Ethylene glycol is a tintless, odorless, sweet liquid with a low toxin to creatures. Ethylene glycol is miscible with water and acetone but has low solubility in ethers. So what are the uses and preventives of ethylene glycol? Let's take a look next.

Use

Ethylene glycol is substantially used to make polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics, and snares, and also used as a detergent for colorings, inks, etc., antifreeze for formulating machines, gas dehydrating agent, resin, water-soaking agent for cellophane, fiber, leather, glue. It can produce synthetic resin PET, fiber grade PET is polyester fiber, and bottle flake grade PET is used to make mineral water bottles, etc. It can also produce alkyd resin, glyoxal, etc., and is also used as antifreeze. In addition to being used as an antifreeze for motorcars, it's also used for the transportation of artificial refrigeration, generally called a refrigerant, and can also be used as a condensing agent like water.

Ethylene glycol methyl ether series products are high-grade organic detergents with excellent performance. They're used as detergents and diluents for publishing inks, artificial cleaning agents, coatings (nitrocellulose makeup, shield, enamel), bobby- sheathe laminates, printing, and dyeing, etc.; they can be used for the product of fungicides interceders, pharmaceutical interceders, and raw accouterments for chemical products similar as synthetic boscage fluids; as electrolytes for electrolytic capacitors, leather- making chemical fiber colorings, etc. Used as cloth auxiliaries, synthetic liquid colorings, and raw accouterments for desulfurization in toxin and canvas refining products.



Preventives when making refrigerant

1. Its freezing point changes with the attention of ethylene glycol in the waterless result. When the attention is below 60, the attention of ethylene glycol in the waterless result increases and the freezing point decreases, but when the attention exceeds 60, with the increase of ethylene glycol attention, its freezing point is on the rise, and the density will also increase with the increase of the attention. When the attention reaches99.9, its freezing point rises to-13.2 °C, which is an important reason why the concentrated antifreeze (antifreeze mama result) can not be used directly, and the stoner must pay attention.

2. Ethylene glycol contains hydroxyl groups. When working at 80 ℃-90 ℃ for a long time, ethylene glycol will be oxidized to glycolic acid first, and also oxidized to oxalic acid, videlicet oxalic acid (oxalic acid), which contains 2 carboxyl groups. Oxalic acid and its by-products affect the central nervous system first, also the heart, and also the feathers. Ethylene glycol oxalic acid can beget erosion to outfit and beget leakage. Thus, in the set antifreeze, there must also be preservatives to help erosion of sword and aluminum and the conformation of scale.


The over is about the use and preventives of ethylene glycol. However, please communicate with us, if you're interested in ethylene glycol. Our website iswww.hiseachem.com. I look forward to your appearance veritably much and hope to cooperate with you.
