Difference 1: The number of double bonds is different.

Butadiene has 2 double bonds. The common configuration is 1,3-butadiene, and the structure is as follows:

2-Butene has only 1 double bond. The structure of trans-2-butene is as follows:

Difference 2: The number of cis-trans isomers is different.

Butadiene has no cripphalo trans isomers.

2-Butene has two cistro-trans ignition-slip isomers.

Difference 3: The molecular formula is different.

Butadiene has the molecular formula C4H6. It is a raw material for the manufacture of synthetic rubber, synthetic resin, nylon, etc. On October 27, 2017, the World Health Organization's International Section Silver Cancer Research Agency published a preliminary list of carcinogens, and 1,3-butadiene was in the list of a class of carcinogens.

2-Butene molecular formula C4H8. It is used to make butadiene, gasoline and other chemicals. Inhalation of highly toxic substances.

At very high concentrations, it can replace standard air and cause suffocation due to lack of oxygen. Exposure to decomposition products can lead to health hazards. After exposure, severe effects are delayed.

Butadiene is a very important raw material for synthetic rubber, which has a wide range of uses in the chemical industry. Specifically, in industrial production, the main butadiene preparation method is done by ethylene reaction.

The reaction of ethylene produced by Gongchen Fengzi Industry can be separated from petroleum products, or it can be prepared from ethylene syngas. For the production of butadiene, the most common method is to convert ethylene and propylene to butadiene by alkylation. This reaction usually involves the addition of an alkylating agent to the mixture and needs to be carried out at high temperatures and pressures.

At the same time, this process also needs to be assisted by various catalysts.

In terms of industrial equipment, this process can be carried out in different chemical plants, including oil refineries for oil fields, butadiene production units, etc. These chemical plants need to have a certain scale of production to produce butadiene on a large scale and ensure the quality of the product. In this process, strict control of temperature, pressure, reactant concentration, catalyst, etc., is required to achieve high efficiency, high yield, and high quality production.
