Cotton has a high burning rate. But that can be fixed by applying flame retardant chemicals. It does not only provide the raw materials for the plastics and other synthetics that are everywhere, but also the fuel for energy, industry, heating, and transportation. From a chemical point of view, petroleum is an extremely complex mixture of hydrocarbon compounds, usually with small amounts of impurities- nitrogen, oxygen, sulfur and small amounts of trace metals. Petroleum products are the basic materials used for the manufacturing of synthetic fibers for clothing and in plastics, insecticides, synthetic rubber, fertilizers, and soap.
Distillation is the primary method used to separate.
Petroleum products are used to make petrochemicals, which are the most expensive of all petroleum manufacturers. In petrochemical production, oil distillation products are broken down by cracking them into light, and unsaturated gases, which are then recombined in many ways to slow down intermediate products, such as styrene, butadiene, ethanol, methanol, chloride, and ethyl. These intermediates are used for the manufacturing of plastics, synthetic fibers, products, and synthetic rubbers. Starch Starch is made by green plants through photosynthesis to serve as a metabolic reserve. Therefore, it is classified as a nutrient polysaccharide, different to similar carbohydrate structures that are used for support.
