Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, be an embodiment of a kind of flask of the utility model, comprise flask main body and four flask mouths, this device can be used as the flask of solid-liquid liquid three-phase reaction system; Flask main body is the Split type structure of top body 1 and bottom body 2, can open between top body 1 and bottom body 2, and after convenient reaction, solid sticky material takes out, simultaneously, the flask main body of Split type structure, makes more easily to clean in flask, offers convenience to the use of flask, improve the purity of product, if when top body 1 or bottom body 2 have a damage to need to change, only need change broken parts, another part do not damaged can continue to use, save material, save cost; Top body 1 lower openings, top is communicated with four flask mouths; Bottom body 2 upper opening, bottom is planar shaped, and bottom is planar shaped, can make placement that flask is firm on the table, not easily rock, and not easily tilts to break into pieces; Top body 1 and bottom body 2 is connected by connection gasket 10, easy disassembly, connects tight, and reactant is more or water-tight when pouring out reactant; Four flask mouths comprise the first flask mouth 3 being provided with the first filter membrane 7, for the second flask mouth 4 of conventional bottleneck, be provided with the 3rd flask mouth 5 of glass tube 9, be provided with the 4th flask mouth 6 of the second filter membrane 8, four flask mouths have different effects respectively, being provided with filter membrane in first flask mouth 3 and the 4th flask mouth 6, can, by filtering pouring liquids, preventing solid from separating out; Second flask mouth 4 is conventional bottleneck, can connect return duct in reaction; 3rd flask mouth 5 is provided with built-in glass tube 9, adds liquid for course of reaction, facilitates liquid to add, and prevents liquid residue at body, does not enter reactant liquor system, affects reaction effect.

Top body 1 and bottom body 2 are respectively hemispherical, facilitate reactant fully to contact.

Flask mouth is transversely arranged successively by the first flask mouth 3, second flask mouth 4, the 3rd flask mouth 5, the 4th flask mouth 6 order, pouring liquid time easy to use, the simultaneously convenient purposes distinguishing flask mouth.

First filter membrane 7 and the second filter membrane 8 are embedded in the middle part of flask mouth respectively, if filter membrane easily damages on top, can protect filter membrane at middle part, easy to use, facilitate pouring out of product, can check in time simultaneously and find that whether filter membrane is damaged.

First filter membrane 7 is the filter membrane that can filter organic phase, and the organic phase after reaction terminates, can be poured out by the filtration of filter membrane, prevent solid to be mixed into, and ensures the purity of product.

Second filter membrane 8 is the filter membrane that can filter aqueous phase, and the aqueous phase after reaction terminates, can be poured out by the filtration of filter membrane, prevent solid to be mixed into, and ensures the purity of product.

Connection gasket 10 is that upper and lower is all provided with the groove matched with flask walls thickness, and groove and the upper and lower part body of connection gasket 10 closely interlock, easy to connect, and dismounting is simple, and closure is good, prevents liquid from oozing out.

Connection gasket 10 is exotic material, may produce large calorimetric during reactant reaction, prevents connection gasket 10 heat damage to be out of shape.

Glass tube 9 is upper coarse and lower fine, glass tube 9 is deep in the body of bottom, it is convenient that upper coarse and lower fine structure makes liquid add, ensure that liquid can all flow in reactant simultaneously, fully contact with reactant, glass tube 9 length is slightly long, is also to ensure that the liquid added can fully contact with the reactant in the body of bottom completely, being unlikely to splash in flask walls.

Second flask mouth 4, higher than other flask mouths, facilitates adding of reactant, facilitates liquid to pour out, and facilitates simultaneously and is connected with return duct.

This flask is not only applicable to solid-liquid liquid three-phase reaction system, goes for equally in two phase reaction, of many uses, and one bottle multiplex, cost-saving, and result of use is good.

Use procedure:

In operation process, reactant and rotor is added in bottom body 2, then by sealing gasket 10, top body 1 is installed, put into magnetic agitation heating jacket, second flask mouth 4 of conventional flask mouth connects reflux, open magnetic agitation heating jacket, liquid is dripped by the built-in glass tube 9 in the 3rd flask mouth 5 in course of reaction, after remove and drip the device of liquid, add thermal response backflow terminate after, after room temperature is down in reaction, remove reflux, take off flask and pour out organic phase by the first flask mouth 3, aqueous phase is poured out by the 4th flask mouth 6, then upper and lower body is opened, take out solid, finally top body 1 and bottom body 2 are cleaned.

Adopt after technique scheme, the reaction of solid-liquid liquid three-phase reaction system can be made efficiently to carry out smoothly, by four different flask mouths, effects different in experiment can be completed, by arranging filter membrane at flask mouth, after the completion of reaction, different liquid can be poured out, solid is made to stay in flask, improve the purity of product, by flask is arranged to upper and lower Split type structure, easy solid residue takes out, reactant is facilitated to add, simultaneously convenient cleaning flask.
