L (+) -lactic acid is an important chemical substance, and its preparation method is very critical. In terms of raw materials, carbohydrates such as natural sugars and starches are often used as the starting point. The preparation process involves multiple fermentation methods, in which specific microorganisms, such as lactic acid bacteria, ferment carbohydrates into L (+) -lactic acid under suitable temperature, humidity and nutrient environments. In the reaction step, the microorganisms first ingest the raw materials and gradually convert them into lactic acid through a series of enzymatic reactions. In this process, it is very important to regulate the reaction conditions, such as pH value, temperature, dissolved oxygen, etc., which will affect the rate of lactic acid production and yield. As for the purification mechanism, after the fermentation broth is crude, it needs to go through multiple purification processes, such as filtration, ion exchange, concentrated crystallization, etc., to obtain high-purity L (+) -lactic acid products to meet the application needs of different fields.

L (+) -lactic acid is an important chemical. Its chemical reaction and modification are related to many fields.

Safety Operation Specifications for L(+)-Lactic Acid Products
L(+)-Lactic acid is an important organic compound widely used in food, medicine, chemical industry and many other fields. This safety operation specification is specially formulated to ensure its safe use and standardized operation.
1. Storage Safety
L(+)-Lactic acid should be stored in a cool and ventilated warehouse. Keep away from fire and heat sources, and the storage temperature should not exceed 30°C. Keep the container sealed and store it separately from oxidants and alkalis. Do not store them together. Firefighting equipment of corresponding types and quantities should be equipped. The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials. Because it has a certain degree of corrosiveness, if it is not stored properly, it may react with other substances, causing safety accidents.
2. Transportation Safety
During transportation, ensure that the container does not leak, collapse, fall or be damaged. It is strictly forbidden to mix and transport with oxidants, alkalis, edible chemicals, etc. During transportation, it should be protected from sunlight, rain and high temperature. The transportation vehicle should be thoroughly cleaned after transportation. Bumps and temperature changes during transportation may affect the stability of the product, so transportation conditions need to be strictly controlled.
3. Operation specifications
Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter-type gas masks (half masks), chemical safety glasses, acid- and alkali-resistant work clothes, and rubber acid- and alkali-resistant gloves. Avoid contact with oxidants and alkaline substances. Handle with care during transportation to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Hazardous substances may remain in empty containers. During operation, due to the chemical properties of L(+)-lactic acid, the slightest carelessness may cause harm to operators or cause environmental pollution and other problems.
4. Emergency treatment
If a leak occurs, the personnel in the leak contaminated area should be quickly evacuated to a safe area, isolated, and strictly restricted from entering and leaving. It is recommended that emergency response personnel wear self-contained positive pressure respirators and acid- and alkali-resistant work clothes. Do not directly contact the leak. Cut off the source of the leak as much as possible to prevent it from flowing into confined spaces such as sewers and drains. Small leakage: Mix with sand, dry lime or soda ash. You can also use a large amount of clean water to rinse, dilute the rinse water and put it into the wastewater system. Large leakage: Build a dike or dig a pit to block it. Use a tank truck or a special collector with a pump to transfer, recycle or transport it to a waste treatment site for disposal. Once a safety accident occurs, timely and correct emergency treatment can effectively reduce losses and harm.
Following the above safety and operating specifications can maximize the safety of L(+)-lactic acid products during storage, transportation and use, and promote the stable development of related industries.
