The Anton Paar Synthos 3000 (Fig. 3.16 and Table 3.5) is the most recent multi-mode instrument to come onto the market. It is a microwave reactor dedicated for scaled-up synthesis in quantities of up to approximately 250 g per run and designed for chemistry under high-pressure and high-temperature conditions. The instrument enables direct scaling-up of already elaborated and optimized reaction protocols from single-mode cavities without changing the reaction parameters. 

Temperature control Immersed gas balloon thermometer (max. 300 °C) outside IR remote sensor (max. 400 °C) 

Cooling system 190 m3 h I (forced air flow through rotor, 4 steps adjustable) 

External PC Optional, not required as key panel + keyboard is standard equipment 

Temperature measurement is achieved by means of a remote IR sensor beneath the lower outer surface of the vessels. The operation limit of the IR sensor is 400 °C, but it is regulated by the software safety features to 280 °C as the operation limits of the materials used are around 300 °C. For additional control, temperature measurement in a reference vessel by means of an immersed gas-balloon thermometer is available. The operational limit of this temperature probe is 310 °C, making it suitable for reactions under extreme temperature and pressure conditions.

Zeta potential measurements. The zeta potential f of the sample surfaces was determined by the streaming potential method, using a clamping cell connected with an EKA electrokinetic analyzer (Anton Paar GmbH, Graz, Austria). In this cell the sample is pressed against a PMMA spacer with seven channels. The measurements were performed with a KC1 electrolyte solution (10-3 M, 500 mL). The pH was adjusted to about 10 by adding NaOH (0.1 M,...

The solvent viscosity was measured by an Automated Microviscometer AMVn (Anton Paar GmbH, Austria, Graz) that is based on the rolling-ball principle. The diameter of the capillary having an inclination of 30° or 40° and ball were 1.8 mm and 1.5 mm, respectively. The filled solvent in the capillary was kept at 60 °C for 15 min before measurements. All measured values were calibrated by the value of EGi (4.95 mPas) at 60 °C. The accuracy was 1%, which was taken into account when the diflusion coefficients were converted to the hydrodynamic radii.
