Product Overview/产品概述:
Phosphorus is an important basic industrial raw material, mainly used in chemical industry, pesticide and other fields.
Product Introduction/产品介绍:
Yellow phosphorus is a colorless waxy crystal with a garlic-like odor. English name: Phosphorus, yellow, molecular formula P4. Molecular weight 124.08. Relative density 1.82 (20°C). Melting point 44.1°C. Boiling point 280°C. Vapor relative density 4.3. Insoluble in water, easily soluble in fats and organic solvents such as carbon disulfide. At room temperature, it can spontaneously combust in the air and is easily oxidized to phosphorus trioxide and phosphorus pentoxide, so it is often stored in water. Yellow phosphorus vapor can be oxidized to hypophosphorous acid and phosphoric acid when it encounters humid air. Light green fluorescence can be seen in the dark.
Since the production of yellow phosphorus consumes a lot of energy and has a great impact on the surrounding environment, it is a high-energy-consuming and high-pollution industry. The production process of yellow phosphorus is relatively simple. Phosphate ore, silica and coke are put into an electric furnace in a certain proportion and particle size. Decomposition and reduction reactions occur at a high temperature of more than 1000 degrees. The phosphorus vapor and furnace dust are cooled and rinsed together to obtain the product, and the high-temperature slag is directly discharged from the electric furnace. Yellow phosphorus is mainly used as a raw material for making red phosphorus, phosphoric acid and phosphorus compounds, and is also used in pesticides, rodenticides, etc. Vigorously develop fine phosphate products using yellow phosphorus as raw materials: The phosphate industry is a highly competitive industry. Whoever wins the market will win the initiative. Many phosphate products are a product with multiple uses, and new uses can be continuously developed in practice. For example, some products are divided into feed grade, food grade and electronic grade according to the amount of impurities. With the improvement of product grade, the benefits can be greatly improved, and some even doubled. Phosphate products belong to the category of fine chemicals, and their production technology is highly confidential.
