2-Naphthol[edit | edit source]

2-Naphthol is an organic compound with the chemical formula C10H7OH. It is a white crystalline solid that is commonly used in various industries, including the production of dyes, pharmaceuticals, and pesticides. This article will provide an overview of the properties, uses, and synthesis of 2-Naphthol.

Properties[edit | edit source]

2-Naphthol is a solid at room temperature, with a melting point of approximately 122-123 °C. It has a molecular weight of 144.16 g/mol and a density of 1.23 g/cm³. The compound is sparingly soluble in water but dissolves readily in organic solvents such as ethanol and ether.

Uses[edit | edit source]

2-Naphthol has a wide range of applications in different industries. One of its primary uses is as a precursor in the production of dyes. It is commonly used to synthesize various types of azo dyes, which are widely used in the textile industry for coloring fabrics. Additionally, 2-Naphthol is utilized in the manufacturing of pharmaceuticals, particularly in the synthesis of antiseptics and analgesics.

Furthermore, 2-Naphthol is employed as an intermediate in the production of pesticides. It acts as a key building block in the synthesis of fungicides and herbicides, contributing to the control of plant diseases and weed growth.

Synthesis[edit | edit source]

The synthesis of 2-Naphthol can be achieved through various methods. One common approach involves the oxidation of naphthalene, a polycyclic aromatic hydrocarbon, using a suitable oxidizing agent such as chromic acid or potassium permanganate. This reaction results in the formation of 2-Naphthol as the main product.

Another method involves the hydrolysis of 2-naphthyl acetate, which can be obtained by acetylation of 2-naphthol. The hydrolysis reaction is typically carried out under basic conditions, resulting in the formation of 2-Naphthol.

Safety Considerations[edit | edit source]

2-Naphthol should be handled with care due to its potential health hazards. It is considered toxic if ingested, inhaled, or absorbed through the skin. Direct contact with the compound may cause irritation to the skin, eyes, and respiratory system. Therefore, appropriate protective measures, such as wearing gloves and goggles, should be taken when working with 2-Naphthol.
