Sugar meter manufacturer: What is the process for dehydrating with isopropyl alcohol?

Blood glucose meter manufacturers: Every item has its own intrinsic value, and in our daily lives, there are countless essentials and products that we simply cannot do without. Similarly, in the industrial sector, a wide array of machinery and equipment plays vital roles across diverse fields. Isopropanol dehydration is no exception, and today we’re going to talk about it. Isopropanol dehydration Some basic information about the process, perhaps? If you’re interested, let’s keep reading.

Glucose meter manufacturer: Isopropyl alcohol dehydration in the process The liquid phase is a low-concentration isopropyl alcohol, which is obtained by distillation in a crude distillation column. 85%-87% an aqueous solution of isopropyl alcohol, which is then evaporated in a distillation column to 95% , then extracted with benzene to 99% The above. Propylene and water are each pressurized to 1.96MPa , preheat to 200℃ , mixed and added to the reactor, with a molar ratio of water to propylene of 0.7:1 , the single-pass conversion rate of propylene is 5.2% , the selectivity is 99% Compared with the propylene sulfonation process, this method does not use sulfuric acid, thereby avoiding equipment corrosion and featuring a simpler process flow; however, it suffers from a low single-pass conversion rate of propylene, an excessively large recycle stream of propylene, and requires the feed propylene to meet a specified purity level. 99.5% 。

Glucose meter manufacturer: Isopropyl alcohol dehydration in the process Propylene conversion rate 60%-70% , isopropyl alcohol selectivity 99% , after distillation, the purity of isopropylene can reach 99.9% Above, diisopropyl ether is produced as a byproduct. In addition, using molecular sieves to catalyze the hydration of propylene to produce isopropanol represents another promising process‑improvement approach. To overcome the drawbacks of the direct hydration of propylene, … 95% Propylene as the raw material, reaction temperature 240-270℃ , reaction pressure 14.7-19.6MPa , water and propylene glycol are in excess. Isopropanol dehydration in the process The reaction gas, after neutralization and heat exchange, is sent to a high-pressure cooler and a high-pressure separator. The isopropanol in the gas phase is recovered by spray‑stripping with deionized water in a recovery tower, where it undergoes hydration. The reactor is packed with a diatomaceous earth–phosphate catalyst, and the reaction temperature is… 95℃ , pressure 0.96MPa The unreacted gas is pressurized by the recirculation compressor and returned to the process for reuse.

Glucose meter manufacturer: Isopropyl alcohol dehydration in the process Alternatively, propylene and water may be pressurized separately to 1.96MPa , preheat to 200℃ , after mixing, the mixture is fed into a reactor for hydration. The mixture containing propylene 50% The above feed gas and 75% ~ 85% of concentrated sulfuric acid in 50℃ The absorption reaction is carried out under low pressure, producing bisulfuric acid. The bisulfuric acid is then hydrolyzed to yield isopropanol. Isopropanol dehydration in the process After crude distillation, it is further distilled in a distillation column to 95% Then extract with benzene, separate the water, and distill to obtain isopropyl alcohol. 99% The finished product above. Hydrogenation produces isopropanol. This method is in 2005 The post‑New Year price increase was primarily driven by an inverted price spread for isopropyl alcohol, as one of its traditional end uses is dehydrogenation.
