摘要: The invention relates to a method for producing a binder composition, without using a compound selected from the class of phenols. The method comprises: (i) heating an aqueous composition comprising lignin in the presence of a catalyst; (ii) mixing a crosslinking agent with the aqueous composition from (i) and heating the same at a temperature of 60-95° C. for pre-polymerizing lignin and crosslinking agent; (iii) mixing tannin with the aqueous composition from (ii) for polymerizing tannin with the pre-polymerized lignin and crosslinking agent until a binder composition with a predetermined viscosity value is formed; wherein the molar ratio of crosslinking agent to lignin and tannin is 0.5-1.7.

摘要: Modified lignin products, processes for making them, and their use to produce rigid polyurethane or polyisocyanurate foams are disclosed. The processes comprise heating a lignin source with a nitrogen source and a starved concentration of a C1-C5 aldehyde to give a reaction mixture comprising a Mannich condensation product, neutralizing the reaction mixture, and isolating the modified lignin product. The process is performed at a mass ratio of lignin source to nitrogen source within the range of 1:1 to 1:5 and at a molar ratio of nitrogen source to C1-C5 aldehyde within the range of 3.5:1 to 1:1. Polyol blends and performance additives that contain the modified lignin products are described. Rigid foams that process well and incorporate up to 60 wt. %, based on the amount of polyol component, of the modified lignin contribute to excellent flame retardancy and low-temperature R-value performance.

摘要: A method for the selective cleavage of a compound comprising an aromatic ring and a C—O—C linkage in the presence of a heterogeneous catalyst is provided. The heterogenous catalyst may be a supported noble metal catalyst doped with a halogen selected from the group consisting of chlorine and bromine. By using this method, it is possible to increase the selectivity and/or yield (preferably both) of aromatic compounds.

摘要: To provide a material that can be easily ascertained whether antibacterial or antiviral function is imparted. In the polyphenol derivative, hydrogen atoms of some hydroxy groups or some hydrogen atoms of aromatic rings of a polyphenol are substituted by a luminescent group. In the polyphenol derivative, hydrogen atoms of some hydroxy groups or some hydrogen atoms of aromatic rings of a polyphenol may be substituted by a chain hydrocarbon group. The polyphenol derivative may be network polymerized into a polymer material.

摘要: The present relates to a process for the depolymerization of lignin using chemicals recoverable by the soda or kraft mill recovery cycles. The process involves the use of sodium hydroxide or white liquor to depolymerize lignin in black liquor or other lignins (e.g. hydrolysis lignin, kraft lignin) by conducting the reaction at 170-250° C. for up to 3 hours in the presence or absence of a co-solvent and a capping agent. The depolymerized lignin is then obtained by acidifying the reaction products to a low pH to precipitate the de-polymerized lignin, followed by particle coagulation, cake filtration and washing with acid and water to obtain a purified depolymerized lignin product.
