Soda lye

Because of thek flash pokits, nitroparaftins are classified as flammable Hquids under DOT regulations (ha2ard class 3, PG III). Nitromethane and nitroethane tires can be extinguished with water, CO2, foam, or class ABC dry chemical extinguishers. Nitroparaftins should not be exposed to dry caustic soda, lye, or similar alkaline materials.

IE) Obtaining [3-l6-Methoxy-2-Naphthylj]2,2-Dimethyi Pentanoic Acid 2.5 g of the previous ester are saponified by means of 15 cc of soda lye and 25 cc of methyl glycol. 

Sodium hydroxide (NaOFI), also called lye, soda lye, or caustic soda to distinguish it from potassium hydroxide (potash lye), is another important base. Flistorically, lye was obtained from the ashes of wood and used to make soap. Lye, however, is an extremely caustic chemical. It can cause serious chemical burns if it comes into contact with the skin and permanent blindness if it gets into the eyes. People had to be very careful while making the soap. They also had to make sure they got the mixture of lye and animal fat (lard) correct to keep from hurting themselves and their families. Because of its caustic (corrosive) nature, sodium hydroxide is also used as the active ingredient in oven and drain cleaners. 

A. G. Labarraque 4 prepared the corresponding chlorinated soda by saturating soda lye with chlorine, and this was called eau de Labarraque. The term eau de Javelle is now often applied to both liquids. 

A. J. Balard 6 prepared a soln. of sodium hypobromite, NaOBr, by working in a similar manner to the process employed for the hypochlorite. When bromine is gradually added to soda lye, the bleaching power increases up to a maximum, and after that decreases owing to the conversion of the hypobromite into bromate. A. J. Balard also described a similar product, potassium hypobromite, obtained by the action of bromine on potassium carbonate. 

According to H. Biltz, ammonia acts energetically on phosphorus pentoxide at ordinary temp., forming a dark reddish-brown mass of phosphamic acid, which, when treated with water, forms phosphine, yellow phosphorus, and a reddish flocculent mass of phosphorus tetritoxide—not red phosphorus as H. S chill supposed. A 0-06 per cent, yield of the same oxide was formed by heating phosphorus pentoxide at 250° either in vacuo or in a current of air, carbon dioxide, hydrogen, oxygen, or steam. Traces were also produced by dissolving the pentoxide in water or soda-lye. 

In 1 L of water there is dissolved 116.0 g (1 mole) of N,N-diethylethylenediamine and, under vigorous stirring at a temperature maintained below 50°C, there is added 205.0 g (1 mole) of the chloride of p-chlorphenoxyacetic acid. The solution becomes rapidly homogeneous the formation of the basic amide hydrochloride is rapidly completed by further stirring the reaction mixture for 2 h at about 20°C. Then an excess of soda lye is added and the basic amide formed is extracted by ether. The ethereal solution is dried on anhydrous sodium sulfate and ether is distilled after that the residue is dried. So 2-(p-chlorophenoxy)-N-(2-(diethylamino)ethyl) acetamide is obtained.
