What are the physical properties of Sec-butyl Alcohol?
Second butanol, its mild nature, is a colorless and transparent liquid. It has a special fragrance and a fragrant smell. Its boiling point is moderate, about 100.3 ° C, so it can evaporate slowly at ordinary temperatures. Its melting point is low, -114.7 ° C, so it is a liquid at room temperature, which is quite stable.
The density of second butanol is lighter, about 0.808g/cm ³, which is slightly lighter than water. If it is juxtaposed with water, it can float on the water surface. Its solubility is unique, it can be freely miscible with organic solvents such as alcohols and ethers, and it can also be partially miscible with water. It is often used as an excellent solvent in organic synthesis.
In addition, sec-butanol is flammable, and it is very easy to burn in case of open flames and hot topics. When burning, the flame is bright and accompanied by a large amount of heat release. Its steam and air can form an explosive mixture, and there is a danger of explosion in case of fire. Therefore, when storing and using, it is necessary to take precautions and keep away from fire and heat sources to ensure safety.
What are the chemical properties of Sec-butyl Alcohol?
Sec-butanol is an organic compound whose molecule contains hydroxyl groups and has unique chemical properties.
Sec-butanol has typical reaction characteristics of alcohols. First, esterification reaction can occur. When encountering carboxylic acid, under suitable catalyst and conditions, the hydrogen in the hydroxyl group and the hydroxyl group in the carboxylic acid group combine to form water, and the rest are connected to form esters. This reaction is widely used in the preparation of fragrances, plasticizers and other fields. By reacting sec-butanol with different carboxylic acids, various ester compounds can be obtained.
Second, sec-butanol can dehydrate. Depending on the reaction conditions, different products can be formed. If concentrated sulfuric acid and heating conditions, intramolecular dehydration forms butene. Due to the specific molecular structure of sec-butanol, 1-butene or 2-butene can be formed during dehydration. The specific product ratio is affected by the reaction conditions. If the reaction conditions are mild, sec-butanol can also undergo intermolecular dehydration to form ethers.
Third, sec-butanol is easily oxidized. Under the action of an appropriate oxidant, the hydroxyl group of sec-butanol is first oxidized to a carbonyl group to form butanone. This reaction is commonly used in the preparation of ketone compounds in organic synthesis. In addition, sec-butanol can react with active metals such as sodium, and the hydrogen in the hydroxyl group is replaced by sodium to generate hydrogen and sodium alcohol. This reaction can be used to prepare specific sodium alcohol compounds, which also reflects the activity of sec-butanol hydroxyl groups. In conclusion, sec-butanol has a variety of chemical reactivity due to the presence of hydroxyl groups in its molecular structure, and plays an important role in many fields of organic synthesis and chemical production.
What are the production methods of Sec-butyl Alcohol?
For sec-butanol, there are three ways to prepare it.
One is hydrated from butene. Among them, butene includes cis, trans-2-butene and 1-butene. Sulfuric acid or solid acid is used as the catalyst to add butene to water. When sulfuric acid is used as the catalyst, butene is passed into the sulfuric acid solution, and sec-butanol is obtained through reaction and hydrolysis. Although the yield of this process is acceptable, sulfuric acid is corrosive, which requires high equipment, and the subsequent treatment is complicated, which is prone to a large amount of waste acid, which is not conducive to environmental protection. While solid acid catalysts such as ion exchange resins overcome the drawbacks of sulfuric acid, the reaction conditions are mild and easy to separate, but there are problems such as easy degradation of activity.
The second is acetaldehyde acetation. Under the action of specific catalysts such as alkali catalysts, two-molecule acetaldehyde is condensed with hydroxyaldehyde to obtain 3-hydroxybutyraldehyde, and then reduced to sec-butanol by hydrogenation. This way, the raw material acetaldehyde comes from a wide range of sources, the reaction conditions are relatively mild, there are few side reactions, and the product purity is high. However, the process is long, and the equipment and operation requirements are fine. The catalyst needs to be replaced and regenerated in a timely manner.
The third is the fermentation method. Biomass such as starchy raw materials (corn, potatoes, etc.) or sugars are used as substrates. After microbial fermentation, the enzyme system in the microorganism converts the substrate into sec-butanol. This is a green and environmentally friendly method. The raw materials are renewable and in line with the concept of sustainability. However, the fermentation process is prone to bacteria, the fermentation cycle is long, the product concentration is low, and subsequent separation and purification are difficult and costly.
What are the precautions when using Sec-butyl Alcohol?
For sec-butanol, when using it, all kinds of things should be paid attention to.
First, it is related to the risk of ignition and explosion. This is a flammable material, and its vapor and air can form an explosive mixture. In case of open flame, high heat can ignite and detonate. When using, be sure to keep away from fire and heat sources, and smoke is strictly prohibited in the workplace. Explosion-proof ventilation systems and equipment are required to prevent steam leakage into the air in the workplace. When handling, it should also be handled lightly to prevent damage to packaging and containers.
Second, it involves health hazards. Sec-butanol has irritating effects on the eyes, nose, throat and other mucous membranes. Inhalation, ingestion or absorption through the skin may be harmful to the body. When using, take good protective measures. Operators should wear self-priming filter gas masks (half masks), chemical safety glasses, anti-static work clothes, and rubber oil-resistant gloves. If you accidentally come into contact with the skin, you should immediately take off the contaminated clothes, rinse the skin thoroughly with soapy water and water; if it splashes into the eyes, lift the eyelids quickly, rinse thoroughly with a lot of flowing water or normal saline for at least 15 minutes, and seek medical attention in time.
Third, pay attention to storage conditions. It should be stored in a cool and ventilated warehouse. The storage temperature should not exceed 37 ° C, and keep the container sealed. It should be stored separately from oxidants and acids, and should not be mixed. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
Fourth, during use, the volatile gas should be properly handled. Because it has a certain odor and is harmful, it is necessary to ensure good ventilation, or use ventilation equipment to discharge the volatile gas, so as not to accumulate in a limited space and cause danger.
In short, the use of sec-butanol should be treated with caution in many aspects such as explosion prevention, health protection, storage and placement, and gas treatment, and follow the norms to ensure safety.
