The Transesterification Reaction Of Ethyl Acetate 2 75 Gl With N Butanol 2 75 G Was Carried Out In The Lab At The En 1 (67.87 KiB) Viewed 72 times

The transesterification reaction of ethyl acetate (2.75 gl with n-butanol [2.75 g) was carried out in the lab. At the end of the experiment, a 3.20 g product mixture of butyl acetate and ethanol was obtained and subjected to a GC analysis using an instrument equipped with a thermal conductivity detector (TCD). The chromatogram was recorded on a chart recorder, which was fed with paper at a rate of 120 mm per minute. A mark was made on the chart when the sample was injected. Use this information to answer questions 18 - 20. OH OH ethyl acetate MW 88.11 g/mol bp 77 °C n-butanol MW 74.12 g/mol bp 118 °C butyl acetate MW 116.16 g/mol bp 126 °C ethanol MW 46.07 g/mol bp 78 °C 18. The first peak on the chromatogram was observed at a distance of 7.81 cm from the injection point marked on the chart, and the second peak was observed at a distance of 14.88 cm from the injection point.
