ethylenediaminetetraacetic acid*trisodium - Introduction

Ethylenediaminetetraacetic acid trisodium salt dihydrate is a crystal compound, the chemical formula is Na (C10H12N2O8)· 2H2O, colorless crystals at room temperature. It is a chelating agent with strong coordination ability.

EDTA trisodium salt dihydrate is mainly used in industrial production and chelating reagent in laboratory. It can form a stable complex with metal ions, and is often used to prepare buffer solutions, separation and determination of metal ions, and water treatment and other fields.

The preparation of ethylenediaminetetraacetic acid trisodium salt dihydrate can usually be obtained by reacting ethylenediaminetetraacetic acid with sodium hydroxide. First, ethylenediaminetetraacetic acid is dissolved in water, and then sodium hydroxide solution is slowly added. The reaction forms ethylenediaminetetraacetic acid trisodium salt, and finally the dihydrate is obtained by crystallization.

Regarding safety, ethylenediaminetetraacetic acid trisodium salt dihydrate is a relatively safe compound. However, it may have an irritating effect on the eyes, skin and respiratory tract. Wear appropriate protective gloves and safety glasses when using, avoid direct contact. At the same time, avoid inhaling dust and solutions. If accidentally inhaled or contact, should be immediately cleaned, and timely medical treatment. Relevant safety procedures shall be followed during storage and use.
