Acetone CAS67-64-1

Acetone, also known as dimethyl ketone, is an organic compound with the formula C3H6O, the simplest saturated ketone. At room temperature and pressure, it is a colorless flammable liquid with a mint odor [2]. Soluble in water and methanol, ethanol, ether, chloroform, pyridine and other organic solvents. Flammable, volatile, chemical properties are more active. In the industry, it is mainly used as a solvent for explosives, plastics, rubber, fiber, leather, grease, spray painting and other industries, and can also be used as an important raw material for the synthesis of ketene, acetic anhydride, iodoform, polyisoprene rubber, methyl methacrylate, chloroform, epoxy resin and other substances, and is often used as a raw material of bromophenylacetone by illegal elements.

use

1. Acetone is a representative polar solvent with low boiling point and fast drying. Strong dissolving ability, but also soluble in water, in addition to being used as paint, varnish, nitro spray paint and other solvents, is also used as cellulose, cellulose acetate, photographic film and other manufacturing solvents and paint remover. Acetone can extract various vitamins and hormones and dewaxing petroleum. Acetone is also an important chemical raw material, used in the manufacture of acetic anhydride, methyl methacrylate, bisphenol A, isopropylidene acetone, methyl isobutyl ketone, hexadiol, chloroform, iodoform, epoxy resin, vitamin C, etc. And used as extractant, diluent and so on.

2. It is used to prepare organic chemical raw materials such as plexiglass monomer, bisphenol A, diacetone alcohol, hexanediol, methyl isobutyl ketone, methyl isobutyl methanol, voorone, isoorone, chloroform and iodoform. It is used as an excellent solvent in coating, acetate fiber spinning process, cylinder storage of acetylene, oil refining industry dewaxing, etc. In the pharmaceutical industry, it is one of the raw materials of vitamin C and the anesthetic Soprana, and is also used as an extractant in the production of various vitamins and hormones. In the pesticide industry, acetone is one of the raw materials for the synthesis of propylene pyrethroids.

3. Used as an analytical reagent, such as a solvent. Used as chromatographic derivative reagent and liquid chromatography eluent.

4. Used in electronics industry, commonly used as cleaning agent.

5. Commonly used as a solvent for vinyl resin, acrylic resin, alkyd paint, cellulose acetate and a variety of adhesives. It is also widely used in the manufacture of cellulose acetate, film, film and plastics, and is also A raw material for the production of methyl methacrylate, methyl isobutyl ketone, bisphenol A, acetic anhydride, ketene and furan resin.

6. It can be used as diluent, detergent and extractant of vitamins and hormones.

7. Natural acetone also exists in nature, and the human body also contains a small amount of acetone. In building materials, it is mainly used as the main raw material of aliphatic water reducer.

Transportation and storage

Mode of transport

Transport vehicles should be equipped with the appropriate variety and quantity of fire equipment and leakage emergency treatment equipment. It is best to transport early and early in summer. The tank (tank) car used in transportation should have a grounding chain, and a hole partition can be provided in the tank to reduce static electricity generated by shock. It is strictly prohibited to mix with oxidants, reducing agents, alkalis, edible chemicals, etc. During transportation, it should be protected from sunlight, rain and high temperature. Stay away from fire, heat source and high temperature area during stopover. The exhaust pipe of the vehicle carrying the article must be equipped with a fire retardant device, and the loading and unloading of mechanical equipment and tools that are easy to produce sparks is prohibited. Road transport should follow the prescribed route, do not stay in residential areas and densely populated areas. It is forbidden to slip them in railway transportation. It is strictly prohibited to use wooden or cement ships for bulk transport.

Storage method

1. This product is highly inflammable and has serious fire danger, belonging to Class A fire danger substance. Store in a cool, dry and well-ventilated place, away from heat source, fire source and prohibited substances. All containers should be placed on the ground. However, the stored and recovered acetone often has acidic impurities and is corrosive to metals.

2, with 200 L iron drum packaging, net weight of 160 kg per barrel, iron drum inside should be clean and dry. Store in a dry, ventilated place, the temperature is kept below 35 ℃, loading and unloading, transportation to prevent violent impact, and prevent the sun and rain. It shall be stored and transported in accordance with the provisions on fire and explosion-proof chemicals.

3, stored in a cool, well-ventilated warehouse room, away from fire, heat sources. The storage temperature should not exceed 29 ℃. Keep the container sealed. It should be stored separately from oxidants, reducing agents and alkalis, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. The storage area should be equipped with leak emergency treatment equipment and suitable containment materials.
