Solid state synthesis of ring-substituted aminobenzenesulphonic acids

Treatment of 2-methoxyaniline and 3,5-dichloroaniline with conc.H 2SO4 in 2:1 molar ratio at RT affords the corresponding sulphate salts. These salts have been characterized by X-ray diffraction and spectral analyses. Both these salts are found to form ring substituted aminobenzenesulphonic acids in solid state, via proton transfer, under thermal and microwave irradiations.

A study on the sulfonation of aromatic amines with sulfuric acid under microwave irradiation

The sulfonation of aromatic amines with high yields, simple operations and short reaction time has been studied under microwave irradiation in solvent-free conditions.

Sulfonation of arylamines Part 9 - Solid state synthesis of di-ortho ring substituted aminobenzenesulfonic acids

Di-ortho ring substituted arylammonium sulfates (Di-o-RSAS) have been prepared from the corresponding arylamines by treatment with conc. H2SO4 and characterized by elemental, gravimetric and spectral analyses. These sulfates yield the corresponding ring substituted aminobenzenesulfonic acids (RSABSA) when subjected to thermal energy. Non-isothermal gravimetric studies on di-o-RSAS support the formation of RSABSA. It is observed that most of the salts undergo transformation to acid in solid state via proton transfer reaction prior to sulfonation.

Alkanol substituted disazo orange dye for nylon

The specification describes a new group of alkanol substituted disazo compounds that are useful in dyeing polyamide textile fibers in orange hues. The new compounds are compatible with several acid blue dyes and several acid red dyes that are commercially important as dyes for nylon. The new compounds are particularly well suited for use as the "yellow" component in trichromatic systems for dying polyamide carpeting and other textiles. The new compounds are relatively inexpensive to make and have outstanding application and fastness properties. Other aspects of the specification are concerned with a method of making the new compounds and with a method of dyeing polyamides with said compounds and to the novel dyed polyamides resulting from the use of the new group of compounds as dyes.
