摘要:脂族α,ω-二醇的氧化是生产有价值的α,ω-二酸或ω-羟基酸用于各种聚合物合成的潜在有趣途径.1,4-丁二醇(bdo),1,5-戊二醇(pdo)和1,6-己二醇(hdo)特别吸引人,因为它们可以从木质纤维素生物质中获得.在70 Bar或90oc的氧化锆上,在40 Bar的空气中,在一组au,Pt,Au-Pt和au-Pd催化剂上,在水中研究了这些二醇的水有氧氧化成相应的二酸.随着氧化的进行,金属催化剂的性质影响了产物的分布.连接末端醇基的碳链越长,二酸的收率越高.与au-pt / Zro相比,Bdo,Pdo和hdo的琥珀酸,戊二酸和己二酸的最佳产率分别达到83%,84%和96%2.在反应的早期,有一些证据表明α,ω-羟醛会脱羰.与hdo相比,1,2,6-己三醇中羟基取代基的存在显着降低了氧化速率.此外,在中等碱性介质(naoh /二醇= 2)中,相对于au / Zro 2(90-93%),P

摘要:Novel intermediates and method for the chemical synthesis of N-substituted 1,5-dideoxy-1,5-imino-L-fucitol derivatives are provided. A preferred intermediate is 1,5-dideoxy-1,5-imino-3, 4-O-isopropylidene-L-fucitol which is used to prepare the HIV inhibitor 1,5-dideoxy-1,5-imino-[N-ω-methyl caproate]-L-fucitol. These compounds are prepared in a short synthesis from the known compound 2,3-O-isopropylidene-D-lyxono-1,4-lactone or in a multi-step synthesis from D-galactose.

权利人:GONZALEZ RAMON
摘要:The use of microorganisms to make omega- and/or omega-1-functionalized products through an iterative carbon chain elongation pathway that we call a reverse beta oxidation pathway. The pathway uses omega-functionalized CoA thioesters as primers and acetyl-CoA as the extender unit in a non-decarboxylative Claisen condensation, and then uses beta oxidation or fatty acid synthesis enzymes to complete the cycle, via reductase, dehydratase and reductase reactions. Various termination enzymes that act on the functionalized beta-keto acyl-CoA intermediates of the pathway and produce omega or omega-1 functionalized products. The action of termination enzymes on such intermediates yield a large variety of products.

摘要:The invention relates to a method according to claim 1 for the commercial implementation of a pyrolysis, and to pyrolysis devices for the pyrolysis of pyrolysis stock used in this method. The pyrolysis stock contains a polymeric compound having at least one structural polyurethane unit of the formula (I), wherein Q is a hydrocarbon group with 2 to 8 carbon atoms, preferably 3 to 8 carbon atoms, and n represents a number from 2 to 4, most preferably 2, and -* represents a covalent bond to the polymer backbone. The method and the pyrolysis device according to the invention allow, even with higher compounds of pyrolysis stock an amount of pyrolysis product to be obtained that contains cleavage products which can be reused for the synthesis of polyurethane-containing material.
