The properties and uses of liquid paraffin are of great significance in the field of raw materials for chemical production. In this paper, the properties, production methods, uses and safety assessment of liquid paraffin will be discussed in detail to show its important position in the field of chemical production raw materials.

1. the nature of liquid paraffin

Liquid paraffin is a colorless, transparent, tasteless, odorless oily liquid, mainly composed of hydrocarbons. Its chemical properties are stable, not easy to react with other substances, with good heat resistance, cold resistance and oxidation resistance. Liquid paraffin has low viscosity, good fluidity, and is easy to transport and store. In addition, it also has low toxicity, low volatility and good electrical insulation.

2. liquid paraffin production method

liquid paraffin production method mainly has two kinds: one is the petroleum fractionation method, through the petroleum refining process of the fractionation step, obtain a certain number of carbon atoms of hydrocarbon mixture; The other is the synthesis method, through the chemical synthesis method to obtain a specific number of carbon atoms of hydrocarbon compounds. In actual production, the appropriate production method can be selected according to the source of raw materials and product requirements.

3. the use of liquid paraffin

1. chemical raw materials: liquid paraffin can be used as raw materials for many chemicals, such as the production of detergents, lubricants, solvents and so on.
2. Plastic additives: Liquid paraffin can be used as an additive in the plastic processing process, which can play the role of plasticization and lubrication, and improve the processing performance and use performance of plastics.
3. Textile industry: Liquid paraffin can be used in the textile industry as a lubricant and a treatment agent to improve the waterproof performance of textiles.
4. pharmaceutical industry: in the pharmaceutical industry, liquid paraffin can be used as a light release agent for the treatment of constipation and other symptoms.
5. Food industry: Liquid paraffin can be used in the food industry as a food additive to prevent sticking and demolding. Safety evaluation

of

4. liquid paraffin Although liquid paraffin is widely used in various fields, it still needs to pay attention to safety in the process of production and use. Liquid paraffin is a low-toxic substance, but it may cause adverse effects on the human body in the case of large-scale contact or accidental ingestion. Therefore, it is necessary to strictly abide by the relevant safety regulations during operation to ensure the health and safety of the staff.

In short, liquid paraffin, as an important raw material for chemical production, is widely used in various fields. Understanding and mastering its nature, production methods, uses and safety assessment is of great significance to improve the production efficiency and product quality of chemical products. In the actual production process, the appropriate production method should be selected according to specific needs and conditions to ensure the quality and safety of liquid paraffin. At the same time, strengthen the safety management in the production process, reduce potential risks, and ensure the smooth progress of production.
