phenoxy वाक्य

उदाहरण वाक्य

1. The search for an acid with a longer half life, i . e . a metabolically and environmentally more stable compound led to 2, 4-dichlorophenoxyacetic acid ( 2, 4-D ) and 2, 4, 5-trichlorophenoxyacetic acid ( 2, 4, 5-T ), both phenoxy herbicides and analogs of IAA . Robert Pokorny an industrial chemist for the C . B . Dolge Company in Westport, Connecticut published their synthesis in 1941.

3. The best known phenoxy herbicides are MCPA, 2, 4-dichlorophenoxyacetic acid ( 2, 4-D ) and 2, 4, 5-trichlorophenoxyacetic acid ( 2, 4, 5-T ) . 2, 4, 5-T was later found to be inherently contaminated with the 2, 3, 7, 8-tetrachlorodibenzo-para-dioxin ( TCDD ), and has since been banned in most countries . 2, 4-D may also contain dioxin impurities, depending on the production method.
