Chemicals are substances formed by chemical union of two or more elements or ingredients in definite proportion by weight. They are produced by or used in a reaction involving changes in atoms or molecules.
Generally, “chemicals” refers to a much wider class of substances that includes many mixtures of chemical substances that often find application in many vocations.
There are two major types of chemicals:
- Inorganic Chemicals are compounds that do not contain hydrocarbon groups.
- Organic Chemicals are compounds containing hydrocarbon groups.
Chemicals are used to make a wide variety of consumer goods, as well as thousands inputs to agriculture, manufacturing, construction, and service industries.
Acetic acid is a chemical reagent for the production of chemical compounds. The largest single use of acetic acid is in the production of vinyl acetate monomer, closely followed by acetic anhydride and ester production. The volume of acetic acid used in vinegar is comparatively small.
