Einecs 231-181-6 - Introduction
pentaerythritol octahydrogen tetraphosphate (abbreviated as Pentaerythritol Tetraphosphate) is an organic phosphate ester compound. Its nature is as follows:
1. Appearance: pentaerythritol octahydrogen tetraphosphate is usually a white crystalline solid or powder.
2. Melting point and boiling point: its melting point is about 158-162 ℃, no obvious boiling point.
3. Solubility: It is insoluble in water, but soluble in organic solvents such as alcohols and ketones.
The pentaerythritol octahydrogen tetraphosphate has the following uses:
1. Flame retardant: Due to its good flame retardant properties, pentaerythritol octahydrogen tetraphosphate is often used as an additive for flame retardant materials such as plastics, coatings, and adhesives.
2. Preservative: It can also be used as a preservative in water-based coatings and adhesives to effectively extend its service life.
3. Antioxidant: pentaerythritol octahydrogen tetraphosphate can be used as an antioxidant in synthetic rubber to prevent aging and deterioration caused by oxygen.
The preparation method of pentaerythritol octahydrogen tetraphosphate is generally obtained by reacting pentaerythritol with dehydrated phosphoric anhydride. Specific synthesis methods include transesterification, chlorophosphate esterification, and the like.
When using pentaerythritol octahydrogen tetraphosphate, you need to pay attention to the following safety information:
1. Use should wear personal protective equipment, such as safety glasses, protective gloves and protective clothing.
2. Avoid contact with skin, eyes and respiratory tract, such as accidental contact, should immediately rinse with water.
3. In the use and storage process, need to stay away from fire and high temperature, direct sunlight and other flammable and heat sources.
4. Store in a cool and dry place, away from acids and oxidants.
It should be noted that the information provided above is for reference only. Please read the product safety data sheet carefully before use and follow the relevant operating procedures.
