Physicochemical properties of synthesized bio-lubricants such as pour point (PP), cloud point (CP), viscosity, viscosity index (VI), oxidative stability, and corrosion resistant property were determined according to standard methods. Waste cooking oil (WCO) was chemically modified via epoxidation using H2O2 followed by transesterification with methanol and branched alcohols (isooctanol, isotridecanol and isooctadecanol) to produce bio-lubricants with improved oxidative stability and low temperature properties. The basic properties of jatropha biolubricant, pour point and viscosities are found comparable to other plant based biolubricant, namely palm oil and soybean based biolubricant.īio-lubricants derived from waste cooking oil with improved oxidation stability and low-temperature properties. C and Viscosity Index (VI) ranged from 178 to 183. Pour point for jatropha biolubricant was at -3 deg. The estimated activation energy was 3.94 kJ/mol. The synthesis was found to follow a second order reaction with overall rate constant of 1.49 x 10-1 (%wt/wt.min.deg. To maintain forward reaction, the excess amount of JME was maintained at 3.9:1 ratios to TMP. C due to insignificant improvement in biolubricant production. However, it was suggested that the optimum temperature of the reaction is at 150 deg. The conversion of JME to jatropha biolubricant was found to be the highest (47%) at 200 deg. The effects of temperature on the synthesis were studied at a range between 120 deg. The synthesis of jatropha biolubricant was performed by transesterification of jatropha methyl ester (JME) with trimethyl-ol-propane (TMP) with sodium methoxide (NaOCH3) catalyst. Jatropha oil has good potential as the renewable energy as well as lubricant feedstock.

To this end surface force and friction measurements were carried out by means of Atomic Force Microscopy, using hydrophilic and hydrophobic model surfaces in salt solutions of high ionic strength (≈ 150 mM) in presence of different biolubricants. As Ramli was developing his new BLOG some time ago and named it pramleeelvis BLOG little did he realized that there was some important coincidences in that name that contains the 3Es!What are the 3Es then?In Ramli’s 1st book that was published on 24thMarch,2006,Ramli wrote about the importance of the 3Es in Management and that 3Es stand for:1.The main objective of this thesis work was to gain understanding of the principles of biolubrication, focusing on synergistic effects between biolubricants. #BLOG RAHMAT AZIZOL PLUS#YES,DPS Trading have received good news from her counterpart in Jakarta about the availability of new Tudung designs and all the glittering and fanciful accessories!Please see all the photos and if you are interested to order,please email to to confirm all prices in RM plus availability of stock and date of delivery etcNote: Availability of stocks and confirmed prices will be made known later.Our prices will be the best and most reasonable for all.For enquiries,please tel hp:+60 (Ramli) or email atHere are the latest designs and accessories for Tudung. ![]() For those who frequently make a point to visit the many Trade Fairs and Exhibitions at Malaysia’s famous PWTC will realized the recently completed Food Pack,Rubber Plastic Mould&Die,SignTech and also the newly PROMAS exhibition at PWTC.This is the 21st time the Foodpack,Rubber Plas and Signtech Exhibition taking place in Malaysia having started in 1989 at Chinwoo Exhibition Hall in KL by the Founder/Managing Director of this ES Event Management Sdn.Bhd. ![]()
