Abstract: The ALICE experiment at LHC is dedicated to study matter formed in heavy-ioncollisions, but also has a strong physics program for $pp$ collisions. In thesecollisions, protons will collide at energies never reached before underlaboratory conditions. At the high energies, ALICE will enable us to study jetphysics in detail, especially the production of multiple jet events, settingthe baseline for heavy-ion. Three-jet events allow us to examine the propertiesof quark and gluon jets, providing a suitable tool for testing QCDexperimentally. We discuss the selection method and topology of three-jetevents in ALICE. The analysis was performed on two PYTHIA data sets, bothinvolving $pp$ collisions at $\sqrt{s} = 14$ TeV with enhanced jet production.The results from the dedicated jet MC production are discussed and compared toprevious studies at CDF and D\O. We investigate the possibilities to determinegluon jet candidates.
