标题:从头设计级联生物催化一锅法合成环己烷中的1,6-己二醇
摘要:1,6-己二醇(hdo)是聚合物工业中的重要前体.当前生产hdo的工业路线涉及以环己烷(ch)为起始原料的能源密集型和危险的多级(四锅四步)化学反应,这会导致严重的环境问题.在这里,我们报道了在温和条件下以一锅一步的方式将ch生物转化为hdo的生物催化级联过程的发展.这种级联生物催化是通过使用由三个大肠杆菌细胞模块组成的微生物联盟来进行的,每个模块都包含必需的酶.并行设计具有指定功能的细胞模块,然后组合以构建用于生物转化的大肠杆菌聚生体.工程包含相应细胞模块的大肠杆菌联合体不仅将ch或环己醇有效地转化为hdo,而且将其他环烷烃或环烷醇有效地转化为相关的二元醇.总之,新开发的生物催化工艺为制造hdo和相关二元醇的当前工业工艺提供了有希望的替代方法.

发明人：ATTIG THOMAS G; GRAHAM ANNE M; PESA FREDERICK A
权利人:STANDARD OIL CO OHIO
摘要:A process for producing an ester is disclosed comprising contacting a gaseous reactant containing at least one organic hydroxy compound and a mixture of carbon monoxide and hydrogen with an ester synthesis catalyst of the formula MaAbRuCucNzOx wherein M is selected from the group consisting of Ce, Cr, Fe, Mn and mixtures thereof, A is an alkali metal, alkaline earth metal or mixture thereof, a is from 0 to about 1, b is from 0.002 to about 10, c is from 0.2 to about 20, z is from 0 to about 196 by weight, x is the number of oxygens needed to fulfill the valence requirements of the other elements. The organic hydroxy compound can be provided separately or formed by contacting a mixture of carbon monoxide and hydrogen with an alcohol synthesis catalyst at an elevated temperature and pressure. The alcohol synthesis catalyst and ester synthesis catalyst can be in tandem or mixed.

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.
