Properties and stability
1. Avoid contact with oxidants, acidic chlorides, and acid anhydrides. It has the chemical reactivity of higher primary alcohols.
2. Exist in smoke.
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. They should be stored separately from oxidants, acidic chlorides, and acid anhydrides, 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
The mixed alcohol is obtained by methyl esterification and high-pressure hydrogenation of coconut oil, and then the product is obtained by fractional distillation. It can also be produced by the Ziegler method of ethylene oligomerization, oxidation and hydrolysis.
It can be isolated from spermaceti and whale oil or catalytically reduced with their corresponding acids and esters. Depending on the conditions and prices of industrial production, the application of high-pressure hydrogenation or lithium-aluminum hydride reduction should be considered. .
Purpose
Myristol is a modifier in the special fragrance of daily chemical fragrances to add a waxy aroma. In addition, it is also an emulsifier, surfactant and thickener, so this compound is actually used in the fragrance industry and daily chemical industry. Related raw materials. Used in the manufacture of tetradecyl mercaptan and detergents, etc. It can be used as raw material for organic synthesis and surfactants. Can also be used as a cream softener.
