4,4 '-(1,4-phenylenedimethylidyne)bis[2-phenyloxazol-5(4H)-one], also known as Bisbenzoxazole, has the following characteristics:
1. Appearance: Bisbenzoxazole is a white to light yellow crystal powder.
2. Physical properties: its melting point range of 300-305 ° C, soluble in organic solvents such as Alcohols, Ketones and esters, insoluble in water.
3. Chemical properties: Bisbenzoxazole has optical properties, can be used as fluorescent whitening agent. It has high thermal stability and light stability.
4. Application: Bisbenzoxazole is mainly used in plastics, fibers and coatings and other materials to enhance its whiteness and brightness, and improve its optical performance.
5. Preparation method: A feasible preparation method is to obtain Bisbenzoxazole through the condensation reaction of 2-aminobenzoic acid and acid chloride under acid catalysis.
6. Safety Information: Bisbenzoxazole is relatively safe under normal conditions of use, but it is still necessary to follow general laboratory operating procedures and safety measures. It is less toxic, but direct contact with the skin, eyes and respiratory tract should still be avoided. In case of contact, flush with plenty of water and seek medical attention.
