The invention provides polyester polyol compositions and resin blends, useful as components of polyurethane and polyisocyanurate polymers, produced from cyclohexane oxidation reaction byproducts, such as water extracts and non-volatile distillation residues from the reaction. Such byproducts of industrial processes for preparation of adipic acid and caprolactam, important intermediates in the production of various types of nylon, have hitherto largely been used only as fuels. The present invention provides value-added products, methods for making, and methods for using the byproduct-derived polyester polyol compositions. For example, the invention provides polyurethane (PU) and/or polyisocyanurate (PIR) polymers made using the polyol compositions and polyfunctional isocyanates. The PU and PIR polymers can be used as adhesives, binders (e.g., for wood fibers), coatings (e.g., for controlled release fertilizers), and foams.
摘要:
The present invention is directed generally to a method of production of value-added, biobased chemicals from lignin sources, including waste lignin. A method of using a depolymerization of lignin to create a tiered production of biobased aromatic chemicals and biofuels is also described herein. The method described herein may also allow for the selective production of the biobased aromatic chemicals and biofuels. Additionally, a reduction of waste products may also be provided from the present method.

The present invention relates to a non-aqueous electrolyte additive for improving safety and a lithium secondary battery comprising the same, and more particularly to a non-aqueous electrolyte additive that can improve cycle life and safety properties of a lithium ion secondary battery. According to the present invention, an organometallic compound represented by the Chemical Formula 1 is added to a non-aqueous electrolyte of a battery as an additive, and thus if a battery voltage is out of normal operation voltage range due to a short circuit and overcharge of a battery, etc., the non-aqueous electrolyte additive decomposes and a part of the decomposed additive polymerizes to form an insulating film on a cathode surface, and a part of the metal reacts with an insulating film formed on a cathode surface to improve thermal stability of the battery, thereby improving safety of the battery.

A fragrance composition containing 0.0005 to 10% by mass of a decalin alcohol as component (a) represented by formula (1a) and 90 to 99.9995% by mass of one or more polycyclic woody-amber fragrances as component (b) selected from the group consisting of 7-acetyl-1,2,3,4,5,6,7,8-octahydro-1,1,6,7-tetramethylnaphthalene, 1,2,3,4,4a,5,6,7-octahydro-2,5,5-trimethyl-2-naphthalenol, 1,2,3,4,4a,7,8,8a-octahydro-2,4a,5,8a-tetramethyl-1-naphthyl formate, 3a-ethyldodecahydro-6,6,9a-trimethylnaphtho[2,1-b]furan, and racemic or optically active dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan; and a cosmetic product, a household product and an environmental/sanitary product containing the fragrance composition. The fragrance composition of the present invention is a highly versatile fragrance composition that brings about an odor of natural ambergris and can attain effects to enhance warmth and an odor quality even in a small amount.
摘要:
Process for the preparation of an alkynol with formula HC≡C—CH(OH)—R2(formula 2) wherein R2 represents methyl, halomethyl or ethyl, wherein the corresponding silyl-protected alkynol ester with formula 1 wherein R1 represents H, or an optionally substituted alkyl, an optionally substituted alkenyl or an optionally substituted (hetero)aryl group, R2 is as defined above and A3Si represents a trisubstituted silyl group wherein each A independently represents an optionally substituted alkyl or an optionally substituted (hetero)aryl group, in the presence of water and at least an equivalent amount of amine functionalities is converted into the alkynol with formula 2. Preferably, the amount of water is between 0.5 and 3 equivalents calculated with respect to the amount of silyl-protected alkynol ester with formula (1).
