Properties and stability
Prohibited withStrong oxidizing agentContact.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. should be kept away from oxidizer, do not store together. It should not be stored for a long time to avoid deterioration. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
From 2-octene via 1-octane Alkyne to octyne carboxylic acid, and then esterified with methanol.
Purpose
It has a green floral effect and can be used with other spices in gardenia, tuberose, violet, osmanthus, rose and other flavors. It is also used in acacia compound, suxinlan and other ionone-containing formulas to enhance the aroma and give top notes. Used in trace amounts in food spices to imitate peach, banana, lychee, longan, cucumber, melon, currant and berry flavors.
