- Chemical manufacturing uses basic processes, such as: distillation and thermal cracking reactions. The output of these processes is often produced by different chemical elements or by chemical compounds with well-defined distinct chemical properties.
- Industrial gas production
- Production of medical and inorganic industrial gases in liquid or compressed form:
- + Basic gases,
- + Compressed air or liquid,
- + Cooling gas,
- + Mixed industrial gases,
- + Inert gases such as carbon dioxide,
- + Gas isolation.
- Production of dyes and pigments
- Production of dyes and pigments from any source in basic or concentrated form.
- This group also includes:
- Production of products of the same type used as fluorescent brighteners
- Production of other basic inorganic chemicals
- Production of chemical elements;
- + Production of inorganic acids except nitric acid;
- + Production of alkalis, alkaline solutions and other inorganic bases except ammonia;
- + Production of distilled water;
- + Production of other inorganic compounds.
- This group also includes:
- Enriching Uranium and Thorium ores;
- Production of other basic organic chemicals
- + Acrylic hydrocarbon, saturated or unsaturated,
- + Cyclic hydrocarbons, saturated or unsaturated,
- + Acyl alcohol and xylic alcohol,
- + Single or multimolecular carboxylic acids, including acetic acid,
- + Other oxygen-containing compounds include aldehydes, ketones, quino ores and polyfunctional or bifunctional oxygen compounds,
- + Synthetic glycerin,
- + Organic compounds containing nitrogen, including amines,
- + Fermentation of sugars, grains or the like to produce alcohols and esters,
- Other organic compounds.
- Production of other basic chemicals
- Smelting iron sulfide ore;
- Sulfur of all kinds, except sublimed sulfur, precipitated sulfur and colloidal sulfur;
