Hooker Chemical Company
Hooker Chemical Company (or Hooker Electrochemical Company) was an American firm producing chloralkali products from 1903 to 1968. In 1922, bought the S. Wander & Sons Company to sell lye and chlorinated lime. The company became notorious in the 1960s, when residents near its chemical waste site, Love Canal, reported extraordinarily high incidences of leukemia, birth defects, and other injuries. Although Hooker had sold its old chemical waste dump site in 1953, the company was held responsible as a result of a lawsuit thereafter. History Founding Founded in 1903 as "the Development and Funding Company" by Elon Huntington Hooker, of Rochester, NY, the company used the Townsend cell to electrolyse salt into chlorine and sodium hydroxide (NaOH), also known as "caustic soda" and "lye," in a chloralkali process. Elmer Sperry, founder of Sperry Electric, and Leo Baekeland, inventor of Bakelite and Velox photographic paper, consulted Hooker to improve the design of the cell. The com ...

Sodium Sulfhydrate
Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half-neutralization of hydrogen sulfide () with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless. The solid has an odor of owing to hydrolysis by atmospheric moisture. In contrast with sodium sulfide (), which is insoluble in organic solvents, NaSH, being a 1:1 electrolyte, is more soluble. Structure and properties Crystalline NaHS undergoes two phase transitions. At temperatures above 360 K, NaSH adopts the NaCl structure, which implies that the behaves as a spherical anion owing to its rapid rotation, leading to equal occupancy of eight equivalent positions. Below 360 K, a rhombohedral structure forms, and the sweeps out a discoidal shape. Below 114 K, the structure becomes monoclinic. The analogous rubidium and potassium compounds behave similarly. NaSH has a relatively low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacturing Companies Disestablished In 1968
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. ...

Chemical Companies Of The United States
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...

Synopsis The film surveys several waste disposal sites in the United States. Love Canal, New York The documentary begins with the environmental disaster at Love Canal in Niagara Falls, New York. Governor of New York Hugh Carey provided $10 million in funding for residents nearest the canal to leave. The state purchased the houses of some residents. The film features commentary on pollutant-linked birth defects by Dr. Beverly Paigen of the Roswell Park Institute (now the Roswell Park Comprehensive Cancer Center).

Vinyl Ester Resin
Vinyl ester resin, or often just vinyl ester, is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. The "vinyl" groups refer to these ester substituents, which are prone to polymerize and thus an inhibitor is usually added. The diester product is then dissolved in a reactive solvent, such as styrene, to approximately 35–45 percent content by weight. Polymerization is initiated by free radicals, which are generated by UV-irradiation or peroxides. 352px, Bis-GMA a typical "vinyl ester" derived from bisphenol A diglycidyl ether. This thermosetting polymer, thermoset material can be used as an alternative to polyester and epoxy materials as the thermoset polymer matrix in composite materials, where its characteristics, strengths, and bulk cost are intermediate between polyester and epoxy. Vinyl ester has lower resin viscosity (approx. 200 cps) than polyester (approx. 500cps) and epoxy (approx. 900cps). Uses In homebuilt airplanes, the Glas ...

Hexachlorobenzene
Hexachlorobenzene, or perchlorobenzene, is an organochloride with the molecular formula C6Cl6. It is a fungicide formerly used as a seed treatment, especially on wheat to control the fungal disease bunt. It has been banned globally under the Stockholm Convention on Persistent Organic Pollutants. Physical and chemical properties Hexachlorobenzene is a stable, white, crystalline chlorinated hydrocarbon. It is sparingly soluble in organic solvents such as benzene, diethyl ether and alcohol, but practically insoluble in water with no reaction. It reacts violently above 65 °C with dimethyl formamide and has a flash point of 468 °F. It is stable under normal temperatures and pressures. It is combustible but it does not ignite readily. When heated to decomposition, hexachlorobenzene emits highly toxic fumes of hydrochloric acid, other chlorinated compounds (such as phosgene), carbon monoxide, and carbon dioxide. Synthesis Hexachlorobenzene has been made on a laboratory scale since th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thionyl Chloride
Thionyl chloride is an inorganic compound with the chemical formula . It is a moderately volatile, colourless liquid with an unpleasant acrid odour. Thionyl chloride is primarily used as a chlorinating reagent, with approximately per year being produced during the early 1990s, but is occasionally also used as a solvent. It is toxic, reacts with water, and is also listed under the Chemical Weapons Convention as it may be used for the production of chemical weapons. Thionyl chloride is sometimes confused with sulfuryl chloride, , but the properties of these compounds differ significantly. Sulfuryl chloride is a source of chlorine whereas thionyl chloride is a source of chloride ions. Production The major industrial synthesis involves the reaction of sulfur trioxide and sulfur dichloride: This synthesis can be adapted to the laboratory by heating oleum to slowly distill the sulfur trioxide into a cooled flask of sulfur dichloride. :SO3 + SCl2 -> SOCl2 + SO2 Other methods includ ...

Arsenic Trichloride
Arsenic trichloride is an inorganic compound with the formula AsCl3, also known as arsenous chloride or butter of arsenic. This poisonous oil is colourless, although impure samples may appear yellow. It is an intermediate in the manufacture of organoarsenic compounds.Sabina C. Grund, Kunibert Hanusch, Hans Uwe Wolf "Arsenic and Arsenic Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry'', VCH-Wiley, 2008, Weinheim. Structure AsCl3 is a pyramidal molecule with C3v symmetry. The As-Cl bond is 2.161 Å and the angle Cl-As-Cl is 98° 25'±30. AsCl3 has four normal modes of vibration: ν1(A1) 416, ν2(A1) 192, ν3 393, and ν4(E) 152 cm−1. Synthesis This colourless liquid is prepared by treatment of arsenic(III) oxide with hydrogen chloride followed by distillation: : As2O3 + 6 HCl → 2 AsCl3 + 3 H2O It can also be prepared by chlorination of arsenic at 80–85 °C, but this method requires elemental arsenic. : 2 As + 3 Cl2 → 2 AsCl3 Arsenic tr ...
