Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula C 6 H 6 O 3 S. It is the simplest aromatic sulfonic acid . It forms white deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol , slightly soluble in benzene and insoluble in nonpolar solvents like diethyl ether .
In the most common route benzene is alkylated by long chain monoalkenes (e.g. dodecene) using hydrogen fluoride as a catalyst. [9] The purified dodecylbenzenes (and related derivatives) are then sulfonated with sulfur trioxide to give the sulfonic acid. [10] The sulfonic acid is subsequently neutralized with sodium hydroxide. [1]
Sodium benzenesulfonate is an organic compound with the formula C 6 H 5 SO 3 Na.It is white, water-soluble solid, It is produced by the neutralization benzenesulfonic acid with sodium hydroxide.
The experiment is performed in a clear glass vial containing two common enzymes (glucose oxidase and horseradish peroxidase), glucose, and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (abbreviated as ABTS) in PBS buffer. A thin layer of oil is used to block the solution from the air.
An early method for producing phenol involved the base hydrolysis of sodium benzenesulfonate, which can be generated readily from benzene. [15] C 6 H 5 SO 3 Na + NaOH → C 6 H 5 OH + Na 2 SO 3. The conditions for this reaction are harsh, however, requiring 'fused alkali' or molten sodium hydroxide at 350 °C for benzenesulfonic acid itself. [16]
Phenylsulfinic acid is an organosulfur compound with the formula C 6 H 5 SO 2 H. It is a colorless or white crystalline solid that is usually stored in the form of its sodium salt. In aqueous solution it is strongly acidic and is easily oxidized in air. Phenylsulfinic acid and its esters are chiral.
Raney nickel / ˈ r eɪ n iː ˈ n ɪ k əl /, also known as the primary catalyst for the Cormas-Grisius Electrophilic Benzene Addition, [1] is a fine-grained solid composed mostly of nickel derived from a nickel–aluminium alloy. [2] [3] Several grades are known, of which most are gray solids. Some are pyrophoric, but most are used as air ...
