What is benzene sulfonic acid used for?
Technical Summary: Benzenesulfonic acid is used for surfactant enhanced oil recovery (SEOR), also known as surfactant flushing. Surfactant use allows for enhanced recovery of large volumes of LNAPL (petroleum hydrocarbons).
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.
What is the formula of benzene sulphonic acid?
C6H6O3S
Benzenesulfonic acid/Formula
What happens when benzene sulphonic acid?
Reactions. 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 toxic?
Chemical dangers This produces toxic and corrosive fumes. The solution in water is a strong acid. It reacts violently with bases and is corrosive. Reacts violently with oxidants.
Is benzenesulfonic acid a carcinogen?
Benzoic acid can become carcinogenic. It is important to know that when sodium benzoate combines with ascorbic acid (vitamin C), it can form a known carcinogen called benzene. “Benzene is among the 20 most widely used chemicals in the United States. We cannot completely avoid exposure to 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.
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.
How do you make benzene from benzene sulphonic acid?
Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. It is important to note that the chemical formula of the sulfonic group is -SO3H. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene.
How do you get benzene from benzene sulphonic acid?
What functional group is benzenesulfonic acid?
carboxylic acid functional
Benzoic acid: Any molecule featuring a carboxylic acid functional group bonded to a benzene ring. Most commonly refers to the parent member of this family, C6H5COOH.
Does gasoline have benzene?
Benzene is also a natural part of crude oil, gasoline, and cigarette smoke. Benzene is widely used in the United States. It ranks in the top 20 chemicals for production volume. Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibers.
