    • The invention relates to a process for the preparation of resols by reacting phenolic compounds with aldehydes with catalysis by metal salts whose cation can easily be precipitated as low-solubility salts in industrial processes. In this process, a dispersant is added to the reaction mixture comprising phenolic compound, aldehyde and metal salt before, during or after the condensation reaction, and a complexing agent is admixed after the condensation reaction is complete and after the dispersant has been admixed. The resultant resins are transparent even after neutralization using sulphuric acid.
    • 本发明涉及一种通过酚类化合物与醛反应制备甲阶酚醛树脂的方法,其催化作用是通过金属盐进行催化,其阳离子可以容易地在工业过程中作为低溶解度盐沉淀。 在该方法中,在缩合反应之前,期间或之后,向包括酚类化合物,醛和金属盐的反应混合物中加入分散剂,并且在缩合反应完成后和分散剂混合后混合络合剂。 所得树脂即使在使用硫酸中和后也是透明的。
