Polymers are currently in the limelight. Phenolic resin is one of polymer products obtained from polymerization process, either natural or synthetic sources. One compounds that can be applied to polymers cardanol. This study aimed synthesize cardanol-based acetaldehyde novolac Cashew Nut Shell Liquid (CNSL). Isolation cardanol CNSL was done by liquid-liquid extraction method with acetone and pu...

With a growing interest in hydrogen as energy carrier, the efficient purification of from gaseous mixtures is very important. This paper addresses separation using Carbon Molecular Sieves Membranes (CMSM), which show an attractive combination high permeability, selectivity and stability. Supported CMSM containing various amounts aluminium have been prepared novolac acetyl acetonate (Al(acac)3) ...

A bio-oil-based epoxy (BOE) resin was synthesized using phenolic compounds from beechwood pyrolysis oil. These were separated crude oil by coupling two methods: fractional condensation and water extraction. The chemical structure of the BOE characterized NMR FTIR analyses. used as a curing agent bio-oil glyoxal novolac (BOG) to gradually replace bisphenol diglycidyl ether (DGEBA). thermal prope...

On a global scale, methanol is one of the most important feedstocks and used widely as solvent co-solvent. However, due to polar nature associated ability conduct current, small molecule can take part in galvanic corrosion metal storage tanks degrade barrier properties protective coatings. In present work, we investigated degradation two novolac epoxy coatings polyurethane (PU) coating exposed ...
