WebThe synthesis of Fischer indole is an organic reaction used by an acid catalyst to convert phenyl hydrazine and an aldehyde or ketone to an indole. By the acid catalysed reaction of the hydrazine with the carbonyl, the cycle starts with the formation of a phenylhydrazone. Why do bacteria produce indole? WebThe water–gas shift reaction (WGSR) describes the reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen: CO + H 2 O ⇌ CO 2 + H 2. ... In the Fischer–Tropsch process, the WGSR is one of the most important reactions used to balance the H 2 /CO ratio. It provides a source of hydrogen at the expense of carbon ...
