Read： 592 Time：7months ago Source：Transform the World with Simplicity

Amygdalic acid is a common chemical, widely used in food, medicine and other fields. Its chemical synthesis method due to its toxicity and risk is large, so in the synthesis experiment need to pay special attention to the following matters:

1. experimental environment requirements
mandelic acid synthesis needs to be carried out in a strict laboratory environment, must be equipped with the necessary protective facilities, such as goggles, protective clothing and so on. Laboratory personnel need to receive professional training in the use of chemicals and strictly follow the operating procedures.

2. experimental operation skills
in the synthesis process of bitter almond acid, need to master the precise operation skills, to avoid unnecessary accidents. For the specific synthesis steps and chemical reaction conditions, sufficient pre-experimental preparation and experimental scheme design must be made.

3. waste liquid treatment
The synthesis of mandelic acid will produce a large amount of waste liquid, which contains toxic and harmful chemical waste liquid. The waste liquid must be handled in accordance with relevant laws, regulations and standards, and it is strictly forbidden to dump or discharge at will to avoid harm to the environment and human body.

4. Comprehensive evaluation after experiment
After the synthesis of mandelic acid, it is necessary to conduct a comprehensive comprehensive evaluation of the experimental process and results. Including whether there is any non-standard operation during the experiment, the accuracy and stability of the experimental results. Only in this way can we better sum up the experience and lessons, and provide reference for future experimental work. The synthesis of

amygdalic acid is a complex and rigorous chemical experiment process, which requires laboratory personnel to strictly abide by the relevant operating procedures and safety procedures to ensure the smooth progress of the experiment and to ensure the safety of laboratory personnel and laboratory facilities.
