PROCESS FOR THE PREPARATION OF 2-N-BUTYL-2-ETHYL-1,3-PROPANE DIOL |
摘要 |
<p>The invention relates to a novel process for the preparation of 2-n-butyl-2-ethyl-1,3-propane diol from 2-ethyl hexanal and formaldehyde by using a basic alkali metal hydroxide or earth alkali metal hydroxide catalyst. In the process according to the invention, cationic or neutral phase transfer catalysts are additionally used for promoting the reaction. The correct choice of the sources of the initial material ccomponents is also essential. 2-n-butyl-2-ethyl-1,3-propane diol is used, for example, in the paint industry in the preparation of pulverous paints.</p> |
