反応条件: temp:85.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 1140.0 g (10.0 mols) of trifluoroacetic acid was put in a four-way flask with a capacity of 5 liters and the reaction container was substituted by nitrogen, after which 315.0 g (2.25 mols) of hexamethylene tetramine was added at a temperature of approx. 30° C., and then 288.0 g of 4,4′-methylene bis(2-methyl-6-hydroxymethylphenol) (1.0 mol; purity 93% based on high-speed liquid chromatograph (HPLC)) was added under agitation over 3 hours at a temperature of 40° C. to cause reaction. After the entire amount of the material had been added, the temperature was raised to 85° C., and then the mixture was further agitated for 3 hours as a post-reaction. After the reaction, the obtained liquid was partially collected and hydrolyzed, and then analyzed based on HPLC. As a result, the main component that appeared to be the target substance had a composition ratio of 70%. Next, 800.0 g of water was added to the liquid obtained from the reaction to implement hydrolysis reaction for 1 hour at a temperature of 60° C. Crystal precipitated during this reaction. After the reaction, 1471.0 g of 16% aqueous sodium hydroxide solution was added to neutralize the obtained mixture liquid, and then 50 g of methyl isobutyl ketone and 50 g of methanol were added further, after which the mixture was cooled and precipitated crystal was filtered out to obtain 302.3 g of a composition. The obtained composition was put in a four-way flask with a capacity of 2 liters, and 369.2 g of methyl isobutyl ketone and 255.6 g of toluene were added, and then the mixture was maintained at a temperature of 70° C. and agitated for 30 minutes in a slurry state. The mixture was cooled and precipitated crystal was filtered out and dried to obtain 196.8 g of yellow powder crystal having a purity of 95.8% based on HPLC. The yield with respect to 4,4′-methylene bis(2-methyl-6-hydroxymethylphenol) was 69.3%. Based on the results of NMR and mass spectrometry, the obtained crystal was confirmed to be the target substance. reaction After the entire amount of the material had been added After the reaction the obtained liquid was partially collected Next, 800.0 g of water was added to the liquid obtained from the reaction hydrolysis reaction for 1 hour at a temperature of 60° C Crystal precipitated during this reaction After the reaction, 1471.0 g of 16% aqueous sodium hydroxide solution was added after which the mixture was cooled precipitated crystal was filtered out to obtain 302.3 g of a composition were added the mixture was maintained at a temperature of 70° C. agitated for 30 minutes in a slurry state The mixture was cooled precipitated crystal was filtered out dried
