标题:Method for the continuous purification by distillation of 1,2-propylene glycol that accumulates during the synthesis of propylene oxide without coupling products

权利人:BASF AG
摘要:The invention relates to a continuously operated process for the purification by distillation of the 1,2-propylene glycol formed as by-product in the synthesis of propylene oxide, wherein the mixture formed in the synthesis which contains the 1,2-propylene glycol is separated in a dividing wall column into low-, intermediate- and high-boiling fractions and the 1,2-propylene glycol is taken off as intermediate boiler at the side offtake of the column.

标 题:Synthesis of a dendritic polyalcohol

权利人:PERSTORP AB; IHRE HENRIK; HULT ANDERS
摘要:A process for a double stage convergent synthesis of a polymeric polyalcohol substantially and preferably built up from polyester units and composed of a monomeric or polymeric core to which at least one hyperbranched dendritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymeric or monomeric branching chain extender having three reactive functions of which two are hydroxyl groups and one is a carboxyl group. The two hydroxyl groups of the branching chain extender is in a first step ketal protected by reacting said two hydroxyl groups with a ketal. A second step includes protection of the carboxyl group of said branching chain extender. The ketal protected branching chain extender and the carboxyl protected chain extender are then employed for repeated addition in a number of step yielding a predetermined number of branching generations. The thus synthesized dendron is finally added to a core having reactive hydroxyl or epoxide groups and the ketal protected hydroxyl groups are optionally deprotected.

标 题:Process for the preparation of polyamines from N-monoaryl-N',N'-dialkyl urea compounds and their use for the synthesis of polyurethanes
发明人：RASSHOFER WERNER; GROEGLER GERHARD
权利人:BAYER AG
摘要:This invention relates to an improved process for the preparation of aromatic polyamines containing urethane and/or biuret and/or urea and/or isocyanurate groups and preferably also ether groups by the hydrolysis of poly-N-monoaryl-N',N'-dialkyl urea compounds (1-aryl-3,3-dialkyl ureas). The ureas are obtained by the reaction of secondary aliphatic, cycloaliphatic or saturated heterocyclic amines with divalent to tetravalent isocyanate compounds containing isocyanate end groups attached to aromatic residues. The ureas correspond to the general formula: wherein R1, R2 denote alkyl or cycloalkyl groups, or together form a ring and A denotes a divalent to tetravalent residue attached to the ureas by aromatic groups. Hydrolysis is carried out in the presence of water and up to two equivalents of a base containing hydroxide ions and/or up to two equivalents of a compound containing tertiary amino groups, optionally in the presence of solvents. The use of the polyamines obtained by this process for the synthesis of polyurethanes is also described.

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.

标 题:One pot synthesis of 5,10-dihydrophenazine compounds and 5,10-substituted dihydrophenazines
发明人：GIRI PUNAM; BYKER HARLAN J; BAUMANN KELVIN L
权利人:GENTEX CORP
摘要:Dihydrophenazines and bis(dihydrophenazines) are prepared in high yield under commercially viable reaction conditions by reacting a catechol with a 1,2-diaminoaryl compound, wherein either the catechol or the 1,2-diaminoaryl compound is provided in at least 50% molar stoichiometric excess. The product may be oxidized to the corresponding phenazine, but is preferably derivatized at one or both of the 5,10-positions to form a monosubstituted or disubstituted dihydrophenazine or bis(dihydrophenazine). Most preferably, 5,10-dialkyl-5,10-dihydrophenazines are prepared starting from catechol and 1,2-diaminoaryl compound in a one pot synthesis. The products are useful as dyes, and in particular as chromophores in electrochromic systems.
