    • The present invention provides a sulfonated coal tar distillate salt polymer that is a condensation product of an aldehyde, preferably formaldehyde, and a sulfonated middle fraction obtained during coal tar distillation. The middle fraction includes from about 40% to about 95% by weight naphthalene and from about 5% to about 60% by weight of a plurality of compounds selected from the group consisting of quinoline, indene, biphenyl, indane, acenaphtene, anthracene, phenanthrene, methyl naphthalene, cresol, phenol, xylenol, and tetralin. The present invention also provides a method of forming a sulfonated coal tar distillate salt polymer. The method includes sulfonating the middle fraction to form a middle fraction sulfonic acid mass, optionally adding a first portion of water to the middle fraction sulfonic acid mass to form a mixture, reacting the mixture and an aldehyde to form a condensate, optionally adding a second portion of water to dilute the condensate, and adding a base to form a sulfonated middle fraction salt polymer. Sulfonated middle fraction salt polymers formed in accordance with the method of the invention are useful as dispersants and plasticizers in aqueous cementitious slurries.

    • This invention is directed to a method of preparing a natural resin by liquefying wood, bark, forest residues, wood industry residues, or other biomass using rapid destructive distillation (fast pyrolysis). Fast pyrolysis produces both vapours and char from biomass, and following removal of the char from the product vapours, a liquid pitch product is recovered and processed by distillation, evaporation, or a combination thereof, in order to obtain a natural resin which may be in either liquid or solid form. The natural resin comprises a total phenolic content from about 30 % to about 80 % (w/w), and is a highly-reactive ligninic compound that has been found to be suitable for use within resin formulations without requiring any further extraction or fractionation procedures. Resins comprising up to 60 % natural resin have been prepared and tested in board production and found to exhibit similar properties associated with commercially available resins. The natural resin may substitute for phenol, or for both phenol and formaldehyde within phenol-containing resins. Similarly, the natural resin can replace a substantial part of the components within urea-containing resins.
    • 本发明涉及通过使用快速破坏性蒸馏(快速热解)液化木材,树皮,森林残留物,木材工业残余物或其它生物质来制备天然树脂的方法。 快速热解从生物质中产生蒸汽和焦炭,并且在从产物蒸气中除去焦炭之后,通过蒸馏,蒸发或其组合回收和处理液体沥青产物,以获得可以在 液体或固体形式。 天然树脂包括约30%至约80%(w / w)的总酚含量,并且是已被发现适用于树脂制剂中的高反应性木质素化合物,而不需要任何进一步的提取或分馏程序 。 包含高达60%天然树脂的树脂已经在板生产中制备和测试,发现与市售树脂相关的性能呈现出相似的性质。 天然树脂可以代替苯酚,也可以在酚醛树脂中代替苯酚和甲醛。 类似地,天然树脂可以代替含脲树脂中的大部分组分。
