Description
Technical field
This utility model belongs to chemical separation and purification technical field, relate to a kind of three-dimensional Atmospheric vacuum solvent purification distilling apparatus, particularly relate to a kind of in Atmospheric vacuum situation, solvent purification with take easily, can dropping limit, limit purification solvent, three-dimensional Atmospheric vacuum solvent purification distilling apparatus that horizontal type and vertical still combine.
Background technology
Experiment of Organic Chemistry be unable to do without solvent, and solvent serves not only as reaction medium and uses, and also commonly used in the purification and post processing of product.Commercially available organic solvent has all sizes such as technical pure, chemical pure and analytical pure, and purity is higher, and price is more expensive.In organic synthesis, usually according to the feature of reaction and requirement, select the solvent of suitable specification, in order to enable reaction successfully to carry out and meet the principle of economy.Some organic reaction (such as Grignard reaction etc.), solvent requirement is higher, even if only having the existence of micro organic impurity and trace water, also reaction rate, productivity and purity can be brought certain impact.Owing to the amount using solvent in organic synthesis is all relatively larger, buy expensive commercial anhydrous solvent if only relying on, not only relatively costly, not easily preserve, sometimes also differ and meet the requirement of reaction surely.Therefore understand organic solvent character and purification process, be highly important.No matter considering from viewpoints such as safety, efficiency, energy-conservation and costs, the purification of organic solvent, being a basic operation of organic synthesis work, organic solvent purifying device is a ring indispensable in the middle of Modern Laboratory planning management, will be also following developing direction.
Conventional solvent purification device is generally formed (its structure is as shown in Figure 1) by heater, round-bottomed flask, liquid storage ball, stop,threeway, condensing tube and breather etc., it is vertical operating system, package unit extremely lower and upper placement, operation is also vertical carrying out, cannot from left to right place, carry out horizontal type operation.During solvent purification, desiccant suitable for solvent addition to be purified, deicer, cleaner or developer etc. are heated to reflux certain time, then solvent are steamed in liquid storage ball, taken out by liquid storage ball piston or needle tubing, thus obtaining anhydrous purification solvent.Traditional solvent purification device can only purification single solvent, cannot be carried out separating, multiple mixed solvent can not be processed with a set of purification devices, solvent purification simultaneously can only carry out when normal pressure, if needing oxygen free operation, it is possible to logical noble gas, but solvent purification cannot be carried out under the environment of decompression, more cannot be carried out dripping while solvent purification, the operation of the multiple mixed solvent of atmospheric and vacuum distillation purifies and separates.
Distillation belongs to thermodynamic (al) separating technology, is that the unit that a kind of mass transfer separates operates, is widely used in the fields such as oil refining, chemical industry, light industry.It utilizes each component boiling point in mixing liquid or liquid-solid system different, makes low boiling component evaporate, then condenses to separate the unit process of whole component, is evaporation and the associating of two kinds of unit operations of condensation.Distillation utilizes the difference of each component volatilization in liquid mixture and by the mass transport process of Component seperation, is separate boiling point to differ a kind of important operating technology of bigger mixture, and the separation especially for liquid mixture has important Practical significance.Generally, the boiling point of liquid mixture has to differ by very big (more than at least 30 DEG C) and just can obtain good separating effect.Separation means with other, compare such as absorption, extraction, filtering for crystallizing etc., its advantage is in that not need to use other component beyond system components, pass through distillation procedure, required product can be directly obtained, and absorb and extraction etc. also needs to such as other component, thus ensureing to introduce new impurity.
Distillation is divided into air-distillation and decompression distillation, the difference of each component volatilization degree in liquid mixture is utilized under normal pressure, make the vaporization of liquid mixture part and make vapor portion condense therewith, it is achieved the separation of component contained by it is called air-distillation (its structure is as shown in Figure 2 and Figure 3).The principle that boiling point according to liquid changes with the change of ambient pressure, by means of pressure in vacuum pump reduction system, makes the boiling point of liquid reduce and the distillation procedure that carries out is called decompression distillation (its structure is as shown in Figure 4).In distillation procedure, when some Organic substances are heated near boiling point, can aoxidize because temperature is too high, decompose or the reaction such as polymerization so that it is cannot distill at ambient pressure.If being connected on depressurized system by distilling apparatus, whole system pressure is made to be reduced to ten parts of only normal pressure to 1/tens before distillation starts, then this type organic just can distill at the temperature much lower compared with its normal boiling point.Atmospheric and vacuum distillation is the common method separating and purifying organic compound, and distillation of reducing pressure is particularly well-suited to those materials not reaching boiling point decomposes, oxidation or polymerization when air-distillation.
From existing distilling apparatus, no matter it is air-distillation, or decompression distillation, it being horizontal type operating system, package unit is from left to right placed, and operating process is that horizontal type carries out, it is impossible to lower and upper placement, carry out vertical operation；And existing solvent purification device and atmospheric and vacuum distillation unit all separate, all single use of each device, only possess unicity, it is impossible to multipurpose uses.Solvent purification is just for a kind of liquid handling, it is impossible to purification mixed solvent, it is impossible to carry out distillation procedure, also cannot purification at reduced pressure conditions, particularly can not process on dropping limit, limit, add novel solvent in time；And atmospheric and vacuum distillation unit separation of liquid mixtures, it is clear that solvent purification process can not be carried out.For reaching the purpose that solvent purification separates, have to arrange and overlap experimental provision more, cause the great wasting of resources, different device horizontal types is placed, need very big space arrangement, causing great space waste, finding the assay device that the solvent purification of a kind of solid and atmospheric and vacuum distillation combine is the huge reform to current unicity assay device.
