して低フリーフェノール樹脂が得られる。In the present invention, the compound of phenol and aldehyde with y>1g refers to all compounds obtained by a normal polymerization reaction, that is, by polymerizing phenol and aldehyde in the presence of a catalyst. 72) Types include phenol, cresol, xylenol, resorcinol, etc.
Aldehydes include formaldehyde, benzaldehyde, and paraformaldehyde. In addition, the term "catalyst" refers to all catalysts for the 7-volatization reaction, such as hydrochloric acid, diluted acid, and sulfuric acid. The condensate of phenols and aldehydes thus obtained was first mixed under reduced pressure (400
- 600 Torr), 150-180°C, preferably 1
Heat to 60°C and dehydrate for 30 to 60 minutes. Then, the pressure is returned to normal pressure and the temperature is 150 to 180°C, preferably 160°C.
Wash with water for about 1 hour. Washing is done with the same amount of distilled water as the condensate. This step azeotropically removes water and unreacted phenol, as well as removing the remaining catalyst.
In this case, since the azeotropic point of water and 7xnol is about 90°C, it is sufficient to heat it above that temperature, but since it takes a long time, washing with water is carried out at 150-180°C. However, if the temperature exceeds 180°C, there is a risk of bumping. After this, under reduced pressure,
Heat to 40°C, preferably 210°C, and dehydrate for about 1 hour. The degree of pressure reduction is approximately 30 to 60 Torr. This process almost completely removes impurities. After this, it is taken out to obtain a low-free phenolic resin.
