PROCESS FOR THE PREPARATION OF TERTIARY PHOSPHINE OXIDES |
摘要 |
<p>Tertiary phosphine oxides are prepared by oxidation of tertiary phosphine sulfides using H2O2 in a solvent comprising about 2 - 20% by weight of optionally halogenated lower aliphatic carboxylic acids and the remainder of mono- or polyhydric aliphatic or cycloaliphatic alcohols if appropriate in mixtures with other inert solvents which are miscible with the carboxylic acid/alcohol mixture. Preferred solvents comprise acetic acicl/methanol and acetic acid/ethanol mixtures. The reaction products are final products and intermediates products in various specialized fields such as, for example, the plant protection sector and the polymers sector.</p> |
