sodium 5-hydroxynaphthalene-1-sulphonate - Introduction
Sodium is an organic compound with the chemical formula C10H7SO3Na. The following is information about the nature, use, preparation and safety of sodium:
Nature:
sodium is a white to pale yellow crystalline solid. It is soluble in water and insoluble in organic solvents. It is unstable under acidic conditions.
Use:
sodium is often used as a reagent and catalyst in organic synthesis. It can be used in the synthesis of dyes, fluorescent agents, polymers and organic metal complexes and other compounds. In addition, it is also widely used in the paper, textile and leather industries.
Preparation Method:
sodium can be prepared by the sulfurization reaction of naphthalene. First, naphthalene and sulfur are reacted under heating to form 1-naphthalene sulfide. The 1-naphthalene sulfide is then converted to sodiumtoo by a redox reaction.
Safety Information:
sodium is relatively safe under general conditions of use. However, it may be irritating to the eyes and skin, so care should be taken to avoid contact with it. Appropriate personal protective equipment, such as gloves and goggles, should be worn during operation. If inhaled or ingested by mistake, seek medical attention immediately. During storage, it should be stored in a dry, well-ventilated place, away from fire and oxidizing agents.
