Abstract
Inventia se refera la un procedeu pentru obtinerea unei rasini cationice, anilinformaldehidice, utilizabila în industria de pielarie, ca produs de tabacire sau de umplere, conform caruia se efectueaza, în prima etapa, condensarea anilinei cu aldehida formica în proportie de 1...mol anilina la 0,6...0,8 mol aldehida formica, la temperatura de 80...120 degree C, timp de 4...6 h, în prezenta de 0,2...1% în greutate acid clorhidric concentrat, dupa care, în etapa a doua, rasina rezultata este supusa unei transpozitii termice, prin încalzire, la temperatura de 170...180 degree C, timp de 3...4 h, sub vid, în mediu de acid clorhidric.
