isodium,naphthalene-1,5-disulfonate,dihydrate - Introduction
1,5-napthalenedisulfonic ACID DISODIUM SALT, DIHYDRATE is an organic compound with the chemical formula C10H6Na2O7S2 · 2H2O. The following is a description of the nature, use, method and safety information:
Nature:
1,5-napthalenedisulfonic ACID DISODIUM SALT, DIHYDRATE is a colorless crystalline solid, soluble in water and some polar organic solvents. It has strong acidity and is a dibasic acid. The two sulfonic acid groups in the compound are attached to the naphthalene ring at the 1 and 5 positions, respectively.
Use:
1,5-napthalenedisulfonic ACID DISODIUM SALT, DIHYDRATE can be used as an intermediate for dyes and pigments. It is often used in dye applications as an important component of acid dyes. The compounds are used in the dye industry to produce dyes of various colors, such as yellow and orange dyes. In addition, it can also be used to prepare catalysts and catalysts for organic synthesis.
Method:
1,5-napthalenedisulfonic ACID DISODIUM SALT, DIHYDRATE is usually prepared by the reaction of 1,5-naphthalenedisulfonic ACID and sodium hydroxide. First, 1,5-naphthalenedisulfonic acid is reacted with sodium hydroxide under appropriate conditions to generate 1,5-naphthalenediphenol, which is then reacted with sulfur dioxide and finally reacted with sodium hydroxide to obtain the target product.
Safety Information:
1,5-napthalenedisulfonic ACID SALT, DIHYDRATE is relatively safe for human body and environment under normal conditions. However, as a strong acid, it may cause irritation and corrosion to the eyes, skin and respiratory tract. Wear appropriate protective equipment such as chemical gloves and goggles when handling. Also, store the compound in a dry, cool place, away from fire and oxidizing agents.
