Hooker Electrochemical Company

The submitters used thionyl chloride from Hooker Electrochemical Company. It was distilled and collected over a 1° range (78-79°). The first few drops of thionyl chloride are added cautiously as the initial reaction may be quite vigorous. Recovered thionyl chloride may be used for subsequent runs. 

Pemert A process for making perchloric acid by reacting sodium perchlorate with hydrochloric acid. Invented by J. C. Pemert in 1946 and operated by the Hooker Electrochemical Company at Niagara Falls. 

The submitters used Eastman Kodak Company white label thionyl chloride. The checkers purified commercial thionyl chloride (Hooker Electrochemical Company, refined grade) by the method of Cottle.3... 

Merck s reagent grade of sodium sulfide nonahydrate was used. Since sodium sulfide decomposes on contact with air, a freshly opened bottle should be employed. Sodium Sulfhy-drate (Hooker Electrochemical Company hydrated sodium hydrosulfide) is also satisfactory the amount should be based upon the formula NaHS 2H20, and an equivalent amount of sodium hydroxide in excess of the 27 g. is required. 

A semicommerdal plant based on this process was built and operated for the Manhattan I oject by the Standard Oil Company of Indiana [C4]. In 1953, the U.S. Atomic Energy Commission authorized construction of a larger plant at Niagara Falls, New York, with the Hooker Electrochemical Company as operating contractor [M3]. This plant produced 460 kg/year of B at an enrichment of 92 a/o B. The plant was shut down in January 1958. Eagle Picher Industries, Inc., has been producing 6 at Quapaw, Oklahoma, by this process since 1973 and is expanding capacity to 1000 kg/year. The cost is from 5 to 15/g. 

A schematic diagram of the water-absorption process for recovering chlorine from caustic-chlorine process sniff gas developed by the Hooker Electrochemical Company (Anon., 1957) is. shown in Figure 6-21. In this process, chlorine-containing noncondensable gas from the liquefaction stage of chlorine manufacture is scrubbed countercurrently with water in a packed absorber. The resulting chlorine-free gas can be vented to the atmosphere, and the...

Pardee (Dow Chemical Company), Henry Wigglesworth (National Aniline Chemical Company), Henry B. Rust (Koppers Company), Irenee du Pont (E. I. du Pont de Nemours Company), E. H. Killheffer (Newport Company), E. C. Klipstein (E. C. Klipstein Sons), Samuel Isermann (Van Dyk Company), and Herman A. Metz (Consolidated Color Chemical Company) in Senate Committee on Finance, Hearings, Dyestuffs (1920), 61-141, 155-83, 207-16, 281-326.
