T-Pentyl alcohol

Cognate preparation. 2-ChIoro-2-methylbutane. Use 22 g (27 ml, 0.25 mol) of 2-methylbutan-2-ol (t-pentyl alcohol) and 65 ml of concentrated hydrochloric acid. Distil the chloride twice from a Claisen flask with fractionating side-arm or through a short column. Collect the 2-chloro-2-methylbutane at 83-85 °C the yield is 18 g (68%). Record the p.m.r. spectrum (CC14, TMS) and assign the signals which appear at 51.01 (t, 3H), 1.51 (s, 6H) and 1.73 (q, 2H) note the overlap of the latter two signals. 

Cyclic non-conjugated (139 and 140) or conjugated (141 and 142) dienamines may be obtained by Birch reduction of the corresponding aromatic amine552,553. The preferred conditions involve the use of lithium and t-pentyl alcohol rather than ethanol, since the latter tends to give a considerably higher proportion of the further reduced tetrahydro derivative554. 

Because of the different rates of hydrogenolysis, aryl halides containing different halogens can be reduced selectively. 1 -Bromo-2-chlorobenzene is reduced to chlorobenzene in 96% yield on treatment for 2 h at room temperature with a complex reducing agent prepared from nickel(II) chloride, sodium hydride and t-pentyl alcohol. l-Bromo-4-chlorobenzene is converted to chlorobenzene on treatment with... 

Surface tension of hydrocarbon + alcohol mixtnres The surface tension of the binary hydrocarbon (benzene, toluene, cyclohexane, methyl-cyclohexane) + alcohol (ethanol, t-pentyl alcohol) mixtures were reported5 at 303.15 K (30°C).
