Synthetic Route of 26218-04-2, The chemical industry reduces the impact on the environment during synthesis 26218-04-2, name is 2-Ethylhexyl 4-aminobenzoate, I believe this compound will play a more active role in future production and life.
In a reactor, cyanuric chloride (18.4 g, 0.1 mole) is dissolved in 150 ml of acetone at 0 C.-5 C. Sodium bicarbonate (10.6 g, 0.1 mole) is added, then a solution of 2-ethylhexyl para-aminobenzoate (24.9 g, 0.1 mole) dissolved in 150 ml of acetone is added drop by drop at a temperature below 10 C. in 10 minutes. Next the heterogeneous mixture is left for 3 hours at laboratory temperature. 500 ml of water are poured in. The precipitate formed is filtered off, then washed with water. After drying under vacuum, 38 g of an off-white solid are obtained. After recrystallization of this solid from 1,2-dichloroethane, 25.2 g (yield 63%) of 2,4-dichloro-6-(2-ethylhexyl 4′-aminobenzoate)-s-triazine are obtained in the form of a white powder: UV (Ethanol/DMSO): lambdamax=291 nm, E1%=732, and used as such in the following stage.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Ethylhexyl 4-aminobenzoate, other downstream synthetic routes, hurry up and to see.
