METHOD FOR CATALYZING REACTION OF EPOXIDE COMPOUND AND CARBON DIOXIDE WITH CATALYST
摘要:
A method for catalyzing a reaction of an epoxide compound and carbon dioxide with a catalyst. The catalyst comprises at least one compound of formula (1):
where R is selected from an alkyl group, an alkenyl group, a halohydrocarbyl group, an aromatic hydrocarbyl group, an imidazolyl group, or a heteroaromatic hydrocarbyl group; X is selected from halogens; B is selected from nitrogen, or phosphorus; A is selected from any of the following formulae with a sign * representing a bonding position:

Heats of solution and viscosity B coefficients, for cyclic mono(quaternary ammonium) salts, (CH3)2N(CH2)nBr (n=4–6) and cyclic bis(quaternary ammonium) salts, (Remark: Graphics omitted.) (n=1–3) in water were measured, and the effect of structural changes in the solvent water upon the dissolution of both series of electrolytes is discussed.

of organic ionic materials of the dicyano(nitroso)methanideanion is reported. Six of the compounds are room‐temperature ionicliquids with low viscosities, which is a physicalproperty highly desired for many synthetic and electrochemical applications. In addition, use of dimethylpyrrolidinium and tetramethylammonium cations yield the first reported dicyano(nitroso)methanide organic ionic plastic crystals

Die Erfindung betrifft ein Verfahren zur Herstellung von Naphthalinsulfochloriden durch Umsetzung der Alkalimetall-oder Ammoniumsalze der Naphthalinsulfonsäuren mit Thionylchlorid in Gegenwart von katalytisch wirksamen Substanzen und gegebenenfalls in Gegenwart von inerten Lösungs-oder Verdünnungsmitteln, das dadurch gekennzeichnet ist, daß man die Umsetzung in Gegenwart von gegebenenfalls substituierten Pyridinen, tert. aliphatischen Aminen, sekundären Amidinen und/oder quartären Ammoniumsalzen durchführt. Die Naphthalinsulfochloride dienen u.a. als Ausgangsprodukte für die Herstellung von Azofarbstoffen.
