GENERAL DESCRIPTION & APPLICATIONS
Naphthols are either of two crystalline monohydric alcohols, derived from naphthalene and belong to the phenol family. There are position isomers; alpha-naphthol (also called 1-naphthol) is 1-hydroxynaphthalene and beta-naphthol (also called 2-naphthol) is 2-hydroxynaphthalene. The compound 1-naphthol is made by heating 1-naphthalenesulfonic acid with caustic alkali or by heating 1-naphthylamine with water under pressure. The compound 2-naphthol is manufactured by fusing 2-naphthalenesulfonic acid with caustic soda. The different positions provide various chemical structures which offer important roles to each characteristic colours. Naphthols are slightly soluble in water but readily soluble in short alcohols, ethers chlorinated solvents, and caustic alkalis. They are used directly in making several dyes and are converted into numerous corresponding amines, esters, ethers and carboxylic derivatives as well as into numerous sulfo- and nitro-group substituted (mono-, di- and tri) naphthol compounds. They find extensive applications in making dyes, pigments, fluorescent whiteners, tanning agents, antioxidants, and antiseptics. Naphthol structure is found as a ligand in transition-metal catalysts particularly in the form of  binaphthol (binol) which is composed of two naphthol rings connected at one carbon site on each ring. Optically active binol is widely used in asymmetric synthesis of rearrangements, epoxidations, reductions.

Sultone is an internal cyclic monoester (anhydride) derived from the hydroxyl and sulfonic radicals, with the formula -OSO2-.in a ring system. It is an analogous to lactone.

Sultone Sultam

Sultam (a cyclic amide) is the nitrogen analog of sultone. Cyclic sulfur structure and analogues are important nucleuses in pharmacological activity and in printing textile materials. Sultone is used as a chemical intermediate to introduce cyclic sulfo groups into target molecules and to provide water affinity and anionic character.
