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. 4263-52-9, name is Sodium 2-bromoethanesulphonate, A new synthetic method of this compound is introduced below., HPLC of Formula: C2H4BrNaO3S
44.6 g of isophorone diisocyanate (IPDI) was added in a mechanically agitated round-bottom flask. 0.2 mL of catalyst dibutyltin dilaurate was added in the IPDI, and 17.8 g of dimethyl ethanolamine (HO CH2CH2N(CH3)2) was added dropwise in the IPDI while stirring at 30 C. using a dropping funnel to form a reaction mixture. The reaction mixture reacted for 1 hr, and then was stirred to react for 12 hrs at 30 C. 42.2 g of 2-bromoethyl sodium sulfonate which was dissolved in 400 mL of anhydrous tetrahydrofuran was added dropwise in the reaction mixture and reacted for 1 hr to yield a white precipitate. The white precipitate was centrifugalized several times to yield the isocyanate-terminated betaine compound.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
