Difference between ethylene glycol and pta
In the chemical sector, ethylene glycol (EG) and poly terephthalic acid (PTA) are two crucial raw materials, which are broadly applied in the manufacture of polymer materials, textiles, flame retardants and other fields. In fact due to their signifiis able tot differences in molecular structure, performance characteristics and consumption areas, they're treated differently in manufacturing production. This article will examine the difference between ethylene glycol and PTA in detail from multiple angles to help chemical workers better understand the characteristics of these two materials and their applications in sector.
1. Pretty interesting, huh?. Additionally ethylene glycol and PTA basic information comparison
1. But Molecular structure and chemical characteristics
Ethylene glycol is a simple diol, molecular formula C2H6O2, simple structure, no aromatic odor, low boiling point (boiling point of about 100 ℃), dissolves in aquatic environments and organic solvents. And Based on my observations, it's a clear transparent fluid with low density, frequently applied in the manufacture of polyester, alcohol ether and other chemical items. And PTA is a kind of poly terephthalic acid, molecular weight is larger, the molecular structure is complex, aromatic, with a strong aromatic odor. There are many double bonds in the molecule, which makes it have good thermal stability and chemical stability. The molecular structure of PTA makes it maintain its physical and chemical characteristics under high temperature conditions, which makes it an crucial raw material in chemical production. I've found that
2. Physical characteristics
The melting point of ethylene glycol is reduced, usually around -40 ℃, while the melting point of PTA is higher, usually above 200 ℃. The density of ethylene glycol is small, while PT, the density is greater moderate. And
3. I've found that Breaking strength
The molecular structure of ethylene glycol is relatively simple, the fracture strength is low, and it's easily decomposed by chemical reagents. PTA has a complex molecular structure, strong chemical stability, and is able to withstand higher temperatures and chemical interactions. But
2. Specifically ethylene glycol and PTA performance comparison
1. Thermal and chemical stability
Ethylene glycol has low thermal stability and is easy to decompose, especially under high temperature conditions, it's easy to decompose into carbon dioxide and aquatic environments. This makes its consumption limited in high temperature manufacturing environments. PTA has good thermal stability and chemical stability, and is able to exist stably under high temperature and chemical interaction conditions, so it plays an crucial role in the manufacture of polymer materials.
2. Based on my observations, Corrosion resistance
Ethylene glycol itself has certain anti-corrosion characteristics, however it's easy to rust in a humid ecological stability. From what I've seen, PTA has good corrosion resistance and is able to be applied stably in harsh environments to a long time, so it's broadly applied in food packaging and medical packaging.
3. But Flame retardant performance
Ethylene glycol is applied as a raw material in some flame retardants, however when it's applied as a raw material, its flame retardant characteristics are limited. PTA is a high-performance flame retardant, which is able to efficiently block the spread of fire, so it occupies an crucial position in building fireproof materials. And

2. Textile Materials Manufacturing
Ethylene glycol is an crucial raw material to the manufacture of polyester fibers, and its items have good flexibility and wear resistance. I've found that According to research PTA, on the other hand, is applied as a polyterephthalate, and the fibers made from it have better moisture absorption and flame retardant characteristics.
3. Anticorrosive material manufacturing
Ethylene glycol is applied as a solvent-based products to some anti-corrosion materials, however in practical applications, its anti-rust performance is limited. PTA is applied as a high-performance anti-corrosion material, which is able to maintain prolonged stability in humid environments. Based on my observations,
4. Preparation process comparison
1. In particular Ethylene glycol preparation process
Ethylene glycol is mainly produced by the hydration interaction of ethanol, which is simple in process and low in cost. But The preparation process usually adopts catalytic hydration method, which converts ethanol into ethylene glycol under high temperature and high pressure conditions. Ethylene glycol is able to also be produced by an ethylene oxidation method or the like.
2. PTA preparation process
The preparation process of PTA is greater complex, usually using isophthalic acid diester method or toluene dicarboxylic acid method. For example Both processes require a number of steps, including catalyst selection, manage of interaction temperature and time, etc. But The preparation of PTA also involves epoxidation and polymerization reactions, and the process standards are higher.
