Potassium hydroxide is strongly alkaline and corrosive, and its properties are similar to sodium hydroxide, which can cause burns. It can absorb water and dissolve in the air, and absorb carbon dioxide to gradually become potassium carbonate. The pH of the 0.1 mol/L solution is 13.5.

White oblique crystals, industrial products are white or light gray lumps or rods. Easily soluble in water, emits a lot of heat of dissolution when dissolved, soluble in ethanol, slightly soluble in ether. It is deliquescent and has strong water absorption. Potassium hydroxide is strongly alkaline and corrosive, and its properties are similar to sodium hydroxide, which can cause burns. It can absorb water and dissolve in the air, and absorb carbon dioxide to gradually become potassium carbonate. The pH of the 0.1 mol/L solution is 13.5.

The industrial neighborl xylene is a raw material, first washes the acid layer to the acid layer colorless, then use 10% sodium hydroxide solution, water is washed to pass, and the aqueous layer is separated, and the calcium chloride is borned with anhydrous carbon. After the distinction is low, the intermediate fraction is collected, that is, a pure product.

It is a solvent for a variety of coatings and a raw material for preparing dibutyl phthalate, a plasticizer. It is also used in the manufacture of butyl acrylate, butyl acetate, ethylene glycol butyl ether, as an extractant for organic synthesis intermediates and biochemical drugs, and in the manufacture of surfactants.N-butanol is a colorless, transparent and alcoholic liquid.

It is also used in the manufacture of butyl acrylate, butyl acetate, ethylene glycol butyl ether, as an extractant for organic synthesis intermediates and biochemical drugs, and in the manufacture of surfactants.

Oxygen is a colorless and odorless gas, and the most common elementary form of oxygen. Melting point is -218.4°C, boiling point is -183°C. It is not easily soluble in water, and about 30mL of oxygen can be dissolved in 1L of water. Oxygen in the air accounts for about 21%. Liquid oxygen is sky blue. Solid oxygen is blue crystals.

Appearance: watery bright liquid with pleasant ketone-like fragrance. Main uses: Used as a solvent for spray paint, nitrocellulose, some fiber ethers, camphor, grease, natural and synthetic rubber. Precautions for storage and transportation: Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. The warehouse temperature should not exceed 30℃. Avoid direct sunlight. Keep the container sealed. It should be stored separately from oxidant. Lighting, ventilation and other equipment in the storage room should be explosion-proof.

HCFC-141b (monofluorodichloroethane) is a high-purity liquid widely used in cleaning and solvent fields. Because its damage to the ozone layer is 1/10 of CFC-113, it is designated as an ideal substitute for fully halogenated chlorofluorocarbons. HCFC-141b is a widely used non-perhalogenated chlorofluorocarbon. Although its destructive effect on the ozone layer has been greatly reduced compared to fully halogenated chlorofluorocarbons, it can still cause damage to the ozone layer that is difficult to recover. As a result, its use is gradually being reduced around the world.

Sulfur, white and shiny crystal compounds. The taste is bitter, density is 1.405, and the melting point is 180 to 182 ° C. Decomposition when it is hotter, soluble in water, can be dissolved in ethanol when heating, and is slightly dissolved in ether. During the melting, heterogeneity is partialized to form ammonium thiocyanomylisocyanomylocyne. The raw materials used to make drugs, dyes, resins, and plastic powder, and are also used as a vulcanized promoter for rubber, flotal agents for metal minerals.
