What does ethylene taste like? Does ethylene have a taste

Burn it with fire, the smell of paraffin wax is not bad when the polyethylene burns, but the smell of polyvinyl chloride or something is terrible.

Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the minimum use temperature can reach -70 -100), good chemical stability, can resist the erosion of most acids and alkalis (not resistant to acids with oxidizing properties), insoluble in general solvents at room temperature, small water absorption, excellent electrical insulation performance; However, polyethylene is very sensitive to environmental stresses (chemical and mechanical interactions) and has poor resistance to heat aging.

The properties of polyethylene vary from variety to variety and mainly depend on the molecular structure and density.

Types of polyethylene.

1) LDPE: low-density polyethylene, high-pressure polyethylene.

2) LLDPE: Linear Low Density Polyethylene.

3) MDPE: medium density polyethylene, bimodal resin.

4) HDPE: high-density polyethylene, low-pressure polyethylene.

5) UHMWPE: ultra-high molecular weight polyethylene.

6) Modified polyethylene: CPE, cross-linked polyethylene (PEX).

7) Ethylene copolymer: ethylene-propylene copolymer (plastic), EVA, ethylene-butylene copolymer, ethylene-other olefins (such as octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH).

Linear polyethylene with a molecular weight of 3,000,000-6,000,000 is called ultra-high molecular weight polyethylene (UHMWPE). Ultra-high molecular weight polyethylene has a very high strength and can be used to make body armor.

The main methods: liquid phase method (also divided into solution method and slurry method) and gas phase method (phase type of material in the reactor). In China, the slurry method of Ziegler catalyst is mainly used.

Conditions and process description: Ethylene with a purity of more than 99% is polymerized in gasoline at a pressure and temperature of 65-75 in the presence of titanium tetrachloride and monochlorodiethyl aluminum in the presence of catalysts to obtain HDPE slurry. The residual catalyst is destroyed by alcoholization, neutralization, water washing, and ** gasoline and unpolymerized ethylene, and the product is obtained by drying and granulation.

I searched around, but I didn't find it, it seems that there are many kinds of ethylene, and I admit that I am not good at chemistry. -

Ethylene with different molecular structures seems to have different tastes in different environments.

Ask your teacher, and you might be able to stump him.

Ethylene is tasteless.

Slightly sweet, apples, bananas and pineapples are nearing ripe and can accumulate a lot of ethylene gas in an enclosed space. Ethylene is very similar to ethyl acetate diluted at low concentrations.

Summary. Apple ethylene is a colorless and odorless gas, so it does not have a noticeable odor.

Apple ethylene is a colorless and odorless gas, so it does not have a noticeable odor.

Can you tell us more about that?

Apple ethylene, also known as 2-vinyl-1, 3-benzene glycol, is an organic synthetic compound. It is a colorless and transparent liquid with a fragrance similar to apples, hence its name. Apple ethylene is highly volatile, and the taste will vary depending on the ambient temperature and pressure.

At room temperature, the taste of apple ethylene is not strong, but if it is added to the hot state, the jujube may be dismantled and produce some unhealthy odors, so it is necessary to pay attention to safety when using it. In conclusion, apple ethylene is a commonly used industrial raw material, and its volatile properties are the same as those of fruits, and it is often used in perfumes, cosmetics and food.

ethylene has a slight odor", which is the physical property of the gas, which produces the sensation produced by the gas acting on the human sense of smell. What smells ,-- this, you can actually smell it. In fact, it is a fruit scent, and ethylene is a ripening agent.

Generally, it cannot be smelled, and people who are sensitive to odors can smell a little sweetness.
