The question of the reaction of ethylene and benzene high score bounty is answered by the master

The catalytic dry gas after the removal of propylene enters the alkylation reactor. The circulating benzene from the separated part is divided into two ways, one of which is gasified by the reaction product-circulating benzene heat exchanger, and then heated to the required temperature by the circulating benzene heating furnace, and then enters the top of the hydrocarbonation reactor to react with ethylene and other olefins in the dry gas. After the hydrocarbonation reaction product is heated with the feed of circulating benzene and circulating benzene tower, it is condensed and cooled by circulating water and chilled water, and the gas liquid after condensation and cooling enters the bottom of the absorption tower of the separation part.

The anti-hydrocarbonation material from the separation part and the other circulating benzene from the separated part enter the anti-hydrocarbonation reactor after heat exchange through the heat exchanger and the reaction temperature, and the anti-hydrocarbonization reaction product enters the circulating benzene tower after heat exchange.

The alkylated tail gas from the reaction part enters the bottom of the absorption tower, and is in reverse contact with the top-down absorbent, absorbing most of the benzene and recombinant components in the alkyl tail gas, and the tail gas is sent out of the device from the top of the tower. The absorbent and the absorbed benzene are reconstituted together, and the bottom of the self-absorption tower is pumped to the feeding tank of the circulating benzene tower.

Benzene and non-condensable gas are evaporated from the top of the tower into the steam generator at the top of the circulating benzene tower, and after condensation and cooling, they enter the reflux tank of the circulating benzene tower for flashing, and the condensate after flash is pumped into the top of the tower as a reflux pump, and the gas after flash is cooled by circulating water and sent directly out of the device. The material at the bottom of the column is pressurized by the pump and sent to the ethylbenzene distillation tower as the feed of the tower. The circulating benzene is extracted from the side line of the circulating benzene tower and pumped to the reaction section.

After the feed of the ethylbenzene distillation tower enters the ethylbenzene distillation tower, the ethylbenzene is evaporated from the top of the column, enters the steam generator at the top of the ethylbenzene distillation tower for condensation, and the condensate enters the reflux tank of the ethylbenzene distillation tower. The condensate is pressurized by the reflux pump of the ethylbenzene distillation tower and divided into two routes, one is driven to the top of the column as a return, and the other is cooled by the ethylbenzene cooler until it is sent to the ethylbenzene product tank, and then pumped out of the device. The bottom material is sent downstream for further separation of propylene and polyethylbenzene, of which polyethylbenzene is sent to the reaction section as a dehydrocarbonization feedstock.

Therefore, the product produced by the anti-hydrocarbonation reactor is ethylbenzene.

1. At present, there are three major styrene technology companies in China, Badger, Lummus and Sinopec, ethylene and benzene enter the alkylation reactor, and the main ones that come out are benzene, ethylbenzene and polyethylbenzene, and the materials from the alkylation reactor enter the benzene tower, and the benzene at the top of the tower returns to the alkylation and alkyl transfer reactor, and the ethylbenzene and polyethylbenzene of the tower kettle enter the ethylbenzene tower, and the ethylbenzene enters the ethylbenzene tower from the top of the ethylbenzene tower, and the polyethylbenzene at the bottom of the ethylbenzene tower enters the polyethylbenzene tower. The polyethylbenzene evaporated from the top of the polyethylbenzene tower enters the alkyl transfer reactor, reacts with benzene, produces ethylbenzene, and returns to the benzene tower!

2. The anti-alkylation reactor (alkyl transfer reactor) is added with polyethylbenzene and benzene, and the main thing that comes out is ethylbenzene, as well as a small amount of benzene and polyethylbenzene!

If you still have questions, please add!

The main hydrocarbonization reactor is generated.

Circulation towers are what increase conversions.

Dear, if you see my reply, please reply 1, thank you for your support.

Pro, benzene and ethylene undergo an addition reaction to form ethylbenzene.

It can react to form ethylbenzene.

Benzene and ethylene are alkylated to form ethylbenzene, and a molecule of ethylene reacts with a molecule of benzene under appropriate conditions to form a molecule of ethylbenzene. About 90% of ethylbenzene in industry is now produced by benzene alkylation.

Under the action of the catalyst, ethylbenzene is dehydrogenated to form styrene when it reaches 550 600.

It does not react, styrene is not prepared from benzene and ethylene, and in industry, styrene can be produced by catalytic dehydrogenation of ethylbenzene. In the laboratory, cinnamic acid can be obtained by heating it.

Benzene and ethylene are produced by a catalyst to produce phenylethythane, which is then replaced by chlorine under light conditions and then eliminated.

When it comes to organic naming, benzene rings.

The status is very low, and it can only be used as a substituent. So this substance:

The normal nomenclature is "styrene", not "vinylbenzene".

I guess you might be saying "(right) divinylbenzene":

When there are two vinyl groups attached to the benzene ring.

, it is inconvenient to use ethylene as the parent name, so benzene is used as the parent and named "divinylbenzene". Look

Styrene is also known as vinylbenzene.

Under the action of laser, it is a free radical reaction, first of all, there is a homolysis between the benzene ring and the hydrogen to produce hydrogen radicals and benzene radicals, and the hydrogen radicals react with ethylene to become ethyl radicals, and then combine with benzene radicals to form ethylbenzene.

c6h6+ch2=ch2—c6h5ch2ch3

The reaction conditions are under the conditions of the laser.

The word definition of styrene is: styrene běnyǐxī. (1) Organic compounds with the molecular formula C6H5CH=CH2, usually colorless and aromatic liquids. It is used to make plastics, synthetic rubber, etc.

The word definition of styrene is: styrene běnyǐxī. (1) Organic compounds with the molecular formula C6H5CH=CH2, usually colorless and aromatic liquids.

It is used to make plastics, synthetic rubber, etc. The phonetic pronunciation is: one by one.

The structure is: benzene (upper and lower structure) ethylene (monomeric structure) and ene (left and right structure). The pinyin is:

What is the specific explanation of styrene, we will introduce it to you through the following aspects:

1. Chinese dictionary [click here to view the details of the plan].

An organic compound. It is aromatic, colorless and transparent liquid, flammable and slightly toxic. It is used in the production of plastics, resins and rubber.

Translations of words in English, styrene, German, styrol, styren, vinylbenzol, phenylethylen (eig, chem), French, styrène

2. Network Explanation.

Styrene styrene (C8H8) is an organic compound formed by replacing a hydrogen atom of ethylene with benzene, the electrons of vinyl are conjugated with benzene ring, insoluble in water, soluble in ethanol and ether, and gradually polymerized and oxidized when exposed to air. Industrially, it is an important monomer of synthetic resins, ion exchange resins and synthetic rubber. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) released a preliminary list of carcinogens, and styrene was included in the list of class 2b carcinogens.

Summary. Hello, in secondary school is not responsive. The two can coexist.

Styrene is an important organic chemical raw material. The pyrolysis gasoline of the steam cracking ethylene plant, which is made from naphtha, diesel, liquefied natural gas, etc., contains about 4-6% styrene. Styrene from pyrolysis gasoline involves the separation of styrene from other C 8 aromatic hydrocarbons, in which o-xylene and styrene only differ in boiling points, and it is difficult for ordinary distillation to effectively separate the two.

Xylene and styrene can be synthesized can xylene react with styrene.

Hello, this is Universal Cabin! I'm very honored to ask you this question, I need a little time to answer, please be patient for about five minutes!

Do xylene and styrene react.
