1-Phenyl-1,3-eicosanedione Use and Manufacturing
10125] The experimental apparatus consists of a classic glass, double jacketed chemical engineering reactor with a volume of 1 litre with an effective mixing system. This is topped with a separating column fitted with a variable-reflux condenser. It also has a recirculating loop fitted with a gear- type pump and a 600 W microwave generatotj0126] Add 440 mL xylenes, 178.76 g thsed methyl stearate and 42.87 g powdered sodium methoxide. Once the reagents have been added, render the reactor inert with a continuous flow of nitrogen gas. Recirculate the mixture through the external circuit at a rate of 15 kg/h. Bring to boiling and total reflux, and then switch the microwave sourceon.j0127] Add 68.45 g acetophenone over one hour. Once it has all been added, let the reaction continue for another 15 minutes. Throughout this time, draw any methanol and ethanol generated off the reaction mixture. After the 15 minutes of finishing time, switch off the microwave source and the heatet Acidify the mixture and then wash it.j0128] Analysis by gas phase chromatography shows that almost all the aceto-phenone is consumed and that the SBM titre is 98.3percent.10129] SBM productivity during the reaction phase is 173.2 kghm3.Example 6
