What harm does acetone do to the human body

Acetone is a chemical product generally used in industry. Acetone has a relatively high risk factor. If you accidentally take it, it will cause dry mouth and vomiting. In severe cases, it may cause impaired consciousness. Many people think that as long as they are careful not to ingest it, it is not the case. If you inhale too much, it may cause dizziness and nausea, and in severe cases it may even lead to coma. This article introduces the detailed content, let’s take a look.

1. Hazards of acetone

1. Oral administration: After oral administration, there will be a burning sensation on the lips and throat. After a latent period of several hours, dry mouth, vomiting, drowsiness, acidosis and ketosis, and even temporary impaired consciousness may occur. The long-term damage of acetone to the human body manifests itself as eye irritation symptoms such as tearing, photophobia and corneal epithelial infiltration, as well as dizziness, burning sensation, throat irritation, coughing, etc.

2. Inhalation: Concentrations below 500 ppm have no effect. Concentrations between 500 and 1000 ppm will irritate the nose and throat. Concentrations of 1000 ppm may cause headaches and dizziness. 2000-10000 ppm can cause dizziness, drunkenness, drowsiness, nausea and vomiting, and high concentrations can lead to loss of consciousness, coma and death.

3. Eye contact: Concentration of 500ppm will cause irritation, and 1000ppm will cause mild, temporary irritation. Liquids can be toxic and irritating.

4. Skin irritation: The liquid may cause mild irritation, but the risk of absorption through intact skin is very small.

5. Skin contact can cause dryness, redness, swelling and cracking. Inhaling 1000ppm vapor for 3 hours a day will irritate the workers' nasal cavity, causing dizziness and fatigue in 7 to 15 years. High concentrations of vapor can affect kidney and liver function.

2. Industrial production of acetone

1. Obtain calcium acetate from acetic acid, and then heat it to 160 degrees Celsius to decompose it into acetone and calcium carbonate;

2. Acetylene reacts with water vapor over a zinc oxide catalyst to produce acetone;

3. Ethanol vapor reacts at high temperature in the presence of zinc chromate catalyst to produce acetone;

4. Oxidation of liquefied natural gas or naphtha to produce acetone (oxidation products also include formaldehyde, acetic acid, butanol, etc.);

5. Oxidation or dehydrogenation of isopropanol to produce acetone;

6. Acetone produced by isopropyl alcohol hydrogen peroxide method;

7. Acetone is synthesized from isopropyl alcohol and acrolein.
