Abstract
The utility model relates to a continuous material dissolving and column chromatography recrystallization purification system, which is characterized by being mainly formed by sequentially connecting a material dissolving kettle (1), a material filling column (5) and a crystallization kettle (10) in series, wherein the top end of the material filling column (5) is even provided with a material filling column cover (7), a second jacket (6) is arranged outside the material filling column (5), a cyclic hot water inlet (8) and a cyclic hot water outlet (9) are respectively arranged on the second jacket (6), a third jacket (11) is arranged outside the crystallization kettle (10), a third steam inlet (13) and a low-temperature refrigerant inlet (14) are respectively arranged at the upper part of the third jacket (11), and the lower part of the third jacket (11) is provided with a third jacket medium outlet (15). The continuous material dissolving and column chromatography recrystallization purification system adopts the material filling column with jackets and a crystallization kettle system with heating and concentration solvents for being matched with the material dissolving kettle to be used, and the continuous and efficient refining on solid organic compounds in the fine chemical engineering production and the monomer liquid crystal preparation can be realized.
Description
Technical field
The utility model relates to a kind of continuous molten material, column chromatography recrystallization purifying system, and the continuous molten material, insulation column chromatography and the recrystallization that are mainly used in solid product in the preparation of fine chemistry industry production and monomer liquid crystal are purified.
Background technology
Column chromatography and recrystallization are the conventional means of purification refine SOLID ORGANIC compound.The customary filler post is that glass or lucite are made, and internal diameter is relative with length less, generally can't realize being incubated column chromatography, causes crystallization to separate out for solubility easily than miscellaneous goods, and separating effect reduces.Crystallization kettle generally links to each other with low temperature cryosel bath system, does not have heating concentrated solvent function, when column chromatography solvent for use amount is big, often causes the recrystallization effect relatively poor, and yield is on the low side.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and realizes in continuous high-efficient fine chemistry industry is produced and continuous molten material, column chromatography recrystallization purifying system that the SOLID ORGANIC compound in the monomer liquid crystal preparation is made with extra care.
The purpose of this utility model is achieved in that a kind of continuous molten material, column chromatography recrystallization purifying system, described system mainly is in series successively by molten material still, filled column and crystallization kettle, described filled column top even filled column post lid is arranged, described filled column is outside equipped with second chuck, is respectively arranged with the outlet of circulating hot water import and circulating hot water on described second chuck; Described crystallization kettle is outside equipped with the 3rd chuck, and described the 3rd chuck top is respectively arranged with the 3rd steam inlet and the import of low temperature refrigerant, and the bottom is provided with the 3rd chuck media outlet.
Be connected by stainless steel metal net corrugated flexible hose between described molten material still and the filled column.
Described filled column is the stainless steel helices post.
Operation principle of the present utility model is: molten material still links to each other with the stainless steel helices post by stainless steel metal net corrugated flexible hose, and second chuck of filler cornice insulation reaches the insulation purpose by circulating hot water.The 3rd chuck design of crystallization kettle has two conduit entrances, is respectively the 3rd steam inlet and low temperature refrigerant inlet.Solid chemical compound flows directly into the stainless steel helices post heat stirring and dissolving in molten material still after, in the stainless steel helices post, carry out flowing directly into crystallization kettle behind the chromatography, by the valve of opening the 3rd steam inlet crystallization kettle is heated concentrated solution, open the 3rd JO when a certain amount of and discharge hot water in the 3rd chuck when solvent is concentrated to, feed the dynamic crystallization that refrigerant carries out material by low temperature refrigerant inlet to the 3rd chuck this moment again.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts the filled column of strap clamp cover and possesses the crystallization kettle system of heating concentrated solvent, cooperates the use of molten material still, can realize that the SOLID ORGANIC compound to reaching in the monomer liquid crystal preparation in the fine chemistry industry production of continuous high-efficient is made with extra care.
