ABSTRACT
A substance or material used in the post-processing of a chemical reaction typically in work-up procedures involving washing or extraction and in purification procedures involving chromatography or recrystallization. A product formed in a reaction between reagents as a direct mechanistic consequence of producing the target product assuming a balanced chemical equation that accounts for the production of that target product. Coupled products arise as a mechanistic consequence of producing the desired target product in a chemical reaction. Feedstocks refer to first, second, and third generation high volume industrial commodity chemicals available from the petrochemical industry. In a chemical reaction, the reagent that has the least number of moles associated with it corrected for its associated stoichiometric coefficient in a balanced chemical equation. A reactant or reagent is a chemical substance that appears on the left-hand side of a balanced chemical equation.
