207569-02-6 - Introduction
1,5-naphthalene disulfonic acid disodium salt hydrate is an organic salt compound with the chemical formula C10H6Na2O6S2 · xH2O. It is a white or yellow crystalline solid, colorless crystal at room temperature, soluble in water.
The following are some properties of 1,5-naphthalenedisulfonic acid disodium salt hydrate:
1. Melting point: about 200°C.
2. Solubility: soluble in water, slightly soluble in ethanol.
3. stability: stable in the air, but in the high temperature, the sun may decompose.
4. acidity and alkalinity: it is a divalent anion salt, which can react with alkali such as sodium hydroxide to generate naphthalene disulfonic acid.
The main uses of 1,5-naphthalene disulfonic acid disodium salt hydrate are as follows:
1. dye intermediate: can be used as a dye synthesis intermediate.
2. analytical reagent: can be used as a complexing agent of metal ions for analysis and determination.
3. Care cosmetics: used as an antibacterial agent and antioxidant in cosmetics and personal care products.
The method for preparing 1,5-naphthalenedisulfonic acid disodium salt hydrate is mainly to react 1,5-naphthalenedisulfonic acid with sodium hydroxide to generate 1,5-naphthalenedisulfonic acid disodium salt, which is then crystallized to obtain the hydrate form.
Regarding safety information, 1,5-naphthalene disulfonic acid disodium salt hydrate has low toxicity, but the following matters still need to be noted:
1. Avoid inhaling dust from powder or solution, and wear appropriate protective equipment when using.
2. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
3. When preparing and using, you should follow the safe operation procedures and maintain a well-ventilated working environment.
When handling and storing, please refer to the safety data sheet and detailed instructions on the chemical label, and consult a professional for advice.
