Sulfurous acid is commonly known to not exist in its free state, and due to this, it is stated in textbooks that it cannot be isolated in the water-free form. [4] However, the molecule has been detected in the gas phase in 1988 by the dissociative ionization of diethyl sulfite. [5]
A space-filling model of the sulfite anion. Sulfites or sulphites are compounds that contain the sulfite ion (systematic name: sulfate(IV) ion), SO 2− 3. The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used.
Examples of such procedures are described for benzaldehyde, [9] 2-tetralone, [10] citral, [11] the ethyl ester of pyruvic acid [12] and glyoxal. [13] In the ring-expansion reaction of cyclohexanone with diazald , the bisulfite reaction is reported to allow differentiation between the primary reaction product cycloheptanone and the main ...
The sulfoxylate anion (SO 2− 2) The thiosulfate anion (S 2 O 2− 3) Sodium thiosulfate, a salt containing the thiosulfate anion; S 2 O 2− 2, a reported sulfur oxyanion. However salts containing S 2 O 2− 2 and HS 2 O − 2 are not well characterized; they would be conjugate bases derived from the parent thiosulfurous acid (H 2 S 2 O 2 ...
By having more than one anion, many more compounds can be made, and properties tuned to desirable values. [3] In terms of optics, properties include phosphorescence, photocatalysis, [4] laser damage threshold, refractive index, birefringence, absorption particularly in the ultraviolet or near infrared, non-linearity. [5]
Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".
Taft is the location of a phosphate processing facility owned by The Mosaic Company (formerly IMC-Agrico); the Dow/Union Carbide Taft/Star Petrochemical Plant, which produces a variety of organic chemicals such as acrolein, acrylic acid, and acetaldehyde; and part of the Waterford Nuclear Generating Station owned by Entergy Corporation.
This is a list of Superfund sites in Louisiana designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.
