In this article, we largely decreased the reaction temperature for ultraviolet (UV) photochemical reduction of H 2 PtCl 6 solution to −60 °C and demonstrated such a method as a fast and convenient process for the synthesis of atomically dispersed Pt. We showed that the ultralow-temperature reaction efficiently inhibited the nucleation .
The CH 3 observation implies a kinetically sensitive test to the measured and estimated hydrocarbon rate constants at low temperatures. We identify the key reactions that control the concentrations of CH 3 in the model, such as the three-body recombination reaction, CH 3 + CH 3 + M --> C 2 H 6 + M, and the recycling reaction H + CH 3 + M --> CH .

High Pressure Ultrasonic Reactor System. TOPTION this type ultrasonic reactor is often used in laboratory extraction and chemistry reaction research, which has solve amplitude transformer and reactor sealing problems, could equip various types chemical reactors' accessories under high temperature, achieve reaction system gas separation and vapor phase condensation & reflux.
Tapered sides assure that the effective area of a 450w or 550w photochemical lamp can be entirely submersed into the liquid, contrary to traditional round bottom reaction flasks. Net result is approximately a 20% savings in reaction time. An additional advantage of this design is in the initial mixing of reactants.
The first light source made available with the UV-150 photochemical reactor was the medium pressure mercury lamp. This provides constant and precise UV output, with user selectable UV power between 75 W to 150 W – allowing dimmable operation without compromising lamp life or spectral output.
Low temperature open bath circulator (CB) It is used to cool or control reactor temperature to -50°C by circulating thermic fluid cooled toup to -75°C inside the jacket or internal coil. It consists of a bath, pump, compressor, condenser& level switch. Suitable for reactors up to 100 ltr volume. Heating Cooling open bath circulator (HCB)
