Dodecanol is a monohydric alcohol produced from coconut oil to lauric acid and then catalytically hydrogenated. The following suppliers of dodecanol will give you a detailed understanding:
1. Physical and chemical properties:
Yellow oily liquid or solid with pungent odor. Combustible. Melting point 26℃ (24℃), boiling point 255-259℃, 192℃ (13.3kPa), 150℃ (6.67kPa), 134.7℃ (1.33kPa), relative density 0.8309 (24/4℃), refractive index 1.4428, flash Point >100℃, soluble in ethanol (1 part lauryl alcohol dissolved in 2 parts 70% ethanol) and ether, insoluble in water. Has a floral scent.
Second, production method:
1. High-pressure hydrogenation: Coconut oil is continuously hydrogenated in a copper-chromium catalyst to obtain a C8-C18 mixed alcohol. The glycerin in the oil is hydrogenolyzed into isopropyl alcohol and water. After the mixed fatty alcohols are frequently pressure evaporated to remove the water and isopropyl alcohol, C8-C10 alcohols, C12-C14 alcohols and C16-C18 alcohols are distilled under reduced pressure.
2. Esterification and hydrogenation method: Coconut oil reacts with methanol in the presence of sulfuric acid to produce methyl laurate. and glycerol, through catalytic hydrogenation and distillation to obtain lauryl alcohol.
3. Purpose:
1, used to manufacture high-efficiency detergents, surfactants (sodium fatty alcohol ether sulfate, K12, AEO, etc.), foaming agents, and emulsifiers agents, milk selection agents, textile oil agents, fungicides, cosmetics, plasticizers, plant growth regulators, lubricant additives and other specialty chemicals.
2, widely used in light industry, chemical industry, metallurgy, medicine and other industrial products.
3. Dodecanol has the aroma of moonflower and violet, and can be used in rose, violet and lily-narcissus flavors. middle.
4. It has stable chemical and physical properties and is safe to use in soap fragrance.
5. N-dodecaldehyde can be obtained by oxidation or dehydrogenation.
6. Used as raw materials for cosmetics, fragrances, textile auxiliaries, chemical fiber oils, emulsifiers and flotation agents.
7. Some surfactants of dodecanol derivatives are also disinfectants. </span
