'''Trichloroacetyl chloride''' is the [[Chemistry:Acyl chloride|acyl chloride]] of [[Chemistry:Trichloroacetic acid|trichloroacetic acid]].  It can be formed by reacting [[Chemistry:Chlorine|chlorine]] with [[Chemistry:Acetyl chloride|acetyl chloride]] or [[Chemistry:Acetaldehyde|acetaldehyde]] in the presence of activated charcoal.  It is used in the manufacture of pharmaceuticals and plant protection compounds.<ref name="Ebmeyer">[http://www.freepatentsonline.com/5659078.html  US Patent No. 5,659,078] to Ebmeyer ''et al.'', "Process for the preparation of trichloroacetyl chloride," issued August 19, 1997 (as reproduced by freepatentsonline.com and retrieved on October 23, 2007).</ref>
