Main purpose

industry

1. ethylene is an important basic raw material of organic chemical industry, which is mainly used to produce polyethylene, ethylene propylene rubber, polyvinyl chloride, etc;

2. one of the most basic petrochemical raw materials. In terms of synthetic materials, it is widely used in the production of polyethylene, vinyl chloride and polyvinyl chloride, ethylbenzene, styrene and polystyrene, ethylene propylene rubber, etc; In organic synthesis, it is widely used to synthesize ethanol, ethylene oxide, ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid and their derivatives and other basic organic synthesis raw materials; Through halogenation, chloroethylene, chloroethane and bromoethane can be prepared; Can be prepared by oligomerization α- Olefins, and then produce higher alcohols, alkylbenzene, etc;

3. it is mainly used as standard gas for analytical instruments in petrochemical enterprises;

4. ethylene is used as environment-friendly ripening gas for navel orange, tangerine, banana and other fruits;

5. ethylene is used in pharmaceutical synthesis and high-tech material synthesis

ecology

1. triple response of ethylene: ① inhibiting the elongation and growth of stems; ② Promote the thickening of stems and roots; ③ Promote the lateral growth of stem. The stems of etiolated seedlings treated with ethylene could make the stems thicker and the petioles grow upward.

2. ethylene can promote the synthesis of RNA and protein, increase the permeability of cell membrane in higher plants and accelerate respiration. Therefore, when the ethylene content in fruits increases, the synthesized auxin can be decomposed by enzymes in plants or external light, further promoting the transformation of organic substances and accelerating maturation. Soaking immature tomato, apple, pear, banana, persimmon and other fruits in common ethephon solution can significantly promote ripening.

3. ethylene can also promote organ abscission and aging. Ethylene plays an important role in flower, leaf and fruit abscission.

4. 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, lacquer trees, etc.

5. ethylene can also induce the formation of adventitious roots of cuttings, promote the growth and differentiation of roots, break the dormancy of seeds and buds, and induce the secretion of secondary substances.
