Abstract:
PROBLEM TO BE SOLVED: To provide a method in which a solvent can be effectively separated from a hydrogenation carry-out object that is obtained from catalytic hydrogenation and includes a water soluble hydrogenation product material, and that includes the solvent.SOLUTION: A method for separating a solvent from a hydrogenation carry-out object including a solvent is characterized in that the hydrogenation carry-out object is added with water, a phase that includes the solvent is separated and is returned to hydrogenation, in a method for separating the solvent from the hydrogenation carry-out object that includes a water soluble hydrogenation product material that has at least one alcohol, lactone, ether, lactam or an amino group in the solvent that cannot be mixed with water or cannot be mixed with water completely and has a boiling point of lower than 100°C, and that includes the solvent generated from a catalytic hydrogenation method.
Abstract:
A METHOD FOR DEHYDROGENATING PRIMARY OR SECONDARY ALCOHOLS HAVING 1 TO 12 CARBON ATOMS TO GIVE THE CORRESPONDING ALDEHYDES OR KETONES IN WHICH THE ALCOHOL IS BROUGHT INTO CONTACT WITH A CATALYTICALLY ACTIVE COMPOSITION COMPRISING AN ACTIVE COMPONENT OF THE FORMULA PDABIBYCZD, WHERE Y IS SELECTED FROM THE GROUP CONSISTING OF CO, RH, PT, AG, AU, AND ( Z IS SELECTED FROM THE GROUP CONSISTING OF NA, CS, MG, CA, BA, V, CR, W, FE, NI, CU, SB WHERE THE INDICES A, B, C AND D GIVE THE MASS RATIOS OF THE RESPECTIVE ELEMENTS TO ONE ANOTHER, WHERE A= 0.1 - 3, B = 0.1 - 3, 15 C = 0 - 3, D = 0 - 1.
