Abstract

The invention relates to a laboratory organic solid purification device and a method based on a solid-liquid phase transition principle. The whole device is controlled by a singlechip. The device comprises a glass smelting furnace (1) and a heating part, wherein a diameter-variable raw material inlet is formed at the top of the glass smelting furnace (1); a heating ring moving rail (5) which controls a heating ring (2) to move and is parallel to the smelting furnace is arranged beside the glass smelting furnace (1); the heating ring (2) is positioned on the outer side of the glass smelting furnace (1) and fixed on the heating ring moving rail (5); a windshield (4) is arranged between the heating ring (2) and the heating ring moving rail (5); and the windshield (4) and the heating ring moving rail (5) are fixed on a base (3). The device and the method can be used for purifying laboratory organic solid with weight between 1g and 10g, a control system is simple and convenient, no waste liquid or waste gas is discharged and exhausted, a solvent is saved, and the manufacturing cost is low. The device and the method can be used for partially substituting column chromatography extensively used in a laboratory at present.

Description

[0001] technical field [0002] The invention relates to a laboratory organic solid purification device and method based on the principle of solid-liquid phase transition, which can reduce the cost of laboratory organic solid purification, have no waste liquid and waste gas discharge, save solvents, and save manpower, which is of great practical significance technological inventions. [0003] Background technique [0004] For organic small molecular solids, the laboratory generally adopts the method of column chromatography, which usually can only obtain a purity of no more than 98%. It is difficult to exceed 99%, and it is time-consuming and labor-intensive, and the cost is extremely high. Based on the principle of solid-liquid phase change purification, the present invention designs a regional smelting device suitable for laboratory organic solid purification, which can realize the purification of laboratory organic solids in the range of 1-10g. The entire inventive devi...
