, sulfur trioxide and a small amount of chlorine gas are generated in the production process. Generally, a high-efficiency absorption tower is used to absorb hydrogen chloride with water to prepare hydrochloric acid; Sulfur dioxide and sulfur trioxide are absorbed with concentrated sulfuric acid....
Complex chemical reaction and heat generation that occur in the liquid phase determine the amount of sulfur trioxide released above a pool of liquid. The sulfur trioxide or CSA vapors then react instantaneously with the moisture in the atmosphere generating sulfuric acid and/or HCl and heat. Water...
A number of derivatives have been prepared from 3, by reaction with nitrogen nucleophiles. Benzalpinacolone (5). which precludes enolisation-a key step in the conversion of 1 into 3, was also converted into 3 on treatment with an excess of chlorosulfonic acid. The identity of the product ...
The meaning of CHLOROSULFONIC ACID is a colorless fuming corrosive liquid ClSO3H made usually by reaction of gaseous hydrogen chloride with sulfur trioxide and used chiefly in organic synthesis (as of sulfa drugs, saccharin, and sulfonic acids).
Freshly prepared benzalacetone (1) can be converted into styrene-4,-disulfonyl dichloride (3) on treatment with an excess of chlorosulfonic acid. The yield... RJ Cremlyn,FJ Swinbourne,PA Carter,... - 《Phosphorus & Sulfur & the Related Elements》 被引量: 14发表: 1990年 The Reaction of...
Chlorosulfonic acidsubstituted benzils2-arylbenzofuran derivativesThe chlorosulfonation of a number of unsymmetrical benzils gave substituted benzofurans. Ring closure is dependent upon the electronic character of the substituent groups and can be controlled by electron-withdrawing groups. The reaction of ...
The materials under study were systems obtained as a result of the reaction of chlorosulfonic acid with the following supports: SiO2, Al2O3, TiO2 and MgO. The selection of such supports with very different acid–base properties should enable the determination of the influence of the...
