What is sodium salicylate?

The organic compound sodium salicylate has the chemical formula C7H5O3Na, is odorless, has white scales or powder, and becomes pink when exposed to lengthy periods of light. Insoluble in ether, chloroform, benzene, and other organic solvents; soluble in water and glycerol. burning in a fire. mostly employed in the rheumatology field and organic synthesis. Salicylic acid with alkali neutralization can crystallize.

A sodium salt of salicylic acid is sodium salicylate. Carbon dioxide and sodium phenolate can be combined to make it at greater pressures and temperatures. In the past, it was produced by reacting methyl salicylate, which may be found in wintergreen plants or the bark of delicious birch trees, with an excessive amount of sodium hydroxide and heating it at reflux.

Uses

It is employed as an analgesic and an antipyretic in medicine. In addition to acting as a non-steroidal anti-inflammatory medicine (NSAID), sodium salicylate also promotes necrosis and death in cancer cells. For those who react negatively to aspirin, it may potentially serve as a substitute. In order to detect electrons and vacuum ultraviolet light, it can also be employed as a phosphor. Paste, mucilage, adhesive, and hide preservation agent.

Preparation method

1.Salicylic acid reacts with sodium bicarbonate

When adding ethylenediaminetetraacetic acid (EDTA) and safe powder, salicylic acid and sodium bicarbonate were transferred to distilled water for acidic treatment at 60°C. Heat to 85 °C and then react for 30 minutes. At 85°C, sodium salicylate was produced by drying the qualifying reaction solution in a boiling bed.

2.Phenol method (industrial preparation)

The most common industrial method for making salicylic acid involves using phenol as the initial raw material, reacting it with sodium hydroxide to create sodium phenol solution, adding toluene to the solution to make it the lowest constant boiling substance with water, and then heating the reflux reaction to produce anhydrous phenol sodium. To create sodium salicylate, the latter is under pressure and carboxylated with carbon dioxide.

Operational disposal and storage

Local exhaust air, closed operation. Avoid letting dust into the workshop's air. Operators must get specialized training and adhere to the operating protocols to the letter. Operators are advised to put on self-priming filter dust masks, chemical safety protection eyewear, penetration-proof clothing resistant to poisons, and rubber gloves. Avoid heat and fire sources, and smoking is not permitted in the workplace.

Utilize equipment and a ventilation system that are explosion-proof. Avoid making dust. Keep your distance from alkalis and oxidizers. equipped with a sufficient range and number of firefighting tools and leak emergency treatment tools. Hazardous compounds might still be present in the empty container.

To prevent direct sunlight, sodium salicylate should be stored in a cold, ventilated warehouse, away from heat sources and flames, with the package sealed. Avoid mixed storage and keep sodium salicylate far from oxidants and alkalis. equipped with a sufficient range and number of firefighting tools. An appropriate substance for the leakage must be installed in the storage space.
