Question

c. Furfural (1) is an important chemical feedstock that can be used to synthesize a varn important derivatives. It can be prepared in large quantities by treating agricultural byproducts (bran, oat hulls, corncobs, etc.) with dilute acid. FUN FACT: the first commercial process for the manufacture of furfural was developed in 1922 by the Quaker Oats Company! 2-methyl furan (2) is a product of high interest that is used as an additive to increase the octane index of gasoline. Use the following conversion of furfural to 2-methylfuran to answer the following Iwo questions: H2, CuO/Zno Catalyst CH3 200°C Furfural bp. 162 2 2-methylfuran b.p. 65 i. What type of distillation method would one use to separate the product from trace amounts of starting material? Explain. (4 points) ii. What type of distillation method would one use to separate the product from a 50/50 mixture of starting material? Explain. (4 points)

Explanation / Answer

For removing trace amount of starting material fractional disstilation is sufficient, since at 65 degree celusius 2-methyl furan will be evaported and condensed

For 50:50 mixture the product can be separated by vacuum distillation method by appling high vaccum
