Abstract: Disclosed are novel intermediates and their preparation, and the preparation therefrom of 2-halo-3-nitro-5-acyl thiophenes which themselves are important intermediates for the preparation of azo dyes of the type, ##STR1## wherein C.sup.1 represents typically any aniline, tetrahydroquinoline, benzomorpholine or the like coupler and the acyl group contains from 1-10 carbons. It has been found that if 2-acyl thiophene is treated with a hydroxylamine compound, e.g., a salt of hydroxylamine, including sulphate, chloride or the like, to form the oxime prior to the 2-position halogenation and 3-position nitration steps, various side reactions such as halogenation of the acyl group and nitration of the 5-position are avoided, the yield of each step is improved, and the reactions are less sensitive to the deleterious effects of temperature variations and excess reactants. The oxime derivative is readily reconverted to the acyl derivative after the halogenation and nitration steps have been completed.

Abstract: Disclosed is a process for the recovery of residual rhodium from tar obtained by submitting a rhodium-containing catalyst-tar solution to an extraction using methyl iodide and aqueous hydrogen iodide, thereby recovering catalyst values in the aqueous phase and tar containing residual rhodium in the methyl iodide phase. The residual rhodium-containing tar is submitted to an extraction using a water-immiscible, inert solvent for the tar and aqueous ammonia to obtain residual rhodium in the aqueous phase. The catalyst-tar solution employed is derived from a production system in which acetic anhydride is prepared by carbonylating methyl acetate in the presence of rhodium, lithium and methyl iodide.
