Application of 23783-42-8, 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 23783-42-8, name is 2,5,8,11-Tetraoxatridecan-13-ol. This compound has unique chemical properties. The synthetic route is as follows.
To a solution of tetraethyleneglycol monomethyl ether (2) (10.0 g, 48.0 mmol) and pyridine (84 mL) in CH2Cl2 (170 mL), solid p-toluenesulfonyl chloride (22.0 g, 115.4 mmol) was added portion-wise at -20 C under nitrogen. The resulting reaction mixture was stirred for 2 days at -20 C. Then, the reaction mixture was allowed to warm to room temperature and water (200 mL) was added. The aqueous layer was extracted with CH2Cl2 (150 mL × 3). The combined organic fractions were dried over MgSO4 and the solvent was removed under reduced pressure. The crude product was purified by chromatography on silica (1:1 EtOAc:hexanes; Rf = 0.3) to yield 3 as a colorless oil, 16.4 g, 94%.1H NMR (500 MHz, CDCl3): delta = 7.80 (d, Ar, 2H), 7.34 (d, Ar, 2H), 4.16 (t, 2H), 3.66 (t, 2H), 3.62-3.65 (m, 6H), 3.58 (s, 4H), 3.532-3.56 (m, 2H), 3.34 (s, 3H), 2.43 (s, 3H). 13C NMR (125 MHz, CDCl3): delta = 144.71 (s, CSO2O), 132.94 (s, CH3CCH), 129.74 (s, CHCHCSO2), 127.89 (s, CCHCH), 71.79, 70.57, 70.46, 70.44, 70.38, 70.36, 69.20, 68.52, 58.94 (CH3OCH2), 21.56 (CH3CHCH). Data was consistent with a previously reported compound [5].
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 23783-42-8, 2,5,8,11-Tetraoxatridecan-13-ol.
