How Do You Find the Density of Ethylene Glycol Solution

Liquid Sorption. If a moist gas is passed through sprays of a liquid sorbent, such as lithium chloride or an ethylene glycol solution, moisture is removed from the air at a rate depending on the vapor pressure difference. This is a function of the absorbent concentration and is maintained at the required level by a regeneration cycle. The regeneration process is continuous and is achieved by allowing a percentage of the chemical into the exhaust-heated air. [Pg.724]

Soldered brass seldom gives trouble. In radiators, antifreeze solutions have been alleged to cause corrosion, possibly because materials such as ethylene glycol sometimes detach protective deposits. Sodium nitrite, valuable as a corrosion inhibitor for other metals in a radiator, tends to attack solders, but sodium benzoate is safe and, in addition, protects the soldered joint against the action of nitrites. In an investigation of other inhibitors in ethylene glycol solutions, 1% borax, either alone or in combination with 0-1% mercaptobenzothiazole, appeared to be satisfactory. [Pg.807]

Thin films of ternary cadmium sulfoselenide CdS Sei-x have been electrodeposited from a non-aqueous organic bath by Baranski et al. [67], as well as by Loutfy and Ng [121], who employed similar principles (deposition from ethylene glycol solution... [Pg.106]

Contact of aqueous ethylene glycol solutions with d.c.-energised silvered copper wires causes ignition of the latter. Bare copper or nickel- or tin-plated wires were inert and silver-plated wire can be made so by adding benzotriazole as a metal deactivator to the coolant solution [1], This problem of electrical connector fires in aircraft has been studied in detail to identify the significant factors [2],...

Nicholson and Pizzarello.35"40 Collins and Schiffrin s Lu(Pc)2 was initially studied as a film immersed in aqueous electrolyte, but hydroxide ion from water causes gradual film destruction, attacking nitrogens of the Pc ring.33 Acidic solution allows a greater number of stable write-erase cycles, up to 5 x 106 cycles in sulfuric acid 33 Lu(Pc)2 films in ethylene glycol solution were found to be more stable 34...

In order to obtain information on the electron relaxation time in copper aqua ion, measurements should not be performed in water solution, because the correlation time for proton relaxation is in that case the reorientational time, which is much smaller than T g. NMRD profiles should be actually acquired in ethylene glycol solution and at temperatures lower that room temperature, so that the reorientational time increases one two orders of magnitude (see Section II.B). In this way T e of the order of 10 s can be estimated. [Pg.120]

Recently, Japaridze etal. [170] have investigated adsorption of some aromatic compounds, including naphthalene, naphthonitrile, naphthylamine, anthracene, and phenathrene at the mercury electrode I ethylene glycol solution interface. The analysis of the differential capacity data obtained at the HMDE has revealed that adsorption of the above-mentioned compounds obeys the Frumkin model, with attractive interactions of the particles in the adsorption layer. The results for ethylene glycol were compared with those for other nonaqueous solvents and their role in determining the adsorption mode was discussed. [Pg.982]

Anthracene can be selectively oxidized to anthraquinone by molecular oxygen in the presence of copper(II) bromide in an ethylene glycol solution. Ethylene glycol (EG) acts as a bidendate ligand for copper and prevents the formation of bromoanthracene as a by-product (equation 267).596... [Pg.391]
