The manufacturing method
of 75 medical alcohol
in the field of chemical production raw materials, 75 medical alcohol is a widely used disinfectant, its main components are ethanol and water, of which the content of ethanol accounts for 75%. This concentration of alcohol has the best bactericidal effect, while retaining enough moisture so that it does not cause excessive dryness to the skin when used. The following is the manufacturing method of 75 medical alcohol.

1. Raw Material Preparation

Manufacturing 75 Medical Alcohol The main raw materials that need to be prepared are food grade ethanol and water. The concentration of ethanol is usually 95%, while the purity of water should be as high as possible to avoid introducing additional impurities.

2. mixing

mix 95% ethanol and purified water in a certain proportion to obtain 75% medical alcohol. The specific blending ratio is: 26.67 ml of purified water needs to be added for every 100 ml of 95% ethanol. This ratio can be accurately measured by calculation or using tools such as measuring cups.
the
3. is stirred evenly

the prepared mixture of ethanol and purified water is fully stirred to ensure that the two components are fully mixed and evenly. Stirring can be carried out by means of a stirrer or manual shaking.

4. filtering to remove impurities

after stirring may contain some impurities, so it is necessary to use a filter for filtering to remove impurities and suspended matter. The choice of filter should be determined according to the type and size of specific impurities.

5. bottling storage

will be filtered 75 medical alcohol into a clean and dry bottle, sealed storage. It should be noted that medical alcohol should be stored in a cool, dry and ventilated place, avoiding direct sunlight and high temperature.

above is the basic manufacturing method of 75 medical alcohol. In the actual production process, the following points need to be paid attention to:

1. Quality control of raw materials: It should be ensured that the ethanol and water used meet the food-grade standards and avoid the introduction of harmful substances.
2. Sanitation of the production environment: The production of medical alcohol needs to be carried out in a clean and hygienic environment to avoid product contamination.
3. Monitoring of the production process: It is necessary to monitor the entire production process to ensure that every step is carried out in accordance with the prescribed operation to ensure the quality of the product.

In short, the manufacture of 75 medical alcohol requires strict compliance with relevant production specifications and standards to ensure product quality and safety. At the same time, because alcohol is flammable and volatile, it is necessary to strengthen safety management in the production process to prevent accidents such as fire.
