Role in skin care products:

Pyrrolidone carboxylic acids are mainly used in skin care products to moisturize, but also act as skin conditioners and antistatic agents.

Pyrrolidone carboxylic acids attract moisture and keep skin and hair moist, soft, elastic, and shiny. Pyrrolidone carboxylic acid also has a skin-lightening effect due to its ability to inhibit the activity of tyrosine oxidase, thereby preventing the deposition of melanin. In addition, it has a softening effect on the corneas and helps to improve skin problems such as psoriasis. Pyrrolidone carboxylic acid is suitable for a variety of skin care products, such as creams, shampoos, conditioners, toothpaste, etc. It is usually found in the form of sodium salt because it is more soluble and mild to the skin, which does not cause allergy or irritation.

Analysis of pyrrolidone process

I. Summary

Pyrrolidone is an important organic compound widely used in pharmaceutical, pesticide and dye fields. This paper will introduce the specific steps of the pyrrolidone process.

Ii. Preparation of raw materials

The production of pyrrolidone requires benzoic acid and pyrrolidine-dione as raw materials. The quality of these two raw materials is critical to the quality of the final product and therefore requires careful screening and quality control. Benzoic acid can be obtained from industrial grade products purchased by chemical plants, while pyrrolidinone is obtained by synthetic reaction.

Third, reaction conditions

The synthesis of pyrrolidinone is generally performed using a hot acid catalyst with a reaction temperature of 150-200 ° C and a reaction time of 6-10 hours. In this reaction, benzoic acid undergoes condensation reaction with pyrrolidinone to form pyrrolidinone. Pyrrolidone can be obtained by cooling, separating and washing the reaction products.

Iv. Product purification

The resulting pyrrolidone needs to be purified to improve product purity and quality. The purification process includes crystallization, recrystalization, solvent extraction, column chromatography and other steps, and the specific method can be selected according to different actual situations.

Five, advantages and disadvantages and application prospects

As an important organic compound, the production process of pyrrolidone has the following advantages:

1. Mild reaction conditions, short reaction time, can reduce production costs and investment risks.

2. The process is simple and easy to carry out large-scale production.

3. The product has high purity and stable quality, which can meet the needs of different fields and customers.

However, the production process of pyrrolidone also has some disadvantages, such as:

1. The number of catalysts is large and the recovery of catalysts is difficult.

2. Large amount of reaction wastewater is produced, and wastewater treatment and discharge are required.

Considering the above advantages and disadvantages, pyrrolidone production technology has a certain application prospect, and can be widely used in medicine, pesticides, dyes, spices and other fields.

Chemical properties:

Colorless crystals. The melting point was 24.6℃, the boiling point was 245℃, the relative density was 1.116 (25/4℃), the refractive index was 1.4870. Can be miscible with water, alcohol, ether, chloroform, benzene, ethyl acetate and carbon disulfide, insoluble in petroleum ether.

Application:

2-pyrrolidone can be used as solvent and organic synthesis intermediate, used to make nylon -4 and vinyl pyrrolidone, etc. It can also be used as a solvent for synthetic resins, pesticides, polyols, oil Chemicalbook ink, iodine, etc. It can also be used as plasticizer of acrylic acid and styrene resin, extractant of aromatic compounds, decolorizing agent of kerosene, rosin, fatty acid, etc.
