Hyroxides

The reaction between ethyl acetate (A) and aqueous sodium hyroxide (B) (present in slight excess) was followed by withdrawing 10 cc samples of the reaction mixture, pipetting into an excess of 0.01 N HC1 and back titrating the excess acid with alkali. The tabulated results are of the volume, V, of 0.01 N acid necessary to neutralize the NaOH in 10 cc of reaction mixture at the time, sec, shown. The rate equation is to be found.

Dissolve 9 3 S of aniline in 30 cc of cone, hydrochloric acid and 100 cc of water. Then pieces of ice are added to the solution to reduce the temperature to 0°C. Prepare sodium nitrite solution by adding 7 2 g of sodium nitrite to 35 cc of water. Add this solution to the aniline solution slowly, and diazotization occurs. Test the solution with potassium iodide starch papers, to avoid excess of sodium nitrite solution. The point is determined by the colour change of the test paper to a slight blue. Add pieces of ice to the solution during the diazotization to keep the temperature at about 5 C. On the other hand, dissolve 15 g of sodium hyroxide in 200 cc of water and then dissolve g of fi naphthol in this...

NO2—SO2 Absorption by Hydroxides and Carbonates. Several metal hyroxide slurries were screened for NO2-SO2 scrubbing potential. In addition a limestone (CaCOa) slurry was investigated. Magnesia, lime, and limestone scrubbing systems are under consideration for SO2 scrubbing, so our results on the combined scrubbing are pertinent. A summary of the data is contained in Table VI. 

The properties of the membrane hydrolyzed with 10 % sodium hyroxide were measured, and a saturated sodium chloride solution was electrolyzed using this membrane. The results are given in Table I. For comparison, the sulfonyl chloride-type membrane was treated in n-butyl alcohol at 110 °C for 3 hours without introducing air. The treated membrane was subjected to hydrolysis treatment in a methanol solution containing 10 % of sodium hydroxide. Electric resistance of the membrane was 450 —cm, and the current efficiency could not be measured. 

The toxicological information on lithium aluminnm hydride is scant. Becanse it is highly moistnre sensitive, it canses skin bnm on contact with moist skin. Its hydrolysis prodnct lithinm hyroxide is strongly alkaline and corrosive. Ingestion could result in gas embolism dne to hydrogen, which forms readily on reaction with water.
