With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.124-76-5, name is Isoborneol, molecular formula is C10H18O, molecular weight is 154.2493, as common compound, the synthetic route is as follows.Computed Properties of C10H18O
In this case, the reaction of preparing camphor by dehydrogenation of liquid isoborneol is carried out in a membrane reactor. In this case, the isoborneol is an industry grade raw material. Since at room temperature, the isoborneol is a solid powder, it is first dissolved in xylene to form 30% solution. The mass reaction space velocity of the solution is 0.5 h-1. After it goes through a heat exchanger to achieve preheating temperature of 220C, it goes into the membrane reactor for dehydrogenation. The pipeline is filled with the GC250 Cu-Zn-Al catalyst produced by Japan NGC Corporation and the thermocouple casing was used to measure the bed temperature of any one of the dehydrogenation reaction tubes. After the oxygen passes through the flow meter, it goes through the center tube dedicated to oxygen gas in the tube. Oxygen permeates through the membrane to the shell and reacts with hydrogen. The molar ratio of oxygen to isoborneol is 1: 6. The shell is filled with Pt / Al2O3 oxidation catalyst prepared by multiple coating-impregnation method, wherein the load mass fraction of Pt is about 1%; the pressure on the dehydrogenation side is 0.6MPa, the reaction temperature is 220C. The film used in the reactor is a silicon dioxide film system manufactured by Sulzer Chemtech (SMS). Each tube has an inner diameter of 8 mm and an outside diameter of 14 mm. The product of camphor and solvent xylene in the dehydrogenation side enters the solvent recovery section for solvent recovery and recycling, and the camphor product is sent to the finished product area.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,124-76-5, Isoborneol, and friends who are interested can also refer to it.
