Penentuan Kadar Air dan Kadar Abu dari Gliserin yang di Diproduksi PT Sinar Oleochemical International Medan

Abstract

Existence of water and dusty in glycerine make the quality of glycerine become to go down. This matter caused water and ash that material which not expected in glycerine making glycerine decrease its perity. In This Case PT. Light Oleochemical International- Field conduct the analysis to determine the rate irrigate and dusty rate in glycerine. Analyse the rate irrigate conducted with the method of Karl Fisher of pursuant to electrolyse principle where twin platinum used as electrode. Later, then water will react by iodine dioxide sulphur with the existence of basa and alcohol. and used dusty rate Determination to know the perity storey;level from glycerine. In dusty rate determination use the kiln at temperature 600° C and use the balance technique. Standard PT. Light of Oleochemical International- Field for the rate of irrigate maximum 0,05 % and for the rate of dusty 0.01 %, where result analyse which have been done to indicate that the rate irrigate below/under 0,05 % and dusty rate below/under 0,01 % and result of this crucible as according to standard which have been specified by company.
