Abstract:
(EN) Disclosed is a method for efficiently producing a novolac resin having a low molecular weight, wherein a phenol and an aldehyde are reacted with each other under mild conditions. The method for producing a novolac resin is characterized in that a phenol and an aldehyde are reacted with each other in the presence of a catalyst that contains a boron compound represented by the following formula (I): B-(OR)3 (wherein R represents a hydrogen atom or an alkyl group having 1-10 carbon atoms) and an acid having a pKa of 5.0 or less.
(FR) La présente invention concerne un procédé permettant de préparer efficacement une résine novolaque de bas poids moléculaire, qui consiste à faire réagir un phénol et un aldéhyde dans des conditions douces, en présence d'un catalyseur qui contient un composé du bore représenté par la formule (I) B-(OR)3 dans laquelle R représente un atome d'hydrogène ou un groupe alkyle portant 1 à 10 atomes de carbone, et un acide ayant un pKa de 5,0 ou moins.
(JA)  フェノール類とアルデヒド類とを温和な条件下で反応させて、低分子量のノボラック樹脂を効率的に製造する方法であって、式(I) B-(OR)3 (I) (式中、Rは、水素原子、炭素数1~10のアルキル基を示す。)で表されるで表されるホウ素化合物およびpKaが5.0以下の酸を含む触媒の存在下、フェノール類とアルデヒド類とを反応させるノボラック樹脂の製造方法である。
