Laboratory chemicals refer to any chemical that's used in laboratory testing and experiments. Most are standard chemical reagents or simple chemicals that serve as basic ingredients to synthesise more complex chemicals.
alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel.
There are four types of industry, namely primary, secondary, tertiary and quaternary.
Traditionally, chemistry has been broken into five main subdisciplines: Organic, Analytical, Physical, Inorganic and Biochemistry.
The types are: 1. Inorganic and Organic Chemical Industries 2. Fertilizer Industries 3. Refineries and Petroleum Industry 4.
Most production of basic chemicals is concentrated along the Gulf Coast, where petroleum and natural gas feedstocks are available in refineries. Texas and Louisiana produce a majority of all primary petrochemicals.
What is caustic soda? Caustic soda is the chemical compound sodium hydroxide (NaOH). This compound is an alkali – a type of base that can neutralize acids and is soluble in water. Today caustic soda can be manufactured in the form of pellets, flakes, powders, solutions and more.
(c) Heavy chemicals are chemicals used extensively in industries and are. produced in very large quantities. Fine chemicals are chemicals produced in small quantities for specific purposes. and to a very high degree of purity.
These chemical factors can stimulate microbial growth and may cause an increase in the production of odorous metabolites by these organisms. In addition, such factors as pH, temperature, and dissolved oxygen may be critical for optimal growth of the microorganisms and production of odor compounds.
2020 chemical sales: $67.5 billion. For the second year in a row, BASF leads the Global Top 50 as the world's largest chemical maker.
