Uses

1-Hexadecene is used as a surfactant in lubricating fluid, a drilling fluid in the boring and drilling industry, and in paper sizing.^[2] It is used to functionalize hydrogen-terminated silicon surfaces by hydrosilation.^[6]

However, the high reactivity of 1-hexadecene means that exposure to air could cause oxidation of its surface layer, forming unwanted impurities. It is stored with the use of tank blanketing, and handled in a dry, inert atmosphere.^[4]
