TPBi - Introduction
1,3,5-Tris (benzene) is an organic compound, often abbreviated as TABI (triarylbenzidazole). The following is a description of the nature, use, formulation and safety information of TABI:
Nature:
1,3,5-Tris (5-benzene-1) is a white crystalline solid with three benzene rings and three benzimidazole rings in its chemical structure. It has excellent light stability, thermal stability and solubility. The compound can form aggregates in solution and has good luminescence properties. It has high absorption performance in the ultraviolet region, which can effectively block the penetration of ultraviolet rays and protect the stability of the material.
Use:
TABI has a wide range of applications in the fields of chemistry, materials and optoelectronics. It can be added as a fluorescent whitening agent to materials such as plastics, rubber, paints, coatings and fibers to improve the whiteness and brightness of the material. It is also commonly used as a light preservative and light stabilizer to extend the life of plastic and rubber products. In addition, TABI can also be used in optoelectronic devices, Double Layer Capacitors, photovoltaic materials and other fields.
Preparation Method:
There are many synthesis methods of TABI, and a common preparation method is obtained by two-step reaction of acetophenone as the starting material. First, acetophenone is diazotized to give phenylethanol diazotization, and then reacted with 1,3-phthalic dianhydride to give 1,3,5-Tris (benzoxene).
Safety Information:
There is no clear report on the toxicity and safety of TABI. But as a chemical substance, any chemical should follow the correct handling methods and attention points. Appropriate personal protective measures, such as protective gloves, goggles and protective clothing, should be taken when using the compound. At the same time, it should be stored in a dry and cool place to avoid contact with oxygen, strong oxidants or strong acids and bases. If discomfort is caused by accidental application or contact with skin, seek medical attention immediately and take the compound's MSDS (safety data sheet) to the hospital.
