What is mixed xylene?
In a simple definition or statement in response to the question of what mixed xylene is, it can be said that it is an aromatic hydrocarbon. Xylene, or in other words, dimethylbenzene, is the name of 3 isomers (para-xylene, ortho-xylene, and finally meta-xylene). Due to the mixture of these three types of isomers, it will be called a mixture of xylene. It is interesting to know that xylene is a clear and colorless liquid and is in the group of aromatic hydrocarbon compounds. Structurally, this colorless substance is composed of two methyl groups and a benzene ring, which are attached to the benzene ring in various positions. This chemical is highly flammable and very toxic. The person who works with it must have received all the necessary training to work with this toxic substance and must also carry safety equipment. It is better to store this chemical in cool and well-ventilated environments. A significant point that you need to know in this regard is that to store this substance, you must Keep away from heat, sources of ignition and sunlight.

History of xylene
It is worth noting that xylene was first discovered and identified in 1850 by a French chemist (Auguste Cahors). Around 2000 to 2014, nearly 577.6 million tons of this special application material were produced. Annually, more than There will be a demand of 60 million tons for xylene production in the world.
Use of mixed xylene
The main use of this toxic chemical (xylene) is to use it as a solvent. It is interesting to know that this substance is one of the 30 main compounds in the industry and has a very high production.
In the following text, we intend to briefly discuss some of the uses of this chemical (mixed xylene):
- This chemical (as a supplement) is added to benzene.
- The isomers of this colorless toxic substance are used in the production of many substances (as solvents).
- The isomers of this substance (as intermediates) are used in photosynthetic reactions.
- This substance is used in the production of various substances such as (dimethyl terephthalate, ethylbenzene and also terephthalic acid) is used.
- It is one of the most widely used consumables in laboratories. It is used to keep reaction tanks cool for making ice.
- It is interesting to know that xylene is used as a raw material in the production of ethylbenzene.
- In the adhesive industry, this widely used material is used to produce adhesives and reduce their viscosity.
- In the dental industry, xylene is used for slip coating, painting and tissue processing.
- Xylene is used to wash tanks of aircraft, tankers and transportation equipment such as railway tracks.
- In industries where high resistance of products to water and its penetration is required, in other words, waterproof industries, xylene is used.
- In the paint industry, this material is used as a polisher and They use paint thinners.

Xylene production
Xylene mixture is known and introduced as the second most important aromatic product used in the chemical industry worldwide. This mixture is before toluene and behind benzene in terms of importance. It is interesting to know that this mixture is produced in several different ways. Generally, this mixture is produced by a process called catalytic reformate.
However, a very large portion of this mixture will be consumed in the refinery (to increase the octane number of benzene). As we mentioned in the text above, xylene mixture is one of the 30 superior substances whose production method is of great interest in the world. This mixture can be prepared naturally by alkylation (in crude oil). It should be noted that it can be prepared industrially through benzene or toluene methylation.
Harms, dangers and side effects of mixed xylene
As we mentioned in the text above, mixed xylene is a flammable gas. This dangerous substance may catch fire at temperatures below 17 degrees Celsius and is ineffective in extinguishing water explosions, etc. because it does not have the ability to cool mixed xylene.
The vapors of mixed xylene (XYLENE) are very toxic and when in contact with the eyes, they may cause problems such as redness, itching, burning nose, sore throat and sometimes cause serious damage. Breathing the vapors of this substance will cause nausea, headache, lethargy and …. Oxygen should be connected to this person as soon as possible.
Eating this chemical will stimulate the person’s central nervous system. Sometimes it will cause poisoning, kidney and nervous disorders, hearing loss or death. It is better to know that this material should not come into contact with clothing and skin. Gloves, protective clothing, masks and goggles should be used when handling mixed xylene.

Synthesis of mixed xylene
Mixed xylene is produced in various ways, but the majority of production is obtained from the reforming process. When oil cuts enter the reforming process in refineries, mainly aromatic products will be the output product. This method is used for 70% of all mixed xylene production in the world.
Other methods of producing dimethylbenzene include carbonization of coal in the process of making coke fuel, the process of converting toluene to xylene, or methylation between xylene and toluene. Mixed xylene isomers can be separated from each other using distillation, crystallization, and absorption processes.
Safety tips for mixed xylene
It is possible that the toxic vapors of this substance may mix with room air at temperatures below 17 degrees Celsius and cause an explosion. Sometimes the vapors of this dangerous substance can ignite due to static electricity. To extinguish the fire, it is best to use carbon dioxide, foam, dry chemical powder, water mist, and appropriate spray.
