Definitions
- This invention relates to a method of recovering a photographic addendum from a dispersion thereof.
- a method of recovering a water-insoluble organic compound from a dispersion of a mixture thereof with an oil-former in an aqueous medium containing a hydrophilic colloid and a surface active agent which comprises adding to the liquid dispersion an oleophilic non-ionic surface active agent so as to cause crystallization of the organic compound.
- the compound to be recovered After the compound to be recovered has crystallised, it may be filtered and washed with warm water to remove the hydrophilic colloid and any water soluble surface-active agent. It may also be washed with an organic solvent having a low solvent power for the compound being recovered but a high solvent power for the oleophilic surface active agent. Hydrocarbon solvents such as petroleum ether, hexane and heptane are suitable in many instances. Often, the dried recovered compound is sufficiently pure for reuse without further treatment.
- the invention is illustrated by the following
- Cyan dye-forming coupler 2-[ ⁇ -(2,4-di-tert-amyl- phenoxy)-butyramido]-4,6- dichlcro-5-methylphenol.
- Oil former dibutylphthalate.
