Adding some certain compound to certain chemical reactions, such as: 3973-18-0, name is Propynol ethoxylate, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 3973-18-0. 3973-18-0
A solution of 1.7 g of lib and 3 ml of triethyl amine in 20 ml of diethyl ether was treated at O0C with 1.5 ml of methanesulfonyl chloride. The mixture was stirred for an additional 30 min and then diluted with 35 ml of water and extracted with ethyl acetate. The combined organic layers were washed with IM aq. K2CO3 solution and water, dried and concentrated, to provide 2.45 of lie as a colorless oil; Rf 0.45 (heptane/ethyl acetate 1/1).NMR (CDCl3) delta 2.48 (t, 1, acetylene-H), 3.08 (s, 3, CH3SO2), 3,82 (m, 2, CH2), 4.03( d, 2, CH2), 4.41 (m, 2, CH2).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 3973-18-0.
