Reactors for Vacuum Reactions, Reduced-Pressure Operation, and Solvent Removal

Why Vacuum Chemistry Requires Specialized Batch Reactors

Certain reactions proceed more efficiently under vacuum, including those involving temperature-sensitive intermediates or equilibrium constraints. Vacuum operation improves solvent evaporation rates, reduces boiling points, and enables purification steps prior to downstream processing. Sealing systems, materials, and agitation must be compatible with reduced-pressure environments.

Frequently Asked Questions

Q: What materials are available for vacuum-rated reactors?

A: We offer carbon steel, 304 and 316 stainless steel, duplex stainless steels, Hastelloy, Inconel, titanium, and other alloys selected for solvent, catalyst, and reduced-pressure compatibility.

Q: What sizes do you manufacture?

A: We manufacture reactors from pilot scale (50 gallons) through production scale (15,000+ gallons). Custom sizes are engineered to match application requirements.

Q: What pressure and temperature ratings are available?

A: Standard designs support full vacuum to 5,000 psig and temperatures from cryogenic to 1,000°F. Enhanced ratings are available for specialty reduced-pressure applications.

Q: Do you provide engineering support for reactor specification?

A: Yes. Our engineering team works with process chemists and engineers to specify optimal reactor design including materials, heat transfer, mixing, and solvent removal systems.

Q: What is typical lead time for batch reactor manufacturing?

A: Lead times typically range from 16–24 weeks depending on size, materials, and complexity. Expedited schedules can be accommodated for urgent requirements.
