OBA 363 - Names and Identifiers
OBA 363 - Introduction
Fluorescent Brightener 363(Fluorescent Brightener 363) is a chemical used to whiten and whiten fabrics. The following is a description of the nature, use, preparation and safety information of fluorescent whitening agent 363:
Nature:
fluorescent whitening agent 363 is an organic compound, chemical name is stilbene fluorescent whitening agent. It is a white crystalline powder with good solubility and thermal stability. Sensitive to light, it can absorb ultraviolet light and emit fluorescence in blue light, making white fabrics look brighter and whiter under ultraviolet light.
Use:
Fluorescent brighteners are 363 widely used in the textile industry, especially for whitening cotton yarn, hemp yarn, wool fabric, polyester fiber and blended fabric. It can effectively absorb short-wave radiation from ultraviolet rays, and then emit long-wavelength light with blue-white fluorescence, making the fabric look brighter and whiter.
Method:
The fluorescent whitening agent 363 can be obtained by chemical synthesis. The specific preparation method includes imidization reaction between acetophenone and aromatic aldehyde, followed by purification by reduction and crystallization to obtain the final product.
Safety Information:
The fluorescent whitening agent 363 is relatively safe under normal use. However, as a chemical substance, pay attention to the following points when using it: avoid inhaling dust or contact with skin and eyes, and wear appropriate protective equipment if necessary; if you accidentally breathe or come into contact with the fluorescent whitening agent 363, clean the affected area immediately and seek medical help.
