Scaling up exothermic additions in the lab
15 Minute Webinar
Adding liquids to a reaction mixture is integral to synthetic chemistry. Scaling up from ml to L will often require changes in how these additions need to be made.
From initiating a reaction, quenching, or adding antisolvent as part of a crystallisation, we need to consider consistent and reproducible dosing.
A chemist may face issues with containment, holding temperature of feed stock, viscosity, mass and how to control highly reactive material.
Other considerations might include:
- manual handling
- volumetric vs gravimetric
- pressure equalisation
- which pumps to use
- tubing specifications
- controlling and recording exotherms
- controlling pH
- scalable batch repeatability
In this short webinar Steve and Jenna discuss considerations for making controlled liquid additions, give a demo of AVA Lab Control Software, with a case study illustrating how laboratory control software can solve everyday lab problems, and how Radleys helps address the needs of a typical chemist.
The case study from a customer, demonstrates automated liquid additions to a batch process, with built in safety overrides to control reaction exotherms.
Steve joined Radleys in 2006 as International Territory Manager for the Americas, India and parts of Europe. He has a passion for chemistry and in particular helping solve the challenging technical issues that chemists face in the laboratory.
