Properties and stability
Avoid withStrong oxidants, strong acids, strong bases, water, alcoholsContact.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants and acids, 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
It is derived from the reaction of lauric acid and thionyl chloride. Add thionyl chloride dropwise to lauric acid and heat to 75℃, stirring reaction2h, then heat to 90℃, reflow 2h. The reaction mixture is then fractionated,
First evaporate excess thionyl chloride under reduced pressure, and then collect 146-150℃(2.13-2.27kPa) fraction is dodecanoyl chloride. The yield is about 80%.
Purpose
Used in pharmaceutical industry and organic synthesis.
