text: # Acylal
  
  Acylals in organic chemistry are a group of chemical compounds sharing a functional group with the general structure $RCH(OOCR)_2.$ Acylals are obtained by reaction of carbonyls with acetic anhydride or other acid anhydrides and a suitable catalyst, for instance with sulfated zirconia at low temperatures when used as protective groups for aldehydes. High temperature exposure converts the acylal back to the aldehyde.
