Model: HH-5



Dimethyl malonate (DMM) is an important pharmaceutical intermediate, which is widely used in various organic synthesis reactions. At present, DMM production methods commonly used in industry mainly include cyanidation method and carbonylation method, but these two methods have their own problems that are difficult to overcome: cyanidation method has low yield, and the use of highly toxic sodium cyanide in production is easy to cause environmental pollution and personal injury; The carbonylation process requires the use of noble metal catalysts such as rhodium and palladium, which increases the cost, and the reaction conditions are harsh and dangerous.



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a gas chromatography method for the determination of industrial dimethyl malonate, a HH-5 capillary column method for the determination, and an area normalization method for the quantification. The results are satisfactory.
