Anhydrous Ethanol (Ethanol absolute) refers to a higher purity of ethanol aqueous solution. Under normal circumstances, the concentration of 99.5% ethanol solution is generally called anhydrous ethanol, anhydrous ethanol is a mixture of ethanol and water. Function and use Ethanol is an important organic solvent, widely used in medicine, coatings, sanitary products, cosmetics, oils and other aspects, accounting for about 50% of the total consumption of ethanol. Ethanol is an important basic chemical raw material, used in the manufacture of acetaldehyde, ethylene, ethylamine, ethyl acetate, acetic acid, chloroethane, etc., and derived from medicine, dyes, coatings, spices, synthetic rubber, detergents, pesticides and other products of many intermediates, its products as many as 300 kinds, the use of ethanol as an intermediate of chemical products is gradually declining. Many products, such as acetaldehyde and acetic acid, no longer use ethanol as raw materials but other raw materials. 75% ethanol aqueous solution has a strong capacity and is commonly used as a disinfectant. Specially refined ethanol can also be used to make beverages. Like methanol, ethanol can be used as an energy source. Some countries have begun to use ethanol ...

Sulfur dioxide (chemical formula: SO2), also known as sulfite anhydride, is the most common sulfur oxide, the main component of sulfuric acid feedstock gas. Sulfur dioxide is a colorless gas with a strong pungent odor and is one of the main pollutants in the atmosphere. The gas is emitted during volcanic eruptions, and sulfur dioxide is also produced in many industrial processes. Because coal and petroleum often contain sulfur compounds, sulfur dioxide is produced when burned. When sulfur dioxide dissolves in water, it forms sulfite (the main component of acid rain). ...

High quality phenol, direct supply by the manufacturer, stable supply, sufficient supply of the company's warehouse, good product effect, quality assurance, fast delivery, according to the time order to determine the logistics, lightning delivery to your designated place. Phenol (Phenol, C6H5OH) [1] is a colorless needle-like crystal with a distinctive odor. [2] It is toxic and is an important raw material in the production of certain resins, fungicides, preservatives, and medicines (such as aspirin). It can also be used to disinfect surgical instruments and dispose of excrement, [3] skin sterilization, itch relief and otitis media. Melting point 43℃, slightly soluble in water at room temperature, easily soluble in organic solvents; When the temperature is higher than 65 ° C, it can be miscible with water in any proportion. Phenol is corrosive and denatures local proteins upon contact. Its solution can be washed with alcohol when it touches the skin. Small amounts of phenol exposed to air are oxidized to quinone by oxygen and appear pink. This method is usually used to test phenol when ferric ions turn purple. ...
