Versuchsvorschrift

One part of β-(2-oxocyclododecyl)propionic acid, 1 part of acetic anhydride, 10 parts of glacial acetic acid, and 0.5 part of Amberlyst 15 were allowed to react at 50° C for 4 hours and the reaction solution was withdrawn and analyzed by gas chromatography to find that β-(2-oxocyclododecyl)propionic acid was not present and 13-oxabicyclo(10.4.0)hexadec-1(12)-en-14-one was produced in 99% selectivity.

Aufarbeitung

  1. customto react at 50° C for 4 hours
  2. customthe reaction solution was withdrawn
