摘要:末端超氧铜 (II) 配合物在转化为过氧桥联二铜 (II) 配合物方面的不稳定性在很大程度上限制了他们在极低温度下的研究.这限制了它们氧化底物的动力学能力.作为回应,我们开发了一系列庞大的配体 Ar 3-Tmpa (Ar = Tpb,Dpb,Dtbpb),并使用它们来支持与 O 2反应反应生成[cu Ii (η 1-O 2 •-)(Ar 3-Tmpa)] +物质,在所有温度下对二聚化都是稳定的.o 2的结合在低于环境温度时饱和,并且可以通过变暖来逆转.ar = Tpb 和 Dpb 系统在 25 oc 时开始氧化,所有三种 [cu Ii (η 1-O 2 •-)(Ar 3-Tmpa)] +配合物在温度<=−20 oc.这为研究这些配合物提供了一个较宽的温度窗口,通过使用广泛的 O-H对 [cu Ii (η 1-O 2 •-)(Tpb 3-Tmpa)] +进行广泛的反应动力学测量来利用这一点,N-H

摘要:AIR OXIDATION OF ALKYL-SUBSTITUTED HYDROQUINONES IN THE PRESENCE OF HEAVY METAL SALTS AS CATALYSTS IN A LIQUID MIXED PHASE CONSISTING OF AN AQUEOUS PHASE AND AN ORGANIC PHASE. THE AQUEOUS PHASE CONTAINS DISSOLVED CATALYST AND ADDITIVES FOR SETTING UP A PH BELOW 7, AND THE ORGANIC PHASE IS A SELECTIVE SOLVENT FOR THE ALKYL-SUBSTITUTED PBENZOQUINONE FORMED IN THE OXIDATION. THE PROCESS ENABLES 2,3,6-TRIMETHYLHYDROQUINONE, AN IMPORTANT INTERMEDIATE IN THE SYNTHESIS OF VITMIN E, TO BE SEPARATED FROM MIXTURES OF METHYL-SUBSTITUTED HYDROQUINONES.

摘要:A new synthetic method of forming free radical polymerizable end terminal functionalized poloxamers and poloxamines in commercial scale batches which uses a binary system of inhibitors to eliminate the formation of high molecular weight impurities. It has also been surprisingly discovered that the inorganic impurities formed during the commercial scale synthetic process are removed by the use of resin materials.

摘要:A batch or continuous process produces highly pure 3,3',5,5'-tetra-t-butylbiphenol suitable as a starting material for the synthesis of 4,4'-biphenol. The process for producing 3,3',5,5'-tetra-t-butylbiphenol comprises conducting an oxidation coupling of purified 2,6-di-t-butylphenol(i) or crude 2,6-di-t-butylbiphenol(ii), said crude 2,6-di-t-butylphenol being obtained by reacting isobutylene with phenol in the presence of an aluminum catalyst, and removing the aluminum catalyst. The 2,6-di-t-butylphenol is oxidatively coupled in an alkali metal catalyst mixture comprising (1) an alkali metal catalyst and alkylphenols, or (2) alkali metal catalyst, alkylphenols and phenol to produce 3,3',5,5'-tetra-t-butylbiphenol. The oxidative coupling is conducted together with 10-30% by weight of phenol and/or t-butylphenol per 100% by weight of 2,6-di-t-butylphenol in the presence of an alkali metal catalyst.
