Pangunahing gamit
industry
1. Ethylene is an important basic organic chemical raw material, mainly used in the production of polyethylene, ethylene propylene rubber, polyvinyl chloride, etc;
2. One of the most basic raw materials in petrochemical industry. In terms of synthetic materials, it is widely used in the production of polyethylene, vinyl chloride, polyvinyl chloride, ethylbenzene, styrene, polystyrene, and ethylene propylene rubber; In terms of organic synthesis, it is widely used to synthesize various basic organic synthesis raw materials such as ethanol, ethylene oxide, ethylene glycol, acetaldehyde, acetic acid, propionic acid, and their derivatives; Through halogenation, chloroethylene, chloroethane, and bromoethane can be produced; By gathering together, it can be made α- Alkenes are used to produce higher alcohols, alkylbenzenes, etc;
3. Mainly used as standard gas for analytical instruments in petrochemical enterprises;
4. Ethylene is used as an environmentally friendly ripening gas for fruits such as navel oranges, honey oranges, bananas, etc;
5. Ethylene used in pharmaceutical synthesis and high-tech material synthesis
ecology
1. Triple response of ethylene: ① Inhibiting stem elongation and growth; ② Promote the thickening of stems and roots; ③ Promote lateral growth of stems. Treating yellowed seedling stems with ethylene can make the stems thicker and the petioles grow upwards.
2. As ethylene can promote the synthesis of RNA and proteins, and increase the permeability of cell membranes in higher plants, it accelerates respiration. Therefore, when the ethylene content in fruits increases, the synthesized auxin can be decomposed by enzymes in the plant or external light, further promoting the transformation of organic matter and accelerating maturity. Soaking partially ripe fruits such as tomatoes, apples, pears, bananas, and persimmons in commonly used ethylene solution can significantly promote ripening.
3. Ethylene also has the effect of promoting organ shedding and aging. Ethylene plays an important role in the shedding of flowers, leaves, and fruits.
4. Ethylene can also promote the flowering and female flower differentiation of certain plants (such as melons), and promote the discharge of milk from rubber trees, lacquer trees, and others.
5. Ethylene can also induce the formation of adventitious roots in cuttings, promote root growth and differentiation, break seed and shoot dormancy, and induce the secretion of secondary substances.

Precautions for ethylene gas: Closed operation, comprehensive ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear anti-static work clothes. Stay away from sparks and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent gas leakage into the workplace air. Avoid contact with oxidants. During the transportation process, steel cylinders and containers must be grounded and bridged to prevent the generation of static electricity. Light loading and unloading during transportation to prevent damage to steel cylinders and accessories. Equip corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Store in a cool and ventilated warehouse. Stay away from sparks and heat sources. The storage temperature should not exceed 30 ℃. It should be stored separately from oxidants and avoid mixing. Adopting explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks.
Ethylene gas is a compound composed of two carbon atoms and four hydrogen atoms.Two carbon atoms are connected by double bonds. Ethylene is the basic chemical raw material for synthetic fibers, synthetic rubber, synthetic plastics (polyethylene and polyvinyl chloride), and synthetic ethanol (alcohol). It is also used in the production of vinyl chloride, styrene, ethylene oxide, acetic acid, acetaldehyde, ethanol, explosives, and can be used as a ripening agent for fruits and vegetables. It is a proven plant hormone.
