标题:Process for the selective synthesis of ethylene diamines
发明人：MARSELLA JOHN A
权利人:AIR PROD & CHEM
摘要:The present invention is a process for the selective synthesis of alkanediamines by reacting a secondary amine with an alkanediol. High conversions and high selectivity for the production of alkanediamines is achieved by carrying out the reaction in the presence of a compound or complex of ruthenium in the absence of an organic phosphine co-catalyst.

标 题 :Method for the synchronous absorption of carbon dioxide from flue gas and synthesis of dialkyl carbonates and alkylene carbonates

摘要:The invention relates to a synchronous CCU method (carbon dioxide capture and utilisation) for the absorption of carbon dioxide from flue gas and other CO 2 -containing substance sources and simultaneous synthesis of dialkyl carbonates and alkylene carbonates. The general subject matter of the invention is, in terms of a 'carbon dioxide capture' on the one hand, the absorption of CO 2 from flue gas and other CO 2 -containing substance sources with ammonia and/or amines to form ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates and, in terms of a 'carbon dioxide utilisation' on the other hand, the reaction of ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates with aliphatic, alicyclic or unsaturated alcohols, and including unsaturated aromatic alcohols to give dialkyl carbonates or alkylene carbonates in such a form that the CO 2 n absorption agent is re-released and fed back into the repetitive process again. A repetitive process control is extremely energy and CO 2 n efficient.

标题:Method for the synthesis of sucrose-6-esters
发明人：CLARK JASON D; LEMAY JR RICHARD R
权利人:TATE & LYLE PLC
摘要:There is described a process for the synthesis of a sucrose-6-ester comprising: (a) reacting a mixture comprising sucrose and a polar aprotic solvent with an organotin-based acylation promoter, while adding a solvent capable of removing water by co-distillation, and removing water by co-distillation, to afford a first reaction mixture which is substantially free from water, followed by (b) adding a carboxylic anhydride to said first reaction mixture to afford a second reaction mixture, and maintaining said second reaction mixture at a temperature and for a period of time sufficient to produce a sucrose-6-ester, characterised in that step (a) is performed at a temperature of from 85 to 125° C. and at a pressure of from 20 to 80 kPa. In the most preferred embodiment, the polar aprotic solvent is DMF, the solvent capable of removing water by co-distillation is cyclohexane, the organotion-based acylation promoter is a 1,3-diacyloxy-1,1,3,3-tetrabutyldistannoxane, and step (a) is performed at approximately 97° C., and approximately 50 kpa, until the weight ratio of tin to water in the first reaction mixture is greater than about 26, when the tin content is measured by X-Ray Fluoresence Analyzer, and the water content is measured by the Karl-Fischer method.

标题 :Process for the selective synthesis of tertiary alkanolamines
发明人：MARSELLA JOHN A
权利人:AIR PRODUCTS AND CHAMICALS INC
摘要:The present invention is a process for the synthesis of tertiary alkanolamines by reacting a secondary amine with an alkanediol. High selectivity for the production of alkanolamines is achieved by carrying out the reaction in the presence of a compound or complex of ruthenium in chemical combination or in admixture with an organic phosphine ligand. The organic phosphine ligand is present in an amount such that the ratio of gram mole ligand/gram atom ruthenium is greater than 5.

摘要:The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of a specific type and of at least one Bransted acid or in the presence a specific chiral compound having a Bransted acid functional group in the molecule.
