FBA 351 - Introduction
Fluorescent brightener CBS(2,2 '-diphenyl sulfoxide) is a white dye widely used in the textile, plastics, detergent and paper industries. The following is an introduction to the nature, use, method and safety information of CBS:
Nature:
-Appearance: Colorless or slightly yellow crystalline powder
-Solubility: well dissolved in common organic solvents
-Thermal stability: stable at high temperature, suitable for the heating treatment process of textiles
-Fluorescent characteristics: It has a good fluorescent whitening effect, which can enhance the whiteness and brightness of the object
Use:
-Textile industry: Fluorescent brightener CBS is commonly used to enhance the whiteness and brightness of textiles to make them look brighter. Suitable for all kinds of fibers, such as cotton, linen, silk, wool, etc.
-Plastic Industry: CBS can be used as a whitening agent for plastic products to improve the brightness and purity of transparent plastic products.
-Detergent industry: As a fluorescent whitening agent in detergent, it can enhance the cleaning effect of washing powder, detergent and other products.
-Paper industry: CBS can provide paper with better whiteness and brightness, making it have a higher visual effect.
Preparation Method:
The preparation method of fluorescent whitening agent CBS is more complicated, usually involving the chemical reaction of acetophenone and sulfuric acid. The specific preparation method involves organic synthesis and fine chemical process, which requires special production and treatment.
Safety Information:
- CBS are low-toxic substances, no fatal harm to the human body.
-Avoid inhaling the powder and avoid contact with skin and eyes to prevent irritation.
-the use of the process should pay attention to protective measures, such as wearing gloves and masks, to ensure good ventilation.
-If taken by mistake or inhaled too much, seek medical attention immediately.
Please note that the above information is for reference. In actual use, relevant safety procedures should be followed and the fluorescent whitening agent should be used with caution.
