The title compound, C(18)H(30)O(2), was prepared by Friedel-Crafts alkyl-ation of 1,4-dimeth-oxy-benzene with 2-methyl-2-butanol. The complete mol-ecule is generated by the application of a crystallographic centre of inversion. The two meth-oxy groups are oriented in the same plane of the aromatic ring [C-C-O-C torsion angle = 9.14 (16)°]. While one methyl group of the tert-pentyl substituent is coplanar with the benzene ring [C-C-C-C = 0.45 (15)°] and lies towards the less-hindered H atom, the other methyl and ethyl groups are directed to either side of the benzene ring [C-C-C-C torsion angles = 118.78 (12) and 59.11 (14)°, respectively]. In the crystal, the hydro-phobic mol-ecules pack to form a brick-wall-like architecture.
标题化合物C(18)H(30)O(2)是通过1,4-二甲氧基苯与2-甲基-2-丁醇的傅克烷基化反应制备的。整个分子由一个晶体学倒转中心生成。两个甲氧基位于芳香环的同一平面内[C-C-O-C扭转角 = 9.14 (16)°]。叔戊基取代基的一个甲基与苯环共面[C-C-C-C = 0.45 (15)°]，且朝向位阻较小的氢原子，而另一个甲基和乙基则指向苯环的两侧[C-C-C-C扭转角分别为118.78 (12)°和59.11 (14)°]。在晶体中，疏水分子堆积形成类似砖墙的结构。
