2-sec-Butyl-phenol

Dinoseb is manufactured by the direct nitration of a watery emulsion of 2-sec-butyl phenol with diluted nitric acid (Boileau and Aubertein, 1961). 

While monometallic ruthenium/carbon deactivated progressively during 300 h on stream when the reaction was performed in 2-sec-butyl-phenol solvent at 180 °C and 3.5 MPa in a flow fixed-bed reactor, bimetallic ruthenium-tin/carbon catalysts exhibited a stable activity. The optimised ruthenium/tin atomic ratio of unity led to ruthenium and RuaSng alloy species. Neither tin nor ruthenium leaching occurred. In addition, the hydrogenation of the C=0 bond of levulinic acid was 100% selective.

One 1-ml aliquot is added to 1.0 ml of freshly-distilled 1,2-dibromo-ethane (bp 132°C) in an oven-dried flask which contains a static atmosphere of nitrogen or argon. After the resulting solution has been allowed to stand at 25°C for 5 min, it Is diluted with 10 rat of water and titrated for base content (residual base) to a phenolphthalein endpoint with standard 0.100 M hydrochloric acid. The second 1-mL aliquot is added cautiously to 10 ml of water and then titrated for base content (total base) to a phenol phthalein endpoint with standard aqueous 0.100 M hydrochloric acid. The methyllithium concentration is the difference between the total base and residual base concentrations.2 Alternatively, the methynithiura concentration may be determined by titration with a standard solution of sec-butyl alcohol employing 2,2 -bipyridyl as an indicator.

Distribution of cesium in the batch tests remained constant within experimental error in addition, no third-phase formation was observed. The solvent concentrations of calix[4]arene-bis-(rm-octylbenzo-crown-6) and l-(2,2,3,3-tetrafluoroproproxy)-3-(4-sec-butylphenoxy)-2-propanol remained constant within experimental error. Solvent degradation with irradiation was evidenced by a decrease TOA concentration decrease and an degradation product (4-ver-butyl phenol) increase in the solvent phase. No decline in extraction or scrubbing performance of the irradiated solvents was observed. The stripping performance of the solvent was seriously impaired with irradiation however, a mild caustic wash and replenishment of the TOA concentration restored the ability to strip the irradiated solvent.
