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.

Abstract

This research aimed to know Picung/ Pangi (Pangium Edule Reinw) plant's potencies as raw material for frying oil and biodiesel alternative so that it can be used as extensive as palm and coconut oil. As this picung/pangi plants are widely consumed by Indonesian people, this plant is an interesting subject to be researched and studied on. The result of this research will be a great reference in increasing the utilization of Pangi Plant. The research method that is being used in this research for frying oil production is extraction using petroleum eter in laboratory scale and the yield then analyzed. The results presented shown that the density: 0.918 g/ml; water content: 0.0253%; free fatty acid (FFA) content: 2.53%; fat content: 51.468%; acid number: 0.33 mg KOH/g; Iodine number: 29.31 g Iod/100 g Oil; peroxide number: 4.124 meq/kg; and oil's color depends on the process used. The oil produced was then used for making biodiesel, which consist of two-step processes, esterification and transesterification. The result of this research shown that characteristics of biodiesel produced as follow: density: 0.888 g/ml; viscosity: 0.0006 g/cms; water content: 0.024%; free fatty acid (FFA) 0.3557%; Iodine number: 29.31 g Iod / 100 g Oil; scap number: 188.23 mg KOH/g; acid number 0.33 mg KOH/g; and Cetane number was 68.7. It is concluded that Picung/Pangi oil can be used as frying oil and biodiesel as an alternative fuel.
