorobenzene. Both solvent polarity and H-bonding strongly influence solubiUty (77). 

The submitters have found that diglyme and 1,2-dimethoxyethane are also effective solvents. The reactivity of the magnesium obtained with 1,2-dimethoxyethane as solvent is slightly reduced. Hydrocarbons, amines, and dioxane proved to be ineffective solvents owing to the insolubility of the magnesium salts and consequent incomplete reduction. 

Solvents can be classified into three categories according to their polarity namely, polar protic, dipolar aprotic and non-polar. Most of the common solvents fall under one of following chemical classes Aliphatic hydrocarbons, aromatic hydrocarbons, alcohols, phenols, ethers, aldehydes, ketones, carboxylic acids, esters, halogen-substituted hydrocarbons, amines, nitriles, nitro-derivatives, amides and sulfur-containing solvents (Marcus, 1998). In certain cases a mixture of two or more solvents would perform better than a single solvent. 

Resistance is poor versus ketones, esters, ethers, aromatic and halogenated hydrocarbons, amines, and phenols. 

It is very reactive substance. A trace amt (0.05% by wt) of F203 dissolved in liq oxygen makes the resultant oxidizer capable of hyper-golic ignition with common hydrocarbons, amine base fuels or hydrogen and provides more stable combstn... 

Both before and after the commercial introduction of tetraethyllead antiknocks, many other substances have been considered as octane-number improvers. Chief among them are hydrocarbons, amines, and other organometallic compounds. 

All data on the kinetics of the catalytic dehydrogenation of hydrocarbons, amines, and alcohols obtained in our laboratory are expressed by the equation 12) ... 

The Nature of Reactants. No less effect on z and e is exerted by the nature of the reacting atoms of the molecule. The values of z and e are distinctly different for hydrocarbons, amines, and alcohols (on the same or similar catalysts). This complies with the multiplet theory of catalysis, according to which in the three reactions the following atomic groups, in which the vertical bonds pass over to the horizontal, are in contact with the catalyst ... 

The oxidation potentials 170 ——- 777 of a large number of aromatic hydrocarbons, amines, phenols,heterocycles and olefins are tabulated I0,10a>25-48 65,525-528) an(j nee(j not repeated here. Such potentials have been successfully correlated with HMO-parameters 525 530>538) ie in oxidations with the energy of the highest filled MO (HFMO).Adams 25) and Peover 65) have discussed some precaution to which attention should be paid in such correlations, e.g., shifts in potentials due to the irreversibility of the electrode process or due to fast follow-up reactions. 

In spite of the known phases, the advantage of suggested selective immovable phase is the possibility of selective analysis of various classes of organic and organosilicon compounds. Of spe-cial attention should be peculiarity of the phase to separation of cyclic and naphthene hydrocarbons, amines and alcohols with preservation of high thermal stability. 

Deuterium incorporation in the aromatic hydrocarbon/amine systems is usually considered as involving the radical anion of the aromatic hydrocarbon. CIDNP studies (Gardini and Bargon, 1980) have drawn attention to the fact that trialkylaminium ions undergo fast proton exchange and hence... 

Capillary electrophoresis has been used for the analysis of chiral pollutants, e.g., pesticides, polynuclear-aromatic hydrocarbons, amines, carbonyl compounds, surfactants, dyes, and other toxic compounds. Moreover, CE has also been utilized to separate the structural isomers of various... 

The following were groups of compounds used as fuels hydrocarbons, amines, hydrazines, boranes and as oxidizers nitric acid, nitrogen oxides, hydrogen peroxide, liquid oxygen, halogens.
