Properties and stability
This product can be absorbed through the skin and cause poisoning. Animal test results show that the lowest oral poisoning dose for mice is 20 mg/kg (for one consecutive day). Operators should wear protective equipment.
Storage method
This product should be sealed and stored in a cool, dry place.
Packed in plastic bags lined with woven bags, stored in a cool, dry and ventilated place, protected from sun and moisture, and away from fire and heat sources. Store and transport according to general chemical regulations.
Synthesis method
Made from phenanthrene oxidation, there are chemical methods and electrolysis methods. 1. Chemical method uses sodium (or potassium) dichromate and phenanthrene in sulfuric acid aqueous solution for oxidation. 2. The electrolyte of the electrolytic oxidation method contains 120g/L of chromium trioxide, 450g/L of sulfuric acid, and 35g/L of phenanthrene. The cathode current density is 3.75A/cm2, the electrolyte temperature is 60-65°C, and after 8 hours of electrolysis, the product is filtered.
Purpose
Phenanthrenequinone itself is a pesticide and can be used as a fungicide, seed dressing agent, electrophotography, photoconductive material, photosensitive solder resist and paper preservative.
