Phenolic resin production
WebPhenolic-resin products are of two types: novolac and resole. Novolac is produced under acidic condition with excess of phenol, while resole is produced under basic condition also with excess of formaldehyde (Bilmeyer, 2005). Phenolic-resin synthesis is a complex process which is associated with loss of water; hence it is called http://www.iosrjen.org/Papers/vol8_issue9/Version-5/C0809051425.pdf
