Description
Technical field
The utility model relates to field of chemical equipment, is specifically related to a kind of steam distillation device.
Background technology
Steam distillation is used to a kind of method of isolation andpurification liquid state or solid-state organic compound, is usually used in following several situation: the organic compound that (1) some boiling point is high, though distillation can be separated with byproduct at ambient pressure, is easily destroyed; (2) contain a large amount of resinous impurities or fixedness impurity in mixture, adopt the methods such as distillation, extraction to be all difficult to be separated; (3) isolate by the liquid adsorbed from more solid reactant.
General principle:
According to Dalton's law (of partial pressures), when the material not miscible with water and water coexist, the vapour pressure of whole system should be each Component vapor pressure sum, that is:
p＝pA+pB
Wherein p represents total vapour pressure, and pA is the vapour pressure of water, and pB is the vapour pressure of the not miscible material with water.
When in mixture, each Component vapor pressure summation equals external atmosphere pressure, temperature is at this moment their boiling point.This boiling point is all lower than the boiling point of each component.Therefore, apply steam distillation at ambient pressure, just can when high boiling component being steamed out together with water lower than when 100 DEG C.Because the relative quantity in total vapour pressure and mixture between the two has nothing to do, until wherein a component is almost removed completely, temperature just rises to the boiling point staying liquid in bottle.We know, in mixture steam, the ratio of each partial pressure (pA, pB) equals the ratio of their amount of substance (nA, nB), that is:
And nA=mA/MA; NB=mB/MB.Wherein mA, mB are the quality of each material steam in a constant volume, and MA, MB are the relative molecular mass of substance A and B.Therefore:
Visible, the relative mass of these two kinds of materials in distillate (be exactly them relative mass) in steam is directly proportional to their vapour pressure and relative molecular mass.
Existing steam distillation device is made up of steam evaporator, distillation fraction, condensation portion and receiver, in use have the following disadvantages: there is no safety measure, pipeline between steam evaporator and distillation fraction is long, and distillation fraction does not heat or Insulation.Steam just need can enter distillation fraction through very long conduit, and steam is condensation in the duct easily, and cause the steam heat entering distillation fraction not enough, test is made slow progress, and loses time.
