What has the author Johannes Klaas Bosscher written?
Johannes Klaas Bosscher has written: 'Kinetics of aromatic sulfonation with sulfur trioxide in nitromethane and trichlorofluoromethane' -- subject- s -: Sulphonation, Sulphur trioxide
How remove sulfate in sulfonation reaction?
In an aromatic sulfonation reaction, a sulfonyl group (-SO3H) replaces a hydrogen on an aromatic ring (such as benzene). This is done by refluxing (heating to boiling with a reflux condenser) the aromatic with fuming sulfuric acid (concentrated sulfuric acid with gaseous SO3 present).This reaction is reversible, so mixing the aryl sulfonic acid with a dilute acid will reform the sulfuric acid and remove the sulfonyl group from the arene.
What is the Sulfonation process to produce dodecyl benzene sulfonic acid?
The sulfonation process to produce dodecyl benzene sulfonic acid involves reacting dodecyl benzene with a sulfonating agent, such as sulfur trioxide or chlorosulfonic acid, to introduce a sulfonic acid group onto the benzene ring. The reaction typically takes place under controlled conditions of temperature and pressure to ensure high yield and purity of the desired product. The dodecyl benzene sulfonic acid produced is an important surfactant used in various industries.
What solid is formed when sulfuric acid is added to PABA?
When sulfuric acid is added to PABA (para-aminobenzoic acid), a white solid known as p-aminobenzoic acid sulfate is formed. This is due to the sulfonation of the amino group on the PABA molecule.
What is formed when aminobenzoic acid reacts with sulfuric acid?
When aminobenzoic acid reacts with sulfuric acid, it can form an amide derivative known as N-acetylanthranilic acid. This reaction involves the sulfonation of the amine group in aminobenzoic acid by sulfuric acid.
How ampicillin synthesised?
Ampicillin is synthesized through a series of chemical reactions starting from a compound called 6-APA (6-aminopenicillanic acid). This compound is modified through acylation, sulfonation, and oxidation steps to produce ampicillin. The final product is then purified and isolated for use as an antibiotic.
When wool is dipped in sulphuric acid what happens?
When wool is dipped in sulphuric acid, it undergoes a process called sulfonation. The acid reacts with the wool fibers, breaking down the protein structure and causing them to dissolve. This process can be used to modify the properties of wool for various industrial applications.
What are the chemicals of making sulphonic acid?
You react oil with Sulphur Trioxide via falling film reactor or react oil with Oleum (very strong Sulphuric Acid) in a CSTR reactor. The name of the process is Sulphonation or Sulfonation depending on English or American spelling style.
What are the Physical and chemical factors of estuary?
Physical factors of estuaries include temperature, salinity, turbidity, and the presence of physical structures like mudflats or marshes. Chemical factors include levels of oxygen, nutrients, pollutants, and pH levels. These factors can vary widely within an estuary due to tidal influences, freshwater input, and interactions between marine and freshwater environments.
What did Erasmus write about in his writings?
Wilhelm Erasmus Arends has written: 'Early piety recommended in the life and death of Christlieb Leberecht von Exter'
What are the potential applications of the compound hoso2cl in the field of organic chemistry?
The compound HOSO2Cl, also known as chlorosulfonic acid, has various potential applications in organic chemistry. It can be used as a reagent for sulfonation reactions, as well as for the synthesis of sulfonic acids and esters. Additionally, it can be employed in the preparation of various organic compounds, such as dyes, pharmaceuticals, and agrochemicals. Its strong acidic nature makes it a versatile tool for introducing sulfonate groups into organic molecules, thereby altering their properties and reactivity.
What happens when toluene reacts with sulfuric acid?
When toluene reacts with sulfuric acid, it undergoes a sulfonation reaction to form benzene sulfonic acid. This reaction involves the substitution of a hydrogen atom in the toluene molecule with a sulfonic acid group (-SO3H). The product obtained is a benzene sulfonic acid derivative, which can be further converted into various organic compounds.
