Application of 2615-15-8, 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 2615-15-8, name is 3,6,9,12,15-Pentaoxaheptadecane-1,17-diol. This compound has unique chemical properties. The synthetic route is as follows.
Step 1: Preparation of 3,6,9,12,15-pentaoxaheptadecane-1,17-diol ditosylate A solution of 73.91 g of p-toluenesulfonyl chloride (0.389 mol) in 400 mL of methylene chloride is added dropwise with stirring over a 2.5 hrs period to 400 mL of methylene chloride containing 50 g of hexaethylene glycol (0.177 mol) and 64 mL of triethylamine (39.36 g, 0.389 mol) at 0 C. The mixture is stirred for one hr at 0 C. and heated to ambient temperature for 44 hrs. The mixture is filtered and the filtrate concentrated in vacuo. The resulting residue is suspended in 500 mL of ethyl acetate and filtered. The filtrate is concentrated in vacuo to a yellow oil which was triturated eight times with 250 mL portions of warm hexane to remove unreacted p-toluenesulfonyl chloride. The resulting oil is then concentrated under high vacuum to yield 108.12 g of a yellow oil (quantitative yield). Analysis: Calculated for C26 H38 O11 S2: Calc.=C, 52.87; H, 6.48. found: C, 52.56; H, 6.39. PMR (“proton magnetic resonance”): (60 MHz, CDCl3) delta: 2.45 (s, 6H); 3.43.-3.8 (m, 20H); 4.2 (m, 4H); 7.8 (AB quartet, J=8 Hz, 8H). IR (“infrared”): (neat) cm-1: 2870, 1610, 1360, 1185, 1105, 1020 930, 830, 785, 670.
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 2615-15-8, 3,6,9,12,15-Pentaoxaheptadecane-1,17-diol.
