Abstract

Vol 7 No 2ABSTRACTEsterification reaction is a reaction between fatty acids or carboxylic acids with alcohols toesters. Fatty acid (oleic acid) sourced from palm oil. One alternative to increase the economicvalue of palm oil is oleic acid esterification into oleic butyl known as plasticizers. Plasticizeradditives are compounds added to polymers to improve its flexibility and workabilitas. Thisstudy aims to study the effect of reaction time and molar ratio of the plasticizer synthesis oleicbutyl and identify the plasticizer oleic butyl. In this study, the first step is preparation H-Zeolitecatalyst, then synthesis of plasticizer butyl oleic esterification using natural zeolite catalystswere activated to H-zeolites with variables in the reaction time (6, 9 and 12 hours) and themolar ratio of oleic acid and butanol (1: 6, 1: 9 and 1:12) with the permanent variable stirringspeed of 200 rpm, 108-112 ° C of temperature and the catalyst were 15% oleic acid-based. Fromthe test results obtained 0.862 specific gravity, viscosity of 8.39 mPa and showed that thespecific gravity and viscosity of the resulting plasticizer has commercial plasticizer standardnamely 0.862 to 0.928 and from 8.2 to 9.4.

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 currently being 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 synthesize Methyl Ester Sulfonate surfactant from Palm Oil Methyl Ester using Sodium Metabisulphite and 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, temperature of 80° C and with stirring speed of 450 rpm. It haven been found that the surfactant produced has 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 - 30.94 mN/m), and the stability emulsion (59.17% - 89, 17%).

Abstract

Diversity of palm oil product in Indonesia is still limited, therefore it is needed to take an advantage of the development of downstream product of crude palm oil by esterification reaction. Esterification reaction is a reaction between carboxylic acid and alcohol to form ester. One of the emerging downstream product fatty acid alkyl ester is plasticizer. Plasticizer is an additive compound added to polymer to improve flexibility and workability. The purpose of this research was conducted to study the effect of reaction time and mole ratio and identify product of plasticizers isopropyl linoleic. In this research, plasticizer was synthesized by esterification of linoleic acid and isopropanol, using activated natural zeolite catalyst. The process was done with a variation of reaction time (4, 6, and 8 hours) and mole ratio (1: 6, 1: 9, and 1:12), with reaction temperature at  80 °C,  stirring speed at 200 rpm and 15% of composition of linoleic acid based catalyst as fixed variables. From the analysis of the results showed that the esterification reaction time and mole ratio affect the product conversion. The best operating condition obtained  in this research was 4 hours of reaction time and 1:12 of mole ratio which resulted the conversion of reaction was 67.09%. Characteristics of plasticizer produced from this research were viscosity (at 20 °C) 2.405 to 2.803 mPa.s and Specific Gravity (at 20 °C) from 0.863 to 0.872.
