What are the physical and chemical properties of 1,2-ethyldisulfonate disodium salt?
1% 2C2-dibutyl oxalate is an organic compound. Its physical and chemical properties are as follows:
Looking at it, this is a colorless and transparent liquid with a fragrant smell, similar to the fragrance of flowers and fruits. It exists stably at room temperature and pressure.
When it comes to solubility, it is difficult to dissolve in water, but it is miscible with organic solvents such as ethanol and ether. This property is just like the incompatibility of oil and water, but it is like a duck to water with similar organic solvents and can blend with each other.
The boiling point is about 252 ° C, and the melting point is -32 ° C. The high boiling point indicates that more heat is required to boil it into a gaseous state; the low melting point means that it can still maintain a liquid state at lower temperatures.
Relative density (water = 1) is about 0.986 (20 ° C), slightly lighter than water, just like wood floats in water, and this substance can also float on water.
Its flash point is about 110 ° C, and it is flammable in case of open fire and hot topic. This flash point value warns people to keep away from fire sources and beware of fire when using and storing.
In terms of chemical properties, hydrolysis can occur. Under the condition of acid or base as catalyst, dibutyl oxalate reacts with water to form oxalic acid and butanol. This hydrolysis reaction is like disassembling a complete substance into several parts. It can also participate in the reverse reaction of esterification reaction, and recombine with alcohols under specific conditions to form new ester compounds.
In addition, substitution reactions can also be carried out, and some atoms or atomic groups in the molecule can be replaced by other atoms or atomic groups, just like material exchange, to form other products. This is an important physical and chemical property of 1% 2C2-dibutyl oxalate.
What is the preparation method of 1,2-ethyldisulfonate disodium salt?
The preparation method of 1% 2C2-dibutyl oxalate is really the key to chemical industry. The method is as follows:
First, the raw materials need to be prepared, and oxalic acid and n-butanol are indispensable. For oxalic acid, it is colorless and crystalline, and it is active; n-butanol is a colorless and transparent liquid with a special odor. Both should be pure to ensure a smooth reaction.
Then, in a clean reactor, add oxalic acid and n-butanol in a certain ratio. Usually, the amount of n-butanol is slightly more than that of oxalic acid, because it can promote the reaction in the direction of forming esters.
Subsequently, add an appropriate amount of catalyst. Sulfuric acid is often the first choice, which can accelerate the reaction rate, but the amount needs to be carefully controlled, too much is easy to cause side reactions.
Then, the temperature rise to make the reaction system reach a suitable temperature. Generally speaking, it needs to be maintained between 110-130 ° C. At this temperature, oxalic acid and n-butanol can react effectively. After the process of esterification, 1% 2C2-dibutyl oxalate and water are produced.
When reacting, it should be fully stirred to allow the reactants to be evenly mixed to ensure a comprehensive and rapid reaction. At the same time, a reflux device needs to be set up to allow the volatile reactants to condense and reflux to reduce the loss of raw materials.
After the reaction is completed, the reaction solution is cooled. After that, the separation funnel is used to separate, and the lower aqueous phase is discarded. The organic phase is washed successively with saturated sodium carbonate solution and water to remove unreacted acids and catalysts and other impurities.
Finally, the washed organic phase is purified by distillation. Collect fractions in a specific boiling point range, which is pure 1% 2C2-dibutyl oxalate. Through this method, high-purity products can be obtained to meet the needs of chemical industry.
What are the precautions for the storage and transportation of 1,2-ethyldisulfonate disodium salt?
1% 2C2-dibutyl oxalate is an organic compound. When storing and transporting, many points need to be paid attention to.
In terms of storage, the first environmental choice. When placed in a cool and ventilated warehouse, the substance is dangerous due to heat. The temperature of the warehouse should not be too high to prevent it from volatilizing, decomposing or triggering other chemical reactions. And it must be kept away from fire and heat sources. Because 1% 2C2-dibutyl oxalate is flammable, it can cause combustion and explosion in case of open flame, hot topic or.
Furthermore, the storage should keep the container sealed. If the container is not sealed, the substance may evaporate into the air, which will not only damage the material, but also cause environmental pollution, and volatile gases or form explosive mixed gases, increasing safety risks.
In addition, it needs to be stored separately from oxidants, acids, alkalis, etc., and must not be mixed. Due to its chemical properties, contact with these substances or severe chemical reactions may occur, resulting in accidents.
When transporting, the packaging must be sturdy. To ensure that the packaging is not damaged or leaked during transportation, the commonly used packaging materials and methods must meet relevant safety standards.
Transportation vehicles must also meet safety requirements and be equipped with corresponding fire equipment and leakage emergency treatment equipment. During transportation, drivers and escorts need to pay close attention to avoid violent bumps and collisions in vehicles to prevent material leakage due to damaged packaging.
In the event of a leak, emergency measures should be taken immediately. Evacuate surrounding personnel, strictly prohibit fire from approaching, and quickly plug and clean up the leak to prevent its spread from causing greater harm. In this way, the safety of 1% 2C2-dibutyl acetate during storage and transportation must be ensured.
What are the effects of 1,2-ethyldisulfonate disodium salt on the environment?
1% 2C2-dibutyl oxalate is a common organic compound in the chemical industry. The environmental impact of this substance is quite complex and multi-faceted.
In the aquatic ecological environment, if it accidentally flows into the water body, it will float on the water surface because it is difficult to dissolve in water, hindering the gas exchange between the water body and the atmosphere, and affecting the respiration of aquatic organisms. And its degradation is slow, and it exists in the water body for a long time, which will cause deterioration of water quality and interfere with the normal growth and reproduction of aquatic organisms. If some aquatic organisms ingest food containing this substance or absorb this substance in the water, it will accumulate in the body, pass through the food chain, and cause toxicity to higher organisms, affecting the balance of the entire aquatic ecosystem.
In the soil environment, if it enters the soil, it will change the physical and chemical properties of the soil. It will adsorb on the surface of soil particles, hinder soil pores, affect soil aeration and water permeability, and is not conducive to plant root growth and nutrient absorption. At the same time, it will inhibit the activity of microorganisms in the soil, interfere with the decomposition of organic matter in the soil and nutrient circulation, and then affect soil fertility and ecological functions.
In the atmospheric environment, although the volatility is relatively weak, under certain conditions, such as high temperature or strong ventilation, a small amount of volatilization enters the atmosphere. This substance will participate in photochemical reactions in the atmosphere, generate secondary pollutants, such as ozone, etc., aggravate air pollution, affect air quality, and cause irritation and damage to the human respiratory system and eyes.
In summary, although 1% 2C2-dibutyl oxalate is a common compound, its potential threat to the environment should not be underestimated. Strict prevention and control are required during production, use and disposal to reduce the harm to the environment.
