Abstract

The single stage solvent extraction of pepper oleoresin did not always give satisfactory results. It might be below or over the standard. To solve the problem the pepper was processed using two stages extraction. First the volatile oil was isolated by means of steam distillation and then the solvent extraction was conducted. To meet the standard qualification the volatile oil and resin were blended. It was found that the best solvent for oleoresin extraction was ethanol. It produced 15% oleoresin and 49% pipperine. The resin and pipperine produced from the distillation residue was more than those from ethylene dichloride extraction.

Abstract

The derivation of alpha-pinene into various compound had been studied for many years. The transformation of pinene into camphene was carried out by hydrochlorination process. The process waas in fluenced by several conditions such as temperature, time of reaction and the atmospheric pressure. When the temperature and atmospheric pressure had been fixed, the time of hydrochlorination have a great effect. It was found that oversaturated condition of HCl gas reduced the camphene yield. The optimum time of hydrochlorination process was 30 minutes if 50 ml of alpha-pinene was bubble with HCl gas at the rate of 20 ml perminute on standard condition.

Abstract

Acetone-butanol-etanol (ABE) mixture in fermentation broth drived from fermentation of empty bunch of palm fruit is still containing butyric and acetic acid.The mixture can be separated by into its components byfractional distillation based on their different boilling points.The presence of butyric and acetic acid in the broth liquid did not interfere the yield of distillation. It was beneficial to concentrate the ABE content before the real fractional distillation was taken place.By collecting 12% of the liquid through a simple distillation had increased the concentration of ABE mixture from 17.42 to 125.25g/1.Fractionation of concentrated ABE mixture at 45 to 65 degree C on 3:1 reflux ratio produced aceton with concentration 554.63 g/1 and purity 70.22% while those of etanol at 78 to 81 C on  30:1 reflux ratio produced 424.73 g/1 and purity 53.61%.The residue was consist of water and and water was distilled like a stem distillation,since butanol has higher boiling point than water and the distillate was separated base on their different density.The yield of butanol 709.15 g/1 and purity 87.57%.
