Abstract
1,4-butanediol moonooleate (BMO) and 1,4-butanediol,9-hydroxy-10-methoxy-monostearate (BHMMS) were synthesized. BMO was synthesized via Fisher Esterification between oleic acid from palm oil and 1,4-butanediol by using sulfuric acid as catalyst. Furthermore, BMO product was used as raw material for synthesis of BHMMS. BHMMS was synthesis via continuous two-step reaction i.e. epoxidation and hydroxylation. Characterizations of BMO and BHMMS products were conducted by analysis of ester number, acid number, iodine number and FTIR. In this research, obtained product of BMO and BHMMS were used as modifier of epoxy by reacting with epoxy and tolonate to produce polyurethane modified epoxy (PME) based on BMO (PMEBMO) and BHMMS (PMEBHMMS) from palm oil. Characterization of PME was conducted by determine residual isocyanate to calculate the isocyanate conversion and FTIR analysis. Curing process of PME products to obtain film sheets were done by adding versamid 140 as hardener. Characterizations of film sheets were conducted by determine of mechanical properties such as tensile strength and elongation at break. The result showed that mechanical properties of PME were higher than the mechanical properties of unmodified epoxy.
