PENGARUH PENGGUNAAN PENYALUT BIOBLEND PS/PCL TERHADAP PELEPASAN ZAT AKTIF UREA GRANUL
ABSTRACT: The most widely used
surfactant is an anionic surfactant which is synthesized from petroleum namely
Linear Alkylbenzene sulphonate (LABS). Methyl Ester Sulfonate which is
currentlybeing developed. Surfactant can produced from palm oil methyl ester
via sulfonation sulfonate. When in this research using sodium metabisulphite.
The aims of this work is to synthesizeMethyl Ester Sulfonate surfactant from
Palm Oil Methyl Ester using Sodium Metabisulphiteand a catalyst Calcium Oxide.
The effects of time and the mole ratio are also investigated.Sulfonation
process carried out in 4, 5, 6 hours with mole ratio of 1: 0,5, 1:1, 1: 1,5,
temperatureof 80° C and with stirring speed of 450 rpm. It haven been found
that the surfactant producedhas density of (0.89490 g/cm3 - 0.89545 g/cm3),
viscosity (2.0323 cP - 2.1329 cP), pH (2,03 - 2,48), surface tension (32.60
mN/m - 33.60 mN/m), interfacial tension (30.45 mN/m - 30.94mN/m), and the
stability emulsion (59.17% - 89, 17%).
