Organic Solvent

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.

Formaldehyde is an important organic raw material, which is mainly used in plastic industry (such as phenolic resin, urea formaldehyde plastic electric jade), synthetic fiber (such as synthetic vinylon polyvinyl formal), leather industry, medicine, dyes, etc. Formalin has the ability of sterilization and antisepsis. It can soak biological samples. Its dilute solution (0.1-0.5%) can be used to soak seeds and disinfect seeds in agriculture. Catalytic oxidation is commonly used in industry to produce formaldehyde from methanol. Formaldehyde can react with silver ammonia solution to produce silver mirror, so that a thin layer of metallic silver as bright as a mirror is attached to the inner wall of the test tube (combined silver is reduced and formaldehyde is oxidized); It reacts with the newly prepared copper hydroxide suspension to form red precipitated cuprous oxide.

DMC is a cationic monomer, which can be homopolymerized or copolymerized with other monomers to prepare cationic polymer. The resulting polymer has strong polarity and affinity for anionic substances, so it can be widely used as cationic flocculant. It can be used in sludge dewatering process of sewage treatment plant and wastewater treatment in papermaking, coal flotation, printing, dye and other industries. In addition, DMC can also be used to produce acid resistant super absorbent resin, oilfield chemicals, fiber additives and other fine polymer products.

It is used for the determination of platinum, palladium, mercury and gold, as emulsifier and polymerization inhibitor.

[application 1] it is used as solvent and organic synthesis [application 2] it is a non combustible low boiling solvent. It is used for cellulose acetate film-forming, aerosol, antibiotic and vitamin production. It is also used as extractant and metal cleaning agent [application 3] dichloromethane is the raw material for the production of fungicides myclobutanil and miconazole, and it is also a good solvent. Application 4: extraction solvent. For example, it is used to extract caffeine from coffee beans. It can also be used as extraction solvent for hops, spices and oleoresin. Pigment diluent. [application 5] in addition to organic synthesis, the product is also widely used as cellulose acetate film-forming agent, cellulose triacetate drawing agent, petroleum dewaxing agent, aerosol and solvent in the production of antibiotics, vitamins and steroids, as well as cleaning and degreasing agent for metal surface coatings. In addition, it is also used for grain fumigation and refrigeration of low-pressure refrigerator and air-conditioning device. It is used as auxiliary foaming agent in the production of polyether urethane foam and as a foaming agent for extruding polysulfone foam plastics.
