Abstract

Surfactants (surface active agent) is a chemical compound used for reduce the surface tension of the liquid. Surfactants are divided into four groups: anionic, nonionic, cationic and amphoteric. The most widely used surfactant is an anionic surfactant which is synthesized from petroleum namely Linear Alkylbenzene sulphonate (LABS). LABS is not resistant to high salinity levels, not degradable, expensive and still imported. Methyl Ester Sulfonate is an anionic surfactant which is currently being developed. These surfactants can be produced from palm oil methyl ester. MES produced from sulfonation reaction with addition of sulfonate. Sulfonate used in this research using sodium metabisulphite. The aims synthesize surfactant Methyl Ester Sulfonate of Palm Oil Methyl Ester usingSodium Metabisulphite and a catalyst Calcium Oxide, and to study the effects of time and the mole ratio of the product produced. Palm Oil Methyl Ester obtained from PT. Cemerlang Eka Perkasa Dumai, Riau Province. Sulfonation process carried out at the time variation of 4, 5, 6 hours, the mole ratio of 1: 0,5, 1:1, 1: 1,5, temperature of 80° C and the stirring speed of 450 rpm. The density of MES (0.89490 g/cm3 - 0.89545 g/cm3), viscosity (2.0323 cP - 2.1329 cP), a pH (2,03 - 2,48), surface tension (32.60 mN/m - 33.60 mN/m), interfacial tension (30.45 mN/m - 30.94 mN/m), and the stability emulsion (59.17% - 89, 17%).Keywords: methyl ester, methyl ester sulfonate, sulfonated, surfactant

Abstract

Crude palm oil uses to term downstream industries in indonesia still at low, because of that we need to develop in downstream products. In addition, one of them which developed is fatty acid alkyl ester. Downstream products that included in fatty acid alkyl ester is plastisizer. Plastisizer is additive substance that added into polymer to increase flexibility and workability with esterification process. esterification is process between carboxiclic acid and alcohol to form ester and water as byproduct. In this research, plastisizer synthesized by esterification of oleic acid and isopropanol with activated natural zeolit as catalyst. This process was doing with variation of stirrer speed (175, 200 and 225 rpm) and composition of catalyst (12.5, 15 and 17.5%) also as fixed variable is temperature of reaction at 75 - 80°C, the reaction time of 6 hours and molar ratio of 1:9 oleic acid based. From esterification analysis result we can look that strirrer speed  and composition of catalyst influenced rate of reaction to reach the equlibrium. The best operating condition in this reasearch has got at 17.5% composition of catalyst and 200 rpm of stirrer speed that produce 59.27% conversion. Product that has been produced is methyl ethyl ester, oleic acid, Methyl Ester, Dihidroxypropyl Ester and Isopropyl Ester. Characteriztion of plastisizer that has produced from this research is viscosity at (200 C ) is 4,360 – 5,882 mPa.s and specific gravity  (200 C) is 0,785 – 0,844.  Keywords: Esterification, H-Zeolit , Isopropanol, Oleic Acid, Plasticizer
