NaCI solution

The solvent is then washed 3 x 50mL dH20 and, if desired, can be washed once with lOOmL saturated NaCI solution. Finally, the solvent is dried through Na2S04, removed by vacuum distillation, and the first 5 to 10mL of oil that distills over is saved because it is isomerized safrole (iososafrole), which is suitable for reuse. The rest of the oil that comes over will be the ever lovely MD-P2P, which is perfectly suitable for amination by any method given in this book. 

It was then stirred and refluxed for 8 hours. About 400 ml of methanol was distilled out and the remaining solution was evaporated to about one-third its original volume in vacuo and poured into ice water. This mixture was extracted twice with ether, acidified with 6N HCI, and again extracted with ether. The ether extracts were combined, washed with saturated NaCI solution, dried over anhydrous sodium sulfate, and evaporated in vacuo. The residual oil was distilled through a 15 cm Vigreux column, yielding 666 grams of a-methyl-3-phenoxybenzyl alcohol, BP 132° to 134°C (0.35 mm), no = 1.5809. 

Later work on aluminium alloys has also focused more closely upon the role of hydrogen which had not previously been widely considered as an embrittling species in the stress-corrosion cracking process for these alloys. The idea was not new, however. Reports of intergranular failure under cathodic charging conditions had been made at a much earlier time . A reduction in stress-corrosion life and alloy ductility in a high purity Al-5Zn-3Mg alloy had been found in specimens pre-exposed to a 2% NaCI solution" , an effect that was accentuated if specimens were stressed". ...

The steady-state dissolution rate of chrysotile in 0.1m NaCI solutions was measured at 22°C and pH ranging from 2 to 8. Dissolution experiments were performed in a continuously stirred flowthrough reactor with the input solutions pre-equilibrated with atmospheric concentrations of C02. Both magnesium and silicon steady-state fluxes from the chrysotile surface were regressed and the following empirical relationships were obtained ... 

To further understand and characterise the oxide deactivation process, a.c. impedance studies were carried out, primarily with a 30 at.% Ru/Ti electrode, at various stages during deactivation. These data were compared to those obtained for freshly formed Ru/Ti oxide films, ranging in Ru content from 5 to 40 at.%. Impedance data were collected at the oxide OCP (approximately 0.9 V versus SCE) in fresh NaCI solutions. Under these conditions, no chlorine reactions can occur and the OCP is defined by the equilibria of the redox states on the Ru oxide surface. Deactivation was generally accomplished by square-wave potential cycling, using overpotentials versus the chlorine/chloride potential of 1.59 to — 0.08 V (60 s cycle-1) in 5 M NaCI + 0.1 M HC1 solutions at room temperature.

If, however, the viscosity is measured at the same concentrations in 1 N NaCI solution the behavior is identical with that for non-electrolyte polymers. It is best to proceed as follows. 30 g of NaCI are dissolved in water and made up to 100 ml in a graduated flask this solution is 5.1 normal.To prepare the solutions for measurement at the aforementioned concentrations, the required amounts of poly(methacrylic acid) are weighed into 10-ml graduated flasks, dissolved in about 5 ml of water,and 2 ml of the 5.1 N NaCI solution added.The solutions are finally made up to the mark with water to give a solution of 1 N with respect to NaCI.
