Mixer-Reactor Chip Improves Control of Rapid Highly Exothermic Reactions

Uniqsis Ltd

17/06/2013

Uniqsis Ltd. has demonstrated how its proprietary glass static mixer-reactor chip technology can be used to perform highly exothermic reactions more conveniently at higher temperatures with useful throughputs under continuous flow-through conditions.To achieve high reproducibility and facilitate scale up, it is important to control both mixing and temperature, particularly for highly exothermic or rapid mixing-dependent reactions (‘Type A’ reactions). Where the...

Safe and High Yielding Flow Nitration Methodology

Uniqsis Ltd

14/05/2013

Uniqsis has published details of a mild nitration method using its FlowSyn flow chemistry system that enables short reaction times and high conversion to be achieved whilst minimising the amount of corrosive (and potentially explosive) hot nitrating mixture present in the reactor at any one time.Nitration is an important synthetic procedure that is often difficult to control. Under continuous flow-through conditions, however, exotherms are typically well controlled and...

Automated Combinatorial Flow Chemistry

Uniqsis Ltd

29/04/2013

The FlowSyn Auto-LF loop filling module from Uniqsis is a powerful and highly efficient module that allows chemists to automatically perform in sequence combinatorial flow chemistry experiments. Each experiment can be run under different conditions and utilise a different set of reagents or monomers.Incorporating a separate liquid handler and fraction collector, FlowSyn Auto-LF enables sample loop filling in preparation for the next experiment to take place before the...

Flow Methodology for Highly Reproducible Bromination Reactions

Uniqsis Ltd

14/03/2013

Uniqsis has announced an application note that describes a continuous flow methodology for electrophilic bromination that offers excellent control of both temperature and mixing using a proprietary mixer chip, leading to a highly reproducible outcome.Electrophilic bromination is a useful reaction in organic synthesis. However, when molecular bromine is used as the electrophile, under acidic conditions, it can be difficult to control both the exothermic addition and to...

Uniqsis Ltd (Cambridge, UK), specialists in continuous flow chemistry equipment has announced another strong year of international trading with particular growth in sales to organisations in the USA, France, Italy and China.Launched in 2007 the company will celebrate five years of successful trading, based on its renowned FlowSyn™ continuous flow reactor systems, in April 2013. During this period, the company has not only developed the most comprehensive range of...

Promoting efficient gas dependent flow reactions

Uniqsis Ltd

29/01/2013

Uniqsis Ltd has announced a new Gas Addition Module for its FlowSyn continuous flow reactor range. The new module enables fast, controllable pre-saturation of liquid reagents with a wide range of gases thereby promoting efficient gas-dependent reactions in flow, such as carbonylation, hydrogenation, ozonolysis and direct synthesis of carboxylic acids.Mixing gas and liquids in a controllable and reliable manner has always posed a particular challenge for flow chemists, in...

Modular Flow Reactor Systems

Uniqsis Ltd

13/12/2012

Uniqsis has announced a new portfolio of modular flow systems, based around its Binary Pump Module (BPM) and FlowSyn™ flow reactor technology to provide users with greater flexibility and broader synthesis capabilities.Uniqsis developed the original two-channel FlowSyn™ flow reactor system as a fully integrated ‘one box’ solution to make the emerging technology of continuous flow chemistry easily accessible to anyone with an interest in exploring...
