Reference of 597-31-9, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 597-31-9, name is 3-Hydroxy-2,2-dimethylpropanal. A new synthetic method of this compound is introduced below.
2) Synthesis of Hydroxypivalic Acid: Add 40 ml of water to a 500 ml three-necked flask, start stirring, add 85 g of hydroxypivalaldehyde and 0.85 g of phosphotungstic acid catalyst, and then start heating. When the temperature rises to 55 C, Adding 123g of hydrogen peroxide, and adding for 2 hours; the oxidizing liquid is dehydrated under reduced pressure, filtering after dehydration to obtain the catalyst, taking out and reusing, and cooling and crystallizing the filtrate to obtain hydroxypivalic acid solution. 3) Drying: Hydroxypivalic acid solution was filtered to obtain wet products, the use of vacuum dryer for drying, temperature control at 58 , vacuum control in 0.085MPa, the final product hydroxypivalic acid, product yield of 85%.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,597-31-9, 3-Hydroxy-2,2-dimethylpropanal, and friends who are interested can also refer to it.
