| titleOfInvention | Process for the preparation of carbonyl compounds by cleavage of hydroxycarboxylic acids |
| abstract | Production of carbonyl compounds (I) comprises cleaving beta -hydroxy carboxylic acids or salts (II) in the presence of an alkali(ne earth) metal hydroxide, alkoxide, oxide, amide or hydride in a non-hydroxylic solvent. Production of carbonyl compounds of formula (I) comprises cleaving beta -hydroxy carboxylic acids or salts of formula (II) in the presence of an alkali(ne earth) metal hydroxide, alkoxide, oxide, amide or hydride in a non-hydroxylic solvent. R<1>R<2>C=O (I) R<1>R<2>C(OH)-CR<3>R<4>-COOM (II) R<1> = optionally halogen- or cyano-substituted 1-30C hydrocarbyl in which one or more non-adjacent CH2 groups can be replaced by O, CO, COO, OCO, OCOO, S or NR and one or more CH groups can be replaced by -N=, -N=N- or -P=; R<2> = H or R<1>; R<3>, R<4> = H, halogen or R<1>; R = H or optionally halogen- or cyano-substituted 1-30C hydrocarbyl in which one or more non-adjacent CH2 groups can be replaced by O, CO, COO, OCO, OCOO, S or NR' and one or more CH groups can be replaced by -N=, -N=N- or -P=; R' = 1-20C alkyl; and M = H, alkali(ne earth) metal or NH4. R<1>+R<2>, R<3>+R<4> or R<1>+R<3> can be joined together to form a ring. |
