Abstract

L'invention concerne les procédés chimiques. Le procédé faisant l'objet de l'invention est du type comprenant le chauffage d'une acétone difurfurylidénique à humidité de 15 à 40 % à une température de 80 à 90 degrés C, avec réduction progressive de la pression de la valeur de la pression atmosphérique jusqu'à une valeur de 180 à 200 mm de Hg, avec addition subséquente d'un catalyseur à l'acétone difurfurylidénique et oligomérisation de cette dernière à une température élevée, et est caractérisé en ce qu'en qualité de catalyseurs on utilise des hydroxydes de métaux alcalins et/ou alcalino-terreux dans un rapport pondéral de l'acétone difurfurylidénique au catalyseur de 1 : 0,005 à 1 : 0,04, respectivement, et en ce que l'oligomérisation de l'acétone difurfurylidénique est conduite à une température de 180 à 200 degrés C. L'oligomère en question est utilisé notamment pour obtenir un liant pour les graphitoplastes employés dans la fabrication de paliers thermiquement et chimiquement stables, antifrictions et thermoconducteurs, d'anneaux de butée, de plaques de revêtement chimiquement stables.
