I. Introduction

Chemical industry, that is, the chemical industry that changes the composition or structure of substances or synthesizes new substances by chemical methods, belongs to chemical production technology, that is, chemical process, and the products obtained are called chemicals or chemical products.

In modern life, chemical products are indispensable almost anytime and anywhere. From material life such as food, clothing, housing and transportation to spiritual life such as culture, art and entertainment, chemical products are needed to serve them.

Some chemical products play an epoch-making and important role in the history of human development. Their production and application even represent a certain historical stage of human civilization.

Second, the technical terms

Chemical industry, chemical engineering and chemical technology are all called chemical industry for short. The chemical industry includes oil chemicals, chemical metallurgy, pharmaceuticals, polymers, paints, oils and fats, etc. They appear in different historical periods, each with different meanings, but they are closely related, infiltrated and continuous, and have been given new contents in their development process. The early life of human beings depends more on the direct use of natural materials. Gradually, the inherent properties of these substances can no longer meet the needs of human beings, so various processing technologies have emerged, consciously and purposefully transforming natural substances into new substances with various properties, and gradually putting them into practice on the scale of industrial production. Broadly speaking, any chemical method to change the composition or structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical process, and the products obtained are called chemicals or chemical products.
