| titleOfInvention | Method for producing hydroxyphenylpropionate |
| abstract | [PROBLEMS] Spiroglycol (II) containing acid Even when is used, compound (IV) Of hydroxyphenylpropionate (I) with a low yield of Is provided. SOLUTION: Spiroglycol (II) is brought into contact with an alkali compound to obtain propionates (III). And react with. Spiroglycol (I) can be used without producing a product obtained by reacting pentaerythritol and hydroxypivalaldehyde in the presence of an acid catalyst. As alkali compounds, alkali metal carbonates, alkali metal bicarbonates, alkali metal hydroxides, Use alkaline earth metal carbonates and alkaline earth metal hydroxides. Spiro glycol is usually contacted with an alkali compound in a molten state. The reaction is usually performed in the presence of an organotin catalyst. |
