Keywords:
Cardanol, Cashew Nut Shell Liquid,, Extraction,Abstract
ndia is the largest producer and processor of cashews (Anacardic occidental L) . Cashew nut shell liquid (CNSL) is a by-product from cashew nut processing. CNSL is a dark brown viscous liquid present inside a soft honey comb structure of the cashew nut shell. It contains phenolic compounds, mainly cardanol. Cardanol is a monohydroxyl phenol with a long carbon chain in the metaposition. It has the potential as a substitute for phenol in resin phenolic-base chemical products. The present review discusses various application of CNSL as well as the applications of constituents of CNSL. Various methods of extraction of CNSL are available in the literature. This review highlights various methods of extraction of CNSL and isolation of major constituents. The quantitative and qualitative analysis of CNSL is also pr esented in this review. Scope for future work is also discussed.Downloads
