Storage method

Storage Precautions[13] Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The packaging must be sealed and protected from moisture. Respond to oxygenStore chemicals, alkalis, and food chemicals separately, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

Prepared from the reaction of phenylacetic acid and thionyl chloride. Mix equal moles of phenylacetic acid and spicy thionyl chloride and react at room temperature to release sulfur dioxide and hydrogen chloride gas. When a large amount of gas is no longer released, heat the reaction mixture to 30-40°C, keep it warm for 25 hours, and add a quarter of the volume of benzene to the mixture. Use low-temperature distillation to remove volatile substances, and gradually reduce the pressure to 0.133kPa. After all volatile substances are removed, steam out the 55-57°C (0.133kPa) fraction, which is phenylacetyl chloride. The yield is 80-85%.

Purpose

1. Used in spice preparation, organic synthesis, and also used as experimental reagents. [14]
