Certain complex compounds were synthesized by physico-chemical characteristics of the oil were
the interaction of Mg(II), Ca(II) and Fe(III)
halides with the solvent extracting reagent,
Cyanex-272 i.e. bis (2,4,4-trimethylpentyl)
phosphinic acid as ligand. All the prepared
complexes have been characterized on the basis
of their molar masses, conductivity, magnetic
measurements and infrared and electronic
spectral studies. The other physico-chemical
properties e.g. colour, decomposition temperature
have also been ascertained.

with Cyclopentene in the Presence of p-

m-Cresol has been cycloalkylated with
cyclopentene in the presence of p-toluenesul-
phonic acid as catalyst. The effects of the variation
of temperature, molar ratio of m-cresol to
cyclopentene, time of reaction and amount of
catalyst have been investigated on the reaction and
cyclopentyl m-cresol has been obtained in high
yield.

utilizing safflower (Carthamus tinctorius) seed oil.

Studies were carried out on the preparation of oleo- 619 SAHA, M.; DEY, H.C.; KARIM, M.Z.;
resinous wood varnishes by utilizing safflower
(Carthamus tinctorius) seed oil. It was observed
that safflower seed grown under the soil-texture
and climatic condition of Bangladesh, contains
about 32 % golden yellow coloured drying oil. The
223
determined by the conventional methods and the
fatty acid compositions by GLC. From the results
it is evident that the oil can be used suitably in
paint and varnishes on account of its high linoleic
acid content (75 %) and higher iodine value (148).
The oleoresinous wood varnishes was prepared by
utilizing safflower seed oil in an open stainless
steel beaker by heating the oil with rosin and
glycerol. The cooking temperature was maintained
at 300° C for 1/2 an hour. Zinc oxide and lead
oxide were used as mould growth inhibitor and
catalyst respectively. The varnish thus prepared
was found to be water resistant and can be applied
on wood surface as lack free coating.

Bang. J. Sci. Ind. Res., 2006, 41(1 & 2), 83-88.
The oil composition of Cassia alata seed collected
from three different districts of Bangladesh was
investigated. All the seed samples contain about
3.2 % oil. The triglyceride component of the oil
varied from 91.5 to 92.0 % diglyceride from 3.4 to
3.9 % and monoglyceride from 1.5 to 2.1 %. The
lipid components were almost the same in all the
samples, the neutral lipid accounted for over 93 %
of the total lipids present. The analysis of the fatty
acid composition showed 25.6 % oleic acid. 45.5
% lmoleic acid, 18.7 % palmitic acid, 3.5 % stearic
acid, 3.4 % arachidic acid and 3.2 % behenic acid.
