Read： 1182 Time：13months ago Source：Transform the World with Simplicity

Neopentyl glycol (NPG) is an important chemical raw material with a wide range of properties and applications. This article will introduce the properties, production methods, quality standards, safety and market prospects of neopentyl glycol in detail.

1. the properties of neopentyl glycol

neopentyl glycol is a colorless, transparent, faint odor liquid, with high chemical stability and thermal stability, can be miscible with water, alcohol, ether and other solvents. Its molecular structure contains five carbon atoms and two hydroxyl groups, so it has high reactivity and can be used as an intermediate or raw material for many chemical reactions.

2. neopentyl glycol production method

neopentyl glycol production method mainly has two kinds: one is through the reaction of cyclopentadiene and acetaldehyde under acidic conditions, and then through hydrolysis, hydrogenation and other steps; another is by isoprene and hydrogen peroxide epoxidation under acidic conditions, and then through hydrolysis, reduction and other steps. The two methods have their own advantages and disadvantages, and the suitable production process can be selected according to the actual situation.

3. the quality standard of neopentyl glycol

the quality standard of neopentyl glycol mainly includes purity, moisture, acidity, color and other indicators. Among them, the purity is an important indicator to measure the quality of neopentyl glycol, and the purity is generally required to be above 99%. Water, acidity, color and other indicators will also affect the performance and storage stability of neopentyl glycol, so it also needs to be strictly controlled.

4. the use of neopentyl glycol

neopentyl glycol has a wide range of uses, mainly for the production of unsaturated polyester resins, coatings, plasticizers and other chemical products. In unsaturated polyester resins, neopentyl glycol can be used as a crosslinking agent to improve the hardness and chemical resistance of the resin; in coatings, neopentyl glycol can be used as a film-forming agent to improve the weather resistance and water resistance of the coating; In plasticizers, neopentyl glycol can be used as raw materials to produce plasticizer products with excellent properties.

5. the market prospect of neopentyl glycol

With the continuous development of science and technology, the application field of neopentyl glycol is also expanding. In the future, with the improvement of environmental awareness and the improvement of chemical performance requirements, the market demand for neopentyl glycol will further increase. At the same time, with the improvement of production process and technological progress, the production cost of neopentyl glycol will be gradually reduced, further improving its market competitiveness. Therefore, the market prospect of neopentyl glycol is very broad.

6. Storage and transportation
of neopentyl glycol
neopentyl glycol should be stored in a dry, cool, well-ventilated place, away from direct sunlight and high temperatures. During transportation, attention should be paid to prevent leakage and collision, and avoid contact with oxidants, acids, etc.

In conclusion, neopentyl glycol, as an important raw material for the production of chemicals, has a wide range of properties and uses. In the future development, its market demand will further increase, and we also need to strictly control quality standards in the production process to ensure product quality and performance.
