Abstract: Multistep process for the preparation of butanedicarboxylic acid by the hydrogenation of carbon monoxide under pressure in the presence of a cobalt carbonyl catalyst, the improvement of heating at a temperature of 250 DEG to 350 DEG C. under superatmospheric pressure the resulting aqueous solution of cobalt carbonyl hydride that has been extracted with butadiene or with mixtures thereof before using in a subsequent step of the multistep process.

Abstract: The raw materials are mineral oil-carbon black suspensions formed in the splitting of hydrocarbons with air or oxygen by the submerged flame process, where they separate out on quenching the gas stream. Low-boiling hydrocarbons with unpleasant swell and detrimental to printing inks are pref. removed from the suspensions by stripping the hot product from the flame process with inert gases or by application of vacuum. The black obtained is weakly agglomerated and can be easily processed to printing ink pastes with optimum pigment dispersion by simple and fast dispersion methods.
