Patent GB-626772-A (GB)
Title: A process for preparing unsaturated acid halides
IPC: C07C51/58
Filed: 1947-04-11
Abstract: Unsaturated acid halides with an olefinic carbon atom directly linked to the carbonyl group are prepared by treating an unsaturated aldehyde of the formula <FORM:0626772/IV (b)/1> (where R1, R2 and R3 are hydrogen, halogen alkyl, cycloalkyl, aryl or aralkyl and R1 and R3 may be portions of a non-aromatic ring) with chlorine or bromine at an elevated temperature between about 200-600 DEG  C.  Specified aldehydes include the following: a -methyl-, a -ethyl-, a -isopropyl-, a  : b -dimethyl-, and a  : b -diethyl-crotonaldehyde and similar aldehydes where R1, R2 and R3 are hydrogen or aliphatic radicals, e.g. methyl to butyl.  Aldehydes containing rings include 1-formylcyclohexene-1, and others in which R1, R2 and R3 are for example phenyl, tolyl, xylyl or benzyl, e.g. b -phenyl acrolein or crotonaldehyde.  The aldehyde may be substituted by halogen, as in the conversion of a -chlorocrotonaldehyde to a -chlorocrotonyl bromide.  The preferred starting materials, however, are acrolein, methacrolein and crotonaldehyde.  The preferred reaction temperature lies between 250 DEG  and 500 DEG  C., e.g. 250-400 DEG  C.  One or both of the reactants are preferably preheated in the vapour phase, or the halogen may be continuously introduced into a liquid aldehyde stream and then heated to 250-500 DEG  C.  Either excess aldehyde or halogen may be employed, but it is preferred to use a ratio of aldehyde to halogen of ca. 1 : 1 to 5 : 1, e.g. 2 : 1, and the contact time is made as short as possible consistent with halogenation of the formyl hydrogen.  In the examples: (1) acrolein is chlorinated at 320 DEG  C. to give acrylyl chloride; (2) methacrolein is chlorinated at 400-470 DEG  C. to give methacrylyl chloride and (3) crotonaldehyde is brominated at 300-450 DEG  C. to give crotonyl bromide.
