| titleOfInvention |
Alkali metal polyol salt and preparation method thereof |
| abstract |
An alkali metal polyol salt compound useful as a catalyst for aldol condensation reaction having the general formula: (MO) xR 1 (R 2 )(R 3 ) (OH) n. Wherein M is an alkali metal, R 1 Is C 2 ‑C 20 Alkyl radical, R 2 And R 3 Is straight-chain or branched C 1 ‑C 5 Alkyl of R 2 And R 3 May be the same. The number of hydroxyl groups in the alkali metal polyol salt compound is less than the number of hydroxyl groups in the starting alcohol, x + n is the number of hydroxyl groups in the starting alcohol, x is not less than 1, and n is not less than 0. The invention also relates to a preparation method of the compound. Due to the fact thatThe alcohol generated by the hydrolysis of the catalyst has a boiling point higher than that of the aldol condensation reaction material, so that the recovery of the reaction material is easily realized. |
