Simple and easy organic chemical synthesis operation system

Abstract

The invention relates to a simple and easy organic chemical synthesis operation system. The system is characterized in that a set of van type whole device which consists of an outer frame, an air inlet, a first valve, a pressure gauge, a first valve, a pipeline, a second valve, a drying column, a deoxidization column, a thermal couple, a temperature controller, a power indicator lamp and an air outlet. The system has the advantages that an overall design of a stainless steel shell is adopted, so that the device is safer, and the van size is small so that the flexible movement can be ensured; 2, by adopting the drying column and the deoxidization column made of the stainless steel materials, the danger of fragile and flammable drying and deoxidization columns of conventional glass can be effectively avoided; 3, by adopting the internally-arranged thermal couple and the temperature controller device, the temperature for activation and regeneration of the dehydrated and deoxidization columns can be accurately controlled; because valves are arranged on many parts of the pipeline, and by controlling valve switches, columns are activated directly under a condition of not dismounting.

Description

technical field [0001] The invention belongs to the field of organic chemical synthesis, in particular to a simple organic chemical synthesis operating system. Background technique [0002] At present, the dewatering and deoxidizing devices used in domestic scientific research laboratories are scattered in structure, with many connecting pipes, complicated installation, easy damage and leakage points, and inconvenient regeneration and activation. These shortcomings greatly limit the application of anhydrous and oxygen-free operation in undergraduate teaching. [0003] The vacuum and inert gas switching device is an important operating system in chemical experiments, especially in organic synthesis experiments. It is mainly used for anhydrous and oxygen-free reactions of sensitive compounds. At present, the water-free and oxygen-free operating system devices in domestic scientific research laboratories mainly include five components: drying column, deoxidizing column, mercur...

AI Technical Summary

Problems solved by technology

The shell of the mercury manometer is also made of glass. When the gas pressure in the pipeline is too high during use, it is easy to cause mercury to rush out and cause harm to the operator.

Before using Schlenk to operate, it is necessary to manually install and connect the drying column, deoxygenation column, mercury pressure gauge, double-row pipe and vacuum pump, resulting in the scattered structure of the whole system and numerous connecting pipelines, which is not only cumbersome to install, but also easy to damage and form gas Leakage point; and after a period of use, the deoxidation drying column needs to be regenerated and activated. At this time, the deoxygenation drying column must be disassembled and activated separately. After activation, it can be used after installation, which causes a lot of inconvenience

Due to the above shortcomings, the vacuum and inert gas switching device and the anhydrous and oxygen-free operation are not only troublesome to use in scientific research laboratories, but also encounter obstacles when introduced from scientific research laboratories to undergraduate experimental teaching.
