Anonymous users2024-02-10The difference between polyester grade ethylene glycol and chemical fiber grade ethylene glycol is that they differ in structure and chemical properties.
Ethylene glycol is also known as glycol, abbreviated as EG. The chemical formula is (CH2OH)2 and is the simplest diol. Ethylene glycol is a colorless, odorless, sweet-smelling liquid that is toxic to animals and has a lethal dose of about g kg for humans. Ethylene glycol can be combined with water and acetone.
Intermiscible, but less soluble in ethers. It is used as a solvent, antifreeze and raw material for synthetic polyester. Polyethylene glycol, a polymer of ethylene glycol.
PEG) is a phase transfer catalyst that is also used in cell fusion; Its nitrate is an explosive. with water ethanol.
Acetone acetic acid.
Glycerol pyridine is miscible, slightly soluble in ether, insoluble in petroleum hydrocarbons and oils, and can dissolve calcium chloride, zinc chloride, sodium chloride, potassium carbonate, potassium chloride, potassium iodide, potassium hydroxide and other inorganic substances. Nitrite, a derivative of ethylene glycol, is an explosive. Monomethyl ether or monoether of ethylene glycol is a good solvent such as the methyl fibrinolytic agent hoch2ch2och3 to dissolve fibers, resins, paints, and many other organic substances.
Ethylene glycol has a strong solubility ability, but it is easy to metabolize and oxidize to produce toxic oxalic acid, so it cannot be widely used as a solvent.

Anonymous users2024-02-08Hello dear! We'll be happy to answer for you. Is polyester grade ethylene glycol the same as polyester grade ethylene glycol?
Hello dear, the ethylene glycol purity of polyester grade ethylene glycol is colorless, odorless, sweet, no impurities, and relatively high. Polyester grade ethylene glycol** is cheap, has many impurities, is light yellow in color, and has a peculiar smell; Ethylene glycol, also known as glycol. Chemical formula Hoch2—CH2OH.
A simple diol. Colorless, odorless, and disturbing sweet liquid grip body, it can be mixed with water in the proportion of Ren Duan Li Biyi. It is used as a raw material for solvents, antifreeze, and synthetic polyester resins.

Anonymous users2024-02-07Polyester-grade glycol and polyester-grade glycol are not identical, although they are both derivatives of ethylene glycol.
Polyester-grade ethylene glycol is a polymer prepared by esterifying ethylene glycol with diacid. It has a high molecular weight and viscosity and is often used in the preparation of polyester resins, coatings, paints, plastics, etc.
Polyester grade ethylene glycol is a purpose-specific ethylene glycol that is used in the preparation of polyester in polyester fibers. It has a high purity and a specific molecular weight range to ensure the performance and quality of the final polyester fiber.
Although both polyester-grade and polyester-grade glycol are prepared from ethylene glycol, their uses and preparation processes are slightly different. Therefore, it is important to choose the right glycol grade for your specific application and needs.

Polyester grade ethylene glycol is: ethylene glycol with a concentration of colorless, odorless, sweet liquid, without any impurities, and ** is relatively high.
The two are the same thing, which is what we usually call ethylene glycol. >>>More

The proportion of ethylene glycol is 40 to 50 percent. When the glycol content is 68, the freezing point can be reduced to -68, and when this limit is exceeded, the freezing point will rise. 40 ethylene glycol and 60 soft water mixed into antifreeze, antifreeze temperature of -25; When ethylene glycol and water account for 50 each in the antifreeze, the antifreeze temperature is -35. >>>More
