An article to read fatty alcohol polyoxyethylene ether sodium sulfate (AES) Structure of 1. AES AES is the abbreviation of the anionic surfactant fatty alcohol polyoxyethylene ether sodium sulfate. It is a modified product of non-ionic surfactant fatty alcohol polyoxyethylene ether (AEO) which is sulfated by sulfating agent and then neutralized by alkaline neutralizing agent. Its molecular structure has oxyethylene groups and sulfated groups, and has the properties of nonionic and anionic surfactants. Has a strong wetting, dispersing, emulsifying and detergency; has a very good resistance to hard water and biodegradability; foaming power is rich, and the skin irritation is small, the use of mild, transparent and stable solution.

Natural high fatty alcohols are the basic raw materials for fine chemical products such as detergents, surfactants, plastic plasticization, etc. There are thousands of fine chemical products produced by them, which are widely used in chemical, petroleum, metallurgy, textile, machinery, Mining, construction, plastics, rubber, leather, papermaking, transportation, food, medicine and health, daily chemical industry and agriculture. Fatty alcohols can produce many derivatives. Alcohol series surfactants are the fastest growing products among all kinds of surfactants since the 1980 s. As a detergent active substance, it has excellent properties such as strong decontamination ability, good compatibility, low foam, easy biodegradation, hard water resistance and good washing performance in low temperature water. It has gradually replaced linear alkyl benzene sulfonate (LAS) and dodecyl benzene sulfonic acid, and has become the third generation detergent raw material. The most representative varieties here are AEO3 ~ 9 synthesized by fatty alcohol and ethylene oxide, etc., which can also be sulfonated to form AES. These alcohol-based surfactants have wide applications and large demand, and are closely related to the improvement of daily life and quality of life. The actual market and potential market are broad. Therefore, they provide a broader world for the production of fatty alcohols, especially natural lipoimetics. Plastic additives are auxiliary raw materials for the plastics industry, and the additives industry develops with the development of the plastics industry. The rapid development of China's plastics industry is well known. In 1985, the world consumed 13 million tons of various plastic auxiliaries, and plasticizer is one of the largest amount of plastic auxiliaries. At present, the production capacity of foreign plasticizer has exceeded 4.5 million tons, while that of China has exceeded 500000 tons. Among the plasticizers, the production of dibutyl phthalate (DBP) and dioctyl phthalate (DOP), in addition to phthalic anhydride raw materials, butanol and octanol are also the main raw materials. At present, China consumes more than 300000 tons of butanol and octanol each year to produce these two plasticizers. However, butanol and octanol have short carbon chains. The plasticizers produced by them are far from meeting the development needs of plastic processing industry in terms of heat resistance, weather resistance and electrical insulation. At present, high carbon chain aliphatic alcohols, such as C10, C12, C14, C16, C18 and other alcohols, are being tried to replace butanol and octanol to produce plastic products with excellent heat resistance, weather resistance and electrical insulation properties, promote the expansion of plastic use. Therefore, the application of high carbon fatty alcohols in the plastic plasticizer industry is also quite promising. The application of natural fatty alcohol in daily chemical industry has better advantages than chemical synthetic alcohol. Compared with the two, even if various physical and chemical quality indicators are the same, people still prefer to use natural alcohol, which has become a popular "green" trend. Therefore, natural fatty alcohols are ideal raw materials in the cosmetics industry, such as liquid and ointment soap, toothpaste, cosmetic cream, etc.

1. High pressure hydrogenation method Fatty alcohols are obtained from animal and vegetable oils and fats by high-pressure hydrogenation. In industry, raw oils and fats are converted into fatty acids by pretreatment, alcoholysis (I. e., transesterification) and then hydrogenated. Fatty acids can also be hydrogenated directly or esterified to form alcohols. Direct hydrogenation of fatty acids to fatty alcohols requires high equipment materials. Fatty acid hydrogenation of fatty alcohol chemical reaction: RCOOH 2H2-→RCH2OH H2O Fatty acid ester hydrogenation of fatty alcohol chemical reaction: RCOOR′ 2H2-→RCH2OH R′OH High pressure hydrogenation method has fixed

Fatty alcohol was first made from cetacean, and the resulting mixed fatty alcohol was sulfonated and neutralized into sulfate, which is the earliest anionic detergent. Subsequently, coconut oil, palm oil and butter, which are abundant in sources, were developed and utilized as raw materials. The fatty acids resulting from the hydrolysis are again reduced to alcohols. Collectively referred to as natural fatty alcohols. After the development of the petrochemical industry, the production of fatty alcohols from petroleum products is called synthetic fatty alcohols. The more important methods for the production of fatty alcohols are high-pressure hydrogenation, Ziegler and oxo synthesis. If the hair mask contains unsaturated fatty alcohol, it can repair and nourish hair; the addition of fatty alcohol to lip gloss can enhance the smoothness of the product when used.
