Process for preparing potassium monoethyl malonate |
| abstract |
A process for preparing potassium monoethyl malonate by selective saponification of malonic acid diethyl ester with potassium hydroxide, in which the potassium hydroxide is added to the malonic acid diethyl ester, malonic acid diethyl ester and potassium hydroxide are used in a molar ratio of at least 1.5 and the potassium hydroxide is effectively distributed into the malonic acid diethyl ester. |
