Pentaerythritol (Pentaerythritol, PE) is an important raw material for chemical production, which is widely used in various fields. This article will detail the properties and uses of pentaerythritol.
1. pentaerythritol properties
1. Physical properties
pentaerythritol is a white crystalline powder, sweet, non-toxic, non-corrosive. It has a high melting point (261-262 ℃) and boiling point (276 ℃), insoluble in water, but soluble in alcohol, ether, acetone and other organic solvents.
2. chemical properties
pentaerythritol contains four hydroxyl groups, with strong reducibility and alcohol hydroxyl reactivity, can react with acids, esters, ethers, aldehydes, ketones, etc., to generate the corresponding derivatives. In addition, pentaerythritol also has good thermal stability and can be used at high temperatures.
2. pentaerythritol use
1. plastic additives
pentaerythritol can be used as plastic additives, used to improve the toughness of plastic, strength, hardness and other properties. It can be made into pentaerythritol formaldehyde resin by reacting with formaldehyde, which has good water resistance, heat resistance, weather resistance and other properties. It can be used in the manufacture of plastic products, such as water pipes, doors and windows.
2. Coating additive
pentaerythritol can be used as a coating additive to improve the drying, adhesion, weather resistance and other properties of the coating. It can be made into pentaerythritol fatty acid ester by reacting with fatty acid, which has good emulsification, wettability, dispersion and other properties, and can be used in the manufacture of latex paint, ink and other coatings.
3. explosive raw material
pentaerythritol can be used as explosive raw material for the manufacture of explosives. It reacts with nitric acid to make pentaerythritol tetranitrate, which is a high explosive and can be used in military, mining and other fields.
4. pharmaceutical intermediates
pentaerythritol can be used as pharmaceutical intermediates for the manufacture of drugs. It can react with aldehydes, ketones, etc. to make corresponding protective agents, reducing agents, etc., and can be used to synthesize antibacterial drugs, antitumor drugs and other drugs.
In conclusion, pentaerythritol, as an important raw material for chemical production, has a wide range of applications and good market prospects. In the future development, with the continuous progress of science and technology and the continuous expansion of application, the use of pentaerythritol will be more extensive, bringing more contributions to the development of various fields.
