Aromatic hydrocarbons alcohols

Most organic compounds, including aromatic hydrocarbons, alcohols, esters, ketones, ethers, and carboxyUc acids are miscible with nitroparaffins, whereas alkanes and cycloalkanes have limited solubiUty. The lower nitroparaffins are excellent solvents for coating materials, waxes, resins, gums, and dyes. 

Polydiethylene glycol succinate 50-200° Aromatic hydrocarbons, alcohols, ketones, esters. 

Deposition Precursors. Diamond has been deposited from a large variety of precursors which include, besides methane, aliphatic and aromatic hydrocarbons, alcohols, ketones, and solid polymers such as polyethylene, polypropylene, and polystyrene, and halogens. 

In fact, fluorinated polyphosphazenes are usually considered to be extremely stable towards chemical agents and aggressives due to the presence of C-F bonds in the side phosphorus substituents. PTFEP, for instance, appears to be completely insensitive to several, most common, solvents (aliphatic and aromatic hydrocarbons, alcohols and water), to acids (e.g. acetic acid), and to bases (e.g. pyridine and concentrated NaOH solutions), although some decomposition could be observed in triethylamine and in concentrated H2SO4 [41]. Phos-phazene fluoroelastomers, moreover, are known to be completely insoluble in aromatic solvents [533] and petroleum-resistant materials [502-506,552].

This technique has been applied to the determination of aromatic hydrocarbons, alcohols, aldehydes, ketones, chloroaliphatic compounds, haloaromatic compounds, acrylonitrile, acetonitrile, mixtures of organic compounds and tetrahydrothiophene in soils, chloroaliphatic and haloaromatic compounds and organotin compounds in non-saline sediments, and organotin compounds in saline sediments. 

For more volatile compounds in soils, such as aromatic hydrocarbons, alcohols, aldehydes, ketones, chloroaliphatic hydrocarbons, haloaromatic hydrocarbons, acetonitrile, acrylonitrile and mixtures of organic compounds a combination of gas chromatography with purge and trap analysis is extremely useful. Pyrolysis gas chromatography has also found several applications, heteroaromatic hydrocarbons, polyaromatic hydrocarbons, polymers and haloaromatic compounds and this technique has been coupled with mass spectrometry, (aliphatic and aromatic hydrocarbons and mixtures of organic compounds). 

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. 

The chemical resistance is generally inferior to that of comparable polyethylenes and decreases when VA rises. EVAs are attacked by concentrated strong acids, halogens, oxidizing acids, chlorinated solvents, certain oxidants, aliphatic and aromatic hydrocarbons, alcohols, ketones, esters, and some others. 

Most of the 2-amino-4H-pyrans are colorless, pale-yellow, or pale-cream crystals with high melting points. They are readily soluble in aromatic hydrocarbons, alcohols, acetone, acetonitrile, chloroform, DMF, and DMSO, and nearly insoluble in hexane and water. 

Correlation of Qrlgoras Grigoras [25] derived a simple linear correlation to estimate V °(cm3 mol-1) for liquid compounds, including saturated, unsaturated, and aromatic hydrocarbons, alcohols, acids, esters, amines, and nitriles ... 

A mixture of CO + H2 is used in the Fischer-Tropsch reaction to make hydrocarbons in high yields. The reaction requires a catalyst, usually Fe or Ni supported on silica, a temperatue of 200-400°C and a short contact time. Depending on the conditions, aliphatic hydrocarbons, aromatic hydrocarbons, alcohols, and acids can be produced. If NH3 is added to the CO + H2, then amino acids, purines, and pyrimidines can be formed.23 The intermediates in these reactions are not known, but it is likely that HCN is involved together with some of the intermediates postulated for the electric discharge processes. 

Organic chemicals that are susceptible to oxidation and are of concern from the perspective of contamination and environmental degradation include aliphatic and aromatic hydrocarbons, alcohols, aldehydes, and ketones phenols, polyphenols, and hydroquinones sulfides (thiols) and sulfoxides nitriles, amines, and diamines nitrogen and sulfur heterocyclic compounds mono- and di-halogenated aliphatics linear alkybenzene-sulfonate and nonylphenol polyethoxylate surfactants and thiophosphate esters.

Zeolites have been shown to be good adsorbents for H20, NH3, H2S, NO, NOz, S02, and C02, linear and branched hydrocarbons, aromatic hydrocarbons, alcohols, ketones, and other molecules [16,103,104],... 

The study of zeolites as adsorbent materials began in 1938 when Professor Barrer published a series of papers on the adsorptive properties of zeolites [28], In the last 50 years, zeolites, natural and synthetic, have turned out to be one of the most significant materials in modem technology [27-37], Zeolites have been shown to be good adsorbents for H20, NH3, H2S, NO, N02, S02, C02, linear and branched hydrocarbons, aromatic hydrocarbons, alcohols, ketones, and other molecules [2,31,34], Adsorption is not only an industrial application of zeolites but also a powerful means of characterizing these materials [1-11], since the adsorption of a specific molecule gives information about the microporous volume, the mesoporous area and volume, the size of the pores, the energetics of adsorption, and molecular transport. 

Excited states of iminium ion functional groups have been shown to undergo one electron reduction readily from a number of unlikely one electron donors such as simple olefins, aromatic hydrocarbons, alcohols and ethers. PET reaction from these systems have led to the development of synthetically important carbon-carbon bond forming methodology. A number of studies... 

Pesticides used around the house and garden include insecticides, herbicides, rodenticides, fungicides, and fumigants. Toxic chemicals contained in pesticides include organochlorine and organophosphate compounds, carbamates, and arsenicals. The solvents used as carriers for these include aliphatic and aromatic hydrocarbons, alcohols, and glycol ethers. I34l... 

Most paints used in the household today are water-based products. Significant quantities of paints, primers, and brush cleaners are washed down the drain during cleanup following painting. Water-based paints contain numerous toxic chemicals. These include pigments (many with heavy metals), biocides, glycol ethers, binders, amines, acrylate, and other polymer monomers, surfactants, aliphatic and aromatic hydrocarbons alcohols, ketones, and esters. I36,37 ... 

Numerous neurotoxic chemicals have been identified. These include pesticides (particularly, but not limited to, organophosphates and carbamates), aliphatic and aromatic hydrocarbons, alcohols, ethers, ketones, heavy metals (including lead, mercury, manganese, and others), and mixtures of these. Hundreds of individual chemicals are established or suspected neurotoxins. The EPA Guidelines for Neurotoxicity Risk Assessment and the Scorecard list of neurotoxicantsl5 contain partial lists of neurotoxic chemicals. The actual number of chemicals with neurotoxic potential has been estimated to range between 3% and 28% of all the approximately 80,000 chemicals in use (2400-22,400) Clearly, the number of mixtures possible is infinite, though little attention has been devoted to the neurotoxic effects of mixtures. 

Much qualitative and quantitative information about the neurotoxic effects of exposures to organic solvents has been gathered from studies on paintersJ86-95 Solvent-based paints typically contain aliphatic and aromatic hydrocarbons, alcohols, ketones, and esters. A partial, but representative, list of these and their K)w values are given in Table 18.4. As can be seen from this list, a number of lipophilic and hydrophilic chemicals are present in almost all paints.
