Electric Literature of 111-90-0, 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 111-90-0, name is Diethylene Glycol Monoethyl Ether. This compound has unique chemical properties. The synthetic route is as follows.
59-1) Synthesis of 2-(2-ethoxyethoxy)ethyl 4-methylbenzenesulfonate 432 mg (3.22 mmol) of 2-(2-ethoxyethoxy)ethanol was dissolved in 40 ml of dichloromethane, and 0.6 ml (4.19 mmol) of triethylamine and 614 mg (3.22 mmol) of p-toluenesulfonyl chloride were added thereto. The mixture was stirred at room temperature for 15 hours. After the solvent was removed under reduced pressure, 40 ml of water was added thereto. The mixture was extracted with 30 ml of ethyl acetate. The solvent was removed under reduced pressure to give 760 mg (2.64 mmol) of the title compound in a yield of 82%. 1H NMR (CDCl3, ppm): delta 1.20(3H, t), 2.35(3H, s), 3.35(2H, q), 3.52(2H, t), 3.57-3.60(4H, m), 4.08(2H, t), 7.33(2H, d), 7.78(2H, d) FAB MS(m/e)=289 [M+1]
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 111-90-0, Diethylene Glycol Monoethyl Ether.
