During Caffeine extraction and purification under the workflow of; steeping tea, L-L extraction, Add NaOH, dry, use roto-vap, recrystallization, and then recovering the crystals with dichloromethane what could be some potential reasons for caffeine loss when comparing to theoretical yield (0.034g) and what can be some possible reasons for the crude yield weighing in higher (0.05g) than the expected theoretical yield therefore giving an above 100 percent yield after doing the exact calculation
Reasons for caffeine loss

Experiment . the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction - (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents. This means that (unlike LAH or Grignard reactions) no separate...
