1-What are the chemical properties of Chlorooctadecane?

1-Chloroctadecane, its shape is colorless to light yellow liquid, insoluble in water, miscible in organic solvents such as alcohols and ethers. This substance has the dual properties of alkanes and halogenated hydrocarbons.
In terms of the characteristics of alkanes, its chemical properties tend to be stable at high temperatures or light. Due to the high bond energy of C-H, it is not easy to be broken by general reagents, so it is difficult to react with strong acids, strong bases and strong oxidants at room temperature. However, under the conditions of high temperature, light or catalyst, free radical substitution reactions can occur. If it encounters chlorine gas under light, chlorine atoms will replace hydrogen atoms on the alkane chain to form a variety of chlorinated products.
In terms of the properties of halogenated hydrocarbons, the electronegativity of the chlorine atom in 1-chloroctadecane is greater than that of carbon, resulting in the polarity of the C-Cl bond. This polarity makes the bond active to a certain extent, and nucleophilic substitution can occur. Treated with an aqueous solution of sodium hydroxide, the chlorine atom will be replaced by a hydroxyl group to form octadecyl alcohol; if reacted with sodium cyanide in an appropriate solvent, the chlorine atom will be replaced by a cyanide group, and the product is nineteen nitrile, which can be hydrolyzed to obtain octadecyl acid. In addition, in a strong alkali alcohol solution, 1-chloroctadecane can also undergo a elimination reaction to eliminate hydrogen chloride and form oc

What is the synthesis method of 1-Chlorooctadecane?

1-Chloroctadecane is also an organic compound. There are two common methods for its synthesis.
First, it is obtained by reacting octadecyl alcohol with a chlorination reagent. In the past, thionyl chloride was often used as a chlorination agent. Octadecyl alcohol and thionyl chloride are co-placed in a reactor under suitable conditions. The kettle needs to maintain an appropriate temperature, usually in a state of mild heating, about 50-80 degrees Celsius. During this reaction, thionyl chloride reacts with the hydroxyl group in the octadecanol, and the hydroxyl group is replaced by a chlorine atom, resulting in the escape of 1-chloroctadecane with sulfur dioxide and hydrogen chloride gas. The reaction formula is roughly as follows: C H < unk > OH + SOCl < unk > → C H < unk > < unk > Cl + SO < unk > ↑ + HCl < unk >. The advantage of this reaction is that the yield is quite high, and the reaction conditions are relatively mild and easy to control. However, thionyl chloride has an irritating odor and is corrosive. It must be handled with caution and protective measures must be taken.
Second, octadecane is used as the raw material and is prepared by halogenation reaction. Chlorine is often used as the halogenating agent, and it is carried out under the action of light or initiator. Octadecane is placed in the reactor, and chlorine gas is introduced. At the same time, light is applied or initiators such as benzoyl peroxide are added. The role of light or initiator is to make chlorine molecules produce chlorine free radicals, and then undergo free radical substitution reaction with octadecane to generate 1-chlorooctadecane. However, the selectivity of this reaction is not good, in addition to generating the target product, it will also produce by-products such as polychlorinated substitutes. To improve the selectivity, it is necessary to finely control the reaction conditions, such as strict control of the amount of chlorine, reaction temperature, and light intensity.
The process of synthesizing 1-chlorooctadecane, regardless of the method used, requires attention to the precise control of the reaction conditions, the purity of the raw material, and the separation and purification of the product, in order to obtain a more pure 1-chlorooctadecane.

1-What are the precautions for Chlorooctadecane during storage and transportation?

1-Chlorooctadecane is also an organic compound. During storage and transportation, all precautions are essential.
When storing, the first choice of environment. When placed in a cool, ventilated warehouse, away from fires and heat sources. The cover is flammable, and it may cause combustion in case of open flames or hot topics. The temperature of the warehouse should be strictly controlled to prevent its chemical properties from changing due to excessive temperature. In addition, it should be stored separately from oxidants and alkalis, and must not be mixed. Because 1-chlorooctadecane comes into contact with oxidants or causes violent chemical reactions, it endangers safety.
Packaging should not be ignored. It is necessary to ensure that the packaging is well sealed to prevent its volatilization and leakage. The packaging materials used should be corrosion-resistant to resist the erosion of 1-chloroctadecane.
As for transportation, the transportation vehicle must be equipped with the corresponding variety and quantity of fire protection equipment and leakage emergency treatment equipment. During driving, it is necessary to prevent exposure to the sun, rain and high temperature. The tank (tank) car used during transportation should have a grounding chain, and holes can be set in the tank to baffle to reduce shock and generate static electricity. It is strictly forbidden to mix with oxidants, alkalis, etc. During transportation, it should be driven according to the specified route, and do not stop in residential areas and densely populated areas. When loading and unloading, it should be handled lightly to prevent damage to packaging and containers. Therefore, the safety of 1-chloroctadecane during storage and transportation is guaranteed.
