Ethanol is an important organic solvent, which is widely used in medicine, coatings, sanitary products, cosmetics, grease and other methods, accounting for about 50% of the total consumption of ethanol. Ethanol is an important basic chemical raw material, which is used to manufacture acetaldehyde, ethylene diene, ethylamine, ethyl acetate, acetic acid, chloroethane, etc., and derived many intermediates of medicine, dyes, coatings, spices, synthetic rubber, detergent, pesticides and other products. There are more than 300 kinds of products, but at present, the use of ethanol as an intermediate of chemical products is gradually declining, Many products, such as acetaldehyde, acetic acid and ethyl ethanol, no longer use ethanol as raw materials, but use other raw materials instead. 75% ethanol aqueous solution has strong bactericidal ability and is a common disinfectant. Specially refined ethanol can also be used to make beverages. Similar to methanol, ethanol can be used as energy. Some countries have begun to use ethanol alone as vehicle fuel or mixed with gasoline (more than 10%) to save gasoline.

Anhydrous citric acid is a kind of intermediate product of natural components and physiological metabolism in animals and plants, and also one of the most widely used organic acids in food, medicine, chemical industry and other fields. It is colorless, transparent or translucent crystal, or granular, particle like powder, odorless, although it has strong acid taste, but pleasant, slightly astringent. It is gradually weathered in warm air, and slightly deliquescence in humid air. Anhydrous citric acid is known as the first edible acid agent, and it is widely used in food industry as acid agent, solvent increasing, buffer, antioxidant, deodorizer and chelating agent. In the field of medicine, effervescent is a popular oral drug ingredient release system. Citric acid reacts with sodium carbonate or sodium bicarbonate aqueous solution to produce a large amount of CO2 (i.e. effervescent) and sodium citrate, which can make active ingredients in the drug dissolve rapidly and enhance taste ability. In industry, the citric acid based metal purification formula can effectively remove oxides formed on the surface of ferrous and non-ferrous metals. As a weak organic acid, it can cause slight damage to the metal surface layer. However, as a metal ion chelator, the migration of gold oxide is accelerated, in many steel leaching systems, In order to eliminate the stress crack of metal oxide and reduce the brittleness of high strength steel to the lowest degree, citric acid was used to remove rust instead of inorganic strong acid.

Mineral oil refers to the base oil extracted from petroleum using physical distillation method called mineral oil, white mineral oil, usually refers to white mineral oil. It is a special deep-refined mineral oil, so white mineral oil is colorless, tasteless, chemically inert, and has good light stability. Its basic composition is a saturated hydrocarbon structure, and aromatic hydrocarbons, nitrogen, oxygen, sulfur and other substances are close to zero. Has good oxidation stability and chemical stability.

Oleic acid is an unsaturated fatty acid with a carbon carbon double bond in its molecular structure. It is a fatty acid that constitutes olein. One of the most extensive natural unsaturated fatty acids, which has a certain effect on softening blood vessels and plays an important role in the metabolism of human and animals. However, the oleic acid synthesized by human body can not meet the needs and should be taken from food. Therefore, eating edible oil with high oleic acid content is beneficial to health. Oleic acid can also be used to make soap, lubricant, flotation agent, ointment and oleate. It is also a good solvent for fatty acids and oil soluble substances.

Sodium dodecyl sulfate is a kind of anionic surfactant, which belongs to the typical representative of sulfate surfactant. The products sold on the market are usually white to yellowish crystalline powder, non-toxic, slightly soluble in alcohol, insoluble in chloroform and ether, and easily soluble in water. It has good compatibility with anionic and non-ionic surfactants, and has good emulsification, foaming, foaming, permeability, etc However, its water solubility is lower than that of fatty alcohol polyoxyethylene ether sodium sulfate.
