Adding a certain compound to certain chemical reactions, such as: 4090-55-5, name is 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4090-55-5, Recommanded Product: 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide
In a reflux condenser, thermometer, stirrer,Constant pressure dropping funnel 2000mL four-necked flask was added74g cyclic phosphorus oxychloride,8g anhydrous aluminum trichloride and800mL chloroform,Under stirring to make it fully dissolved.Under stirring at 10 C,22.8g of cyclohexanediamine was added to a four-necked flask,To be added after completion of cyclohexanediamine, the temperature was raised to 50 , and at this temperature for 8h,After the reaction was completed, the solvent was recovered by distillation under reduced pressure, the residue was washed with deionized water three times,A white solid powder was obtained, which was dried at 60 C for 10 h to give 72.5 g of the product in a yield of 88.8% by weight.
