Fischer–Tropsch plants associated with coal or related solid feedstocks (sources of carbon) must first convert the solid fuel into gases. These gases include CO, H2, and alkanes. This conversion is called gasification. Synthesis gas ("syngas") is obtained from coal gasification is a mixture of hydrogen and carbon monoxide. The H2:CO ratio is adjusted using the water-gas shift reaction.

WebFischer (1852-1919) who devised it. In this experiment you will synthesize the ester, n-butyl acetate (bp 126.5°C), from acetic acid (bp. 118.1°C) and n-butyl alcohol (bp. 117.7°C) using sulfuric acid as a catalyst (equation 2). (In other words, you are carrying out equation 1 using R = methyl and R’ = n-butyl.) WebQuestion: If you look at a reaction equation for a Fischer esterification reaction, you cannot tell where the singly bonded oxygen comes from (acid or alcohol).
