Putra, R.W. 2010. Synthesis of Nickel Complexes Compound with Carboxil Ligan
from Crude Palm Oil and Their Potential Test for Waxs flame Coloring.

Key words: palm oil, carboxyl ligan, nickel complexes compound, waxs coloring

Complexes compound consist of cental ion and ligand. Central ion is metal
ion from alkali, alkali tanah, and transition metal. Ligand is anion or nautral molecul.
Now much synthese compound complexes with ligand from world material. World
material used for ligand must have atom free electron pairs which can donor pass.
One of world material used as ligand is carboxil anion. Carboxil anion have carboxil
group which can free electron pairs from oxygen atom to central atom so can function
as ligand. Carboxil anion obtain from oil, like coconut oil, Jatroha Curcas Linn oil,
and palm oil. Complexes compound synthese can used as compound material of waxs
so coloring produce result is interest like flame coloring of metal kation in used. This
research synthese nickel complexes with carboxil ligand whice give flame coloring if
flamed so can increase aesthetics price of waxs. Purpose this research is synthesis
nickel complexe compound with carboxil ligand with trans-saponification reaction
between sodium soap and nickel(II) chloride and then characterization until their
potential test for waxs flame coloring.

This research is consist of three steps that is: (1) synthesis, include two steps
that is sodium soap by saponification reaction between crude palm oil with sodium
hydroxide and nickel carboxyl complexe compound’s by trans-saponification reaction
between sodium soap and nickel(II) chloride; (2) characterization by determining
melting point, analyze of nickel metal with X-Ray Fluorescence (XRF), identification
of cluster fungtion with infrared spectroscopy, and solubility test along with magnetic
susceptible test with Magnetic Susceptibility Balances (MSB); (3) Application, added
nickel carboxyl complexe compound’s into paraffin with certain ratioand then flame
colour test with nichrome

The result of this research are : (1) sodium soap’s color is white; solved inside
water, octanol, glycerol, and compounds paraffin-octanol; dissolved inside n-heksane,
melting point 91-92 oC; and yield is 71,52%. (2) Nickel carboxyl complexe
compound’s color is green; dissolve inside water, glycerol, and n-heksane; solve
inside octanol and compounds paraffin-octanol (2:1); melting point 115-124 oC; and
yield is 70,27%. (3) Compound of synthesis product have parramgnetic
characteristic with μeff = 2,20 BM. (4) The flame’s test complexe compound with
nichrome and compounding with paraffin is red.
