    Abstract: A method of reclaiming trimethylolpropane from purification residue includes hydrolyzing a purification residue with an aqueous medium in the presence of (i) an acid and (ii) an oxidizing agent. The method is particularly effective to reclaim trimethylolpropane from monolinear-bis-TMP-formal: monolinear bis-TMP-formal (MBLF or TMP-BMLF); Formula II: [C2H5C(CH2OH)2CH2O]2CH2   (II)

    Abstract translation: 从纯化残渣中回收三羟甲基丙烷的方法包括在(i)酸和(ii)氧化剂存在下,用含水介质水解纯化残余物。 该方法特别有效地从单 - 双-TMP-正型:单萜双-TMP-正型(MBLF或TMP-BMLF)回收三羟甲基丙烷; 式II:[C 2 H 5 C(CH 2 OH)2 CH 2 O] 2 CH 2(II)

    Abstract: An improved method for deresination of wood chips or pulp is provided. The method comprises contacting the chips or pulp with an ethoxylated alkyl phenol deresinating composition during processing to reduce the level of natural resins present therein. The improvement comprises substituting a sufonated fatty acid for part of the ethoxylated alkyl phenol while maintaining substantially the same level of deresination.
