In This Research Studied The solubility of Succinic acid in water +
THF mixtures by astatic analytical technique using the acid–base
titration method at temperatures ranging from 298.15 to 333.15 K
and atmospheric pressure.
Tow compounds have been synthesised: tetra butyl ammonium
alginate and dodecanoate sodium alginate ester.
The synthesis of compound (1) by transferring
sodium alginate to Alginic acid and then adjusted by tetra-butyl
ammonium hydroxide. The comp
ound (2) was synthesised from
tetra-butyl ammonium alginate according to Fisherest erification,
between tetra-butylammonium alginate and dodecanoic acid and
using (Amberlyst-15) as a hetrogeneous acid catalyst, and then the
product react with sodium carbonate.
