How to make alcohol
Alcohol (ethanol) is a common organic compound widely used in medical, disinfection, food and industrial fields. In recent years, with the increase in health awareness and the impact of the epidemic, the method of making alcohol has become a hot topic. This article will introduce in detail the production method, raw material selection and precautions of alcohol, and provide you with comprehensive guidance based on hot topics on the Internet in the past 10 days.
1. How to make alcohol
There are two main ways to make alcohol:FermentationandSynthesis. Here are the detailed steps for both methods:
| method | raw materials | steps |
|---|---|---|
| Fermentation | Sugar (such as sugar cane, corn, wheat, etc.) | 1. Crush the raw materials and add water to make a slurry; 2. Add yeast for fermentation to generate ethanol and carbon dioxide; 3. Purify ethanol by distillation. |
| Synthesis | Ethylene (petrochemical product) | 1. Ethylene and water react under the action of catalyst; 2. Generate ethanol; 3. Purify by distillation. |
2. Detailed process of producing alcohol by fermentation method
Fermentation is a commonly used method in home and small-scale production. Here are the specific steps:
| steps | Operation | Things to note |
|---|---|---|
| 1. Raw material preparation | Choose raw materials with high sugar content (such as sugar cane, corn, etc.) | Make sure the raw materials are not moldy, otherwise the fermentation effect will be affected. |
| 2. Crushing and saccharification | Crush the raw materials, add water, and heat to 60-70°C to promote saccharification. | Temperatures that are too high will destroy enzyme activity. |
| 3. Fermentation | Add yeast and ferment at 25-30℃ for 3-7 days | Maintain a closed environment to avoid bacterial contamination. |
| 4. Distillation | Heat the fermentation broth to about 78°C and collect ethanol vapor | Control the temperature to avoid mixing of impurities. |
3. The relationship between hot topics on the Internet in the past 10 days and alcohol production
The following are the hot topics related to alcohol on the Internet in the past 10 days, reflecting the public’s concerns about the production and use of alcohol:
| hot topics | Related content |
|---|---|
| Homemade disinfectant alcohol | During the epidemic, the demand for home-made alcohol increased, and fermentation methods became a popular search. |
| Environmentally friendly alcohol production | Use agricultural waste (such as straw) to make alcohol to reduce environmental pollution. |
| Application of alcohol fuel | As a clean energy source, the use of alcohol in automobile fuel has sparked discussions. |
4. Things to note when making alcohol
Here are some things to note when making alcohol to ensure safety and quality:
1.Safety first: Alcohol is flammable. Keep away from fire sources and maintain ventilation during the production process.
2.Raw material selection: Prioritize the use of fresh, pollution-free raw materials and avoid the use of moldy substances.
3.Fermentation control: Long fermentation time may cause rancidity, so regular inspection is required.
4.Distillation and purification: The distillation temperature needs to be accurately controlled, otherwise it may affect the alcohol purity.
5. Uses of alcohol
Alcohol has a wide range of uses and the following are its main areas of application:
| Purpose | Description |
|---|---|
| Medical disinfection | Alcohol with a concentration of 75% can effectively kill bacteria and viruses. |
| food industry | Used for wine making, condiment making, etc. |
| Industrial raw materials | As a solvent or chemical raw material, it is used in the production of coatings, cleaning agents, etc. |
Conclusion
Alcohol can be produced in a variety of ways, from fermentation to household and small-scale production, while synthesis is more commonly used in industry. Regardless of the method, attention needs to be paid to safety and quality control. Combined with recent hot topics, the application of alcohol in the fields of disinfection, environmental protection and energy has attracted much attention. I hope this article provides you with practical guidance.
