Preparation of Esters Introduction Esters are known for their pleasant smells such as perfumes and artificial flavorings in contained labs. They are formed when a carboxylic acid reacts with alcohol and a strong acid such as a catalyst called sulfuric acid (H2SO4) for this lab. The structural formula for esters can be represented as R-COO-R’. The R and R’ symbolizes different alkyl groups that can be combined to the ester. When naming an ester the first part comes from the alcohol followed

(throughput goes up or capacity goes down). Little’s Law: I = R x T (congestion = arrival rate x delay). Little’s Law is I = R*T (where I = avg inventory‚ r = throughput rate‚ t = avg flowtime). Delay explodes as the arrival rate approaches the system capacity: Delay ≈ 1/(capacity–arrival rate). The utilization
