Abstract:
The present invention discloses a tertiary amine initiator and polymeric polyol compositions made therefrom useful for making polyurethane polymers, especially polyurethane foams. Said polyurethane polymer foams demonstrate a good balance of mechanical properties, physical properties and low emissions. The tertiary amine initiator is the reaction product of a dihydroxy tertiary amine and a polyhydroxy alcohol, such as the reaction product of N-methyl ethanolamine and glycerine.

Abstract:
Verfahren zur Herstellung von reinem Triethanolamin (TEOA) durch kontinuierliche destillative Auftrennung eines Ethanolamingemisches enthaltend TEOA und Diethanolamin (DEOA), wobei in einer Destillationskolonne (DEOA-Kolonne) DEOA abdestilliert wird und der anfallende Sumpfstrom enthaltend TEOA einer nachgeschaltenen Kolonne (TEOA-Kolonne) zugeführt wird, in der das reine TEOA als Seitenabzugsstrom entnommen wird, wobei die Verweilzeit des Ethanolamingemisches im Sumpf der DEOA-Kolonne
Abstract:
La dégradation d'une solution absorbante comportant des composés organiques munis d'une fonction aminé en solution aqueuse est sensiblement réduite en présence d'une faible quantité d'agents inhibiteurs de dégradation soufrés à groupement carboxyle définis par la formule générale :Formule (I). La solution absorbante est mise en oeuvre pour désacidifier un effluent gazeux.
Abstract:
The present invention is directed to a process for preparing a 2,26,6-d 4 -morpholine derivative represented by Structural Formula (I), or a salt thereof.
Abstract:
The present invention provides new ceramide analogs indicated as the compounds of formula (II). These novel analogs exhibit a significant anti cancerous effect and are therefore provided as a pharmaceutical composition for treating cell proliferative diseases, neurodegenerative disorders, metabolism-associated conditions, infectious diseases, and immune-related disorders. The invention further provides combined compositions and kits combining the novel ceramide analogs of formula (II) with an additional therapeutic agent.
Abstract:
Alkanolamine compositions are disclosed. The composition comprises an alkanolamine and hydroxylamine or hydrazine. Preferred alkanolamine includes diethanolamine, triethanolamine, and mixtures thereof. The composition of the invention has significantly reduced discoloration.
Abstract:
Disclosed is a method for producing ethyleneamines, in which ethylene oxide (EO) is continuously reacted with ammonia on an inorganic ion exchanger as a heterogeneous catalyst in anhydrous conditions in a first reaction stage, the obtained reaction product containing monoethanolamine (MEOA), diethanolamine (DEOA), and triethanolamine (TEOA) at a weight ratio MEOA: DEOA: TEOA = 80 - 94: 5.9 - 15: 0.1 - 5, and the reaction product is then continuously reacted with ammonia in the presence of hydrogen and a heterogeneous hydrogenation catalyst in a second reaction stage.
Abstract:
The invention relates to novel Acyl coenzyme-A mimics, compositions comprising ketone compounds, and methods useful for treating and preventing cardiovascular diseases, dyslipidemias, dysproteinemias, and glucose metabolism disorders comprising administering a composition comprising a ketone compound. The Acyl coenzyme-A mimics, compositions, and methods of the invention are also useful for treating and preventing Alzheimer's Disease, Syndrome X, peroxisome proliferator activated receptor-related disorders, septicemia, thrombotic disorders, obesity, pancreatitis, hypertension, renal disease, cancer, inflammation, bacterial infection and impotence. In certain embodiments, the Acyl coenzyme-A mimics, compositions, and methods of the invention are useful in combination therapy with other therapeutics, such as hypocholesterolemic and hypoglycemic agents.
