摘要: The disclosure provides a process for removing dissolved niobium, titanium, and zirconium impurities from an iron chloride solution having an iron concentration of about 50 to about 250 grams/liter comprising: (a) heating the iron chloride solution comprising a compound selected from the group consisting of a niobium compound, titanium compound, zirconium compound, and mixtures thereof, in a vessel, at a temperature of about 120° C. to about 300° C., and at least autogenous pressure, to precipitate the compound as a solid; and (b) separating the solid from the iron chloride solution. The separation of the solid is accomplished by filtration, settling, or centrifugation. In one embodiment, the iron chloride solution is a byproduct of the chlorination process for making titanium dioxide.

摘要: The process and product are disclosed for mounting free-flowing particles, which employ a support having a support surface with an array of tacky areas which have a size and bonding strength suitable for adhesion of either one or two of said particles. In the process the particles flow across the support surface to allow particles to contact the tacky areas and adhere thereto. An array of mounted particles may thus be provided which has at least 50% singly or doubly mounted particles.

摘要: Described is a cyclic process for preparing p-phenylenediamine from aniline and ammonia including aminating iodoaniline, recovering the iodide from the amination, and electrolyzing the iodide with aniline back to iodoaniline. Also described are the two basic reactions of the cyclic process, a new process for preparing phenylenediamines by the amination of the corresponding iodoanilines with ammonia in the presence of copper metal or a copper(I) salt and a new process for preparing p-iodoaniline by electrolysis of aniline with ammonium iodide as well as a new compound useful in the amination.
