This significantly increases space-time yield and production throughput, enabling you to achieve commercial-scale quantities with highly compact, continuous equipment.
We offer robust solutions for sensitive reactions traditionally requiring ultra-low temperatures, such as highly reactive organolithium chemistry. Flow reactors provide rapid, excellent heat exchange that prevents localized hot spots. This superior thermal control often allows these challenging reactions to safely run at higher, much more energy-efficient temperatures than the strict -78°C required in batch mode, all while preserving high product selectivity.
Our continuous processing services proactively support your corporate sustainability goals by aggressively minimizing solvent usage and seamlessly enabling closed-loop solvent recycling. By drastically reducing overall waste generation through highly improved reaction selectivity, our continuous manufacturing platforms align perfectly with modern green chemistry principles to significantly lower your process E-factor and environmental footprint.
We provide highly specialized, heavily monitored setups for safely handling explosive, toxic, or otherwise highly energetic reagents. By generating these volatile species strictly in situ and consuming them immediately within the controlled flow stream, we completely eliminate the need for dangerous bulk storage, hazardous transport, and extensive safety bunkering, easing your regulatory compliance burdens.
Partner with BOC Sciences to leverage the safety, speed, and consistency of flow chemistry. Whether you need route scouting or kilogram-scale production, our engineering expertise ensures successful project execution.
Minimal reactor volume drastically reduces the active chemical load at any given moment. Combined with excellent heat dissipation, this prevents thermal runaways in highly exothermic reactions.
Precise control over mixing and residence time leads to improved selectivity and purity profiles, often suppressing side reactions that are unavoidable in batch mixing.
Flow processes scale linearly by extending operation time or "numbering up" reactors. This eliminates the "scale-up effect" risks associated with heat and mass transfer changes in larger batch vessels.
Access novel process windows (high T/P) and forbidden chemistries. Reactions that are too slow or too dangerous for batch reactors become feasible and efficient in flow systems.
Client Needs: A client required the scale-up of an intermediate involving a highly exothermic nitration step. The reaction was deemed unsafe for existing batch reactors due to potential thermal runaway risks at the required scale.
Challenges: Strict temperature control was impossible in large batch vessels, leading to impurity formation and safety hazards. The client needed a method to manage the heat release while maintaining high throughput to meet production deadlines.
Solution: BOC Sciences designed a robust continuous flow process utilizing advanced silicon carbide micro-reactors known for their exceptionally high heat exchange capacity. We meticulously optimized the precise residence time and flow rates to instantly quench the highly reactive mixture immediately after completion, actively preventing over-nitration and unwanted side product formation.
Outcome: The process was successfully scaled to produce kilograms of material with a consistent purity profile. The flow setup effectively managed the exotherm, ensuring operational safety and eliminating the need for extensive safety bunkering.
Client Needs: A biotech firm needed to scale up a photo-redox catalyzed cyclization. The reaction worked well in milligram-scale vials but failed completely when attempted in 1-liter batch reactors due to poor light penetration (Beer-Lambert law limitations).
Challenges: The reaction required long irradiation times in batch, leading to degradation of the product. The client needed a solution that provided uniform light exposure at a multi-gram scale.
Solution: We implemented a customized continuous flow photoreactor system equipped with narrowly tuned, high-intensity LED arrays. The ultra-thin fluoropolymer tubing diameter ensured maximum, highly uniform light penetration across the entire moving reaction volume, completely overcoming Beer-Lambert limitations and significantly accelerating the reaction kinetics to drastically reduce total processing time.
Outcome: Reaction time was reduced from 12 hours (batch) to 20 minutes (flow). The yield increased by 30%, and the process was successfully run continuously to deliver the required quantity of the target compound.
Client Needs: A pharma client sought to optimize a lithiation-substitution reaction. The legacy batch process required cryogenic cooling to -78°C to prevent impurity formation, which was energy-intensive and difficult to maintain at scale.
Challenges: Slow mixing in the batch reactor caused localized hot spots, leading to competitive side reactions. The client wanted to reduce energy costs and improve the impurity profile.
Solution: BOC Sciences utilized a specialized flow reactor equipped with an active micromixer to achieve instantaneous, highly homogeneous mixing. This superior mass and heat transfer environment effectively eliminated localized hot spots, allowing the sensitive organometallic reaction to be successfully performed at a much milder -20°C without sacrificing product yield or target selectivity.
Outcome: The "flash chemistry" approach improved selectivity and yield. Operating at -20°C instead of -78°C significantly reduced energy consumption and simplified the cooling infrastructure required for production.
Leveraging the linear scale-up effect of continuous flow, we bypass heat and mass transfer limitations common in batch reactors by increasing parallel channels or optimizing holdup volume. BOC Sciences utilizes diverse micro-reactors and continuous systems to simulate fluid dynamics, ensuring seamless parameter transition across scales while minimizing technical risks during process intensification.
Flow chemistry provides superior heat exchange due to its high surface-area-to-volume ratio, allowing instantaneous heat removal to prevent hotspots and side reactions. Our services include sophisticated modeling for energetic reactions like nitrations, enhancing process safety and stability through precise integration of flow rates and advanced thermal control units.
For reactions involving gases like $H_2$, $O_3$, or $CO$, BOC Sciences employs efficient continuous mixing technologies to maximize interfacial contact and gas dissolution rates. By managing back-pressure and gas flow, we achieve dynamic pressure regulation, shortening reaction times and eliminating safety hazards associated with gas accumulation in traditional high-pressure autoclaves.
We utilize multi-step continuous synthesis to achieve "in-situ generation and consumption" of labile or toxic intermediates. This "telescoped" approach minimizes residence time and inventory, preventing decomposition during offline isolation. BOC Sciences can integrate multi-stage reactors to chain complex synthetic routes, ensuring high efficiency and operational safety.
Continuous flow overcomes penetration depth limitations in photochemistry by using narrow channels to ensure uniform light exposure. BOC Sciences’ platform features multi-wavelength light sources and precise residence time control, significantly increasing quantum yield and reducing over-irradiation byproducts.
