Organic compounds, solubility

Benzyl chloride undergoes self-condensation relatively easily at high temperatures or in the presence of trace metallic impurities. The risk of decomposition during distillation is reduced by the use of various additives including lactams (43) and amines (44,45). Lime, sodium carbonate, and triethylamine are used as stabilizers during storage and shipment. Other soluble organic compounds that are reported to function as stabilizers in low concentration include DMF (46), arylamines (47), and triphenylphosphine (48). 

The purpose of the system is to bring the water into contact with the organisms. Then if they find the diet (soluble organic compounds) to their liking they will feast upon it. But just like man, they have other needs besides food.

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. 

Waste water may be difficult to purify sufficiently if it is contaminated with soluble organic compounds. 

The LLE of relatively polar and water-soluble organic compounds is, in general, difficult. The recovery obtained from 11 of water with dichloromethane is 90% for Atrazine but lower for its more polar, degradation products, i.e., di-isopropyl- (16%), di-ethyl- (46%),andhydroxy-atrazine (46%). By carrying out LLE with a mixture of dichloromethane and ethyl acetate with 0.2 mol/1 ammonium formate, the extraction recoveries for the three degradation products were increased to 62 %, 87 %, and 65 %, respectively [437].

An advantage of the CURE process is the ability to achieve high contaminant removal rates. Also, floe, a by-product of the CURE process, tends to be stable and settle rapidly. Electrocoagulation will not remove metals that do not form precipitates. In addition, electrocoagulation will not remove nonreactive, soluble organic compounds nor desalinate water. 

Researchers are interested in this technology because it removes low-solubility organic compounds that are not readily amenable to bioremediation or current pump-and-treat practices. These compounds typically are sorbed onto the naturally occurring organic materials in the soil. This technology has the potential to treat low-solubility organic compounds with minimal generation of secondary waste.

By using Thurman s empirical formula, it was calculated that a column of 45 L of XAD-8 would be required to completely retain these compounds. This size column would require 135 L of solvent for elution. Collecting five samples at once would require a pilot plant for distillation and extraction comparable in magnitude with the water treatment pilot plant being sampled. Therefore, a decision was made to use smaller columns at the risk of losing more soluble organic compounds.
