Liquid ammonia

Liquid ammonia is a colorless liquid with a strong pungent smell. As an important chemical raw material, ammonia is usually compressed or cooled to obtain liquid ammonia for the convenience of transportation and storage.

Methanol

Methanol, also known as hydroxymethane, is an organic compound and the simplest saturated monohydric alcohol. Its chemical formula is CH3OH/CH4O, in which CH3OH is a simple formula, which can extrude the hydroxyl of methanol. CAS No. is 67-56-1, molecular weight is 32.04, and boiling point is 64.7 ℃. It is also called "xylitol" or "lignin" because it is first found in dry distillation wood. The lowest dose of poisoning for the population is about 100mg/kg body weight, and 0.3~1g/kg oral intake can cause death. It is used in the manufacture of formaldehyde and pesticides, as well as as the extractant of organic matter and denaturant of alcohol.

Ethanol

Ethanol is a volatile colorless transparent liquid under normal temperature and pressure, with low toxicity. Pure liquid cannot be directly drunk. The aqueous solution of ethanol has the smell of wine, slightly irritating and sweet. Ethanol is flammable, and its vapor can form an explosive mixture with air.

Dichloromethane

Dichloromethane, an organic compound, is a colorless transparent liquid with an irritating odor similar to ether. Slightly soluble in water, soluble in ethanol and ether, it is a nonflammable low boiling point solvent under normal conditions of use. When its vapor becomes high concentration in high temperature air, it will generate weakly combustible mixed gas, which is often used to replace flammable petroleum ether, ether, etc.

Dichloroethane

Dichloroethane (formula: 98.97), namely o-dichloroethane, is a kind of halogenated hydrocarbon, which is usually expressed by EDC. Colorless or light yellow transparent liquid melting point - 35.7 ℃, boiling point 83.5 ℃, density 1.235g/cm ³， Flash point 17 ℃. Insoluble in water is mainly used as an intermediate in the preparation of vinyl chloride (PVC monomer), as well as as a solvent. It is a colorless liquid with chloroform like odor at room temperature, toxic and potentially carcinogenic. Possible solvent alternatives include 1,3-dioxocyclohexane and toluene. Used as solvent and intermediate of trichloroethane. It is used as solvent for wax, fat, rubber, etc. and as grain insecticide.

Cyclohexanone

Cyclohexanone, an organic compound, is a saturated cyclic ketone with carbonyl carbon atoms included in the six membered ring. Colorless transparent liquid with earthy smell. When it contains trace amount of phenol, it has mint smell. The impure substance is light yellow, which is colored by impurities generated with storage time, and is white to grayish yellow, with a strong pungent odor. The explosive pole mixed with air is the same as the open chain saturated ketone. In industry, it is mainly used as organic synthesis raw material and solvent, for example, it can dissolve nitrocellulose, paint, paint, etc.
