HFIP (hexafluoroisopropanol) is one of the few solvents that can dissolve many crystalline polymers. HFIP is an expensive solvent, with a price of around 100,000 yen per kilogram. While it is likely possible to purify and reuse HFIP by setting up a glass distillation apparatus yourself, many research and development environments face challenges in doing so. By introducing "Solpure," it is possible to significantly enhance the convenience, safety, and precision of HFIP distillation and purification. **Issues during HFIP distillation and purification:** - Due to its weight, a sturdy fixation is necessary when setting up larger equipment. - Care must be taken with pipes, seals, and grease that come into contact with HFIP vapor. - Although its toxicity is low, it has a strong odor and corrosiveness, making handling difficult. - It easily absorbs water, so a process to remove water is usually required. - Quality checks after purification are necessary. - Distillation and purification of one gallon bottle takes about two days. - High costs are incurred even when disposing of waste. *For more details, please refer to the PDF document or feel free to contact us.*

We purify and recover expensive solvents, such as deuterated solvents used in NMR measurements, which are used in small quantities for reuse. Here, we introduce the example of DMSO-d6. DMSO-d6 (deuterated dimethyl sulfoxide) is a solvent used in NMR measurements, with a boiling point of 189°C and a melting point of 20°C. By using "Salt Mini," it is easy to purify, recover, and reuse DMSO-d6. Simply set the waste solvent and turn on the power; after that, you can leave it completely unattended while safely purifying the solvent at normal pressure and low temperature. [Recommended conditions for DMSO purification using Salt Mini] ■ Evaporation section (heating section) set temperature: 80°C… a temperature that achieves a practical purification rate ■ Condensation section (cooling section) set temperature: 21°C… DMSO-d6's freezing point = 20°C ■ Air blowing amount setting value: 7.0–9.0… equivalent to a flow rate of 1.8–2.1 L/min ■ Pressure: normal pressure… standard condition for Salt Mini *For more details, please refer to the PDF document or feel free to contact us.

• Gas recovery/treatment equipment

We would like to introduce a case of zero-emission organic solvents, which has achieved almost complete elimination of the release of organic solvents into the atmosphere by combining the rotary evaporator commonly used in chemical laboratories with the "Cool Trap OSR-CT125." The stainless steel high-efficiency condenser, developed with our proprietary technology, features approximately 100 times better heat exchange efficiency compared to standard glass condensers when cooling and trapping organic solvent gases.

(2) Concentration can be performed without being limited by installation location due to closed-system concentration. (3) Generate debris-free single crystals in a short time. (4) For X-ray analysis. *For more details, please refer to the PDF materials or feel free to contact us.

• Gas recovery/treatment equipment

In the case of an evaporator, in addition to the evaporator body, a vacuum pump, a refrigerant circulation device, and, depending on the situation, a separate cool trap device are required, which takes up considerable space. Furthermore, it is difficult to perform a complete cleaning of the entire system, including the cooling section, every time, so it is often shared among multiple users, which can lead to contamination. The "Salt Mini" has a compact footprint of 14cm x 12cm. It allows for the direct concentration of solvents contained in sample bottles (available in two specifications: 20mL and 50mL). **Advantages of Salt Mini:** - No need to transfer containers like with an evaporator - Very fast distillation concentration possible with solvents having boiling points similar to hexane - Space-saving (footprint = 14cm x 12cm) - Fully automatic, so once the sample is set up, it can be left unattended - Solvent is collected in a nearly 100% recovery bottle (which is also a sample bottle) *For more details, please refer to the PDF document or feel free to contact us.*

• Gas recovery/treatment equipment

In the laboratory, exhaust gases generated from solvent purification tasks are typically released after capturing solvent vapors using cooling traps and the like. For example, in the case of solvent distillation recovery using a rotary evaporator, it is common to condense and capture the vapors in the cooling tube inside the evaporator, which serves as the primary cooling trap, and then discharge them directly outside the system. Our company proposes a system that combines a "cool trap" and a "Wulf bottle" in addition to standard solvent recovery equipment. By using these products appropriately, it is possible to reduce the solvent vapors (VOCs) in the exhaust gases from the organic solvent recovery system to nearly zero levels. 【Features of the Cool Trap】 - Designed to thoroughly remove solvent vapors from exhaust gases coming from the pump. - Achieves maximum effectiveness when used in conjunction with a Wulf bottle. *For more details, please refer to the PDF materials or feel free to contact us.

• Gas recovery/treatment equipment

Chemical reactions utilizing short-lived active species, starting with organometallic compounds, are often conducted at low temperatures below 0°C to improve reaction selectivity and increase the yield of target products. Typically, low-temperature environments are created using dry ice/acetone, dry ice/methanol, or liquid nitrogen, but accurately controlling the temperature can be quite challenging. The "UC Reactor" allows for precise temperature control in the range of -100°C to +50°C, with programmable control of the temperature profile. It enables the execution of highly reproducible experiments with good efficiency and accuracy. **Reasons why the ultra-low temperature reaction device "UC Reactor UCR-150N-S" is supported:** - No need for non-fluorinated refrigerants - Precise temperature control (programmable control) in the range of -100°C to +50°C - Custom design options for the shape of the aluminum block in the cooling chamber - Compact design that does not obstruct the laboratory bench - Maintenance-free *For more details, please refer to the PDF document or feel free to contact us.*

• Cooling system

We would like to introduce an example of using the "Ultra-Low Temperature Reaction Machine UC Reactor UCR-150N-S" that we handle as a cooling trap at -100℃. When drying samples in a vacuum dryer, it is common to use an electric cooler at around -20℃ before the vacuum pump. In cases where the solvent has a low boiling point, dry ice/acetone (-78℃) or liquid nitrogen (-196℃) may also be utilized. The ultra-low temperature trap using UCR combines the "UCR-150" with a dedicated aluminum block for cooling traps, allowing for safe and accurate cooling down to -100℃. The aluminum block can be manufactured to meet customer needs. 【Current Issues】 ■ Insufficient cooling temperature damaging the vacuum pump or releasing into the environment ■ The dry ice that was supposed to last overnight is completely gone by the next morning ■ The trap temperature rises, causing all the solvent that was carefully collected to evaporate again *For more details, please refer to the PDF document or feel free to contact us.

This book was first published in 1981. It is filled with fundamental information about electrochemical synthesis and is regarded as an essential resource for researchers in organic electrochemical synthesis as well as for research and development professionals aiming to achieve their goals using organic electrochemical synthesis. In recent years, organic electrochemical synthesis has gained renewed attention. However, since it is a method that is not very familiar to organic chemists who typically do not work with electricity, it can be considered a relatively high-barrier field. We hope that this re-publication will be of help to researchers and developers.

HFIP (hexafluoroisopropanol) is one of the few solvents capable of dissolving many crystalline polymers. In particular, it has become an indispensable solvent for measuring the molecular weight and molecular weight distribution of polymers using GPC (gel permeation chromatography). However, HFIP is an expensive solvent, with a price of about 100,000 yen per kilogram. Therefore, if HFIP can be reused after GPC measurements, research and development costs can be utilized more effectively. Our company offers HFIP purification services.
