Abstract

Bio-lubricant synthesis from catfish waste oil is purposed to modify the useless oil to be a bio-lubricant. That function’s is to protect the engine component from wear. Esterification with ethylene glycol toward acid from catfish waste oil hydrolysis with mole ratio 1:4 for 4 hours, with variation of temperature and mixing speed. The waste extracted by rendering, oil’s boiling point is 270oC, the viscosity is 15,69 mPa s. The oil hydrolyzed at 80 oC with adding of HCl concentrated catalyst 0,1% weight/weight for 8 hours and produce the acid. That’s polymerized by adding benzoyl peroxide as 0,2% for 5 hours at 120 oC. Then, polyestherification by adding ethylene glycol in mole ratios of 1:4, for 4 hours at 120 oC, 150 oC, 1800C, and mixing speed at 150 rpm, 180 rpm, and 210 rpm. The resulting has its density, it’s 0,942 gr/m, viscosity is 61,081 mPa.s, flame point is 290,5oC, boiling point is 290 oC with yield of 66,5%. The product has a commercial standard (density is 0,92 gr/ml and viscosity is >41,1 mPa.s). The best result from this research was obtained by mole ratio 1:4 for 4 hours; the mixing speed is 150 rpm at 150oC.Keyword: bio-lubricant, oil of catfish waste

Abstract

Oil palm commodity has a strategic role in the national economy. In the development of the palm oil industry, the necessary diversification of oil palm products needed by using the esterification reaction. One of the products of the oil palm which on development now is a fatty acid alkyl esters. Products that include the type of fatty acid alkyl ester is plasticizer. In this study, the plasticizer is synthesized by esterification of oleic acid and butanol, using activated natural zeolite catalysts. This research aims to study the influence of H-Zeolite catalyst composition and stirring speed on synthesis plasticizer butyl oleate, and determining the characteristics of the plasticizer butyl oleate which generated through analysis of test products. The process is using the variation of H-Zeolite catalyst composition (12.5%, 15%, 17.5%) based on oleic acid and stirring speed (175 rpm, 200 rpm, 225 rpm), with a fixed variable, the reaction temperature of 1100 C, the process time is 6 hours and the reaction molar ratio of 1: 9. From the analysis of the results showed that the esterification of H-Zeolite catalyst composition and stirring speed affects the conversion of the resulting products. The best operating conditions obtained in this study is the H-Zeolite catalyst composition of 17.5% and a stirring speed of 200 rpm which produces a reaction conversion of 74.50%. Characteristics plasticizer generated in this study is consistent with the characteristics of commercial plasticizers which Viscosity (200 C) 8.62 to 9.07 mPa.s and Specific Gravity (200 C) from 0.886 to 0.901.Keywords: Butyl Oleate, Esterification, H-Zeolite and Plasticizer

Abstract

Catfish waste can be processed into fat or fish oil that can be used as a source of raw material for plasticizers with the trans-esterification reaction. Transesterification reaction is a reaction between oils (triglycerides) with the alcohol that produces Fatty acid alkyl esters. Products that include the type of fatty acid alkyl ester is a plasticizer. Plasticizer additive compound that is added to hard or rigid resin can improve the flexibility and workability. In this study, the plasticizer is synthesized by transesterification of waste oil catfish and butanediol, using natural zeolite catalyst activated. The process is done with a variety of molar ratio (1: 2, 1: 4, and 1: 6) and H-zeolite catalyst composition (10%, 15%, and 20%) of waste oil based ikana catfish, with a fixed variable reaction temperature 145- 1500C, stirring speed of 200 rpm and reaction time of 6 hours. From the analysis of the results shows that the transesterification and the molar ratio of H-zeolite catalyst composition affects the conversion of the resulting product. The highest operating conditions obtained in this study is the molar ratio of 1: 4 and H-zeolite catalyst composition of 15% which resulted in the conversion reaction of 25.35%. Characteristics plasticizer generated in this study are Viscosity (200 C) 0.910 mPa.s and Specific Gravity (200 C) 0.918.   Keywords: Plasticizer, Trans-esterification, Waste Oil Catfish, Butanediol, H-Zeolite

Abstract

The amount of palm oil feedstock in Indonesia, encourages the development of palm oil industry product diversification. One alternative for providing value-added palm oil by esterification of oleic acid is contained in palm oil became known as butyl oleate plasticizers. Plasticizer is an additive compound added to polymer to improve flexibility and workabilitas. Step of this research is the preparation of H-zeolite catalysts and synthesis of the plasticizer butyl oleate esterification using natural zeolite catalysts are activated to H-zeolites with varying reaction time (6, 9 and 12 hours) and the molar ratio of oleic acid and butanol (1: 6 , 1: 9 and 1:12) with the permanent variable stirring speed of 200 rpm, temperature of 108-112 ° C and catalyst-based as much as 15% oleic acid. From the test results showed that the reaction time and the molar ratio of the plasticizer effect on the synthesis of butyl oleate. Obtained value of 0.862 specific gravity and viscosity of 8.39 mPa by showing that the specific gravity and viscosity plasticizer produced meets the standards of commercial plasitisizer namely 0.862 to 0.928 and from 8.2 to 9.4. The highest achievement in this research was 76.73% with a molar ratio of 1:12 for 12 hours process.Keywords: Esterification, H-zeolites, Oils, Plasticizers
