Difference between acrylic acid and pure acid

In the chemical industry, although acrylic acid and pure acid are both important chemical substances, there are significant differences in definition, molecular structure, and use. Understanding these distinctions helps to better apply them in their respective fields. The difference between acrylic acid and pure acid will be analyzed in detail from various angles.

1. Definition and Molecular Structure

1. Definition

Acrylic acid is an organic polymer compound with a chemical formula of CH₂ = CHCOOH and a molecular weight of 86.08. It is an acrylate monomer, widely used in coatings, plastics, cosmetics and other fields. Pure acid, on the other hand, usually refers to sulfuric acid (H₂ SOcheck), which has a molecular weight of 98.07 and is a strong acid that is highly corrosive.

2. Molecular structure

The molecular structure of acrylic acid contains a double bond (CH₂ = CH) and a carboxylic acid group (COOH), which makes it chemically stable. The molecular structure of pure acid is only composed of two hydrogen, one sulfur and four oxygen atoms, which is highly acidic and prone to chemical reactions.

2. Physical Properties Comparison

1. Appearance

Acrylic at room temperature is a colorless transparent liquid, density between 1.00 and 1.02. Pure acid is colorless transparent liquid, the color may be slightly yellow due to storage conditions.

2. Conductivity

Acrylic acid is more conductive in solution, but not as high as pure acid. Pure acid as a strong acid, more conductive.

3. USES DIFFERENT

1. Acrylic use

The main uses of acrylic acid include the manufacture of acrylates, coatings, plastics, biodegradable materials, etc. It is widely used in industrial production, especially in the field of biological materials.

2. Pure acid use

The main uses of pure acids include the manufacture of sulfates, battery production, solvent preparation, etc. In the chemical industry, pure acid is a basic raw material.

4. chemical differences

1. Stability

Acrylic acid is relatively stable at room temperature, but may decompose under strong acid or alkali conditions. Pure acid is highly acidic and easily reacts with other substances.

2. Reactivity

Acrylic acid can be polymerized in some cases, while pure acid is more prone to neutralization, acid hydrolysis and other chemical reactions.

5. security and storage methods differ

1. Security

Acrylic acid needs to pay attention to the higher ignition point in the operation, but relatively pure acid, low toxicity. Pure acids are highly corrosive and require special attention to ventilation and operational protection during storage.

2. Storage method

Acrylic acid can be stored in a well-sealed cool place, while pure acid needs to be stored in a cool and ventilated place, away from fire sources and open flames.

6. storage and operation precautions

1. Storage

Acrylic should be stored in a cool, well-ventilated place, away from direct sunlight. Pure acid should also be stored in a cool place, but avoid direct contact with skin and eyes.

To ensure operational safety, it is recommended that storage and handling wear appropriate protective equipment.

From the above analysis, it can be seen that there are significant differences between acrylic acid and pure acid in many aspects. Understanding these differences helps to correctly select and use these two chemicals in practical applications, ensuring the safety and effectiveness of the production process.
