What are the physical properties of 1,2-ethyldisulfonate disodium salt?
1% 2C2-dibutyl oxalate is an organic compound. Its physical properties are many, let me tell you one by one.
Looking at its properties, under room temperature and pressure, 1% 2C2-dibutyl oxalate is a colorless and transparent liquid, just like clear water, but with a unique state. Its smell is fragrant, like a spring flower, emitting strands of aroma, not pungent but refreshing.
As for the boiling point, it is about 240 degrees Celsius. This property allows it to change from liquid to gas at a specific temperature. If it is heated with fire, it can be seen to turn into curling blue smoke and rise up at this temperature.
The melting point is quite low, about minus 40 degrees Celsius. In such a low temperature environment, it solidifies from a flowing liquid to a solid state, like a river freezing in winter, and no longer flows flexibly.
Its density is less than that of water. If it is placed in one place with water, it will float on the water, just like a light boat floating on blue waves. And it is insoluble with water, the two are distinct and independent.
1% 2C2-dibutyl oxalate has good solubility in organic solvents, such as ethanol, ether, etc., and can be dissolved with it, just like fish and water, which can form a uniform mixed system.
In addition, its viscosity is moderate, and when it flows, it is not as thick and sluggish as syrup, nor as light and fast as water, so it has a just right state.
All these physical properties make 1% 2C2-dibutyl oxalate useful in many fields such as chemical industry, and it is an indispensable chemical substance.
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 matters need to be paid attention to.
First, it concerns the storage environment. This compound should be stored in a cool and ventilated warehouse. Due to high temperature, it may increase its volatilization and even cause danger. And the warehouse needs to be kept away from fire and heat sources to prevent combustion or even explosion due to open flames or high temperatures. The lighting, ventilation and other facilities of the warehouse must be explosion-proof, and all electrical equipment should also meet the explosion-proof requirements, so as to avoid accidents caused by electric sparks generated by electrical equipment. At the same time, it should be stored separately from oxidizers, acids, alkalis, etc., and must not be mixed. Because of its active chemical properties, contact with these substances, or chemical reactions occur, thereby endangering safety.
Second, in terms of transportation. Before transportation, ensure that the packaging is complete and well sealed. If the packaging is damaged and dibutyl oxalate leaks, it will not only cause material loss, but also may pollute the environment. If it encounters a fire source, it is more likely to cause a fire. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or damage. Transportation vehicles should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Summer transportation should be carried out in the morning and evening to avoid high temperature periods to prevent the pressure inside the vehicle from increasing due to excessive temperature, causing leaks and other accidents. During transportation, follow the specified route and do not stop in densely populated areas and places with open flames.
Furthermore, whether it is storage or transportation, operators need to undergo special training and strictly abide by the operating procedures. Storage managers should regularly inspect storage facilities and materials, and transportation personnel should also be familiar with possible risks and countermeasures during transportation, so as to ensure the safety of 1% 2C2-dibutyl oxalate during storage and transportation.
What is the production method of 1,2-ethyldisulfonate disodium salt?
The preparation method of 1% 2C2-dibutyl oxalate is obtained by esterification of glycolic acid and butanol as raw materials. The method is described as follows:
First take an appropriate amount of glycolic acid and place it in a clean reactor. Glycolic acid, also known as oxalic acid, is active and is the key starting material for the reaction. Then, measure butanol and slowly add it to the kettle. Butanol has the characteristics of alcohol and can be esterified with glycolic acid.
In order to make this reaction go smoothly, an appropriate amount of catalyst needs to be added. Common catalysts, such as concentrated sulfuric acid, can effectively speed up the reaction rate and make it easier to combine glycolic acid and butanol. However, when using concentrated sulfuric acid, it is necessary to operate with caution, because it is highly corrosive.
During the reaction process, the temperature needs to be precisely controlled. Generally speaking, maintaining the reaction system in an appropriate temperature range can ensure the efficient progress of the reaction. If the temperature is too low, the reaction rate is slow; if the temperature is too high, it may trigger side reactions and affect the purity of the product.
During the reaction, in order to promote the reaction to move in the direction of generating 1% 2C2-dibutyl oxalate, the method of continuously removing the water generated by the reaction can be used. The removal of water can be achieved by means of azeotropic distillation. In this way, it is beneficial to increase the yield of 1% 2C2-dibutyl oxalate.
After the reaction is completed, the product is often mixed with unreacted raw materials, catalysts and other impurities. A series of post-processing steps are required to purify the product, such as neutralization, washing with water, distillation, etc. After neutralization, the residual acidic catalyst can be removed; washing with water can remove impurities soluble in water; distillation can separate pure 1% 2C2-dibutyl oxalate according to the difference in the boiling point of each component.
After these steps, high purity 1% 2C2-dibutyl oxalate can be obtained. This is the method for preparing 1% 2C2-dibutyl oxalate commonly used today.
What are the effects of 1,2-ethyldisulfonate disodium salt on the environment?
The impact of 1% 2C2-dibutyl oxalate on the environment is quite complex. It is an organic compound, and if released in the environment, it will bear the brunt of water quality. If this ester flows into rivers, lakes and seas, it is difficult to dissolve in water or float on the water surface, hindering the gas exchange between water and the atmosphere, resulting in a decrease in the amount of dissolved oxygen in water, threatening the survival of aquatic organisms.
And it may be ingested by aquatic organisms, enriched by the food chain, accumulated in advanced organisms, affecting its growth, reproduction, and even causing its death. Furthermore, 1% 2C2-dibutyl oxalate also has residues in soil. It can change soil physical and chemical properties, affect soil microbial community structure and function, and interfere with soil ecosystem material cycle and energy conversion.
In addition, if it volatilizes into the atmosphere, or participates in photochemical reactions, it generates secondary pollutants, affects air quality, and threatens human health and ecological balance. However, it is also necessary to understand that the degree of its impact on the environment is related to many factors such as the release amount and the self-purification ability of the environment. If the release amount is small, the self-purification ability of the environment is strong, and the environment may recover after a certain period of time. However, a large amount of continuous emissions will definitely cause serious and lasting damage to the environment.
