Application of 2807-30-9, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 2807-30-9, name is 2-Propoxyethanol. This compound has unique chemical properties. The synthetic route is as follows.
Step 1: Synthesis of intermediate 3 a shown by formula (3 a); [Show Image] A four-necked reactor equipped with a condenser, a thermometer, and a dropping funnel was charged with 15 g (0.09 mol) of 5-formylsalicylic acid, 28.1 g (0.27 mol) of ethylene glycol monopropyl ether, 1.7 g (0.009 mol) of p-toluenesulfonic acid monohydrate, and 1000 ml of toluene under a nitrogen stream to prepare a homogenous solution. The solution was stirred for eight hours under reflux. Water produced during the reaction was removed together with toluene by azeotropic dehydration while adding toluene. After completion of the reaction, the reaction mixture was washed with water. After drying the toluene layer over anhydrous magnesium sulfate, magnesium sulfate was filtered off. Toluene was evaporated from the filtrate under reduced pressure to obtain a yellow oil. The yellow oil was purified by silica gel column chromatography (n-hexane:THF=3:1) to obtain 12.6 g of a light yellow solid intermediate 3a (yield: 55.5%). The structure of the intermediate 3a was identified by 1H-NMR. 1H-NMR (400 MHz, CDCl3, TMS, delta ppm): 11.34 (s, 1H), 9.89 (s, 1H), 8.42 (d, 1H, J=2.0 Hz), 8.01 (dd, 1H, J=2.0 Hz, J=8.6 Hz), 7.11 (d, 1H, J=8.6 Hz), 4.56 (t, 2H, J=4.6), 3.80 (t, 2H, J=4.6 Hz), 3.49 (t, 2H, J=6.6 Hz), 1.68-1.59 (m, 2H), 0.94 (t, 3H, J=7.6 Hz)
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 2807-30-9, 2-Propoxyethanol.
