Safely Dose Unattended Exothermic Reactions By Eliminating Increases In Temperature

Share Article

Demand for safer, automated Chemical R&D in the organic synthesis lab includes the need for unattended dosing while controlling the reaction temperature. METTLER TOLEDO’s EasyMax and OptiMax synthesis workstations excel beyond the functionality of any round bottom flask by allowing unattended volumetric dosing of reactants while keeping the reaction temperature under a specified temperature - even for exothermic reactions.

Safely Dose Unattended Exothermic Reactions By Eliminating Increases In Temperature

The latest synthesis workstation touchscreen firmware allows the user to enter the maximum reaction temperature for a dosing operation, which is particularly advantageous for exothermic reactions.

METTLER TOLDEO is pleased to announce the availability of a new volumetric dosing algorithm for EasyMax and OptiMax synthesis workstations which allows unattended dosing combined with safe reaction temperature control.

The latest synthesis workstation touchscreen firmware allows the user to enter the maximum reaction temperature for a dosing operation, which is particularly advantageous for exothermic reactions. If the reaction exceeds the pre-programmed maximum temperature, dosing will pause and resume only after the reaction temperature cools down to below the maximum.

During an EasyMax or OptiMax experiment, scientists can run volumetric dosing with the plug-and-play operated Dosing Unit SP-50. Dosing can be started manually or pre-programmed as part of a task sequence. Dosing a specified amount of liquid can be controlled by dosing time or rate.

Strongly exothermic reactions can cause the reaction to rise above the desired temperature even with the powerful cooling capability of EasyMax and OptiMax. In some cases, such a rise in temperature could cause a decrease in reaction selectivity, formation of undesired products and even an uncontrollable reaction. The new functionality allows unattended dosing without any risk – even if there is no understanding of the exothermicity of a dosing controlled reaction. The dosing algorithm safely controls the reaction temperature.
