Web1. 0.30g of 1,4-dimethoxybenzene and 0.5 mL of t-butyl alcohol and 1.0 mL of glacial acetic acid were placed in an 18×150 mm test tube. The test tube was swirled to dissolve the 1, 4-dimethoxybenzene and after that placed in an ice-water bath. 2. 2.0 mL of concentrated sulfuric acid was added to another test tube and put in the ice-water bath. 3.

WebIn a large reaction tube, dissolve 500 mg of p-dimethoxybenzene in 2 mL of glacial acetic acid. Add 1 mL of t-butyl alcohol and place the tube in an ice-bath. You may have to heat the vial of t-butyl alcohol in a hot water bath to aid in this transfer. In small aliquots, add 1.6 mL of concentrated sulfuric acid with stirring after each addition. WebThis experiment aims to produce 1, 4-Di-t-butyl-2,5-dimethoxybenzene by reacting itwith … WebThis substitution involves the reaction by the electrophilic tri- methylcarbcation. The end result is to produce 1,4 di-t-butyl-2,5-dimethoxybenzene by using TLC, IR spectroscopy, and vernier caliper for melting point. Figure 1.
