The preparation of barbiturates is an exercise that requires great care because barbiturates are a highly toxic chemical. In the preparation of barbiturates, the need to strictly follow the following precautions:

1. experimental environment
preparation of barbiturates experiments should be carried out in a specialized chemical laboratory, follow the laboratory's safe operating procedures and processes. The laboratory should be equipped with appropriate personal protective equipment, including goggles, lab clothes, gloves, etc.

2. equipment and reagent
in the preparation of barbital need to use high-quality experimental equipment and reagents to ensure the integrity of the equipment and the purity of the reagents. The selection of suitable reagents and equipment can reduce the risk of experimental operation.

3. operating procedures
in the process of operation, should strictly follow the operating procedures, shall not change the operating steps without authorization. The experimenter should be vigilant to prevent accidents during operation.

4. Waste treatment
After the completion of the experiment, the waste reagents and waste liquid need to be properly treated to avoid pollution to the environment.

In addition to the precautions in the preparation process, the correct use of barbiturates is also very important. The following is the correct use of barbital:

1. Storage
Barbital should be stored in a dry, cool place, avoid moisture and high temperature. At the same time, barbiturates should be stored in special storage cabinets to avoid mixing with other chemicals.

2. Use
When using barbital, it should be strictly in accordance with the experimental procedures and procedures, avoid contact with barbital skin and respiratory tract. The experimental operation should be careful and meticulous, and strictly follow the laboratory safety regulations.

3. Waste treatment
After using barbiturates, the waste reagents and waste liquid also need to be properly treated to avoid environmental pollution.

can effectively reduce the risk in experimental operation, protect the safety of experimental personnel, and protect the environment from pollution by strictly observing the precautions and correct use methods of preparing barbiturates. It is hoped that the experimenters will always keep in mind the principle of safety first during operation and work together for the safety environment of the laboratory.
