Abstract:
Sulfonated cyclohexanone-formaldehyde resin (SCF) was synthesized using cyclohexanone and formaldehyde as raw materials, sodium sulfite as sulfonating agent. The composition of the SCF resin was characterized by FTIR and 13C NMR, and the possible mechanism for formation of the resin was suggested. The effects of reaction parameters, such as ratio of formaldehyde and cyclohexanone, the amount of sulfonating agent, as well as reaction temperature and pH, on the viscosity and average molecular weight were investigated. The results showed that the optimum reaction conditions was that the ratio of reactant was n(formaldehyde):n(cyclohexanone):n (sodium sulfite) = 2.0:1.0:0.7, and pH value of the system was 10 at 90°C temperature. The average molecular weight of the resulted resin was 58392. © (2013) Trans Tech Publications, Switzerland.
