-
Paragraph 0038-0040; 0042-0043, (2020/07/08)
The invention discloses a triazacyclohexane chromium trichloride coordination compound catalyst containing a secondary amine substituent, wherein the structure of the chromium coordination compound catalyst is represented by a formula (I), and R1 and R2 are C1-C10 alkyl. The catalyst is especially suitable for oligomerization reactions of ethylene, propylene, butene, hexene, octene, decene and other alpha-olefins, has the characteristics of high catalyst activity and selectivity, and has the advantages of simple synthesis route, accessible raw materials and low cost.

Capillary supercritical fluid chromatography/mass spectrometry of phenolic mannich bases with dimethyl ether modified ethane as the mobile phase
Fuchslueger, Ulf
, p. 2324 - 2333 (2007/10/03)
The analysis of phenolic Mannich bases-which are used as hardeners and accelerators for epoxy resins-by capillary supercritical fluid chromatography (SFC) with dimethyl ether modified ethane as the mobile phase is described. The elution properties of several different mobile phases with respect to amines are shown. SFC with UV detection is coupled via a custom-built interface to a mass spectrometer with atmospheric pressure chemical ionization. Two technically important Mannich bases prepared by different production processes are characterized and compared with respect to their byproducts. The role of dimethyl ether during the ionization process and the fragmentation of phenolic Mannich bases is discussed.
