The Main Application
- Ethylene is an important basic raw material for organic chemicals. It is mainly used for the production of polyethylene, ethylene-propylene rubber, and polyvinyl chloride.
- One of the most basic raw materials of petrochemical industry. In terms of synthetic materials, it is widely used in the production of polyethylene, vinyl chloride and polyvinyl chloride, ethylbenzene, styrene and polystyrene, and ethylene-propylene rubber; in organic synthesis, it is widely used in the synthesis of ethanol, ethylene oxide, and Ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid and its derivatives and other basic organic synthetic raw materials; halogenated to produce vinyl chloride, chloroethane, bromoethane; oligomerized to produce α-olefins to produce higher alcohols, alkylbenzenes, etc .;
- Standard gas mainly used as analytical instrument in petrochemical enterprises;
- Ethylene is used as an environmentally-friendly ripening gas for fruits such as navel orange, tangerine, and banana;
- Ethylene used in pharmaceutical synthesis and high-tech materials synthesis
- Ethylene “triple response of ethylene”:
- inhibit stem elongation and growth;
- promote thickening of stems and roots;
- promote lateral growth of stems. Treatment of yellowing seedling stems with ethylene can make the stems thicker and the petioles higher.
- Since ethylene can promote the synthesis of RNA and proteins, and can increase the permeability of cell membranes in higher plants, and accelerate respiration, so when the ethylene content in fruits increases, the synthesized auxin can be replaced by enzymes in the plant. Or it is decomposed by external light, which further promotes the conversion of organic substances and accelerates maturity. Commonly used ethephon solutions to soak immature tomatoes, apples, pears, bananas, persimmons and other fruits can significantly promote maturity.
- Ethylene also promotes organ shedding and aging. Ethylene plays an important role in the shedding of flowers, leaves and fruits.
- Ethylene can also promote the flowering and female flower differentiation of some plants (such as melons), and promote the excretion of milk from rubber trees and lacquer trees.
- Ethylene can also induce the formation of adventitious roots, promote root growth and differentiation, break the dormancy of seeds and buds, and induce the secretion of secondary biomass.
