Among electrolytic processes used to produce materials, we customarily distinguish those in which electrodes are reacting that is, where the metal or other electrode material is involved in the reaction (Chapter 16) from those with nonconsumable electrodes (Chapter 15). A very important industrial process with nonconsumable electrodes is the electrolysis of sodium chloride solution (brine) producing chlorine at the anode and sodium hydroxide NaOH (caustic soda) in the catholyte via the overall reaction... [Pg.321]

In the 250-mL plastic bottle, dissolve about 50 NaOH pellets in 200 mL of distilled water. CAUTION Sodium hydroxide is caustic. [Pg.150]

The unreacted propylene is taken off the top of the reactor and cleaned up for recycling. By bubbling this stream through a dilute caustic solution (like sodium hydroxide, NaOH), the chlorine and HCl carried along with the propylene are removed by converting them to sodium chloride, NaCl, and water. The scrubbed propylene is then taken overhead (from the top of the fractionation column) and is ready as fresh feed or use elsewhere in the plant. [Pg.160]

Sodium hydroxide (NaOH) is one of the most useful industrial sodium compounds. It is also known as lye or caustic soda and is one of the strongest base alkahs (high pH value) on the household market. It is used as a drain and oven cleaner, and it saponifies fats in the manufacture of soap. It must be used with care because it is also capable of producing serious skin burns. [Pg.53]

For the past several centuries, soaps have been prepared by treating animal fats with sodium hydroxide, NaOH, also known as caustic lye. In this reaction, which is still used today, each fat molecule is broken down into three fatty acid soap molecules and one glycerol molecule ... [Pg.241]

CAUSTIC (Chemical). A corrosive substance, almost always of an alkaline nature, such as sodium hydroxide, NaOH potassium hydroxide. KOH or calcium oxide, CaO. Such substances attack many metals, plastics, and other materials, including human tissue, and generally fall in the category of corrosives. [Pg.307]

Sodium hydroxide (NaOH also known as lye or caustic soda), potassium hydroxide (KOH also known as caustic potash), and barium hydroxide [Ba(OH)2] are examples of bases. When any of these compounds dissolves in water, OH anions go into solution along with the corresponding metal cation. Sodium hydroxide and potassium hydroxide provide one OH- ion each, and barium hydroxide provides two OH- ions, as indicated by its formula. [Pg.56]

The electrolytic cell shown in Figure 2 is the industrial chloralkali cell in which brine (an aqueous sodium chloride solution) is electrolytically converted to chlorine and caustic soda (sodium hydroxide, NaOH). The external power source supplies electric energy to drive the overall reaction. [Pg.36]

Chlor-alkali production — With a 63% production volume of the total world chlorine capacity of about 43.4 million tons (in 1998), the chlor-alkali (or chlorine-caustic) industry is one of the largest electrochemical technologies in the world. Chlorine, Cl2, with its main co-product sodium hydroxide, NaOH, has been produced on industrial scale for more than a century by -> electrolysis of brine, a saturated solution of sodium chloride (-> alkali chloride electrolysis). Today, they are among the top ten chemicals produced in the world. Sodium chlorate (NaC103) and sodium hypochlorite (NaOCl, bleach ) are important side products of the... [Pg.94]

Caustic Soda The common name for sodium hydroxide (NaOH). Used as a bleaching chemical. [Pg.15]

SODIUM HYDROXIDE (CAUSTIC SODA) Physical Properties Sodium hydroxide, NaOH, mol wt 39.998, is a brittle, white, translucent crystalline solid. Because of its corrosive action on all human body tissue, it is also known as caustic soda. Physical properties of the pure material are noted in Table 20. Sodium hydroxide is produced and shipped in the anhydrous state in the form of solid cakes, flakes, or beads, but is used in solution (4). Properties of aqueous sodium hydroxide solutions relevant to industrial operations are available from manufacturers and in handbooks (79). Table 21 lists the significant uses. Table 20. Physical Constants of Pure Sodium Hydroxide ... [Pg.511]

Production of aikyibenzene suifonates [1, 2]. The alkylbenzene sulfonates, used as liquid surfactants in making the detergent slurry, are produced by the sulfonation of linear alkylates followed by the neutralization step with a caustic solution containing sodium hydroxide (NaOH).
