What are the physical properties of isobutyl isobutyl acetate?
Isobutyl Acetate is an organic compound. It has various physical properties, as detailed below.
Looking at its properties, it is a colorless and clear liquid under normal circumstances. It shines brightly in the sun, just like jade liquid flowing, clear and free of impurities. Its taste is fragrant, fruity, and it is faint and pleasing to the nose.
When it comes to boiling point, it is between 118 and 119 ° C. When the temperature gradually rises, at this time, the liquid dissolves gas and rises. Its melting point is very low, about -98.9 ° C. If the environment is so cold, it will solidify.
The density is also its important physical property, about 0.87 g/cm ³, which is lighter than water. If it is placed in water, it will float on it, just like the floating water of oil, which is distinct.
In terms of solubility, this substance is slightly soluble in water, and only slightly soluble in water, just like a drizzle entering a lake, and its integration is limited. However, it can be miscible with organic solvents such as alcohols and ethers, such as a fish getting water, and the two blend seamlessly.
In addition, the vapor pressure of isobutyl isobutyrate is also worth it. At a certain temperature, it will slowly evaporate and emit its unique smell in the air. The relative density of its vapor is slightly heavier than that of air, so the volatile gas is mostly close to the ground, and if it is not careful, it is easy to accumulate in low-lying places.
The above are all the physical properties of isobutyl isobutyrate. Only by clarifying its properties can it be used in various fields such as chemicals and fragrances to achieve its function.
What are the precautions for Isobutyl Acetate during storage and transportation?
Isobutyl Acetate is an organic compound. During storage and transportation, many matters must be paid attention to.
First words storage. Its flammable nature, so it should be placed in a cool and ventilated warehouse. The temperature of the warehouse should be controlled within a reasonable range and should not be too high to prevent danger. It is the first priority to stay away from fire and heat sources. It is strictly forbidden to have open flames and smoking in the storage area. Because of its volatility, the warehouse should be well sealed to prevent gas leakage. At the same time, it should be stored separately from oxidizing agents, acids, alkalis, etc., and should not be mixed. It should be stored in contact with it or cause chemical reactions, which will cause danger. The storage area should also be equipped with suitable materials to contain leaks for emergencies.
As for transportation. Transport vehicles must meet safety standards and be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. During transportation, ensure that the container does not leak, collapse, fall or damage. When driving, avoid high temperature periods and densely populated places to prevent accidents caused by excessive temperature or accidental collisions. Escort personnel must be familiar with the characteristics of isobutyl isobutyrate and emergency treatment methods, and pay close attention to the condition of the goods during transportation. When loading and unloading, the operation should be light and light to avoid brutal operations, resulting in package damage and leakage.
In this way, during the storage and transportation of isobutyl isobutyrate, observe the above precautions to ensure safety.
What is the impact of isobutyl acetate on the environment?
Isobutyl Acetate is an organic compound. Its impact on the environment is of considerable concern.
If this compound escapes into the atmosphere, some of it will be decomposed by photochemical reactions. Because it is volatile, it can diffuse in the atmosphere. However, its chemical reaction in the atmosphere may generate other by-products, some of which may be harmful to air quality.
As for the water environment, if isobutyl isobutyl acid accidentally flows into rivers, lakes and seas, it is slightly soluble in water, partially or floating on the water surface, and partially or slowly settling. It may affect aquatic organisms in water, or interfere with the normal physiological functions of aquatic organisms, or change the physical and chemical properties of water bodies, thereby affecting the balance of the entire aquatic ecosystem.
In soil, if contaminated by isobutyl isobutyrate, it may be adsorbed by soil particles, affecting the pore structure and aeration of the soil. Some soil microorganisms may be inhibited by it, which affects the decomposition of organic matter and nutrient circulation in the soil, and may cause damage to soil fertility and ecological functions in the long run.
If isobutyl isobutyrate exists in large quantities in the environment, it may cause more serious damage to the surrounding environment due to its flammability or increase the risk of fire. Once a fire breaks out, it will be difficult to extinguish, and it will also cause more serious damage to the surrounding environment, such as generating a large amount of harmful smoke. Therefore, during its production, use and storage, precautions should be taken to minimize its adverse impact on the environment.
What are the methods for preparing isobutyl isobutyl acetate?
The preparation methods of isobutyl acetate include the following:
First, isobutyl acid and isobutyl alcohol are used as raw materials, and sulfuric acid is used as a catalyst. The esterification reaction occurs under heating conditions. The text says: "Isobutyl acetate can be formed by co-heating isobutyl acid and isobutyl alcohol with sulfuric acid as a medium." In this reaction, the catalytic efficiency of sulfuric acid is quite good, but there is a risk of corrosion to the equipment, and the subsequent treatment is complicated. It requires multiple processes such as acid removal, washing with water, and drying to obtain a pure product.
Second, acid ion exchange resin is used as a catalyst. This method has significant advantages. The ion exchange resin can be reused, has little corrosion to the equipment, and is easy to separate after the reaction. The process is as follows: "Put isobutyric acid and isobutanol in the reaction kettle, add acidic ion exchange resin, heat and stir to promote esterification." After the reaction is completed, the resin is filtered off, and the product is slightly treated to obtain relatively pure isobutyl isobutyrate.
Third, the enzyme catalysis method is used. Lipase and other catalysts are used to facilitate the reaction under mild conditions. This is a green and environmentally friendly method. The reaction conditions are mild, the selectivity is high, and the side reactions are few. Its properties are as follows: "Take isobutyric acid and isobutanol, add an appropriate amount of lipase, and wait for the reaction to complete at a suitable temperature and pH." However, the high cost of the enzyme and the harsh requirements on the reaction environment limit its large-scale application.
Fourth, the acyl chloride method. Isobutyric acid is first made into isobutyryl chloride, and then reacted with isobutanol. This way, the reaction rate is fast and the yield is quite high. The method is: "Isobutyric acid is treated with a chlorinating agent to obtain isobutyryl chloride, and then meets with isobutanol to form isobutyl isobutyrate." However, chlorinating agents are often corrosive and toxic, so caution is required during operation, and the hydrogen chloride gas produced by the reaction needs to be properly handled.
