Properties and stability
Avoid contact with oxidants.
Storage method
Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging must be sealed and protected from moisture. should be kept away from oxidizer, do not store together. 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
Derived from bromination of tetradecanol. Add tetradecanol to the reaction pot, add sulfuric acid dropwise while stirring, and continue stirring for half an hour after the addition. Then add hydrobromic acid, heat to 99-101°C, and react for 8 hours. Cool to 30°C, stop stirring, and leave for 12 hours. Separate the upper oily substance and adjust the pH to 8 with 10% sodium carbonate solution. Separate the water layer, wash the oil twice with an equal volume of 50% ethanol, add sodium carbonate to the washed oil, stir intermittently, and dry for 24 hours. Filter to get the finished product.
Purpose
Organic synthesis intermediates.
