Fluorescent Brightener 52 - Introduction
Fluorescent whitening agent 52, also known as white fluorescein, is a widely used fluorescent whitening agent. The following is a description of its nature, use, preparation and safety information:
Nature:
Fluorescent Brightener 52 is a white crystalline powder, insoluble in water, soluble in organic solvents. It is extremely sensitive to ultraviolet light, can absorb ultraviolet light, and convert it into visible light, so that the surface of the object has a fluorescent effect.
Use:
fluorescent whitening agent 52 is commonly used in various plastics, fibers, coatings, printing inks and other products to improve its whiteness and brightness. It can emit blue light in visible light, thereby canceling the yellow or gray color of the material, giving people a bright and white feeling.
Preparation Method:
The preparation of fluorescent whitening agent 52 is more complex and is generally obtained by synthetic chemical methods. The specific steps include obtaining the initial compound, and finally obtaining the pure product of the fluorescent whitening agent 52 through a series of reaction and purification steps.
Safety Information:
Fluorescent whitening agent 52 is relatively safe under regular use, but the following matters still need to be paid attention:
1. Avoid contact with skin or inhalation of powder. If contact occurs, rinse with water immediately and seek medical help.
2. when in use should wear appropriate protective clothing and gloves to prevent direct contact.
3. Avoid swallowing and seek medical attention if accidentally swallowed.
4. storage should avoid storage with oxidants, acidic substances, etc., to avoid dangerous reaction.
Generally speaking, the fluorescent whitening agent 52 is a commonly used fluorescent whitening agent, which has the function of improving the brightness and whiteness of an object. When using, you need to pay attention to safe use, avoid contact with the skin, inhalation of powder or ingestion.
