'''加氫脫烷基反應'''是一種牽扯到[[芳香族]]的反應,例如[[甲苯]], 在有[[hydrogen]]的環境下會形成一個沒有[[官能基團]]的芳香族烴.[[1,2,4-trimethylbenzene]]轉換成[[xylene]]就是一個例子.<ref name="FP">[http://www.freepatentsonline.com/6509289.html Free Patents Online]</ref> 這一個化學過程通常發生在高溫高壓的環境之下,或是有[[催化劑]]的存在下進行。這些主要是[[過渡金屬]],例如:[[鉻]]或[[鉬]]。
'''Hydrodealkylation''' is a chemical reaction that often involves reacting an [[aromatic hydrocarbon]], such as [[toluene]], in the presence of [[hydrogen]] gas to form a simpler aromatic hydrocarbon devoid of [[functional group]]s. An example is the conversion of [[1,2,4-trimethylbenzene]] to [[xylene]].<ref name="FP">[http://www.freepatentsonline.com/6509289.html Free Patents Online]</ref> This chemical process usually occurs at high temperature, at high pressure, or in the presence of a [[catalyst]]. These are predominantly [[transition metal]]s, such as [[chromium]] or [[molybdenum]].
