###1.2-chloro-1,3-butadiene as raw material
2-chloro-1,3-butadiene (also known as chloroprene) is an important monomer for the synthesis of neoprene rubber. Neoprene can be synthesized by radical polymerization. In the presence of an appropriate initiator (such as peroxide, etc.), the double bonds in the chloroprene molecule open and connect to each other to form a long chain polymer. The reaction process is as follows: the initiator decomposes to produce free radicals, and the free radicals attack the double bonds of the chloroprene monomer, causing it to undergo an addition reaction to form new free radicals. The new free radicals continue to react with other chloroprene monomers, and so on repeatedly, to achieve chain growth, and finally form chloroprene rubber with a certain molecular weight.

###2. Synthesis of 1,3-butadiene as raw material
1,3-butadiene first undergoes a 1,4-addition reaction with chlorine gas to generate 1,4-dichloro-2-butene. The reaction conditions are generally carried out at a lower temperature in a suitable solvent (such as an inert organic solvent) to facilitate the formation of 1,4-addition products. After that, 1,4-dichloro-2-butene undergoes elimination reaction under basic conditions, and hydrogen chloride is removed to obtain 2-chloro-1,3-butadiene. For example, an alcohol solution of sodium hydroxide is used as the reaction system, and the elimination reaction is promoted under heating conditions.

##3. Synthesis of acetylene as raw material
Two-molecule acetylene In the catalytic system of cuprous chloride-ammonium chloride, an addition reaction occurs at an appropriate temperature to produce vinyl acetylene. Then vinyl acetylene is added to hydrogen chloride under the catalysis of cuprous chloride, and 2-chloro-1,3-butadiene can be formed. This method requires strict control of the reaction conditions, especially the amount of catalyst and reaction temperature, to ensure that the reaction proceeds in the direction of the target product.

Many of the above methods for synthesizing 2-chloro-1,3-butadiene have their own advantages and disadvantages. In actual production, it is necessary to comprehensively consider the cost of raw materials, the difficulty of controlling the reaction conditions, the purity and yield of the product, and choose the most suitable synthesis route.

First, it is necessary to check the properties of this substance. 2-%E6%B0%9F%E8%8B%84%E5%9F%BA%E6%B0%B0 is an organic compound, flammable, mixed with air or into an explosive mixture. When using, be sure to avoid open flames and hot topics to prevent the risk of deflagration.
Second, pay attention to its impact on the human body. This substance may have irritating effects on the eyes, respiratory tract and skin. If inadvertently touched, rinse with plenty of water immediately when touching the eyes, and delay medical treatment; skin contact should also be quickly washed with soap and water; if inhaled, quickly leave the scene to a fresh air place, if unwell, seek medical attention.
Furthermore, properly store this substance. It should be stored in a cool and ventilated place, away from fire and heat sources, and the storage temperature should not exceed 37 ° C. It should be stored separately from oxidants and edible chemicals, and should not be mixed. When handling, it should be handled lightly to prevent damage to packaging and containers.
In addition, in the use environment, ensure good ventilation. Ventilation equipment can be installed to reduce its concentration in the air and reduce potential hazards. When operating, the operator should have professional knowledge and skills, operate according to regulations, and wear appropriate protective equipment, such as gas masks, protective gloves, etc.
Last, be familiar with emergency treatment methods. In the event of a leak, quickly evacuate the personnel from the leaked contaminated area to the safe area, and prohibit unrelated personnel from entering. Emergency responders wear self-contained positive pressure breathing apparatus and anti-toxic clothing to cut off the source of leakage as much as possible. Small leaks are adsorbed or absorbed with sand or other non-combustible materials; large leaks are built embankments or dug for containment, covered with foam, to reduce steam disasters, and transferred to a tanker or special collector with an explosion-proof pump for recycling or transportation to a waste treatment site for disposal.
