Application and Production Method of Myristyl Alcohol

1-Tetradecanol, or myristyl alcohol, is a straight-chain saturated fatty alcohol. A white waxy solid, almost insoluble in water, soluble in ether, and slightly soluble in ethanol.

Tetradecyl alcohol production method:

The basic principle of the production method of myristyl alcohol: it is prepared by hydrogenation reaction of tetradecyl carbonic acid in the presence of a catalyst.

1. High pressure hydrogenation method:

Coconut oil is continuously hydrogenated in a copper chromium catalyst to obtain a C8-C18 mixed alcohol. Glycerin in oil is hydrogenolyzed to isopropanol and water. Mixed fatty alcohols are often pressure-distilled to remove moisture and isopropanol, and then vacuum-distilled to cut C8-C10 alcohols, C12-C14 alcohols and C16-C18 alcohols.

2. Esterification hydrogenation method:

Coconut oil is transesterified with methanol in the presence of sulfuric acid to produce methyl laurate and glycerin, which is obtained by catalytic hydrogenation and distillation.

3. Hydrogenation of Myristic Acid:

a. Starting with Myristic Acid: Myristic acid, a fatty acid derived from natural sources like coconut oil or palm kernel oil, can be used as a starting material. It undergoes hydrogenation in the presence of a suitable catalyst, typically a metal catalyst such as nickel or palladium, under controlled temperature and pressure conditions.

b. Hydrogenation Process: The myristic acid is dissolved or dispersed in a suitable solvent, and hydrogen gas is bubbled through the mixture in the presence of the catalyst. The reaction proceeds and the unsaturated bonds of myristic acid are selectively hydrogenated, converting it into Myristyl Alcohol.

c. Purification and Isolation: After the completion of the hydrogenation reaction, the mixture is typically subjected to purification steps such as filtration, distillation, and crystallization to obtain pure Myristyl Alcohol. The specific purification processes may vary based on the desired purity level and the intended application’s requirements.

4. Ziegler Process:

The Ziegler process involves the hydroformylation of 1-dodecene, followed by hydrogenation to yield Myristyl Alcohol. This process utilizes a combination of a transition metal catalyst, such as cobalt or rhodium, and a suitable ligand to facilitate the hydroformylation and hydrogenation reactions. The hydroformylation step converts 1-dodecene into an aldehyde, which is subsequently hydrogenated to yield Myristyl Alcohol.

Tetradecyl alcohol applications:

Myristyl Alcohol, also known as tetradecyl alcohol or 1-tetradecanol, has various applications across different industries. Here are some common uses and applications of Myristyl Alcohol:

1. Tetradecyl Alcohol is a modifier in the special fragrance of daily chemical essence, which is used to add wax fragrance. In addition, it is also an emulsifier, surfactant, and thickener. Therefore, the compound is actually a raw material related to the perfume industry and the daily chemical industry.

2. It is the main raw material for the production of sodium tetradecyl polyoxyethylene ether succinate monosulfonate and sodium tetradecyl polyoxypropylene ether succinate monoester sulfonate.

3. Cosmetics and Personal Care Products: Myristyl Alcohol is commonly used in the formulation of cosmetics and personal care products. It acts as an emollient, providing a smooth and soft feel to the skin and hair. It is often found in creams, lotions, moisturizers, hair conditioners, and other skincare and haircare products.

4. Surfactant and Emulsifier: Myristyl Alcohol can function as a co-emulsifier or co-surfactant in formulations, assisting in the stabilization of emulsions or foams. It helps to improve the texture, consistency, and overall performance of products like creams, lotions, and liquid detergents.

5. Solubilizer: Myristyl Alcohol can enhance the solubility of certain ingredients in formulations. It aids in dissolving lipophilic substances, enabling the incorporation of oil-soluble actives or fragrances into various products.

6. Lubricant and Thickener: Due to its lubricating properties, Myristyl Alcohol is used in the manufacturing of lubricants and greases. It can reduce friction and provide smoothness in various applications, including industrial lubricants, automotive lubricants, and metalworking fluids. It also acts as a thickener in certain formulations, contributing to the desired viscosity and consistency of products.

7. Textile and Leather Industries: Myristyl Alcohol is utilized in textile and leather processing. It can enhance the softness, flexibility, and drape of fabrics, making it suitable for applications like fabric softeners, textile conditioners, and leather treatments.

8. Industrial Applications: Myristyl Alcohol finds use in various industrial applications, such as in the production of surfactants, plasticizers, and chemical intermediates. It can also serve as a raw material for the synthesis of other compounds.
