ABSTRACT: Methyl Ester
Sulfonates surfactant is produced from sulphonation process between methyl ester
and sulphonating agent, such as NaHSO3.
The purpose of these research were to obtain the optimum conditions
(reaction temperature, sulphonation time, methanol concentration and
purification temperature) of sulphonation process in producing MES from Palm
Kernel Oil methyl ester and to investigate the characteristic of MES
produced. Measurements conducted
included iodine value and acid value.
The experimental design used was Response Surface Methode (RSM) and
Central Composite Design (CCD) of four factors.
The analysis of resulted response surface indicated that the optimum
conditions at MES production from methyl ester of PKO was obtained from the
reaction temperature of 96,5oC, the sulphonation time of 4,3 hours, the
methanol concentration of 26,6%, and the purification temperature of 45,5oC.
The result of validation of optimum condition showed the acid value of 16,32 mg
KOH/g sample and iodine value of 7,84 g iodine / 100 g sample.
