How to make 10% acetic acid? Explain the production process of acetic acid in detail

acetic acid, as an important chemical raw material, is widely used in food, medicine, textile and other industries. Acetic acid is commonly used in many industries and households, and in some specific application scenarios, the concentration of acetic acid needs to reach about 10%. How to make 10% acetic acid? This article will analyze the process, raw materials and steps of making acetic acid in detail to help you fully understand this process.

1. Definition and Application of Acetic Acid

acetic acid (chemical formula: CHYCOOH), also known as acetic acid, is a common organic acid. In industrial production, acetic acid usually exists in the form of concentrated solution, the concentration is generally above 99%, while the concentration of vinegar used in households is generally about 4% to 7%.

How to make 10% acetic acid is actually to dilute the high concentration of acetic acid to the required concentration. Acetic acid in the food industry is often used as a sour agent, preservative, it is also the production of acetate, acetate, plastics, medicine and other products of the basic raw materials.

2. Acetic acid production raw materials

the raw materials for the manufacture of acetic acid are mainly ethylene or ethanol. Ethanol produces acetic acid by catalytic oxidation, and can also be prepared by the reaction of ethylene with water. The industrial production of acetic acid is mostly carried out by the following two methods:

• methanol method: Methanol and carbon monoxide react with a catalyst to produce acetic acid.
• ethanol method oxidation of ethanol in air produces acetic acid.

Both of these methods can effectively produce high concentrations of acetic acid, and we focused on how to dilute these higher concentrations of acetic acid to the target concentration of 10%.

3. Dilution process of acetic acid

the key to how to make 10% acetic acid is to dilute the higher concentration acetic acid solution to 10% by adding water. The dilution process requires the following steps:

• choose the right concentration: First, it is necessary to determine the concentration of the raw material acetic acid solution, usually the concentration of industrial acetic acid solution is about 99%.
• Calculate the amount of water needed: According to the concentration dilution formula, determine how much water needs to be added. For example, if you use 99% acetic acid, to dilute it to 10%, you can use the following formula: [ C 1V1 = C 2V2 ] Where, C is the original acetic acid concentration, V is the original acetic acid volume, C is the target concentration, and V is the target volume. According to this formula, the amount of water that needs to be added can be calculated.
• Mixing and stirring: Mix the acetic acid and water thoroughly, and ensure that the two are evenly mixed by stirring to reach the required 10% concentration.

4. Precautions

in the process of how to make 10% acetic acid, there are some matters that need special attention:

• use the right water.: In order to ensure the purity of acetic acid, it is best to use deionized water or distilled water to dilute.
• Safety measures: Although acetic acid is widely used, its strong acid nature makes it necessary to pay attention to safety during operation. Operators should wear protective goggles, gloves, and dilute in a well-ventilated environment.
• Storage conditions: The diluted 10% acetic acid should be stored in an acid-resistant container to avoid reaction with metal materials. Avoid direct sunlight and store in a cool and dry place.

5. Summary

through the above analysis, the production of 10% acetic acid is actually a simple dilution process, only need to be a higher concentration of acetic acid and water mixed in a certain proportion. In actual operation, it is very important to master the correct calculation method and dilution ratio, and at the same time pay attention to the safety of operation to ensure the smooth progress of the production process.

The answer to the question of how to make 10% acetic acid is actually to understand the concentration and dilution principle of acetic acid, and to make the ratio in a scientific and reasonable way. It is hoped that the detailed analysis of this article can help you understand the production and dilution process of acetic acid more clearly and successfully complete the relevant operations.
