Tert butanol

2-methyl-2-propanol is an organic compound with the chemical formula C4H10O.

propionic acid

Propionic acid, also known as primary oleic acid, is a short chain saturated fatty acid with the chemical formula CH3CH2COOH and a molecular weight of 74.08. Propionic acid belongs to weak electrolytes (Ka=1.34 × 10-5), and its aqueous solution is weakly acidic but highly corrosive. Steam is irritating to the skin and respiratory tract. At room temperature and pressure, propionic acid is a colorless, clear, oily liquid with an unpleasant odor of rancidity. It is miscible with water, ethanol, chloroform, and ether.

Dimethyl sulfoxide

Dimethyl sulfoxide

Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound that is a colorless, odorless, and transparent liquid at room temperature. It is a hygroscopic and flammable liquid. It has the characteristics of high polarity, high boiling point, good thermal stability, non proton, and water solubility. It can dissolve in most organic compounds such as ethanol, propanol, benzene, and chloroform, and is known as the "universal solvent". Heating in the presence of acid will produce small amounts of compounds such as methyl mercaptan, formaldehyde, dimethyl sulfide, and methanesulfonic acid. It decomposes at high temperatures and reacts violently with chlorine, emitting a light blue flame when burned in air. Can be used as organic solvents, reaction media, and organic synthesis intermediates. It can also be used as a dyeing solvent, dye remover, dyeing carrier for synthetic fibers, as well as an absorbent for recovering acetylene and sulfur dioxide.

Formaldehyde

Colorless or yellow crystals or liquids with deliquescence. Dissolve in ethanol, ether, and water. It is chemically active and can undergo addition or condensation reactions with ammonia, amides, aldehydes, and compounds containing carboxyl groups. Mainly used in the textile industry. Produced by gas-phase catalytic oxidation of ethylene glycol and air.

styrene

Styrene (C8H8) is an organic compound formed by replacing one hydrogen atom of ethylene with benzene. The electron of the vinyl group is conjugated with the benzene ring and is insoluble in water. It is soluble in ethanol and ether and gradually undergoes polymerization and oxidation when exposed to air. In industry, it is an important monomer for synthetic resins, ion exchange resins, and synthetic rubber.

hydrochloric acid

hydrochloric acid

Hydrochloric acid is an aqueous solution of hydrogen chloride (HCl), which is a strong inorganic acid with a wide range of industrial applications. Hydrochloric acid is a colorless and transparent liquid with a strong pungent odor and high corrosiveness. Concentrated hydrochloric acid (with a mass fraction of about 37%) has extremely strong volatility, so when the container containing concentrated hydrochloric acid is opened, the hydrogen chloride gas will evaporate and combine with water vapor in the air to produce small droplets of hydrochloric acid, causing acid mist to appear above the bottle mouth. Hydrochloric acid is the main component of stomach acid, which can promote food digestion and resist microbial infections.

nitric acid

Nitric acid is a strong acid with strong oxidizing and corrosive properties, belonging to the category of inorganic strong acids. It is one of the six major inorganic strong acids and an important chemical raw material. It can be used in industry to produce fertilizers, pesticides, explosives, dyes, salts, etc; In organic chemistry, a mixture of concentrated nitric acid and concentrated sulfuric acid is an important nitration reagent, and its aqueous solution is commonly known as nitrate solution or ammonia nitrogen solution. The hazard symbols are O (oxidizing agent) and C (corrosive).

sulphuric acid

Sulfuric acid is a lively binary inorganic strong acid that can react with the vast majority of metals. High concentration sulfuric acid has strong water absorption and can be used as a dehydrating agent to carbonize carbohydrate containing substances such as wood, paper, cotton and linen fabrics, and biological skin. When mixed with water, a large amount of heat energy is also released. It has strong corrosiveness and oxidizing properties, so it should be used with caution. It is an important industrial raw material that can be used to manufacture fertilizers, drugs, explosives, pigments, detergents, batteries, etc. It is also widely used in industries such as petroleum purification, metal smelting, and dyes. Commonly used as a chemical reagent, it can be used as a dehydrating agent and sulfonating agent in organic synthesis.

Sodium hydroxide (caustic soda)

Sodium hydroxide (caustic soda)

Commonly known as caustic soda, caustic soda, or caustic soda, it is a highly corrosive strong alkali that is generally in the form of flakes or particles. It is easily soluble in water (releases heat when dissolved in water) and forms an alkaline solution. It also has deliquescence and can easily absorb water vapor and carbon dioxide from the air. NaOH is one of the essential chemicals in chemical laboratories and is also a common chemical product.
