Thionyl chloride can also be used to convert metal oxides or hydroxides to the chlorides, and it will also react with many organic compounds. Alcohols react as follows ... 

The addition of a small quantity of electrolyte (such as minerals dissolved from adjacent soil particles) increases surface tension. A small quantity of soluble organic compound (alcohol, soap, or acid) decreases the surface tension. The addition of glycerine to water reduces surface tension and thus makes it possible to stretch water him into bubbles, as with a child s bubble-blowing game.

Similarly, the thermodynamic potential for EM of some model organic compounds (alcohols, carboxylic acids, ketenes, phenols, and aromatic acids) can be calculated. Typical values are reported in Table 1.1. This table shows that the thermodynamic potential for EM of organics never exceeds 0.2 V/SHE. 

In VOCs, the major issues concern CH4 and short-chain HCs which are difficult to adsorb selectiviely. Moreover, CH4 is the most abundant HC emission and the most refractory to low cost oxidation. Another problem deals with the removal of hydrophilic organic compounds (alcohol, ketone. ..) in waste water. 

The synthesis of titanium silicates by basic and acidic hydrolysis in an organic-water media were carried out at 80-150 C in an autoclave with stirring (150-200 rpm) at autogenic pressure (2.5-4.5 at.). As silicon sources tetraethoxysilane and silicic acid have been used. As metal sources the metal-organic compounds alcoholates, stearates, acetylacetonates, acetates or mineral salts have been used. Hexamethylenetetramine, N,N-dimethylocteIamine, monoethanolamine were used as the structure-directing agents. 

The group frequency region falls approximately between 4000 to 1400 cm-1, and the absorption bands in it may be assigned to vibration of pairs of two (or sometimes three) atoms. The frequency is characteristic of the masses of the atoms involved and the nature of their bond, ignoring the rest of the molecule. Therefore, IR spectra are useful for determining the presence of functional groups in organic compounds alcohols (—OH), ketones (=CO), amines... 

A second reason for the vast number of organic compounds is that carbon atoms can form stable bonds with other elements. Several families of organic compounds (alcohols, aldehydes, ketones, esters, and ethers) contain oxygen atoms bonded to carbon. Others contain nitrogen, sulfur, or halogens. The presence of these elements confers a wide variety of new chemical and physical properties on an organic compound.

In this framework, the class of lipases is made up of enzymes largely employed in pharmaceutical productions, whose product is specific enantiomeric forms of organic compounds (alcohols, adds, esters, amines). The enantioselective hydrolysis of racemic esters and simultaneous separation of the corresponding optically pure (5)-add as pure isomer is of considerable interest to the pharmaceutical industry as a route to non-steroidal anti-inflammatory drugs. In this field, studies have been devoted to the feasibility analysis of MBRs to produce (5)-ibuprofen esters and acids. Studies related to the modeling of the lipase-catalyzed hydrolysis of (S)-ibuprofen acid in MBRs show the feasibility of EMRs for the stereo-selective production of (S )-ibuprofen add indeed, the model indicates a high effidency of the EMR in the kinetic resolution of racemic solutions. ... 

The use of ultrasound for the destruction of dilute aqueous solutions of low molecular weight organic compounds (alcohols, ketones and aldehydes) at ambient temperature has been reported. An aqueous flow cell system was assembled to measure the oxidatively degraded formate and acetate products by on-line ion chromatography [48]. 

Most starches contain 20-30% amylose (Table 4.24). New corn cultivars (amylomaize) have been developed which contain 50-80% amylose. The amylose can be isolated from starch, e. g., by crystallization of a starch dispersion, usually in the presence of salts (MgS04) or by precipitation with a polar organic compound (alcohols, such as n-butanol, or lower fatty acids, such as caprylic or capric), which forms a complex with amylose and thus enhance its precipitation. 

Solvent A liquid, usually volatile, which is used to reduce viscosity. This is essential in both manufacturing and application processes. Solvents evaporate during application and drying of paint and therefore do not become a part of the dried film. In conventional coatings the solvents are organic compounds (Alcohols, Esters and Ketones) whilst in waterborne systems there is a mix of organic solvents with water.

The first coordination epoxide polymerization catalytic system was reported by Pmitt and Baggett in 1955. It was based on iron tricbloride. Since that time, metal-based catalysts bave been widely exploited for epoxide polymerization. Tbe most studied systems are those based on zinc or aluminum derivatives. A first group consists of diethylzinc or trialkylaluminum associated to a cocatalyst, wbicb is generally water or an organic compound (alcohol, amine, and other compoimds) that reacts with the alkyl metal to form in situ new metal derivatives as the true catalytic system exploited (see Table 6). For a detailed review on the coordination polymerization of epoxides, see Kman. ...
