摘要:摘要 英文 法文 杂多酸 "H3+n[pmo12-Nvno40]-Aq"(表示为 Hpa-N;N = 2,3,8)能在二氧存在下催化醛氧化成羧酸,且产率非常高.研究考察了各种参数(如前体,溶剂,温度或催化剂/底物比例)对催化活性的影响.该过程对线性醛和芳香醛具有特别的选择性.在温和条件下,以 Hpa-2 为催化剂,己二醛与二氧发生氧化反应,生成己二酸和大量其他副产物.因此,人们对催化系统进行了多次改良,以提高其选择性.研究人员对助催化剂的效果进行了调查,发现在测试的各种助催化剂中,络合物 Ni(Acac)2 的效率最高,可产生 60% 的己二酸. H3+n[pmo12-Nvno40]-Aq "型杂多酸(表示为 Hpa-N;N = 2,3,8)在氧气存在的情况下催化醛氧化成羧酸,具有非常好的收率和高选择性.对各种参数,如前驱体,溶剂,温度和催化剂与底物的比例进行了研究.该催化过程对线性醛和芳香醛的选择性特别高.在催化剂中加入一定量的 Hpa-2 和氧气后,己二醛就能在不苛刻的条件下被氧化成己二酸,也能氧化成其他副产品.为了限制后续氧化,对催化系统进行了一些修改.在后一种情况下,研究了辅助催化剂对催化活性的影响.在测试的助催化剂中,我们发现 Ni(acac)2 复合物的催化效率最高,己二酸的收率为 60%.

摘要:A catalyst for producing an aryl ester of a carbonic or carboxylic acid is disclosed, which includes a microporous material containing a metal element belonging to group IV. This catalyst can be used as a heterogeneous catalyst to produce the aryl ester in high yield with industrial advantages. In order to produce the aryl ester using the catalyst, a carbonate or an aliphatic carboxylate is transesterified with an aromatic hydroxy compound, or an aryl carboxylate is transesterified with a carbonate, or an alkyl aryl carbonate is disproportionated by transesterification.

摘要:The present invention relates to polyurethane-urea elastomers with exceptional mechanical properties and enhanced elasticity based on molecular structure analysis. The present invention involves the synthesis of a polyurethane-urea elastomer using a combination of commercially available materials: (1) polyols with ultralow unsaturation and narrow polydispersity, (2) diisocyanates with symmetric steric conformation, and (3) bulky diamines between functional groups. The preparation method for the novel polyurethane-urea is disclosed. The subject elastomers have the highest reported elongation-at-break among known polyurethane elastomers.

发明人：MANIMARAN THANIKAVELU; STAHLY G PATRICK; HERNDON JR R CARL
权利人:ETHYL CORP
摘要:A process for obtaining a substantially pure enantiomer of an aryl-substituted aliphatic carboxylic acid is described. The process utilizes first an enantiomerically enriched mixture the of aryl-substituted aliphatic carboxylic acid obtained from kinetic resolution, diastereomeric crystallization or asymmetric synthesis processes. This enriched mixture is reacted with a base producing a salt that has the following properties: n 1) has at least one eutectic point; n 2) a composition that is not at the eutectic point; and n 3) a eutectic composition that is closer to the racemic composition than is the eutectic composition of said aryl-substituted carboxylic acid. n Substantially pure, enantiomeric salt is separated, leaving a mother liquor comprising the solvent and aryl-substituted aliphatic carboxylic acid enriched in the other enantiomer.

摘要:Novel hydroxamic acid compounds are disclosed. These hydroxamates inhibit peptidyl deformylase (PDF), an enzyme present in prokaryotes. The hydroxymates are useful as antimicrobials and antibiotics. The compounds of the invention display selective inhibition of peptidyl deformylase versus other metalloproteinases such as matrix metalloproteinases (MMPs). Methods of synthesis and of use of the compounds are also disclosed.
