Microjets device

Figure 8.1.23 depicts the ultrasound enhancement factor Eus as a function of the surface activation degree with parameter f2. The circles represent measured values for Eus and . In the case of magnesium as the treated sohd with tetrahy-drofurane as solvent and different chlorobutanes as reactants a mechanical activation degree of approximately 10% has been observed. This means that 10% of the necessary activation energy has been delivered by the mechanical treatment by impinging liquid microjets. This is a typical value that can be found in other devices like reaction mills, too. This value of 4 to 6kJ/mol for mechanically treated...
