摘要： Provided are a liquid hydrocarbon production method for obtaining a liquid hydrocarbon-containing rubber composition, including heating a crosslinked rubber at 300°C or lower in a reaction solvent that contains an aldehyde having a hydrocarbon group with 2 or more carbon atoms and having a boiling point of 230°C or lower; as well as a re-crosslinked rubber obtained from the rubber composition produced in the production method, and a tire and a rubber industrial product. According to the liquid hydrocarbon production method, a liquid hydrocarbon having a higher molecular weight can be produced at a high decomposition proportion even under mild conditions.

摘要： The present disclosure relates to a depolymerization method of a polymer comprising an ester functional group with or without pigments or dyes, a composition for the depolymerization, and a purification method for selectively separating foreign substances from a monomer of the polymer, and is characterized in that a compound represented by formula 1 is added as an additive. The depolymerization method according to the present disclosure enables depolymerization at low temperatures and may increase the yield of a target product. In addition, the purification method according to the present disclosure may remove foreign substances including pigments or dyes from a monomer of the polymer to prepare high-purity monomers.

摘要： This invention involves the recovery of high quality polyols from flexible polyurethane (PU) foam wastes using a two-phase glycolysis process by means of a novel catalyst based on naphthenic salts or mixtures of their components preferably selected from the group of alkaline and alkaline earth salts. The process for preparing a recyclate polyol comprises bringing a polyurethane foam in contact with a glycolyzing compound containing at least two hydroxyl groups, and let the foam and the glycolyzing compound react at high temperature in presence of the naphthenic catalyst. By means of the use of a large excess of a glycolysis agent, much larger than the estequiometric quantity, the reaction product splits in two phases, where the upper layer is mainly formed by the recovered polyol from the PU, and the bottom layer is formed by the excess of glycolysis agent. The upper phase can be purified by a liquid-liquid extraction using an aqueous phase and the excess of glycol of the bottom phase can be recycled to the process by vacuum distillation.
摘要翻译：本发明涉及使用基于环烷盐的新型催化剂或其组分的混合物使用两相糖酵解方法从柔性聚氨酯（PU）泡沫废物中回收高质量多元醇，优选选自碱金属和碱土金属盐。制备再循环多元醇的方法包括使聚氨酯泡沫与含有至少两个羟基的糖解化合物接触，并使泡沫和糖醇化合物在环烷催化剂存在下在高温下反应。通过使用大量过量的糖酵解剂，反应产物分成两个阶段，其中上层主要由回收的多元醇由PU形成，底层形成由过量的糖酵解剂。可以通过使用水相的液 - 液萃取来纯化上相，并且通过真空蒸馏将底部相的过量二醇循环到该方法中。

摘要： This invention relates to a single-component and multi-component catalytic systems using aryl titanates. Aryl titanate compounds are useful as catalysts and co-catalysts in single component and multi-component catalytic systems (e.g., for the polymerization of macrocyclic oligoesters and the depolymerization of polyesters). Multi-component catalytic systems using aryl titanites allow increased versalitity in applications such as liquid molding.

摘要： A process for preparing a recyclate polyol obtained from glycolysis of polyurethanes and/or polyurea-polyurethanes comprises reacting scrap polyurethane and/or polyurea-polyurethane with a short-chain compound containing at least 2 OH groups in the presence of a catalyst and admixing a cyclic carbonate. The process results in a recyclate polyol having a low primary aromatic amine content which may be used to produce cellular or non-cellular polyurethanes, polyurea-polyurethanes, or polyisocyanurates.
