Definitions
- This publication mainly concerns the synthesis of dibenzoylmethane, which is known to correspond to an extremely favorable reaction, although some examples also relate to the synthesis of relatively close molecules; in particular an example relates to the synthesis of stearoylbenzoylmethane for which the title was only 45%.
- the second reason is related to the hydrodynamic conditions in the reactor: in fact beyond a dozen recirculation of the volume thereof per hour, the flow caused by the stirrer is disturbed.
- the process according to the invention is therefore particularly advantageous both from an economic point of view and from an ecological point of view.
- Example 1 Synthesis of Stearoylbenzoylmethane (SBM) by the "classical" method.
- SBM Stearoylbenzoylmethane
- a conventional 1-liter chemical glass reactor double wrapped and equipped with high-performance stirring, 450 ml of xylene, 178.79 g of molten methyl stearate and 34.05 g of sodium methoxide powder are introduced.
- the reactor is inerted by a slight flow of nitrogen continuously.
- the mixture is then boiled and refluxed at the top of the separation column.
- Acetophenone is introduced into the reactor at a rate of 68.42 g in 5 hours.
- the SBM titre of the process according to the invention is more than 15 points higher than that of the conventional process.
- the productivity obtained during the SBM reaction phase is 172.6 kg / h / m3, which is 5.7 times the productivity of the conventional process.
