Research on
the Properties and Uses of Petroleum Naphthalene
Abstract

This paper discusses in detail the properties and uses of petroleum naphthalene in the field of raw materials for chemical production. The important position of petroleum naphthalene in the production of chemical products was revealed through the in-depth study of the physical properties, chemical properties, toxicity, safety and production methods of petroleum naphthalene. At the same time, this paper also discusses the wide application of petroleum naphthalene in various fields, including as a solvent, the production of resins and rubbers, the preparation of dyes and drugs.

1. the nature of petroleum naphthalene

1. physical properties
petroleum naphthalene is a colorless or slightly yellow crystalline solid, with a special smell. It has a higher melting point and a lower boiling point. Petroleum naphthalene is insoluble in water, but soluble in a variety of organic solvents.
2. chemical properties of
petroleum naphthalene has high chemical stability, not easy to occur oxidation, reduction and other reactions. However, in the presence of high temperature and catalyst, petroleum naphthalene can be hydrogenated, dehydrogenated, alkylated and other reactions. In addition, petroleum naphthalene can also react with acid, alkali and other substances.
3.
of toxicity Petroleum naphthalene has certain toxicity to human and animals. Long-term exposure to petroleum naphthalene may cause health problems such as nervous system damage, liver and kidney dysfunction. Therefore, it is necessary to strictly abide by the safety operation procedures in the production and use process.

2. petroleum naphthalene uses

1. used as a solvent
petroleum naphthalene is an excellent solvent, can be used to extract vegetable oil, resin, rubber and other substances. At the same time, petroleum naphthalene can also be used as a thinner for paints, coatings and other products.
2. Production of resin and rubber
Petroleum naphthalene can be used as raw materials for the production of a variety of resin and rubber products, such as phenolic resin, styrene resin, styrene butadiene rubber, etc. These products are widely used in construction, automobile, aviation and other fields.
3. Preparation of Dyes and Pharmaceutical
Petroleum naphthalene can be used to prepare a variety of dyes and pharmaceuticals. For example, certain derivatives are useful as anticancer drugs, antimalarial drugs, and the like. In addition, petroleum naphthalene can also be used in the production of food additives, spices and so on.

3. Petroleum Naphthalene Production Process

Petroleum Naphthalene is mainly obtained by distillation of petroleum or coal tar. In the distillation process, compounds with different boiling points are separated in turn, including petroleum naphthalene. In order to obtain petroleum naphthalene with higher purity, further refining operation is required.

4. safety considerations

in the production and use of petroleum naphthalene, need to strictly abide by the safety procedures to prevent the occurrence of fire, explosion and other safety accidents. At the same time, workers need to wear protective equipment to avoid direct contact with petroleum naphthalene to reduce the impact on health.

conclusion

petroleum naphthalene as an important raw material for chemical production has a wide range of applications in many fields. Through the in-depth study of the properties and uses of petroleum naphthalene, it is helpful to better understand and utilize this resource and provide support for the development of the chemical industry. At the same time, it is necessary to strengthen safety management in the process of production and use to ensure the health and safety of staff and the public.
