  Preparation of Phosphate and Pyrophosphate Esters by the Metal-catalyzed Reaction of 8-Quinolyl Phosphates

  摘要：

  在 Cu (II) 离子存在下，烷基 8-喹啉基氢磷酸酯（烷基=乙基、环己基和苄基）在无水吡啶中转化为相应的 P1、P2-二取代焦磷酸盐，并形成 8-羟基喹啉-Cu (II) 螯合物。当该反应在含有醇（R'=乙基、戊基、环己基和苄基）的吡啶中进行时，相应的二烷基氢磷酸盐（R-R'=乙基-环己基、戊基-环己基、环己基-苄基和乙基-苄基）作为唯一产物生成。研究了影响这种金属催化反应的因素（含水量、溶剂、金属离子），并提出了反应的可能机理。

  This invention is related to a process for preparing polyester polymers using a composite catalyst comprises the steps of 1) esterifying naphthalene dicarboxylic acid or a dicarboxylic acids containing NDCA or ester derivatives thereof, with ethylene glycol or glycols containing ethylene glycol or derivatives thereof to produce esterified compounds or its low molecular weight polymers; and then 2) continuously polycondensing the obtained esterification product to produce polyester polymers; and wherein the process includes using a composite polymerization catalyst which was prepared by reacting titanium compounds and cobalt compounds in the solution containing at least one alcohol. The process yields high quality polyester polymers having a good color and excellent physical properties. The process can considerably reduce both the esterification time and the polycondensation time.

  本发明涉及一种使用复合催化剂制备聚酯聚合物的工艺，包括以下步骤：1）将萘二羧酸或含有 NDCA 的二羧酸或其酯类衍生物与乙二醇或含有乙二醇的乙二醇或其衍生物酯化，生成酯化化合物或其低分子量聚合物；然后 2）将获得的酯化产物连续缩聚，生成聚酯聚合物；其中该工艺包括使用复合聚合催化剂，该催化剂是通过钛化合物和钴化合物在含有至少一种醇的溶液中反应制备的。该工艺可制备出具有良好色泽和优异物理性能的高品质聚酯聚合物。该工艺可大大缩短酯化时间和缩聚时间。

  Provided are a molecular weight controllable, high 1,4-trans polybutadiene catalyst system, and more particularly, a four-component catalyst for preparing 1,4-trans polybutadiene with high yield, the catalyst comprising a cobalt compound, an organoaluminum compound, a phenol-based compound, and a phosphorus-based compound used to prepare 1,4-trans polybutadiene by polymerizing butadiene or a butadiene derivative, and capable of controlling the molecular weight of 1,4-trans polybutadiene by regulating the amount of the phosphorus-based compound. In particular, 1,4-trans polybutadiene may be efficiently applied to tires, belts, or the like since it has excellent tensile strength, tear strength, and cut & chip properties with increasing processability.
