标题:Synthesis of C-alkyl-triethylenediamines
发明人：NIEH EDWARD C Y
权利人:TEXACO DEVELOPMENT CORP
摘要:A liquid phase synthesis of C-alkyl-triethylenediamines involves heating to elevated temperatures of from about 200° C to 300° C a suitable N-(2-hydroxyalkyl) piperazine feedstock in the presence of a catalytic amount of a pentavalent acidic phosphorus compound and then recovering the C-alkyl-triethylenediamine product from the resulting reaction product mixture.

标题 :Process for the reduction of reducible groups and its use
发明人：ECKERT HEINER
权利人:ECKERT HEINER
摘要:The invention concerns a process for the reduction of groups containing unsaturated C,C-, C,N-,N,N-,N,O- bonds, especially of NO2-,NO-,NOH-,NR-,CN-,N3-,N2-groups or C=C or C-halogen- or acyl groups with hydrogen on MPc or with a suitable reduction agent on [MPc](-), whereby a platinum metal-phthalocyanine is used as the catalyst. It is possible that by the reversible change (control) of the oxidation phase z of the platinum metal from z>/=2 to z
