Documented Uses

• Used to make flavors, perfumes, pharmaceuticals, dyes, oils, and resins; [HSDB]
• Used in the organic synthesis of flavors, perfumes, pharmaceuticals, dyes, oils, and resins /1-Decene/
• The One-Step Ziegler Process involves the oligomerization of ethylene in the presence of trialkylaluminum at 180-220 °C and 140 atm.
• The Two-Step Ziegler Process involves the oligomerization of ethylene in the presence of aluminum alkyls at 175-200 °C and 136-204 atm. Chain growth continues with the reaction of light olefins with the aluminum alkyls continuously fed in stoichiometric amounts.
