Chemical industry is "chemical process", "Chemical Industry", "chemical engineering" and so on abbreviation. Any technology that alters the composition, structure, or synthesis of a new substance by chemical means is a chemical production technology, a chemical process, which is called a chemical or chemical product. At first, the production of this kind of products is a handicraft workshop, and later evolved into a factory, and gradually formed a specific production industry is the chemical industry. Chemical Engineering is a science that studies the common law of chemical product production process. The relationship between human and chemical industry is very close, some chemical products in the history of human development, plays an epoch-making important role, their production and application, and even represents a certain historical stage of human civilization.

Early human life depended more on direct use of natural materials. Gradually, the intrinsic properties of these substances can not meet the human needs, resulting in a variety of processing technology, consciously and purposefully to convert natural materials into a variety of properties of new substances, and gradually in the scale of industrial production to be implemented. In a broad sense, where chemical methods are used to change the composition or structure of a substance, or to synthesize a new substance, it is a chemical production technology, a chemical process, which is called a chemical or chemical product.
