Uses. Salts of Benzenesulfonic acid such as Sodium benzenesulfonate (Ludigol) and Monoethanolamine benzenesulfonate are used as surfactants in laundry detergent. A variety of pharmaceutical drugs are prepared as benzenesulfonate salts and are known as besilates (INN) or besylates (USAN).
What is dodecyl benzene sulphonic acid?
Dodecylbenzene Sulfonic Acid is a thick, light yellow to brown liquid. It is used to make detergents. REASON FOR CITATION. * Dodecylbenzene Sulfonic Acid is on the Hazardous Substance List because it is cited by DOT and EPA. * This chemical is on the Special Health Hazard Substance List because it is CORROSIVE.
Is EAS reversible?
Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene. …

How do you neutralize a Ddbsa?
The preferred procedure for neutralization of DDBSA is to add the formula amount of water into the mixing tank and start mixing. Add the formula amount of sodium hydroxide 50% solution and then slowly add the DDBSA.
What does hno3 and h2so4 do?
Sulfuric acid protonates nitric acid to form the nitronium ion (water molecule is lost). The nitronium ion is a very good electrophile and is open to attack by benzene. Without sulfuric acid the reaction would not occur.
How do you make benzene sulphonic acid?
To produce benzenesulfonic acid from benzene, fuming sulfuric acid and sulfur trioxide are added. Fuming sulfuric acid, also refered to as oleum, is a concentrated solution of dissolved sulfur trioxide in sulfuric acid.
What happens when benzene sulphonic acid is heated?
Sulphonation is a reversible reaction. However, when benzenesulphonic acid is heated with excess of steam , the reaction moves in the backward direction giving benzene and H2SO4.
Is benzenesulfonic acid a surfactant?
Use Summary: Alkyl (C8’C24) benzenesulfonic acid and its ammonium, calcium, magnesium, potassium, sodium, and zinc salts are surfactants with a wide variety of manufacturing uses.
What is the chemical name for alkyl benzenesulfonic acid?
Chemical: Alkyl (C8-C24) benzenesulfonic acid and its ammonium, calcium, magnesium, potassium, sodium, and zinc salts (see Table 1). Page 1 of 74 Table 1. Tolerance Exemptions for Alkyl (C8’CZ4) Benzenesulfonic Acid and its Ammonium, Calcium, Magnesium, Potassium, Sodium, and Zinc salts 40 CFR 180
How do you make benzenesulfonic acid anhydride?
Benzenesulfonic acid exhibits the reactions typical of other aromatic sulfonic acids, forming sulfonamides, sulfonyl chloride, and esters. The sulfonation is reversed above 220 °C. Dehydration with phosphorus pentoxide gives benzenesulfonic acid anhydride ((C6H5SO2)2O).
Is benzenesulfonic acid biodegradable?
Benzenesulfonic acid is biodegradable and does not degrade into benzene(the benzene ring breaks down first). The surfactant is low in toxicity (LD50 >2000 mg/kg). USEPA has determined that Benzenesulfonic Acid is a Safer Chemical Ingredient for Surfactant use and meets the criteriaof the Design for the Environment.
