4 Tempe rature ( C) The distillation of heat sensitive materials can be complicated; especially when the temperature at which distillation must be performed is high enough to cause thermal decomposition. Although the risk of thermal damage can be greatly reduced by distillation under vacuum, the duration of exposure to even moderate temperatures must also be considered. While, in most cases, the risk of thermal decomposition increases exponentially with temperature, it also increases linearly with the duration of thermal exposure. thermal decomposition no thermal decomposition Short path distillation addresses each of Pressure (mm Hg) these factors by permitting distillation at the lowest possible pressure with the shortest possible residence time. Unlike conventional "pot" distillation, the residence time of heat sensitive materials in short path distillation is limited to the time it takes the mixture being distilled to travel under force of gravity from the top to the bottom of the heated evaporator surface. Though this depends somewhat of the viscosity of the material being distilled, the residence time of heat sensitive materials in a KDL-4 short path distillation unit is generally less than 10 to 20 seconds. Distilling Heat Sensitive Materials As the material to be distilled (i.e., the feed stock) enters the evaporator of a KDL-4 short path distillation system, it is immediately distributed as a uniform thin film on the heated interior surface. As gravity draws the film downward, hot oil circulating through the surrounding jacket of the evaporator transfers enough heat to the thin film to cause more volatile components of the feed mixture to evaporate. Once liberated from the surface of the thin film in this way, the resulting vapors travel the short distance or "short path" to the internal condenser where they are returned to the liquid state and travel downward to be recovered as distillate. Meanwhile, remaining constituents of the film are agitated by three strands of rotating wiper rollers which serve to maintain film thickness and uniformity while aiding the diffusion of more volatile components to the surface of the film where their concentration has just been reduced by evaporation. All components of the mixture remaining in the film as it reaches the bottom of the heated evaporator surface are recovered as residue. At any given time, however, it is worth noting that only that portion of the original feed material comprising the thin film is and exposed to the temperature required to effect distillation. The rest of the feed material remains in the feed vessel. Also worth noting is the close proximity of the condenser to the heated evaporator surface. In more conventional wiped film or falling film distillation systems, limits to the pressure at which distillations can be performed are implicit in the pressure drop across the connection between the evaporator in which the concentration of vapors is high and the condenser in which the concentration of vapors is much lower. By locating the condenser internally, this pressure drop is minimized to the point where it can generally be disregarded. This, more than anything, is what makes KDL-4 short path distillation systems ideal for the distillation of heat sensitive materials at pressures as low as mbar. 1

14 The KDL and 825 Series of evaporators were designed to utilize an external heating mantle instead of a hot oil jacket. The benefits of the heating mantle are it can achieve a higher operating temperature than a hot oil circulator (hot oil circulators for Laboratory Model Evaporators are limited to a 400 C operating temperature) at a lower cost. The disadvantage of a heating mantle is that it does not provide the same level of temperature control which can be achieved using a hot oil heating media. This limitation in temperature control and heating consistency can result in a less selective distillation of the feed material. In other words, the Gaussian distribution of molecules in the distillate and residue products will have a higher standard deviation when using an electric heating mantle compared to a hot oil jacketed evaporator. However, if your budget is limited or your heating temperature requirements exceed 400 C, the heating mantle option may represent an opportune alternative. Chemtech will be happy to answer any of your questions related to heating options associated with our evaporators.
