标 题 :MOF synthesis method
发明人：NI ZHENG; MASEL RICHARD I
权利人:UNIV ILLINOIS
摘要:A rapid, simple and versatile metal organic framework molecule (MOF) synthesis method particularly adapted to make non-linear MOFs includes heating MOF precursors, such as a metal or metal oxide and an organic ligand, in a microwave oven for a period sufficient to achieve crystallization. Microwave-assisted MOF synthesis yields high quality MOF crystals in a reaction time ranging from about 5 seconds to about 2.5 minutes, compared to hours and days required in conventional solvothermal and hydrothermal methods. In addition, microwave assisted methods provide MOF materials with uniform crystal size and well-defined shape. Further, microwave synthesis of MOFs allows the size and shape of MOF crystals to be tailored for use in a wide range applications by manipulating reaction conditions. Secondary growth processes may also be employed to grow larger crystals using seeds obtained from microwave-assisted synthesis methods.

权利人:MINT BIOTECHNOLOGIES CO LTD
摘要:Provided in the present invention is polyester synthesis based on aspartic acid modification. A monomer of a unique structure of an imide ring is obtained based on aspartic acid and a dibasic acid likely to be cyclized, the monomer is based on the aspartic acid, can be derived from biomass, is low in cost and renewable, meets the requirement of sustainable development, and the unique structure of the monomer can regulate and control various properties of polyester materials, such as the mechanics, temperature resistance, hydrophilicity and hydrophobicity, and crystallization.

标题 :Recovery of alcohols from n-paraffins by pervaporation
发明人：DARNELL CHARLES P; KOVEAL RUSSELL J; CHEN TAN J; HO W S WINSTON
权利人:EXXON RESEARCH ENGINEERING CO
摘要:The present invention is a process for the recovery of normal alcohols, especially C 1 -C 20 n-alcohols, preferably n-C 4 -C 14 alcohols, most preferably n-C 6 -C 11 alcohols from n-paraffins by means of pervaporation through a membrane. The alcohols/paraffin feed mixture may be that produced in the Fischer-Tropsch synthesis process wherein mixtures of CO and H 2 are reacted to produce paraffin waxes and a minor but still valuable amount of alcohols.

标题:Process for preparing cyclobutane-1,2-dicarboxylic esters
发明人：BRUNNER ANDREAS
权利人:LONZA AG
摘要:Cyclobutane-1,2-dicarboxylic esters of the formula: ##STR1## in which R 1 is a C 1-8 -alkyl group, an optionally substituted mono- or bicyclic cycloaliphatic group having 3 to 10 ring carbon atoms, an optionally substituted aryl or arylalkyl group or an optionally substituted saturated heterocyclic group and R 2 is either C 1-4 -alkyl or both radicals R 2 together form a group of the formula --(CH 2 ) n --(n is 2 to 4), are prepared from the corresponding maleic or fumaric esters and ketene acetals in the presence of a Lewis acid and a sterically hindered base. The reaction is stereoselective when optically active maleic or fumaric esters are employed. The cyclobutane-1,2-dicarboxylic esters (I), in particular those having trans configuration, are intermediates in the synthesis of pharmaceutically active compounds.
