Hydrothermal synthesis is a technique that involves the growth of materials from aqueous solutions at elevated temperature and pressure. The term hydrothermal usually refers to any heterogeneous reaction in the presence of aqueous solvents and complexing agents under high pressure and temperature conditions to dissolve and recrystallize materials that are relatively insoluble under ordinary conditions. The hydrothermal technique is widely used for the synthesis of a variety of inorganic compounds, nanomaterials and zeolites. It is a highly interdisciplinary subject and the technique is popularly used by geologists, biologists, physicists, chemists, ceramists, hydrometallurgists, material scientists, engineers, and many others.

In addition to their normal uses for sample digestion and dissolution, Parr’s Acid Digestion Vessels haven proven to be an excellent means to perform hydrothermal synthesis. Learn more.

Parr’s Jim Nelson Interviewed by Chemical Today Magazine

Parr Multi Reactor Systems

Six Reactor Parallel System with Automated Sampling System
Six Reactor Parallel System with Automated Sampling System

Parr has seen a recent increase in demand for both parallel and series multi reactor systems. Parallel systems have been requested for use in high-throughput screening, combinatorial chemistry, corrosion testing, and catalyst testing. Multiple reactors plumbed in series have typically been configured as CSTR’s used for conducting multiple reactions sequentially. With this demand, we have designed and manufactured multi reactor systems using our largest stirred reactors (four 20L), to our smallest (six 25mL), and many in between.

Our multi reactor systems are used by combinatorial chemists at pharmaceutical companies, catalyst development researchers at petroleum companies, material scientists at polymer producers, production engineers at energy storage and mining companies, and academic researchers pursuing widely varied research avenues.

The Shift from Batch to Continuous-Flow Reactors

Recently, continuous-flow reactors have become commonplace in pharmaceutical laboratories and production facilities. This style of reactor permits easier automation of sequential and parametric changes in temperature, pressure, flow rate, and residence time. The amount of product becomes a function of time, not larger equipment, thereby leading to increased safety as smaller amounts of materials are present at any given time.

Parr Participates in Flow Chemistry Panel Discussion

Click to read the e-version!

Parr’s Senior Product Manager Steve Perry, Ph.D. was invited to participate in Chemistry Today’s Panel Discussion on manufacturing using flow chemistry in industrial applications. Some of the topics covered include the advantages of flow chemistry over batch processing, how to minimize risk when implementing a new technique, the role of modeling in flow process development, and what challenges remain in flow chemistry.

Stirred Reactors for Biomass Applications

In the biomass world, process inputs include a wide range of organic objects: from sticks and intact sugarcane stalks to ground wood pulp to viscous suspensions of algae. Each of these starting materials can require unique chemistry and mixing techniques to be properly agitated.

Parr's Stirred Reactors offer various loading and mixing options for biomass applications.

Dr. Andrei Yermalayeu

Dr. Yermalayeu is an expert in the field of thermodynamics and oxygen bomb calorimetry. His presentation "Combustion Calorimetry: Yesterday, Today, & Tomorrow" will include:

  • The origins of oxygen vessel combustion calorimetry including thermodynamic research and industrial R&D.

  • The changing role of coal testing.

  • Current applications.

  • Calorimeter user expectations and what they mean to the future of calorimetry.

We are excited for Dr. Yermalayeu's participation in these conferences to both learn and share with other leaders in the field of calorimetry.
