What do you need to do after the glass reactor is installed? Do you know?

The experimental glass reactor is injected into a constant temperature cold source or a heat source through an oil bath to thermostatically cool or heat the reactants, and has a stirring function. The supporting device includes a vacuum pump, a low temperature coolant circulating pump, a circulating oil bath, etc., and is widely used in chemical industry. , biopharmaceuticals and new materials synthesis. In the previous section, we introduced the preparation of the experimental glass reactor before installation. Today we will talk about what else needs to be done after the installation of the experimental glass reactor.

Experimental glass reactor

First, after the reactor is installed, it is necessary to pass a certain amount of nitrogen for 30 minutes to check for leaks. If there is any leak, please use soap foam to find the leak point of the pipeline and nozzle, and find the leak point and then let the gas tighten. A nitrogen hold test is again applied to ensure that normal operation begins after no leakage.

When cooling and cooling, water can be cooled internally through the cooling coil. Please note that rapid cooling is prohibited to prevent excessive temperature difference stress from causing cracks on the cooling coil and the kettle body. At the same time, when the temperature in the kettle exceeds 100 °C, the water jacket between the magnetic stirrer and the kettle lid should pass through the cooling water to ensure that the water temperature is less than 35 °C to avoid demagnetization of the magnetic steel.

The safety device of Lanfan Glass Reactor adopts the positive arch type metal stainless steel rupture disc, which is manufactured according to GB567-89 "arching metal blasting technical conditions". It has been tested at the factory and cannot be adjusted at will. If it has been blasted and needs to be replaced again, it should be replaced in time for the blasting pressure exceeding the calibration blasting pressure. If it is used frequently, it should not exceed 80% of the lower limit pressure of the rupture disc. When replacing, it should be noted that the convex surface of the rupture disc should face upward.

After the reaction of the glass reactor for the experiment , the cooling and cooling should be carried out before the gas in the kettle is discharged to the outside through the pipeline to reduce the pressure in the kettle to normal pressure. Please take care to remove the pressure and loosen the main bolt nut symmetrically. Remove and then remove the lid from the holder. Pay special attention to protect the sealing surface during the entire removal process.

The sample in the glass reactor was cleaned. Each operation is completed with a washing solution (cleaning solution used should be taken to avoid corrosion of the host material) remove residue kettle body and the sealing surface, do not use hard or rough surface of the material to the article for cleaning reactor.
