In the process of chemical production, raw materials are essential components. However, not all chemicals require self-production of raw materials. So, why do some chemicals need to produce their own raw materials while others do not? This article will provide a detailed explanation.

For large-scale chemical enterprises, they have their own raw material production bases where they can carry out large-scale production and processing. These enterprises typically choose to obtain the required raw materials from their own production bases, which is then processed and used in the production of chemicals. This approach not only ensures the quality and supply of raw materials but also reduces costs and risks. For example, BASF, a chemical enterprise with chemical production as its main business, has several factories in Germany that have their own raw material production bases, which can ensure stable supply and quality of raw materials.

For small-scale chemical enterprises and special chemicals, they may not have their own raw material production bases. In this case, they need to obtain the required raw materials through purchasing or recycling. These raw materials may come from other companies or institutions and must undergo certain processing and inspection before being used in chemical production. To ensure the quality and safety of raw materials, these enterprises usually choose to purchase raw materials from reputable suppliers and conduct strict testing and assessment. For example, some pharmaceutical companies need to purchase various drug raw materials from professional pharmaceutical raw material suppliers and conduct rigorous quality control and testing.

In addition, for some special chemicals, they may need to use rare metals or special organic materials that are difficult to obtain. In this case, these enterprises need to cooperate with other companies or institutions to obtain the necessary raw materials. For example, some high-tech companies may collaborate with research institutes to develop new materials, jointly utilizing rare metal resources and so on.

Finally, for some chemicals, they can obtain the required raw materials by biological fermentation. For example, some food additives and medical intermediates can be produced through microbial fermentation, which not only reduces production costs but also reduces environmental pollution.

In summary, not all chemicals require self-production of raw materials. For large-scale chemical enterprises and those with their own raw material production bases, they typically choose to obtain raw materials from their own production bases. For small-scale chemical enterprises and special chemicals, they need to purchase or recycle raw materials through reputable suppliers after undergoing certain processing and inspection. The key is to ensure the quality and safety of raw materials while reducing costs and environmental impact.
