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 .
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.
p-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6] The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos.
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]
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
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.
Sulfanilic acid can be produced by sulfonation of aniline with concentrated sulfuric acid. [5] This proceeds via phenylsulfamic acid; a zwitterion with a N-S bond. Eugen Bamberger originally proposed a mechanism involving a series of intramolecular rearrangements, with phenylsulfamic acid forming orthanilic acid, which rearranged to sulfanilic acid on heating.
reduction of 1-nitroonaphthalene-8-sulfonic acid, precursor to C.I. Acid Blue 113 Notes: Peri-acid dehydrates to the sultam . Via the Bucherer reaction , heating periacid with anilinium salts gives the N-phenyl derivative, precursor to Acid Blue 113.
