Tetrahydrofuran (THF) is a common organic synthesis solvent, which is widely used in chemical laboratories and industrial production. When using tetrahydrofuran, we need to pay special attention to some operating matters and skills to ensure the safety and efficiency of the operation.
attention should be paid to its volatility and flammability when using tetrahydrofuran
. Therefore, it is necessary to maintain good ventilation during operation, avoid static electricity, and stay away from open flames and high temperature sources. When storing tetrahydrofuran, it should be placed in a cool and dry place, away from fire and oxidizing agents to prevent accidents.

tetrahydrofuran is irritating to skin and mucous membranes, protective gloves and goggles must be worn during operation to avoid direct contact with skin and eyes. When accidental contact occurs, rinse immediately with plenty of water and seek medical help.

In addition, tetrahydrofuran is very sensitive to oxygen and moisture in the air, so desiccant and sealing measures must be taken during operation and storage to prevent moisture from entering and affecting its performance.

When handling tetrahydrofuran, care must be taken to avoid the generation of gases, vapors or mist and to minimize the contact time. When using tetrahydrofuran for dissolution, filtration and evaporation, appropriate equipment and operating conditions should be selected to ensure safe and efficient operation. When tetrahydrofuran is in contact with a strong oxidant or a strong acid-base substance, reaction or heat may occur, so corresponding protective measures need to be taken according to the specific situation.
Tetrahydrofuran after
use shall be safely disposed and discarded, and shall not be directly discharged into the environment, and shall be properly disposed of in accordance with relevant laws and regulations.

Tetrahydrofuran is a commonly used organic synthesis solvent. Special attention should be paid to its volatility and flammability, irritation, sensitivity to moisture, and incompatibility with other chemicals when used to ensure safe operation. And efficient. When operating tetrahydrofuran, be sure to follow the relevant operating procedures and safety measures to protect yourself and the surrounding environment.
