Interaction energies (heats of adsorption) of test compounds on carbosil change in a. sequence characteristic of graphitized blacks [43] with which the compounds interact in a non-specific way q > q°t,B- That is why higher values of a were obtained in case of silica gel. PEG deposition on silica surface, however, causes selectivity decrease whereas the coefficient a increases on carbosil modified with glycol (Table 1). A considerable increase is observed after polyethylene glycol monolayer formation on the complex adsorbent surface. 

Table 7.11 gives the average commercial specifications of propylene glycol Table 7.12 summarizes the uses of this product, as well as figures for production, capacities and consumption in 1984 for Western Europe, the United States and Japan. 

Rate parameters for the reaction of nickel(II) with pyridine, bipyridine, phenanthroline, and terpyridine are available [118] for dimethyl-sulphoxide and acetonitrile solvents along with similar data for terpyridine in methanol and ethylene glycol (Table 12). To test whether or not substitution is normal in type, ligand substitution rate coefficients (fej) are compared with the respective solvent exchange rates (fes) by means of a ratio R defined as...

However it is also established that the commonly used diphenylmethane and naphthalene diisocyanate-based elastomers are frequently chain-extended with glycols. Table 3.12 contrasts the effects of diamine and glycol chain extenders with a toluene diisocyanate/polyether-based prepolymer, Adiprene LI00. With the unsymmetrical diisocyanates, such as TDI and MDI, polyol chain extenders give elastomers of poorer properties than diamines, and it is usually desirable to introduce additional crosslinking into diol-extender elastomers by the use of a proportion of a triol such as... 

An example of increasing the solubility by using co-solvents is a phenobarbital oral solution with ethanol and propylene glycol (Table 5.4). The formula is only suitable for use of limited duration in adults. Both solvents make the solution unsuitable for children. Prolonged use can make the amount of propylene glycol also too high for adults. 

In addition to MA, phthalic anhydride, and ethylene glycol, other common intermediates used for the production of unsaturated polyesters are fumaric acid, isophthalic acid, adipic acid, propylene glycol, diethylene glycol, and dipropylene glycol. Table 12.1 provides a summary of both common and specialty building blocks used in polyesters and contributions made by these intermediates to the properties of the products. Recycled polyethylene terephthalate beverage bottles may one day become an important raw material for unsaturated polyester resin production, providing an alternative for a substantial part of the petroleum-based intermediates. 

Maleic anhydride adducts of anthracene and cyclopentadiene (Fig. 4) were used in the synthesis of UPRs and apphed directly during the polycondensation reaction of maleic anhydride with ethylene glycol or diethylene glycol (Table 7) [17]. 

Ethylene oxide reacts readily with all H-acid compounds, for example an alkyl-phenol, fatty alcohol, fatty acid, fatty acid amide, fatty amine, mercaptan, glycol and poly glycol (Table 2).
