  INTRODUCTION
  Aldehydes belong to a class of organic compounds called carbonyls. Carbonyls, which
  include aldehydes and ketones, have the functional group �C �
  � O in their structure. In
  the aldehydes the carbonyl is in the end position so that any compound that contains one or
  more � C�
  � O function groups is described as an aldehyde, a dialdehyde if it contains two
  functional groups, or a trialdehyde if it contains three.
  Aldehydes include a number of saturated aliphatic, unsaturated aliphatic, aromatic, or
  cyclic compounds. Saturated aliphatic aldehydes include formaldehyde, acetaldehyde, propi-
  onaldehyde, butryraldehyde, valeraldehyde, and glutaraldehyde. Glutaraldehyde, as can be
  seen in Table 32.1, is a dialdehyde with carbonyls on both ends of the molecule. Other dialde-
  hydes include malonaldehyde and succinaldehyde. Unsaturated aliphatic
