摘要:酵母torulopsis Gropengiesseri将长链烷烃转化为糖脂,其中糖脂掺入了烷烃的氧化衍生物.源自c 12-C 24的糖脂脂质成分的比较烷烃,各种氧化的烷烃衍生物以及一系列的β-烷氧基丙酸甲酯表明,烷烃代谢的主要途径涉及烷烃1-醇的形成,随后将其脱氢为相应的链烷酸.这些酸通过β-氧化或通过羟基化代谢以反应生成ω-羟基酸(随后是αω-二羧酸),并通过立体有择羟基化代谢成ω-1-羟基酸.通过结合到糖脂中,可以保护氧化的链烷酸免于进一步降解.链烷酸的链长决定(i)β-氧化或羟基化是主要反应,以及(II)羟基化主要发生在ω-或ω-1-位.当羟基化位点和羧基被14个亚甲基链隔开时,链烷酸的ω-和ω-1-羟基化效率最高.提出这些羟基化可以通过单一酶来实现.烷烃代谢的次要途径涉及形成烷烃-2-醇,其被掺入糖脂中而不被氧化代谢.长链烷-1-烯的发酵产生糖脂,其掺入衍生自烷-1-烯的ω-1-羟基

摘要:The present invention relates to the synthesis of di(hydroxymethyl)tetrahydrofuran (DHMTHF) and the preparation of trans-enriched mixtures of DHMTHF. The invention further refers to polyester polyols which are obtained by reaction of cis/trans DHMTHF mixtures with a dicarboxylic acid. The invention further relates to polyurethanes and compositions containing a polyester polyol comprising DHMTHF, in particular to such polyurethane-containing (adhesive) compositions.

标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks

摘要:Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.

标 题:Process for the synthesis of aliphatic dialkyl esters from vegetable oils
发明人：BASTIOLI CATIA; CAPUZZI LUIGI; DIGIOIA FRANCESCA
权利人:NOVAMONT SPA
摘要:This invention relates to a process for obtaining highly pure aliphatic dialkyl esters of saturated dicarboxylic acids from vegetable oils, which can advantageously be used in polymerization. The process comprises the steps of reacting with an aliphatic alcohol a triglycerides mixture containing at least one triglyceride of at least one saturated dicarboxylic acid in the presence of one or more catalysts capable of catalyzing the esterification and transesterification reactions, and separating the dialkyl esters of saturated dicarboxylic acids from the reaction mixture thus obtained.
