About Octadecylamine ethoxylate ether  :

Chemical structure: The chemical structure of octadecyl ethoxy ether comprises octadecyl, ethoxy and amine groups. Its molecular formula is C20H41NO.

Physical state and appearance: Stearamine ethoxy ether is a light yellow to yellow oily liquid with a slight odor. Its freezing point is low, its boiling point is high, and its relative density is greater than water's.

Solubility: Stearamine ethoxy ether has good water and oil solubility and can be dissolved in various organic solvents. It can produce significant surface-active effects at low concentrations.

Surface activity: Due to its molecular structure containing both long-chain alkyl and aminoethoxy, stearine ethoxy ether has excellent surface activity. 

Stability and oxidation resistance: Stearamine ethoxy ether is relatively stable at room temperature and is not easily hydrolyzed and oxidized. However, its stability may be affected under strong acid or base conditions. Under conditions of light and high temperature, its color and smell may change.

Biodegradability: steaming ethoxy ether can be degraded by microorganisms in the natural environment, but its degradation rate is slower. Therefore, special attention should be paid to environmental protection.

Applications of Octadecylamine ethoxylate ether  :

Personal Care and cosmetics: In personal Care and cosmetics, ethoxy ether is widely used as an emulsifier, wetting agent and dispersant. It helps to improve the product's stability, wettability, and flexibility, making the product easy to apply and absorb and improving the feeling of use. It is used in cosmetics such as face cream, sunscreen, lipstick, foundation and personal hygiene products such as shampoo and body wash.

Textiles, printing, and dyeing: In the textile industry, ethoxy ether is widely used as a softener, antistatic, and fabric treatment agent. It can improve the feel of the fabric, antistatic properties, and anti-fouling, as well as improve the wearing comfort and durability of the fabric. At the same time, in the printing and dyeing process, steaming ethoxy ether can be used as a dye dispersant, which helps improve the dyeing effect and uniformity.

Pesticides and fertilizers: In producing pesticides and fertilizers, stearine ethoxy ether is widely used as a wetting agent, dispersant and stabilizer. It helps to improve the adhesion and permeability of pesticides, increase the utilization rate, and control the effect of pesticides. At the same time, adding octadecyl ethoxy ether to fertilizer can improve fertilizer's solubility, nutrient utilization rate, and fertilization effect.

Inks and coatings: Stearamine ethoxy ether is widely used as a wetting agent, leveling agent and dispersant in manufacturing inks and coatings. It helps to improve the surface smoothness and uniformity of coatings and improves the appearance and quality of paints and coatings.

Water treatment and sewage treatment: In the fielpaintsewage treatment and water treatment, steaming ethoxy ether is widely used as a dispersant, flocculant and stabilizer. It helps to reduce water's surface tension, improve sludge's flocculation and settling performance, and promote the separation and removal of suspended solids. At the same time, steaming ethoxy ether can also be used to prepare water-based coatings and coatings to improve the construction performance and corrosion resistance of coatings.

Nanomaterial preparation: Steaming ethoxy ether is widely used as a surfactant or template agent in preparing nanoparticles, nanofibers and nanomembranes. It can control the morphology, structure and properties of nanomaterials, improve the dispersion and stability of nanomaterials, and provide important support for the development of nanotechnology.

Production Method of Octadecylamine ethoxylate ether  :

Direct synthesis

The direct synthesis method is the direct reaction of octadecyl amine and ethoxy ether to produce octadecyl amine ethoxy ether. The specific steps are as follows:

The stearamine is mixed with an appropriate amount of ethoxy ether, usually using an equal volume of solvent as a diluent, to regulate the concentration of the reactant.

Under stirring, the mixture is heated to the appropriate reaction temperature, generally between 80 and 150 ° C.

The reaction temperature and stirring rate were kept constant so that the stearamine and ethoxy ether could react completely. During the reaction process, we should pay close attention to the temperature and pressure changes to avoid high and high temperatures.

After the reaction, the reactants were separated and purified by cooling and evaporating solvents to obtain stearine ethoxy ether products.

The advantages of direct synthesis are simple process, low equipment requirements and suitable for large-scale production. However, this method needs to use a lot of ethoxy ether and solvent, which may cause environmental pollution. At the same time, the temperature and pressure need to be controlled during the reaction process, which has high requirements for operation.

Esterification method

The esterification method is to react octadecyl amine with acid to produce octadecyl amine ester and then transesterification with ethoxy ether to produce octadecyl amine ethoxy ether. The specific steps are as follows:

The reaction temperature and stirring rate were kept constant so that the stearamine and the acid completely reacted to produce the corresponding stearamine ester.

The resulting stearine ester was mixed with an appropriate amount of ethoxy ether, and a transesterification reaction was carried out at a suitable temperature and pressure. 

After the reaction, the reactants were separated and purified by cooling and evaporating solvents to obtain stearine ethoxy ether products.

The advantage of esterification is that the waste acid can be recycled by transesterification, and the pollution of the waste acid to the environment can be reduced. At the same time, esterification can improve the product's purity and yield by controlling the transesterification conditions. However, this method needs to use more acid ethoxy ether and other raw materials, which requires higher quality raw materials, making the operation process more complicated.
