Inventor

Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C₁₄H₁₀, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation.

The invention discloses a method for extracting a plurality of chemicals from a coal tar, which comprises such procedures as heating the coal tar to 120-130 DEG C, dehydrating, fore running, separating, fine rectifying, and heavy-oil distilling, and getting 95 naphthalene, methyl naphthalene, anthracene oil, asphalt and heavy oil. The invention is of simple process, easy operation, rectifies coal tar several times; the extracted chemical products are of steady quality, the naphthalene is of high concentration, and the asphalt is of good quality. The invention is of low energy consumption, hence improves better the added value in processing coal tar in China.

The invention discloses a high water-solubility ruthenium metal complex singlet oxygen fluorescent probe, a preparation method thereof, and an application thereof. According to the invention, a transition metal ruthenium is adopted as a central ion of the ruthenium complex; and anthracene nucleus derivatives with sodium (or potassium) sulfonate groups are adopted as ligands. The ruthenium complex has properties of a singlet oxygen fluorescent probe and a better water-solubility than existing anthracene nucleus derivative ligand ruthenium complexes. The ruthenium complex is suitable for quantitative or qualitative determinations of <1>O2 in neutral or basic system solutions.
