To Prepare Phenol Formaldehyde Resin Experiment Pdf. One classification of polymers divides them into thermoplastic and thermosetting resins. Dissolve phenol crystals in formaldehyde and acetic acid. Phenol and formaldehyde are reacted in the presence of an acidic catalyst, sulfuric acid. To determine ca++ and mg++ hardness of water using edta solution. Formaldehyde is a suspected carcinogen and should also be handled with gloves. The document describes an experiment to prepare phenol formaldehyde resin (bakelite). To determine alkalinity of given water sample. Place 3.0 ml of liquefied phenol and 10 ml of 37% (by weight) aqueous formaldehyde solution in a 25. The reaction of formaldehyde with phenol can lead to either a heat reactive resole or a stable novolak and is dependent upon the mode of catalysis. Procedures for phenol formaldehyde polymers novolac resin 1.
