Abstract

1471265 Sulphonation of 1,4-dihydroxy anthraquinones IMPERIAL CHEMICAL INDUSTRIES Ltd 18 April 1974 [3 May 1973] 21015/73 Heading C2C The magnesium salt of a compound of formula where R is H, halogen or alkyl and the -SO 3 H group is in the 6- or 7-position, is prepared by reacting with 15-30% oleum in the presence of boric acid and a mercury compound at 150-200‹ C. and precipitating the desired salt from an aqueous solution of the reaction product. The latter is usually drowned into an ice/water mixture and a magnesium salt such as MgCl 2 or MgSO 4 added to effect precipitation. The boric acid used may be ortho- or meta-boric acid and the mercury compound (which may be recovered from the reaction mixture) may be mercuric oxide or mercuric sulphate.
