Recovery Of Selenium From Urethane Solutions

US Patent:
4041139, Aug 9, 1977
Filed:
Aug 30, 1976
Appl. No.:
5/718635
Inventors:
Thomas A. Washall - Wilmington DE
Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
C01B 1900
US Classification:
423508
Abstract:
A process for the recovery of selenium by liquid-liquid extraction from a urethane solution containing selenium compounds by contacting the selenium-containing urethane solution at a suitable temperature with water and a saturated aliphatic or alicyclic paraffin hydrocarbon or mixtures thereof. The selenium may be recovered from the resulting hydrocarbon phase in the form of selenium per se or selenium dioxide for reuse in the preparation of urethanes.

Removal Of Selenium From Urethane Solutions

US Patent:
4038377, Jul 26, 1977
Filed:
Sep 29, 1976
Appl. No.:
5/727811
Inventors:
Thomas A. Washall - Wilmington DE
Harry Morgan - Upper Darby PA
Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
C01B 1900
US Classification:
423510
Abstract:
A method for the removal and recovery of selenium by liquid-liquid extraction from a urethane containing selenium compound by contacting a hydrocarbon solvent solution of the selenium-containing urethane at a suitable temperature with an aqueous ammonium hydroxide or alkali metal hydroxide solution and recovering the selenium from the resulting selenium compound enriched aqueous hydroxide phase; the deselenized urethane remaining in hydrocarbon phase.

Removal Of Tellurium From Glycol Ester Solutions

US Patent:
4224301, Sep 23, 1980
Filed:
Aug 20, 1979
Appl. No.:
6/067658
Inventors:
Thomas A. Washall - Wilmington DE
Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
C01B 1900
US Classification:
423508
Abstract:
A method for the removal and recovery of tellurium from a vicinal glycol ester solution containing soluble tellurium compounds by contacting the tellurium-containing glycol ester solution at a suitable temperature with granular activated carbon to adsorb the soluble tellurium compounds. The tellurium may be recovered from the activated carbon and converted to a form suitable for reuse in the preparation of the vicinal glycol esters.

Process For The Recovery Of Selenium From Selenium-Containing Urethane Solutions

US Patent:
4038375, Jul 26, 1977
Filed:
Sep 15, 1976
Appl. No.:
5/723359
Inventors:
James H. Vorachek - Drexel Hill PA
Thomas A. Washall - Wilmington DE
Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
C01B 1900
US Classification:
423510
Abstract:
A process for the recovery of selenium from a urethane solution containing selenium compounds by contacting the selenium-containing urethane solution at a suitable temperature with an aqueous solution of a mercuric salt compound or mixtures thereof to form an insoluble precipitate of mercury-selenium compounds or complexes. The selenium and mercury may be recovered from the resulting precipitate in a form suitable for reuse in the preparation of urethanes and selenium removal respectively.
