sulfonic การใช้

• Thioflavin S results from the methylation of dehydrothiotoluidine with sulfonic acid.
• Perfluorinated carboxylic acids and sulfonic acids are produced in this way.
• Unlike sulfuric acid itself, sulfonic acids can be solids.
• As with other sulfonic acids, TsOH is a strong organic acid.
• More aggressive oxidants convert cysteine to the corresponding sulfinic acid and sulfonic acid.
• The structure of sulfonic acids is illustrated by the prototype, methanesulfonic acid.
• Its sulfonic acid has been detected in the urine of horses and humans.
• Sulfonic acids, which are organic oxyacids, are a class of strong acids.
• Under oxidative environment, SPES can undergo sulfonic group detachment and main chain scission.
• It is also known as chlorosulfonic acid, being the sulfonic acid of chlorine.
• Reaction of the trialkylborane with hydroxylamine-O-sulfonic acid produces primary benzylamines.
• This sulfonic acid is a precursor to allura red AC, a red food coloring.
• Diazonaphthoquinone sulfonic acid esters are commonly used as components of photoresist materials for semiconductor manufacturing.
• For carboxylic and sulfonic acids, the products are the corresponding acyl and sulfonyl fluorides.
• The sulfonic acid derivative, trifluoromethanesulfonic acid, is comparable in strength to perchloric acid.
• To form a hydrotrope, an aromatic hydrocarbon solvent is sulfonated creating an aromatic sulfonic acid.
• In these dyes, the 2-sulfonic acid group is replaced by H and Cl, respectively.
• Numerous sulfonic acid derivatives of 2-naphthylamine are used in commerce, such as precursors to dyes.
• The principal synthesis entailed oxidation of anthraquinone-2-sulfonic acid with sodium nitrate in concentrated sodium hydroxide.
• For example, 3-bromocamphor-8-sulfonic acid was used in the synthesis of enantiopure devazepide.
