2. It used as a solvent for dyes, inks, etc
3..Mainly used for making polyester fiber, polyester resin, dehumidifying agents, plasticizers, surfactants, synthetic fibers.
Packaging storage and transportation
1. Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. It should be stored separately from oxidants and acids, and avoid mixing storage. Equip with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials. Due to its strong hygroscopicity, it should be stored in a sealed manner, and long-term storage should be sealed with nitrogen gas. Can be stored in containers made of iron, soft steel, copper, or aluminum. However, coated steel, aluminum, or stainless steel containers are suitable for long-term storage.
2. The ethylene glycol container should be labeled with the word "toxic" to prevent accidental ingestion and inhalation of ethylene glycol vapor. Operators should wear protective equipment and undergo regular physical examinations, especially urine routine tests.

Application purpose
Usage:
1. Mainly used for manufacturing polyester fibers, polyester resins, dehumidifiers, plasticizers, surfactants, synthetic fibers,
2. Can be used as a dye/ink solvent, to prepare engine antifreeze, and for gas dehydration.
3. Used for producing synthetic resin, PET or polyester fiber grade PET, and bottle grade PET film for producing mineral water bottles.
4. It can also produce alkyd resin and be used as an antifreeze agent.
Mainly used in the production of polyester, polyester, polyester resin, moisture absorbent, plasticizer, surfactant, synthetic fiber, cosmetics, and explosives.
And it can be used as a solvent for dyes, inks, etc., as an antifreeze agent for engine formulation, as a gas dehydrating agent, in the manufacture of resins, and as a wetting agent for glass paper, fibers, leather, and adhesives.
It can produce synthetic resin PET, fiber grade PET (polyester fiber), and bottle grade PET for making mineral water bottles, etc. It can also produce alkyd resin, formaldehyde, etc., and is also used as an antifreeze agent.
In addition to being used as an antifreeze for automobiles, it is also used for the transportation of industrial cooling capacity, generally referred to as a refrigerant. At the same time, it can also be used as a condensing agent like water.
When using ethylene glycol as a refrigerant, attention should be paid to:
1. Its freezing point changes with the concentration of ethylene glycol in aqueous solution. When the concentration is below 60%, the concentration of ethylene glycol in the aqueous solution increases and the freezing point decreases. However, when the concentration exceeds 60%, the freezing point shows an upward trend with the increase of ethylene glycol concentration, and the viscosity also increases with the increase of concentration. When the concentration reaches 99.9%, its freezing point rises to -13.2 ºC, which is an important reason why concentrated antifreeze (antifreeze mother liquor) cannot be used directly and must be noted by users.
2. Ethylene glycol contains hydroxyl groups. When operated at temperatures between 80 ° C and 90 ° C for a long time, ethylene glycol is first oxidized to glycolic acid and then to oxalic acid, which contains two carboxyl groups. Oxalic acid and its by-products first affect the central nervous system, followed by the heart, and then the kidneys. Ethylene glycol oxalic acid causes corrosion and leakage of equipment. Therefore, in the prepared antifreeze, preservatives must also be present to prevent corrosion of steel and aluminum and the formation of scale.
Ethylene glycol methylether series products are high-performance advanced organic solvents used as solvents and diluents for printing inks, industrial cleaning agents, coatings (nitrocellulos paints, varnishes, porcelain paints), copper-clad laminates, printing and dyeing, etc. But it is prone to metabolism and oxidation to produce toxic oxalic acid, so it cannot be widely used as a solvent.
It can be used as an intermediate for the production of pesticides and pharmaceuticals, and is an intermediate for the fungicides tebuconazole and oxytetracycline. And raw materials for synthetic brake fluid and other chemical products; Leather chemical fiber dyes, etc.
Adding ethylene glycol to hydraulic fluid can prevent oil-based hydraulic fluid from corroding the rubber in the system; Water based hydraulic fluid mainly composed of ethylene glycol is a non combustible hydraulic fluid used in molding machines for aircraft, automobiles, and high-temperature operations.
Used as a textile additive, synthetic liquid dye, and raw material for desulfurizer in fertilizer and oil refining production.
Used as analytical reagents, chromatographic analysis reagents, and capacitive media.
