Trisphenol methane, its production method and its use |
abstract |
The present invention provides a trisphenol methane which is less colored, a method for producing the same, and a use thereof. When the phenol and the aromatic hydroxy aldehyde are reacted under heating under an acid catalyst, the reaction is carried out at a temperature of 100 ° C or lower from the first reaction to the reaction rate of 90%, and then the temperature is raised to more than 100. The trisphenol methane is produced at a temperature of ° C and at a temperature of 130 ° C or lower. Thereby, trisphenol methane having a Gardner color number of 9 or less (in a 0.5 mass% THF solution) and an epoxy resin having a small color can be obtained. |
