    摘要: The present invention relates to a process for producing an MEK-modified resorcinol-formalin resin, in which recovery and reuse of the specific raw materials (water, calcium chloride, and methyl ethyl ketone (MEK)), and methanol contained in formalin, are carried out in parallel. Using this closed-system recycle production method, a resorcinol-formalin resin aqueous solution can be obtained, wherein the resin aqueous solution has a reaction product concentration of from 30 to 80%, moderate flowability with a pH of 6 to 10, a calcium chloride concentration of 100 ppm or less, a peak area corresponding to a resorcinol monomer of from 3 to 9% to the entire peak area obtained by gel permeation chromatography analysis, and a peak area corresponding to resorcinol pentanuclear or higher nuclear bodies of from 30 to 55% to the entire peak.

    摘要: A naphtha-soluble, hydrogenated C.sub.1-4 -alkyl C.sub.6-10 -aryl ketone/formaldehyde resin, having an oxygen content of at least 6% by weight and a softening point of at least 70.degree. C. can be produced by a process comprising the step of hydrogenating a C.sub.1-4 -alkyl C.sub.6-10 -aryl ketone/formaldehyde resin under a hydrogen pressure of at least 200 bar and a temperature of 140.degree.-300.degree. C., in the presence of a nickel, palladium, palladium/copper or palladium/nickel catalyst. These resins are useful, for example, as additives to improve the hardness of varnishes and other coatings.
