Optimization of Synthesis Technology of Thermoplastic Phenolic Resin by Orthogonal Test |
| |
| Abstract: | Thermoplastic phenolic resin(Novolac)was synthesized from formaldehyde and phenol as raw material with oxalic acid as catalyst. Best synthesis conditions were found by orthogonal test. The optimum conditions were as followed: the amount of catalyst oxalic acid was 2.0%(based on phenol mass), the mo-lar ratio of formaldehyde:phenol=0.82:1, reaction time was 3.5 h. Variance result showed that the molar ratio of formaldehyde to phenol was the main affecting factor to the reaction. |
