Another yellow liquid came over at about 160 C. My thermometer only read to 150 C, so this could be off. The bp of 4-heptanol is 156 C, so this may
have been my product. However, after at least half an hour of sluggish dripping, the temperature rose while I wasn't paying attention, broke the bulb
off my thermometer, and yellow liquid started dripping more vigorously. Presumably this is something else with a bp > 170 C, which contaminated my
product when it distilled over. I only got maybe 4 mL in total anyway, so I'm not going to bother distilling again to separate the two. The mixture
smells like a combination of an alcohol and sweaty socks left to fester for a long time.
