Tert-butyl Hydroperoxide Industrial
Tert-butyl Hydroperoxideis a hydroperoxide, in fact one of the most widely used in a variety of oxidation processes, for example the Halcon process.It is normally supplied as a 69–70% aqueous solution. Compared to hydrogen peroxide and organic peracids, Tert-butyl Hydroperoxide is less reactive and more soluble in organic solvents. Overall, it is renowned for the convenient handling properties of its solutions. Its solutions in organic solvents are highly stable.
Industrially, tert-butyl hydroperoxide is used to prepare propylene oxide. In the Halcon process, molybdenum-based catalysts are used for the reaction.
On a much smaller scale, tert-butyl hydroperoxide is used to produce some fine chemicals by the Sharpless epoxidation.
TBHP Is a volatile, yellowish liquid ,it is alkyl hydroperoxide initator for polymerization of acrylic emulsion ,and wiedely used as raw material for organic peroxides synthesis.
Miscible with organic solvents such as alcohols,esters,olefins and NAOH solution.Slightly miscible with water.

All You Need to Know About ProPortâ„¢ Casings
Viking Pump’s latest generation of internal gear pumps (sizes H-QS in steel and stainless steel) brings a range of advantages that previous alloy pumps couldn’t offer, particularly in terms of porting flexibility. These new pumps have reduced the number of casing configurations, which helps lower manufacturing complexity, cost, and lead times, while simultaneously increasing the number of porting options and providing greater flexibility.
Because Viking pumps can handle a wide range of viscosities, users requested the option of smaller ports for low viscosity liquids to reduce piping costs, or larger ports for high viscosity liquids to minimize friction losses and power requirements. This meant that each pump size needed multiple port size options, as well as ports conforming to different global standards and pressure/temperature ratings.
One of the main reasons for the many casing configurations Viking Pump used in the past was that the ports were integrally cast into the casing, meaning every pump size had unique casings for each port size, standard, and rating. This led to an overwhelming number of casings to meet global needs.
The major change that led to the new ProPort™ casings is the use of bolt-on instead of cast-in ports. This significantly reduced the number of unique casings from 372 to just 14. That’s a huge improvement—going from 372 to 14 unique casings. This allows distributors to stock a range of sizes with the ability to quickly change ports to meet customers' specific piping needs.
For example, the new K and KK size pumps now feature bolt-on 2†NPT ports; ANSI-compatible Class 150 raised-face flanges in 2â€, 2-1/2â€, 3â€, and 4†sizes; Class 300 in 2â€, 2-1/2â€, and 3†sizes; and DIN 50, 65, and 80 PN16 ports. Now, instead of many casings, one casing is used on both K and KK sizes, offering 11 bolt-on port options, with internal porting sized to accommodate the largest available port. See the table below for available ports.

Key Benefits of ProPortâ„¢ Casings:
In addition to the flexibility, lead time, and price reduction benefits, here are some additional reasons for switching to the Modular pumps’ ProPort™ Casings:
- The removable NPT threaded ports on H-L size pumps eliminate the need for unions in the suction and discharge lines that were previously required to remove an NPT-ported pump.
- Since all ports can be re-used, if a replacement pump is needed, it can be ordered with fewer ports to further reduce cost.
- The bolt-on ports can be sealed by gaskets or O-rings and were designed and tested to ensure nozzle load ratings exceed ASME, DIN, and other global standards.
- Your distributor can provide enlarged suction ports to minimize friction losses that decrease NPSHa and can cause cavitation, while using smaller sized discharge ports to keep piping costs low.
Another key feature of the ProPortâ„¢ casing is the availability of opposite port models in all sizes, from H through QS. Previously, such models were either limited or had longer lead times and higher prices. By reducing the number of casings from 372 to 14, Viking Pump actually added more opposite port options, making it easier and more cost-effective for customers.
Additionally, the new ProPortâ„¢ casings are completely retrofittable onto existing Viking pumps. This means you can upgrade your current system without replacing the entire pump.
In terms of sealing, the new ProPortâ„¢ casings are gasketed but also include standard O-ring grooves, allowing for static O-ring seals if required. This gives users more flexibility depending on their application.
Casing drains, which were once optional and added cost and lead time, are now standard. This enables near-complete draining before removing a pump for maintenance, improving operator safety and minimizing spills on site.
Finally, the new casings feature drilled holes from the suction and discharge ports to the area behind the rotor, plugged with removable setscrews as standard. This allows users to experiment with the best combination of flush and/or suckback if needed, especially for materials like latex or chocolate that can set up in the rotor area.
