PEMANFAATAN CASHEW NUT SHELL LIQUID SEBAGAI SUMBER FENOL ALAMI PADA INDUSTRI

Use of cashew nut shell liquid as sources of phenol in industries. Cashew Nut Shell Liquid (CNSL) is a dark brown viscous liquid extracted from cashew nut shell. The main components of CNSL that is anacardic acid, cardanol and kardol which is a natural phenol compounds. Cardanol compounds have chemical structures similar to phenols synthetic, so the opportunity to substitute or replace the synthetic phenolic compounds from petroleum derivatives, whose the sources are running low. CNSL compound and its components anacardic acid, cardanol and kardol, and derivatives products have benefits that vary in different industries, as well as substitution of synthetic phenol as a so urce of phenolic compounds, such as the pharmaceutical industry, insecticides, adhesives, varnishes and paints, brake and clutch linings, laminating resin, epoxy resin, casting metal, cement, surfaktants, rubber formulations and various chemical industries. Until now, Indonesia's cashew nut shell not fully utilized, most still is a waste, so the production of CNSL in Indonesia is still very low. The potential for production of CNSL in Indonesia is actually quite large, therefore, given the various benefits of CNSL and its derivatives in various industries, as well as its superiority in the composition of the molecular structure and advantages as an environmentally friendly renewable material, then it's time CNSL potential contained in the ca shew nut shell can to productivity and well developed.
