In this reaction, t-butyl carbocation is generated via dehydration of protonated alcohol. 5) The Friedel-Crafts alkylation is a reversible reaction unlike acylation.

WebSummary. Infrared (IR) spectra for 1,4-di-tert-Butyl-2,5-dimethoxybenzene have been precisely estimated based on quantum chemical calculations and available for purchase. The IR spectrum table and chart are provided via a web-based graphical user interface (GUI). The table lists the vibrational frequencies and IR intensities. WebThe impurities caused a melting point depression because the impurity disrupts the crystal lattice energies. The limiting reagent was the 1,4 dimethoxybenzene which had 0 moles compared to 0 moles of t-butanol. Conclusion : The goal of the experiment was obtained because the product was in fact 1,4-di-t-butyl-2-5-dimethoxybenzene.

WebThe purpose of this experiment is to synthesize 1, 4-Di-t-butyl-2, 5 – dimethoxybenzene via the Friedel-Crafts alkylation mechanism by reacting 1, 4 – dimethoxybenzene with tertiary-butyl alcohol in the presence of sulfuric acid as a Lewis acid catalyst, and involves the attack of the aryl group at the electrophilic trimethylcarbocation.
