It is easy to absorb moisture at high concentration.
Application
It is mainly used for making polyester, polyester, polyester resin, hygroscopic agent, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, and used as dyes, ink and other solvents, preparation of engine antifreeze, gas dewatering agent, manufacturing resin, can also be used in cellophane, fiber, leather, adhesive wetting agent. Can produce synthetic resin PET, fiber grade PET, namely polyester fiber, bottle sheet grade PET is used for making mineral water bottles, etc. Also can produce alkyd resin, glyoxal, and so on, but also used as antifreeze. In addition to being used as an antifreeze agent for automobiles, it is also used for the transportation of industrial cooling capacity, generally known as the carrier cooling agent, and at the same time, it can also be used as water as a condensate agent.
Ethylene glycol methyl ether series products are advanced organic solvents with excellent performance, used as solvent and thinner for printing ink, industrial cleaning agent, paint (nitrofiber paint, varnish, porcelain paint), copper coating plate, printing and dyeing; can be used as raw materials for chemical products such as pesticide intermediates, pharmaceutical intermediates and synthetic brake fluid; as electrolyte for electrolytic capacitor, leather chemical fiber dye, etc. It is used as textile additives, synthetic liquid dyes, as well as fertilizer and desulfurizer in oil refining production.
Ethylene glycol should be noted when used as a load cooling agent:
1. The freezing point changes with the concentration of ethylene glycol in aqueous solution. When the concentration is below 60%, the concentration of ethylene glycol in aqueous solution increases and the freezing point decreases, but after the concentration exceeds 60%, with the increase of ethylene glycol concentration, the freezing point is rising, and the viscosity will also increase with the increase of the concentration. When the concentration reaches 99.9%, its freezing point rises to-13.2℃, which is an important reason why the concentrated antifreeze liquid (antifreeze mother liquor) cannot be directly used, and must attract the attention of users.
2. Ethylene glycol contains hydroxyl group, working at 80 degrees Celsius-90℃ for a long time, ethylene glycol is first oxidized to glycolic acid, and then oxidized to oxalic acid, that is, acetic acid acid (oxalic acid), contains two carboxyl groups. Oxalic acid and its side products first affect the central nervous system, then the heart, and then the kidneys. Ethylene glycol diacetic acid, causing corrosion to the equipment and leakage. Therefore, in the prepared antifreeze liquid, there must also be preservatives, to prevent the corrosion of steel and aluminum and scale generation.
Packaging storage and transportation
Package in galvanized iron barrels, 100 Kg or 200 Kg per barrel. Storage should be sealed, long-term storage to nitrogen sealing, moisture-proof, fireproof, anti-freezing. Storage and transport according to flammable chemicals
